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.

Fast-track available

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.

Sydney: assessed by City of Sydney under the New South Wales rules below.

Approval pathway: The exempt development standards for fences sit in the General Exempt Development Code of State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 and are set by zone; separate complying development standards apply under the Housing Code. Meet every standard and no approval of any kind is required. Exceed a height, use masonry above 1.2 m, or build on a heritage item, in a conservation area or on environmentally sensitive land, and you need a Development Application to council. A pool barrier is separately regulated under the Swimming Pools Act 1992 regardless of planning approval.

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

Overlays can change your eligibility

Heritage and flood 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 Sydney

These are the overlays that can remove the fast-track, measured across every parcel in Sydney 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	82.12%	24,621 parcels flagged. The rest are mapped and sit outside it.
Flood	Not mapped	No flood mapping is published for Sydney, so it cannot be ruled out here. That is not the same as the land being clear.

The most common zone in Sydney is General Residential, covering 58.8% of its 29,981 parcels. What you can build is decided by your own lot's zone, not the council's most common one.

Measured from our mapped parcel data, snapshot taken 2026-09-06. Overlays are checked live for a specific address on the address tool.

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.

Which council approves a fence in Sydney?

City of Sydney is the consent authority for Sydney (Inner Sydney). You can review local planning controls on the council website and lodge through your state planning portal.

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

Up to 1.8 m above existing ground level behind the building line, and up to 1.2 m forward of the building line or in a road setback. Masonry is limited to 1.2 m anywhere.
