What council approvals do I need to build a house in Adelaide?

You need two approvals in SA: Planning Consent (does the design comply with the Planning and Design Code?) and Building Rules Consent (does the build comply with the National Construction Code?). Both are lodged through the PlanSA portal. Together they take 4-20 weeks depending on your council, overlays and design complexity. You also need a Certificate of Occupancy before you can move in.

Step 1 - Planning Consent

Assesses your proposed design against the Planning and Design Code plus your council's specific policies. Lodged through the PlanSA portal. Assessment time: 4-16 weeks depending on council and overlays. Complexity drivers: Character Area, Historic Area, Heritage Place listings, Bushfire Prone Area, Coastal Overlay, Regulated Tree, and Public Notification triggers.

Step 2 - Building Rules Consent

Assesses your design against the National Construction Code (formerly BCA). Focuses on structure, fire safety, energy efficiency, accessibility and health. Can be issued by council or a private certifier. Typical fee: $521 or 0.25% of build cost for a Class 1 dwelling. Assessment: 2-4 weeks once documents are complete.

Step 3 - Development Approval and construction

Development Approval = Planning Consent + Building Rules Consent + any conditions. Once issued, construction can commence. You must appoint a certifier (council or private) to inspect key stages: footings, slab, frame, wet area waterproofing, and final. Missing inspections voids the approval.

Step 4 - Certificate of Occupancy

Issued at the end of the build once the certifier confirms all inspections passed and the build matches the approved plans. You cannot legally occupy the dwelling until this cert is on file. Some builders arrange a 2-4 week "practical completion" window - you cannot move in during it.

Frequently asked

How long does council approval take in Adelaide?

Standard metro Class 1 dwelling: 4-8 weeks combined Planning + Building Rules Consent. Character or heritage overlay area (Prospect, Burnside, Charles Sturt inner suburbs, Norwood): 12-20 weeks. Bushfire-prone hills lot: add 2-4 weeks. See our per-council guides for accurate timelines.

What is Public Notification and does it apply to me?

Public Notification is when your neighbours get 15 business days to formally object to your development. Triggered for most dual-occupancy, subdivision, character-area builds, and any design that deviates from a policy. It adds 3-6 weeks and neighbour objections can force design changes.

Do I need council approval for a granny flat in Adelaide?

Yes. All granny flats in SA require Planning Consent + Building Rules Consent regardless of size. Since the 2023 rule change, granny flats can be rented separately from the main dwelling but the approval process is unchanged. Budget 6-12 weeks approval time.

What triggers a Statement of Heritage Impact?

Any development on a State Heritage Place, Local Heritage Place, or (often) a lot adjacent to a heritage-listed dwelling. Council may request one at RFI stage even without a formal listing. Cost: $1,500-$3,500 for an accredited heritage consultant. Add 3-6 weeks.
