Council Approval Guide 2026

Council Approval for Renovations Australia DA, CDC & Exempt Development Guide 2026

Complete guide to DA, CC, and exempt development. Understand when you need approval, costs, timelines, and application process by Australian state.

Three Council Approval Pathways Australia 2026 Complete Breakdown: Australian building regulations provide three distinct approval pathways for renovation work - Development Application (DA) for complex projects not meeting standard codes, Complying Development Certificate (CDC) for straightforward work meeting prescriptive building standards, and Exempt Development requiring no approval for minor internal work and repairs. Understanding which pathway applies to specific renovation prevents costly delays, fines $5,000-$800,000, and potential demolition orders for unapproved work.

Development Application (DA) Full Council Assessment Requirements: DA required for complex renovation projects not meeting complying development standards including second storey additions causing overlooking concerns and visual impact, large extensions exceeding 40-50sqm complying limits requiring full council assessment, heritage property alterations where heritage overlay removes most exemptions requiring heritage impact statement, front fences over 1.2m high affecting street character, significant external changes altering building appearance, change of use converting residential to commercial or home business, work in bushfire prone areas requiring bushfire attack level assessment, projects in flood zones requiring flood impact assessment. DA process involves council planner assessment checking compliance with local planning controls LEP and DCP, setback requirements typically 900mm side 6m rear varying by zone, height limits residential typically 8.5-9m varying by council, floor space ratio controls limiting total building area, neighbourhood character assessment ensuring design consistent with streetscape, neighbour notification period 14-21 days allowing objections and submissions, council may request additional information requiring response within 7-14 days to avoid delays extending timeline 2-6 weeks, council officer prepares assessment report with recommendation approve with conditions or refuse, council determines application within statutory timeframes though complex applications can extend significantly. DA costs vary by state and project value: NSW $2,000-$6,000+ calculated on estimated construction cost typically 0.5-1% of project value, VIC planning permit $1,800-$5,000+ depending on council and project complexity, QLD development permit $2,500-$7,000+ with additional referral fees if state agency involvement required, professional fees additional with architect plans $3,000-$10,000, BASIX certificate NSW $150-$300 for energy water efficiency compliance extensions over 50sqm, structural engineer reports $1,500-$3,500 for two storey or structural changes, surveyor site plan $800-$1,500 showing boundaries existing structures, heritage consultant report $2,000-$5,000 if heritage listed property, total professional costs $5,000-$25,000+ depending on project complexity. DA timeline standard residential alterations 8-16 weeks from lodgement to determination, complex projects or projects with objections 12-20 weeks, heritage projects 12-20+ weeks requiring extensive documentation and heritage committee review, projects requiring council committee determination rather than delegated authority add 2-4 weeks for committee meeting cycle, public notification adds 14-21 days minimum, requests for additional information extend timeline 2-6 weeks depending on response time and information complexity. DA approval includes consent conditions that must be satisfied before commencing work such as obtain Construction Certificate, provide Long Service Levy payment, submit detailed stormwater plans, arrange dilapidation reports for adjoining properties if excavation required, notify adjoining owners of works, appoint Principal Certifying Authority.

Complying Development Certificate (CDC) Fast-Track Approval Prescriptive Standards: CDC fast-track approval pathway for straightforward residential work meeting strict prescriptive standards defined in State Environmental Planning Policy (SEPP) or local codes, processed by private certifier or council typically 10-20 days significantly faster than DA 8-16 weeks, no neighbour notification or consultation required reducing objection risks and delays, combines development approval and construction approval in single certificate streamlining process. CDC eligible renovations meeting all criteria: carport under 40sqm single storey meeting setbacks 900mm-1.5m from side boundary 6m from rear boundary maximum height 3.6-4.2m depending on roof pitch, garage under 50sqm meeting same setback and height requirements, deck or patio 10-25sqm area under 1m above ground level meeting setback requirements 900mm from boundary, internal alterations including removing non-structural walls or load-bearing walls with engineer certification, single storey room addition under 40sqm attached to existing dwelling meeting all setback height floor space ratio controls, swimming pool meeting Australian Standard AS1926 pool fencing requirements minimum 1.2m height non-climbable zone, granny flat under 60sqm in NSW on lots minimum 450sqm meeting specific design standards. CDC exclusions where pathway not available: heritage conservation areas or heritage listed properties where heritage significance requires case-by-case assessment, bushfire prone land where bushfire protection measures require individual assessment, flood planning areas where flood impact requires hydraulic assessment, environmentally sensitive areas wetlands riparian corridors threatened species habitat, land with contamination requiring remediation, coastal areas within coastal zone. CDC requirements all standards must be met without variation: setbacks must comply exactly no discretion for minor variations unlike DA where council can approve variations, height limits strict maximum heights typically 8.5-9m for two storey 4.2m for single storey outbuildings, building materials complying with character requirements often prohibiting certain materials in heritage-style areas, site coverage maximum percentage of lot that can be covered by buildings typically 50-60% residential, landscaped area minimum percentage of lot remaining as landscaped area typically 40-50%. CDC costs and process: private certifier fees $1,500-$3,500 for CDC application including plans assessment and determination, council fees similar range if lodging CDC with council rather than private certifier though council processing slower 6-8 weeks versus private certifier 2-4 weeks, professional fees for plans preparation draftsperson or building designer $800-$1,500 for simple carport garage deck plans, architect $2,000-$5,000 for extension or granny flat plans requiring more complex documentation, structural engineer certification $800-$2,000 if removing load-bearing walls or structural alterations, surveyor site plan $800-$1,500 if existing survey not available. CDC process timeline: engage private certifier or contact council to confirm CDC eligibility for project, prepare required documentation site plan showing boundaries existing buildings proposed work with accurate dimensions, floor plans existing and proposed layouts with room dimensions and uses, elevations all sides showing heights materials colors, engineering details if structural work, BASIX certificate if residential extension over 50sqm in NSW, lodgement submit application with all documents and pay fee, certifier assessment reviews compliance with all prescriptive standards no discretion for variations, determination issued typically 10-20 days private certifier 2-4 weeks or council 6-8 weeks, commencement notify certifier minimum 2 days before starting work, inspections mandatory inspections during construction footing inspection before concrete pour, frame inspection before covering structural elements, waterproofing inspection before tiling wet areas, final inspection before occupation, occupation certificate issued upon satisfactory final inspection for habitable works.

