SA: Planning approval overview (development approval)
How planning fits into the SA pathway, what usually triggers it, and how to reduce redesign loops.
Tip: planning rules vary by site/zoning/overlays. Confirm requirements early with your council or planning portal before you lock in design.
In 60 seconds
- Planning is about what you’re allowed to build on the site (use, setbacks, height, character, heritage, etc.).
- Even if planning approval isn’t required, you may still need building approval.
- The fastest way to reduce delays is to confirm requirements for your address before design is final.
What commonly triggers planning
Site rules
- Zoning / land use rules
- Overlays (heritage, bushfire, flooding, etc.)
- Setbacks, height, site coverage
- Parking / access requirements
Project type
- New dwelling construction
- Extensions that change bulk/height/setbacks
- Changes in use (where applicable)
- Outbuildings, decks, verandahs (depending on site rules)
Common mistake
Designing first, then discovering an overlay forces a major redesign (or refusal). Do the “address check” early.
Practical steps (avoid the loop)
- Confirm whether planning/development approval is required for your address and scope.
- Ask what documents council expects (site plan, elevations, shadowing, stormwater, etc.).
- Get clarity on key constraints: setbacks/height/overlays and any neighbourhood character expectations.
- Only then finalise drawings for building approval.
