Fences rules in New South Wales (2026)
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.
Usually no approval needed within the exempt heights

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 |
Conditions & eligibility
- The fence must not incorporate barbed wire or be electrified in a residential zone
- Metal components must be low-reflective, factory pre-coloured material
- On a sloping site a stepped fence must be no more than 2.2 m above existing ground level at each step
- The exemption does not apply on a heritage item, in a heritage conservation area, or on environmentally sensitive land
- To recover half the cost, serve a written fencing notice on your neighbour describing the work and the cost
- Your neighbour has 1 month to respond; after that either owner can go to a Community Justice Centre for mediation, or to the Local Court or NCAT
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 approval works in New South Wales
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.
Council DCPs commonly add front-fence design controls, corner-lot sightline splays and materials rules on top of the state exempt standards, so check your local DCP before building forward of the building line.

Frequently asked questions
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.
Does my neighbour have to pay half the fence in NSW?
Yes, for a 'sufficient dividing fence' the Dividing Fences Act 1991 makes adjoining owners liable in equal shares. If you want something better than sufficient - say sandstone instead of timber - you pay the difference.
What happens if my neighbour ignores my fencing notice?
After 1 month you can try free mediation at a Community Justice Centre, or apply to the Local Court or NCAT for an order about the work and the cost split.