Exempt Development No Approval Required Internal Cosmetic Work: Exempt development category allows certain minor low-impact work to proceed without development approval or construction certificate, significantly reducing costs and delays for routine maintenance and internal renovations, however all exempt work must still comply with Building Code of Australia and relevant Australian Standards, licensed trades required for plumbing electrical and waterproofing work despite exemption from approval, exemptions vary by state and council with some councils having more restrictive local policies. Commonly exempt renovations Australia-wide: internal painting and decorating walls ceilings no approval required, floor covering replacement carpet timber floating floors tiles on existing substrate without structural changes, kitchen renovation existing layout replacing cabinets benchtops appliances without relocating plumbing or removing walls, bathroom renovation existing layout replacing tiles vanity toilet shower bath without relocating fixtures or removing walls, window and door replacement like-for-like same size and location maintaining existing openings, repairs and maintenance fixing existing elements like repairing roof tiles replacing gutters fixing cracks, air conditioning installation wall-mounted units under certain capacity typically under 3.5kW outside noise limits below 5dB above background, hot water heater replacement like-for-like same location capacity and fuel type, insulation installation ceiling or wall insulation without structural changes. Exempt development important conditions and limitations: Building Code compliance mandatory all exempt work must meet BCA standards particularly structural waterproofing fire safety requirements, licensed trades required plumbers licensed for all plumbing and drainage work electricians licensed for all electrical work average homeowner cannot DIY these trades, waterproofing certification required for all bathroom renovations must engage licensed waterproofer who provides compliance certificate to Australian Standard AS3740, no structural changes exempt status void if removing or altering load-bearing walls lintels beams columns, no external changes exempt development limited to internal work any external alteration typically requires approval, heritage properties exemptions do not apply to heritage listed buildings or buildings in heritage conservation areas where almost all work requires DA, strata properties strata approval may be required even for exempt development check strata bylaws, plumbing drainage relocation moving plumbing fixtures to different locations requires approval even if internal work. State-specific exempt development variations: NSW generous exemptions most internal work exempt under State Environmental Planning Policy (Exempt and Complying Development Codes) 2008, decks under 10sqm and under 1m high exempt, VIC strict regulations many renovations requiring planning permit particularly in overlays heritage neighborhood character, internal work generally exempt but varies significantly by overlay, QLD accepted development exempt or self-assessable categories depending on work, building approval required for most structural work even if planning approval exempt, WA R-Codes determine exemptions relatively generous for internal work, deemed-to-comply provisions for standard residential work, SA Development Plan codes vary significantly by council, many councils require approval for work NSW would consider exempt, TAS planning scheme codes vary by council, generally more restrictive than NSW with smaller exemption thresholds. Exempt development verification process: contact council planning department describe proposed work in detail and ask specifically if exempt approval required, provide property address as exemptions vary by zone and overlays affecting specific properties, request written confirmation email or letter stating work is exempt provides protection if council later disputes exemption status, check for heritage overlay flood zone bushfire zone environmental overlays on council maps online as these remove exemptions, engage private certifier for preliminary assessment fee $150-$300 provides professional opinion on exemption status reducing risk. Common mistakes assuming exemption: bathroom renovation relocating toilet or shower requires CDC or DA not exempt due to plumbing drainage relocation and wet area waterproofing certification, kitchen renovation removing wall even non-structural requires approval in some states for internal alterations assessment, deck or patio over 10sqm or over 1m high requires CDC even if small area once exceeds thresholds, airconditioning unit large capacity over 3.5kW or ducted systems typically require approval, roof replacement changing roof material or color may require approval particularly heritage areas, painting exterior often requires approval in heritage conservation areas or for heritage listed buildings. Exempt work still requires compliance documentation: plumbing compliance certificate from licensed plumber for all plumbing work stating work complies with Plumbing Code Australia, electrical compliance certificate Certificate of Electrical Safety from licensed electrician for all electrical work, waterproofing certificate from licensed waterproofer for bathroom laundry wet area work to AS3740 standard, retain all certificates as required for property sale conveyancer will request compliance documentation, some councils require notification of exempt work submit notification form though approval not required provides council record.

Council Approval Costs Timeline by Australian State 2026 Detailed Breakdown: Development approval costs and processing times vary significantly between Australian states due to different regulatory frameworks, fee structures, and council efficiency, understanding state-specific requirements and costs essential for renovation budgeting and timeline planning. Private certifier option available most states for CDC/building approval providing faster processing 2-4 weeks versus council 6-8 weeks at similar cost.

New South Wales (NSW) Approval Costs and Timeline: NSW uses two-tier system Development Application (DA) for planning approval and Construction Certificate (CC) for building approval, Complying Development Certificate (CDC) combines both approvals for eligible standard work. CDC costs NSW $1,500-$3,500 via private certifier including application assessment determination and first inspection, council CDC fees similar range though processing slower, timeline private certifier 10-20 days typical turnaround, council CDC 6-8 weeks, CDC covers carports garages decks internal alterations extensions under 40sqm pools granny flats under 60sqm meeting all SEPP standards. DA costs NSW $2,000-$6,000+ for residential alterations calculated on estimated cost of works typically 0.5-1% of project value, major projects over $500,000 can exceed $10,000 DA fees, timeline standard DA 8-16 weeks from lodgement to determination, complex DA with objections or heritage considerations 12-20+ weeks, DA required for second storey additions large extensions over 40sqm heritage property work significant external changes. Construction Certificate (CC) separate to DA costs $1,000-$2,500 council or $1,500-$3,500 private certifier, required after DA approval before commencing construction, shows detailed construction plans compliance with Building Code Australia, includes appointment of Principal Certifying Authority (PCA) for mandatory inspections. NSW specific requirements BASIX certificate required for residential alterations additions over 50sqm costs $150-$300 shows compliance with energy efficiency water efficiency targets, Long Service Levy payment 0.35% of project value over $25,000, section 68 approval for stormwater drainage connection separate from DA typically $200-$500. NSW key benefits generous exempt and complying development provisions allowing many standard renovations via fast-track CDC pathway, competitive private certifier market providing choice and faster service, online planning portal for most councils allowing digital lodgement tracking.

