Fences rules in Adelaide
Building a fence 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.
Exempt from development approval up to 2.1 m
In South Australia a fence up to 2.1 m high is exempt from development approval, measured from the lower of the two adjoining finished ground levels. Masonry is the big exception - any part formed from masonry, including piers and columns, is only exempt to 1 m.
Key rules at a glance
| Max height (front setback) | 2.1 m applies generally, but no more than 1 m within 6 m of the intersection of two road-facing boundaries |
| Max height (side/rear) | 2.1 m, measured from the lower of the two adjoining finished ground levels |
| Masonry limit | 1 m - any part formed from masonry, including piers or columns, above 1 m needs development approval |
| Approval needed? | No development approval within those limits; otherwise a development application to council or a private certifier |
| Pool fence | Min 1.2 m, compliant with AS 1926.1 - a pool safety fence is never covered by the exemption and always needs approval |
| Dividing fence law | Fences Act 1975 |
| Who pays? | Neighbours are normally each liable for half the cost of a dividing fence, on the basis that both get equal benefit |
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.
