Sheds & Garages rules in Adelaide
Building a shed or garage in Adelaide? City of Adelaide applies the South Australia planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
No approval for outbuildings up to 15 m²
A detached outbuilding of 15 m² or less (10 m² in heritage/conservation zones), no more than 2.5 m high with no span over 3 m, is exempt development in most of SA — no planning or building approval. Bigger sheds need development approval.
Key rules at a glance
| Max floor area (exempt) | 15 m² (10 m² in Historic/Conservation zones) |
| Max height | 2.5 m above natural ground level |
| Max span | 3 m |
| Position on lot | Behind the building line to the primary street |
| Setback (corner sites) | ≥900 mm from a secondary-street boundary |
| Must be | Detached from, and ancillary to, an existing building on the site |
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.
How often this applies in Adelaide
These are the overlays that can remove the fast-track, measured across every parcel in Adelaide from the same data behind our zoning map. They describe the council, not your block, and they are counted separately — one parcel can carry more than one, so they cannot be added together.
| Overlay | Share of parcels | What that means here |
|---|---|---|
| Heritage | 50.19% | 6,530 parcels flagged. The rest are mapped and sit outside it. |
| Flood | 100% | 13,011 parcels flagged. The rest are mapped and sit outside it. |
| Bushfire | 0% | Mapped right across Adelaide, and no parcel is flagged. |
The most common zone in Adelaide is City Living, covering 51.6% of its 13,011 parcels. What you can build is decided by your own lot's zone, not the council's most common one.