Victoria (VIC) Approval Costs and Timeline: VIC separate planning permit and building permit system, planning permit required if planning controls triggered by renovation, building permit required for almost all building work including many renovations NSW would consider exempt. Planning permit costs VIC $1,800-$5,000+ depending on council and application category, basic residential alterations $1,800-$2,500 typical, complex applications large extensions second storey $3,000-$5,000+, heritage overlay applications $3,500-$7,000+ due to additional assessment requirements, timeline standard planning permit 8-12 weeks, complex applications 12-20 weeks, VicSmart category for eligible minor works 10 business days statutory timeline fast-track for small additions sheds verandahs. Building permit costs VIC $1,200-$3,000 via private building surveyor (PBS) most common pathway as faster than council, includes plan assessment inspections mandatory reporting, timeline 2-3 weeks typical for standard residential work, council building permit similar cost but slower processing 4-6 weeks. VIC specific requirements planning permit triggered by many overlays including heritage overlay requiring permit for external changes and some internal structural changes, neighborhood character overlay requiring permit for extensions alterations affecting character, significant landscape overlay requiring permit for vegetation removal, design and development overlay with specific design requirements, vegetation protection overlay requiring permit for tree removal, bushfire management overlay requiring bushfire attack level assessment. VIC ResCode standards deemed-to-satisfy provisions for standard residential development, if proposal meets all ResCode standards planning approval more straightforward, variations from ResCode require design response demonstrating acceptable outcomes. VIC considerations planning permit requirements strict compared to other states, many renovations requiring permit in VIC would be exempt or CDC in NSW, private building surveyor recommended for faster building permit processing though cost similar to council, combined planning and building permit costs $3,000-$8,000 typical for extension requiring both approvals.

Queensland (QLD) Approval Costs and Timeline: QLD uses planning scheme codes and building approval framework, accepted development exempt or self-assessable under planning scheme codes, assessable development requires council approval. Building approval costs QLD $1,500-$3,200 via private certifier most common pathway for building work, includes plan assessment inspections certification, timeline 2-4 weeks typical, council building approval similar cost but slower 6-10 weeks. Development permit (planning approval) costs QLD $2,500-$7,000+ depending on council and application type, impact assessable development requiring public notification higher fees $4,000-$7,000+, code assessable development lower fees $2,500-$4,000, timeline code assessable 10-15 weeks, impact assessable 15-25 weeks including notification period and objection consideration. QLD specific framework accepted development complies with all applicable codes exempt from approval or self-assessable with building approval only, includes minor building work internal fit-outs some outbuildings, code assessable development complies with some but not all codes requires council assessment against relevant codes no public notification, impact assessable development does not comply with codes or triggers impact assessment requires full council assessment public notification potential for objections. QLD certifier role private certifier can assess building work and some operational work significantly faster than council, certifier cannot assess planning matters requiring development permit, building approval separate from development permit requiring both for most extensions alterations. QLD considerations granny flats secondary dwellings streamlined approval under state planning policy up to 60sqm, pool approval requires both pool safety compliance certificate and building approval if pool structure over certain specifications, bushfire areas planning approval requires bushfire hazard assessment building approval requires construction to bushfire attack level standards. QLD cost breakdown typical extension requiring both development permit and building approval: development permit $3,000-$5,000 council fees, building approval $1,800-$3,200 private certifier, professional fees plans $2,000-$5,000, total $6,800-$13,200 before construction.

Western Australia (WA), South Australia (SA), Tasmania (TAS) Approval Details: WA approval system building permit for construction development approval for planning if triggered by R-Codes or local planning scheme, building permit costs $1,000-$2,800 via private building surveyor or local government, timeline 2-4 weeks, development approval costs $2,000-$5,000+ if required, timeline 8-14 weeks, WA R-Codes residential design codes set deemed-to-comply standards for setbacks plot ratio building height, complying with R-Codes allows building permit only without development approval for many renovations, WA considerations generous setback provisions in R-Codes allowing larger structures closer to boundaries than eastern states, private building surveyors competitive market providing good service. SA approval system building approval for construction planning consent for planning matters, building approval costs $1,200-$2,500 via private certifier or council, timeline 2-3 weeks, planning consent costs $1,800-$4,500+ if required, timeline 8-12 weeks, SA Development Plan codes deemed-to-satisfy provisions if proposal meets all DTS criteria planning consent straightforward, performance assessed pathway if variations from DTS requires demonstrated compliance with performance outcomes. TAS approval system building permit for construction planning permit if required under planning scheme, building permit costs $1,000-$2,200, timeline 2-4 weeks, planning permit costs $1,500-$4,000+, timeline 8-14 weeks, TAS planning schemes vary significantly between councils, some councils strict planning requirements others more permissive, generally smaller exemption thresholds than mainland states requiring approval for smaller alterations extensions.

Development Approval Application Process Five Essential Steps: Successful council approval application requires careful preparation, complete documentation, and understanding of assessment criteria, following systematic process prevents delays, additional information requests extending timeline 2-6 weeks, and refusals requiring resubmission or appeals.

