Fences rules in Sydney
Building a fence in Sydney? City of Sydney applies the New South Wales planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Usually no approval needed within the exempt heights
Most residential fences in NSW are exempt development under the Codes SEPP, so no DA or CDC is needed - up to 1.8 m behind the building line and 1.2 m in front of it. Masonry is capped at 1.2 m anywhere, and the exemption switches off on heritage items and in heritage conservation areas.
Key rules at a glance
| Max height (front setback) | 1.2 m above existing ground level forward of the building line, or in the setback to a primary or secondary road |
| Max height (side/rear) | 1.8 m above existing ground level behind the building line |
| Masonry limit | No masonry construction above 1.2 m - a taller brick or block fence needs a DA |
| Approval needed? | No DA or CDC if every exempt standard is met; a DA to council otherwise |
| Pool fence | Min 1.2 m, compliant with AS 1926.1; a boundary fence used as part of the barrier must be at least 1.8 m |
| Dividing fence law | Dividing Fences Act 1991 |
| Who pays? | Adjoining owners contribute equally to a 'sufficient dividing fence'; anything above that standard is at the requesting owner's cost |
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.

Frequently asked questions
Do I need council approval for a fence in Sydney?
Often not. New South Wales allows a fence to proceed without a full development application when it meets the standards, and City of Sydney follows that framework. But local overlays — heritage, flood or bushfire — can remove the fast-track, so check your exact address before you rely on it.

How high can a fence be in NSW without council approval?