Step 1 Confirm Approval Type Needed Preliminary Assessment: Contact local council planning department via phone or visit planning counter describing proposed renovation work in detail, provide property address as approval requirements vary by zoning residential business industrial and overlays heritage character environmental affecting specific properties, request preliminary assessment whether work is exempt development requiring no approval, complying development eligible for CDC fast-track approval, or requires full Development Application. Check council online tools many councils provide online planning tools allowing property address search showing zoning overlays development controls applicable to specific property, zoning maps show land use zones R1 general residential R2 low density residential B1 neighborhood centre determining base development controls, overlay maps show additional controls heritage conservation overlay HCA, heritage item I, bushfire prone land, flood planning area, acid sulfate soils, coastal zone, environmentally sensitive areas ESA requiring additional assessment and documentation. Heritage overlay check critical heritage listings dramatically increase approval complexity cost timeline, heritage item I individual heritage listed building requires heritage impact statement from conservation architect demonstrating heritage significance preserved $2,000-$5,000+, heritage conservation area HCA contributory building requires heritage assessment showing proposed work consistent with conservation area character $1,500-$3,000, heritage approvals typically require 12-20+ weeks versus 8-12 weeks standard DA. Flood zone bushfire zone environmental zone checks properties in flood planning areas require hydraulic engineer flood impact assessment showing proposed development does not increase flood risk or flooding of other properties $2,000-$5,000+, bushfire prone land requires bushfire attack level BAL assessment and construction to BAL standards increasing construction costs 10-30% depending on BAL rating, environmentally sensitive areas may require ecological assessment threatened species survey additional environmental controls. Request written confirmation of approval pathway email or letter from council planning officer stating work is exempt or eligible for CDC provides protection if council later changes position, costs nothing to obtain preliminary assessment most councils provide free pre-lodgement advice, saves significant money avoiding preparation of full DA application when CDC or exempt pathway available.

Step 2 Engage Professionals Architects Engineers Certifiers: Professional team selection critical for approval success, experienced professionals understand council requirements, prepare compliant documentation, and navigate assessment process efficiently. For CDC applications engage building designer or draftsperson costs $800-$1,500 for simple carport garage deck plans showing site plan floor plan elevations with dimensions compliant with all SEPP or code requirements, private certifier costs $1,500-$3,500 total including plan preparation if required assessment determination and initial inspections, many certifiers provide package including both plan preparation and certification streamlining process, private certifier advantages faster processing 2-4 weeks versus council 6-8 weeks, flexible inspection times including early morning or late afternoon accommodating builder schedules, single point of contact throughout project, expert advice on compliance requirements. For DA applications engage architect or designer costs $3,000-$10,000 for small to medium residential extension second storey addition depending on complexity, architect provides conceptual design detailed plans elevations site analysis, statement of environmental effects SOEE describing proposal and addressing council assessment criteria, BASIX certificate energy water efficiency compliance for NSW extensions over 50sqm, coordination with other consultants structural engineer surveyor. Additional consultants for DA structural engineer required for second storey additions major structural alterations removing load-bearing walls costs $1,500-$3,500 provides engineering plans structural calculations certification, surveyor required if no recent survey available costs $800-$1,500 provides site survey showing boundaries levels existing structures easements, hydraulic engineer for stormwater management costs $1,200-$2,500 provides stormwater drainage plan showing runoff calculations detention requirements, heritage consultant for heritage properties costs $2,000-$5,000 provides heritage impact assessment statement, arborist if significant tree removal required costs $800-$1,500 provides arboricultural impact assessment. Professional selection criteria check qualifications architect registered with state board Architects Registration Board, building designer member Building Designers Association Australia BDAA, request portfolio of similar projects particularly projects in same council area demonstrating understanding of local requirements, check references contact previous clients about experience timeline budget compliance, compare quotes obtain 2-3 quotes for professional fees ensuring scope of work clearly defined avoiding variations later, clarify what is included some architects include all consultant coordination in fee others charge separately.

Step 3 Prepare Required Documentation Plans Reports Certificates: Complete accurate documentation essential for timely approval, incomplete applications returned to applicant or placed on hold until information provided extending timeline 2-6 weeks, all plans must be to scale typically 1:100 or 1:200 drawn by professional using CAD software showing accurate dimensions. Mandatory documentation all applications site plan showing property boundaries from survey or certificate of title, existing buildings structures with setbacks from boundaries, proposed new work location and setbacks, north point for solar access analysis, levels contours showing slope and drainage, easements rights of way affecting property, driveway access points, significant trees vegetation, adjoining properties buildings relevant to assessment. Floor plans existing and proposed showing all rooms with dimensions and areas, room names and uses, door and window locations with sizes, wall construction load-bearing walls clearly marked, ceiling heights, stairs and access if multi-storey, wet areas bathrooms laundry showing waterproofing, comparison between existing and proposed layouts clearly showing what is being altered. Elevations all four sides north south east west showing existing and proposed appearance, building heights measured from ground level to ridge or parapet, materials and finishes brick render timber Colorbond with colors specified, window and door sizes and types, roof pitch and material, relationship to adjoining properties particularly regarding overlooking, shadow diagrams if required showing overshadowing of adjoining properties at 9am 12pm 3pm on June 21 winter solstice critical for second storey additions. Additional documentation DA applications BASIX certificate NSW for alterations over 50sqm showing compliance with energy efficiency targets and water efficiency targets generated through NSW Planning Portal online tool, statement of environmental effects written report addressing council assessment criteria explaining how proposal complies with planning controls, addressing likely impacts traffic noise visual privacy solar access, demonstrating proposal consistent with zone objectives and character of area, 1-3 pages for simple alterations 5-10 pages for complex second storey additions. Structural documentation if structural work removing load-bearing walls structural opening additions building new second storey structural engineer provides structural plans showing beam sizes structural posts footings, structural calculations demonstrating structural adequacy load bearing capacity, engineer certification statement signed by engineer. Specialist reports heritage properties heritage impact statement describing heritage significance of building, assessing impact of proposed work on heritage significance, demonstrating sympathetic design respecting heritage character, includes historical research photographs analysis, flood affected properties hydraulic engineer report showing flood levels, demonstrating proposed work does not increase flood risk to property or adjoining properties, may require detention tank or permeable paving, bushfire areas bushfire attack level BAL assessment by accredited bushfire assessor, construction details showing compliance with BAL standards bushfire shutters ember guards non-combustible materials.

Step 4 Lodge Application Pay Fees Track Progress: Application lodgement process varies by council and approval type, CDC applications typically lodged with private certifier directly, DA applications lodged with council via online portal or in person at council chambers. CDC lodgement via private certifier make appointment with chosen certifier to review plans and eligibility, provide all required documents plans site plan floor plans elevations specifications, pay certifier fee $1,500-$3,500 typically 50% upfront 50% on determination, certifier conducts assessment typically 7-14 days reviewing compliance with all prescriptive standards, determination issued as CDC or refusal if non-compliant, commencement can occur immediately after CDC issued subject to 2 days notice to certifier. DA lodgement via council online portal create account on council planning portal most councils now accept online lodgements, upload all required documents PDF format plans reports certificates, complete online application form including applicant details owner consent property description works description estimated cost, pay council DA fee online calculated on estimated construction cost, receive application number for tracking, council validates application within 5-7 days checking all required information provided, council may request additional information RFI if documentation incomplete must respond within 14 days or application lapses. DA assessment process council planner assigned to application conducts site inspection viewing property from street and sometimes requesting access for internal inspection, planner assesses compliance with planning controls zoning provisions setbacks height FSR, assessment of environmental impacts privacy overlooking solar access visual impact streetscape, referral to internal departments if required traffic engineer heritage adviser urban designer tree management, public notification if required notice placed on property and letters sent to adjoining neighbors allowing 14-21 days for submissions objections, applicant may be requested to respond to submissions addressing concerns raised by neighbors, planner prepares assessment report with recommendation approval with conditions or refusal, determination issued approved with conditions typically requiring satisfaction of conditions before Construction Certificate, refused with reasons for refusal allowing applicant to appeal or submit modified application. Tracking application progress most councils provide online tracking showing application status received under assessment referred for notification determination, typical milestones lodgement day 0, validation day 3-7, assessment commences day 7-14, notification if required day 14-35, determination day 40-90 depending on complexity, contact council planner directly if no update for 2+ weeks checking progress and whether additional information required.

Step 5 Approval Issued Satisfy Conditions Construction Certificate: DA or CDC approval issued with conditions that must be satisfied before commencing work, conditions of consent typical requirements pay Section 94 contribution infrastructure levy if applicable, obtain Construction Certificate from council or certifier, submit detailed stormwater drainage plans, arrange dilapidation report for adjoining properties if excavation within 3m of boundary, provide Long Service Levy payment proof, submit builder details and insurance, appoint Principal Certifying Authority PCA for inspections, submit engineering details structural plans calculations. Construction Certificate required after DA approval before commencing building work, shows detailed construction plans complying with Building Code Australia BCA including structural details waterproofing details fire safety measures if required, obtained from council $1,000-$2,500 or private certifier $1,500-$3,500, private certifier faster 1-2 weeks versus council 3-4 weeks, submit architectural plans with construction details, structural engineer plans if structural work, specification of materials, energy efficiency measures BASIX compliance, access compliance if required. CDC combines development approval and construction approval single certificate, can commence work immediately after CDC issued subject to 2 days notice to PCA, no separate Construction Certificate required. Commencement requirements notify PCA minimum 2 days before commencing work providing Notice of Commencement, appoint PCA if not already appointed typically the certifier who issued Construction Certificate or CDC, arrange mandatory inspections with PCA footing inspection before concrete pour, frame inspection before covering structural elements including walls roof framing, waterproofing inspection before tiling wet areas bathrooms laundry, stormwater drainage inspection before backfilling, final inspection before occupation. Builder requirements ensure builder licensed in relevant state NSW contractor license VIC building practitioner registration QLD QBCC license, verify Home Warranty Insurance provided by builder for contracts over $20,000 most states, check public liability insurance and workers compensation insurance current, signed contract specifying scope of works price timeline payment schedule, do not pay more than 10% deposit upfront avoid paying significant progress payments ahead of work completed. Occupation Certificate or Certificate of Final Inspection issued by PCA after satisfactory final inspection, required before occupying new habitable rooms extensions, certifies work complies with development consent and Construction Certificate, required for property sale conveyancer will request as evidence of approved compliant work, keep all approval documents safe DA approval Construction Certificate CDC Occupation Certificate compliance certificates plumbing electrical waterproofing for property records and future sale.

Penalties for Renovating Without Required Council Approval Australia 2026: Working without council approval when required illegal under state environmental planning legislation, councils have extensive enforcement powers including fines $5,000-$800,000, stop work orders halting construction, demolition orders requiring removal of non-compliant work at owner expense, prosecution in court for serious breaches, penalties and consequences severe and remediation costs typically far exceed original approval costs.

Immediate Penalties Fines and Stop Work Orders: Fines for unapproved development vary significantly by state reflecting different regulatory frameworks and penalty regimes, NSW individuals $5,000-$110,000 for breaches of Environmental Planning and Assessment Act, corporations $110,000-$1.1 million for serious breaches, daily penalties apply for continuing breaches after stop work order $11,000 per day, VIC individuals $16,000-$312,000 under Planning and Environment Act, on-the-spot fines $1,000-$5,000 for minor breaches, court-imposed fines for serious breaches including unauthorized demolition heritage buildings, QLD individuals $40,000-$800,000 highest penalties Australia reflecting strict enforcement regime, corporations $4 million maximum penalty for serious environmental harm, daily penalties for continuing breaches, WA individuals $50,000-$200,000 under Planning and Development Act, daily penalties for ongoing breaches after notice, SA individuals $15,000-$120,000 under Development Act, court can impose higher penalties for repeat offenders or commercial developments. Stop work orders issued immediately when unapproved work discovered by council, council officers conduct routine inspections responding to neighbor complaints or observing works from street, stop work order requires immediate cessation of all building work, builders must leave site immediately materials equipment left exposed to weather, temporary protection allowed but no further construction permitted, penalties for continuing work after stop work order $5,000-$50,000 plus contempt of court if court order, stop work order remains in place until council satisfied either work is approved retrospectively or unauthorized work removed, resuming work without approval resolution can result in court injunction and additional penalties. Demolition orders council can order removal of unauthorized structures that cannot be approved retrospectively, demolition order issued if work does not comply with planning controls setbacks height FSR, if work in heritage area without approval causing heritage harm, if work creates safety hazards or amenity impacts to neighbors, if retrospective DA refused by council, owner must demolish work at own expense typically $10,000-$100,000+ depending on extent of unauthorized work, failure to comply with demolition order within specified timeframe allows council to demolish and recover costs from owner with additional administrative fees and legal costs, courts can impose additional penalties for non-compliance with demolition orders $20,000-$200,000+.

Long-Term Consequences Property Sale Insurance Valuation: Cannot sell property with undisclosed unapproved work section 10.7 planning certificate section 149 certificate issued by council shows all approved development and any enforcement actions or compliance orders on property, vendor must disclose all unapproved work to purchaser in contract of sale, failure to disclose allows purchaser to rescind contract and sue for misleading conduct, purchaser building and pest inspection typically identifies unauthorized work structural changes external additions, conveyancer solicitor obtains planning certificate showing no approval for recent works raising red flag, purchaser either withdraws from contract, demands price reduction $30,000-$100,000+ reflecting cost of retrospective approval or removal, requires vendor to obtain retrospective approval before settlement extending settlement 6-12 months, property effectively unsaleable until approval obtained or work removed, real estate agents required to disclose known unapproved work to prospective purchasers creating disclosure obligations. Insurance void or claims rejected home insurance policies exclude cover for damage related to unapproved structural alterations, if unapproved extension causes water damage to rest of home insurer may deny entire claim not just extension damage, public liability insurance void if injury occurs on property due to defective unapproved work, owner personally liable for injuries to tradesperson visitors neighbors potentially $100,000-$1 million+ compensation, mortgage lenders can demand immediate repayment if discover unapproved work breaching loan terms, property valuation reduced bank valuation excludes value of unapproved structures when refinancing or extending mortgage, or requires removal or approval before approving mortgage variation. Bank financing issues prospective purchasers cannot obtain mortgage finance for property with unapproved work, banks require all structures shown on valuation to have council approval, require section 10.7 planning certificate showing no enforcement actions or orders, effectively limits buyer pool to cash buyers reducing sale price 20-40%, banks may approve mortgage conditional on rectification requiring either retrospective approval or demolition before settlement proceeds, lenders mortgage insurance LMI providers refuse to insure properties with unapproved work increasing deposit requirement to 20%+.

Retrospective Approval Options Costs and Risks: Retrospective Development Application can be submitted for unauthorized work already completed, however significantly more expensive risky uncertain than obtaining approval before commencing work, many councils have policies refusing retrospective DAs particularly for flagrant breaches or works causing amenity impacts. Retrospective DA costs 2-3 times normal approval costs council fees higher for retrospective applications in some councils penalty loading applied, professional fees higher architect must justify existing work rather than design optimal compliant proposal costs $5,000-$15,000 versus $3,000-$10,000 for standard DA, additional reports required independent structural engineer certification that existing work structurally sound, building certifier assessment of BCA compliance potentially requiring extensive rectification, total costs $8,000-$25,000+ retrospective approval versus $4,000-$12,000 standard DA for equivalent work. Retrospective DA assessment process council takes harder line on retrospective applications, less flexibility on variations from planning controls that might be acceptable in standard DA, neighbor objections given significant weight particularly if neighbors previously complained about unauthorized work, council may require modifications to existing work adding windows for overlooking compliance, increasing setback by partially demolishing structure reducing size, changing materials or colors to match heritage character, modification requirements can cost $10,000-$50,000 additional demolition partial rebuilding. Retrospective DA refusal risk higher than standard DA council can refuse retrospective DA if work non-compliant, refusal triggers demolition order requiring removal at owner expense, appeals possible to Land and Environment Court but expensive $15,000-$50,000 legal costs, court can uphold refusal requiring demolition or impose conditions, no guarantee of approval owner may spend $15,000-$25,000 on retrospective DA and still face demolition order. Timeline retrospective DA process 6-12+ months from lodgement to resolution, during this period property cannot be sold, additional stress and holding costs mortgage interest rates utilities insurance, if retrospective DA refused and demolition ordered additional 3-6 months to demolish and restore property. Fines still apply retrospective DA does not void penalties for illegal work, council can prosecute for past breach and impose fines even if retrospective approval ultimately granted, some councils waive fines if retrospective approval obtained others pursue both approval and penalties particularly flagrant breaches.

Professional Licensing Insurance Requirements Australia Renovations 2026: All building work in Australia must be performed by appropriately licensed contractors, licensing protects consumers through competency requirements insurance mandates statutory warranties, using unlicensed contractors illegal and voids warranties insurance creates owner liability, licensing thresholds and requirements vary by state.

Builder Licensing Requirements by State: NSW contractor license required for all residential building work over $5,000 or structural work any value issued by NSW Fair Trading, builder must hold supervisor certificate or qualified supervisor certificate demonstrating technical qualifications experience, specialist licenses for plumbing drainage gas fitting electrical work waterproofing, check license current via NSW Fair Trading website license number should appear on quotes and contracts, VIC building practitioner registration required for all building work over $10,000 or structural work registered with Victorian Building Authority VBA, domestic builder registration unlimited for any value or limited registration for work under $16,000, specialist registrations for plumbing electrical demolition, check registration via VBA website registration number on contracts, QLD Queensland Building and Construction Commission QBCC license mandatory for all building work over $3,300, builder must hold contractor license appropriate category residential construction renovations, specialist licenses for plumbing drainage gas fitting electrical, check license via QBCC website license should appear on quotes and contracts, WA building services registration for residential building work over $20,000 registered with Building Services Board, plumbing and electrical licenses separate requirements, SA building work contractor license for work over $12,000 registered with Consumer and Business Services, specialist licenses for plumbing drainage electrical work.

Essential compliance information: When Council Approval Required: Structural changes (removing/adding walls, floor/ceiling modifications), building extensions (second storey, room additions, garages), outdoor structures (decks, pergolas, carports, sheds over size limits), plumbing/drainage changes, electrical work (switchboard upgrades, new circuits), bathroom/kitchen relocations, demolition work, heritage-listed properties (any external changes), changes to building footprint/envelope. When Council Approval NOT Required (Exempt Works): Internal cosmetic renovations (painting, flooring, tiling), kitchen renovation without plumbing changes, bathroom renovation without layout changes, minor repairs/maintenance, replacing like-for-like (doors, windows same size), small sheds under 10sqm, low-height decks under 1m height, fencing within height limits, air conditioning installation (wall/window units), solar panel installation on existing roof (some areas). Development Application (DA) Process: Step 1 Pre-DA consultation with council ($0-$200). Step 2 Engage architect/draftsperson for plans ($1,500-$5,000). Step 3 Submit DA with plans, site plans, specifications ($500-$3,000 application fee). Step 4 Public notification period 14-21 days (neighbors can object). Step 5 Council assessment 30-90 days. Step 6 Approval granted with conditions OR refusal with reasons. Total timeline 6-16 weeks from submission to decision. Complying Development Certificate (CDC): Fast-track approval for pre-approved designs meeting specific criteria. Processed by private certifiers, not council. Faster approval 10-20 days vs 30-90 days for DA. Lower cost $800-$2,000 vs $2,000-$5,000 for DA. No neighbor notification required. Available for common renovations (minor extensions, decks, carports, granny flats). Not available in heritage areas or for non-standard designs. About 60% of residential work qualifies for CDC vs DA. Application Costs by State: NSW DA $1,500-$4,000, CDC $800-$2,000. VIC building permit $800-$2,500. QLD DA $1,000-$3,500. WA DA $1,200-$3,000. SA DA $800-$2,500. Costs vary by project value and council. Small renovations under $50K typically $800-$1,500. Medium renovations $50K-$200K typically $1,500-$3,500. Large renovations over $200K typically $3,000-$6,000+. Required Documentation: Architectural plans showing existing and proposed layouts, elevations, dimensions. Site plan showing property boundaries, setbacks, easements, neighboring properties. Engineering drawings for structural work. Energy efficiency compliance (6-star rating). Waste management plan. Stormwater drainage plan. BAL (Bushfire Attack Level) assessment if in bushfire zone. Arborist report if removing protected trees. Heritage impact statement if in heritage area. Construction Certificate (CC): Required after DA/CDC approval before starting work. Issued by council or private certifier. Verifies plans meet Building Code of Australia. Cost $500-$1,500. Includes mandatory inspections during construction (footing, frame, waterproofing, final). Must be obtained within 12 months of DA approval or approval lapses. Cannot start construction without valid CC. State-Specific Requirements: NSW requires Owner Builder Permit if doing own work over $5,000. VIC requires building permit for all structural work. QLD requires pool safety certificate for any pool work. WA requires bushfire compliance in mapped areas. SA requires development approval even for some internal work. Check specific council requirements as they vary even within states. Timeline Expectations: Pre-DA consultation 1-2 weeks. Plan preparation by professional 2-6 weeks. DA submission to approval 6-16 weeks (simple projects 6-8 weeks, complex 12-16 weeks). CDC submission to approval 10-20 days. CC application to approval 1-2 weeks. Total from concept to construction start: DA route 10-24 weeks, CDC route 6-10 weeks. Penalties for Unapproved Work: Fines $3,000-$110,000 depending on state and severity. Council orders to demolish unapproved structures. Cannot sell property without rectification. Building insurance may be void. Mortgage/refinance issues (banks require compliance). Neighbor complaints can trigger council investigation. Retrospective approval possible but not guaranteed and often costs more. Legal liability if defects cause injury/damage. Neighbor Objections: For DA applications, neighbors notified and can object during 14-21 day period. Common objection grounds: Overshadowing of neighboring property, privacy concerns (overlooking), loss of views, noise/disruption during construction, non-compliance with setbacks, out of character with neighborhood, increased traffic/parking issues. Council must consider objections but doesn't automatically refuse. Address concerns in application (e.g., privacy screens, setback compliance, construction management plan). Professional Help Required: Architect or draftsperson for plans $1,500-$8,000. Structural engineer for load-bearing work $800-$3,000. Private certifier for CDC/CC $1,500-$4,000. Town planner for complex DAs $2,000-$8,000. Energy assessor for NatHERS rating $150-$400. Surveyor for site plans $500-$2,000. Building consultant for pre-purchase advice $300-$800. Heritage Properties Additional Requirements: Any external changes require heritage approval. Heritage Impact Statement required $1,500-$5,000. Must use sympathetic materials matching original. Cannot alter significant features. Longer approval times 12-24 weeks. Some internal work also requires approval. Heritage consultant recommended $2,000-$5,000. Higher rejection rate than standard properties. Conservation architect often required. Common DA Refusal Reasons: Non-compliance with setback requirements. Overshadowing of neighboring properties exceeding limits. Insufficient parking provision. Inadequate stormwater management. Non-compliance with heritage controls. Excessive site coverage or floor space ratio. Unresolved neighbor objections on valid grounds. Missing required documentation. Design not in keeping with local character. Solutions: Modify design to address concerns, provide additional documentation, engage town planner to argue case, appeal to local planning panel or Land and Environment Court (costly $5,000-$30,000+). Modifications to Approved Plans: Minor changes (materials, internal layout) usually don't require new approval. Significant changes (size, height, position) require modification application $500-$1,500. Must be approved before implementing changes. Working outside approved plans same penalties as unapproved work. Keep detailed records of all approvals and modifications. When to Engage Professionals: Complex projects (second storey, large extensions), heritage properties, previous DA refusals, significant neighbor objections, site constraints (bushfire, flood, steep slope), commercial/mixed-use developments, time-sensitive projects (use private certifier for speed), unfamiliar with planning rules. DIY DA possible for simple projects but professional input increases success rate from 70% to 95%.

Council Approval Requirements at a Glance 10 min read

Quick guide to DA, CDC, and exempt development

Most minor renovations don't require council approval, but any structural changes, additions over 10sqm, or external alterations typically need either a Development Application (DA) or Complying Development Certificate (CDC). Understanding which pathway applies to your project saves time and costly mistakes.

Exempt Development

No approval needed for internal renovations, painting, minor repairs

CDC/Complying Development

Fast track approval in 20 days for standard work ($1,500-$3,500)

DA/Development Approval

When to Get Help

Penalties $5,000-$800,000. Always get professional advice

Key Approval Tips:

Never start work before approval is issued. Starting renovations without required approval results in stop-work orders, fines up to $800,000, and potential demolition orders. Contact your council first to confirm which approval pathway applies to your project. When in doubt, always get professional advice from a private certifier or architect.

QLD: $1,500-$3,500 depending on council. WA/SA: $1,200-$3,000. Major projects over $500k can cost $5,000-$15,000+ in DA fees. Fees are non-refundable even if application refused.

How long does council approval take for renovations?

Council approval timelines vary by application type. Complying Development (CDC): 10-20 days in NSW for standard work meeting codes. Standard DA: 6-12 weeks for most residential renovations. Complex DA: 12-20 weeks for heritage areas, large projects, or applications requiring neighbour consultation. VicSmart (VIC): 10 days for eligible minor works. Public notification adds 14-21 days. Budget 8-16 weeks for typical renovation DA.

Do I need council approval for a bathroom renovation?

Complying Development Certificate (CDC) required for most bathroom renovations as they involve plumbing work, even if layout unchanged. Full DA required if: adding new bathroom, relocating bathroom to different room, structural changes to walls or floors, or heritage/character overlay on property. No approval needed for simple cosmetic updates (paint, tiles, fixtures) without plumbing relocation. Internal alterations without structural changes may be exempt in some councils - check local rules.

What is the difference between DA and CDC approval?

Development Application (DA) required for complex work not meeting standard codes - assessed case-by-case, costs $2,000-$5,000, takes 6-12 weeks, neighbour notification usually required. Complying Development Certificate (CDC) for straightforward work meeting prescriptive standards - faster approval (10-20 days), similar cost ($1,500-$3,000), no neighbour consultation, issued by private certifier or council. CDC available for: decks under 1m high, carports, internal alterations, some extensions. Not available in heritage areas or bushfire zones.
5

Can I start renovations while waiting for council approval?

No - you cannot start any physical work before approval issued. Starting work without approval results in: stop-work orders from council, fines $5,000-$50,000, requirement to demolish non-compliant work, difficulty selling property with illegal work, insurance may not cover unapproved work, and criminal charges for serious breaches. You can: obtain quotes, order materials, book tradies for post-approval start. Only demolition permits allow partial work (demolition only) before full approval.

How much does a private certifier cost vs council?

Private certifier costs $2,000-$4,500 for CDC applications, similar to council fees but faster service (10-20 days vs 6-8 weeks). For Construction Certificate and inspections, private certifiers charge $1,500-$3,500 depending on project size. Total project certification (CDC + CC + inspections) costs $3,500-$8,000. Benefits of private certifiers: faster processing, flexible inspection times, single point of contact, expert advice. Council may be cheaper for small projects but slower.

What renovations can I do without council approval?

Exempt development (no approval needed) includes: internal cosmetic work (painting, floor coverings, kitchen cupboards without structural changes), replacing like-for-like fixtures, minor repairs and maintenance, letterboxes and clotheslines, solar panels on existing roof (usually), and airconditioning units under certain size/noise limits. Approval always required for: structural changes, new rooms or extensions, plumbing/drainage alterations, external building changes, decks over 1m high, carports/garages, swimming pools, and heritage properties (almost all work).
8

When should I hire an architect for council approval?

Hire an architect or building designer when: project involves structural changes, extensions, or new rooms (DA required), heritage or character overlay applies (complex approval), project value exceeds $100k (design optimization saves money), non-standard design or complex site (slopes, easements), or council likely to refuse standard application. Architects cost $8,000-$25,000 but improve approval success rate and design quality. For simple work meeting CDC requirements, builder can prepare plans for $1,000-$3,000.

What happens if I renovate without council approval?

Renovating without approval leads to: immediate stop-work order when discovered, fines $5,000-$50,000 (individuals) or up to $1M (companies), requirement to lodge retrospective DA (often refused), demolition of non-compliant work at your expense ($10,000-$100,000+), inability to sell property without disclosure (reduces value 10-30%), insurance claims rejected for unapproved work, and difficulty refinancing mortgages. Council can prosecute up to 5 years after work completed. Always get approval first - penalties far exceed approval costs.
10

Is building insurance required during renovations?

Yes, Home Warranty Insurance (HWI) mandatory for residential building work over $20,000 in most states ($20k in NSW, VIC, QLD; $20k-$200k in WA depending on work type). Builder must provide HWI certificate before accepting deposit. HWI covers incomplete or defective work if builder dies, disappears, or becomes insolvent. Cost: 0.5-2% of contract value ($100-$4,000 on typical projects). Also maintain your home insurance during renovations - notify insurer of works to ensure coverage for construction-related damage.
