Do I always need council approval to build a fence in NSW?

Not always. Many standard boundary and dividing fences are treated as exempt development in NSW, meaning they generally do not need development approval provided they meet the height, location and material conditions set out in the relevant state planning policy and your council. Fences that exceed those conditions — for example, taller front fences, fences on heritage or bushfire-affected land, or fences near a road corner — typically do require approval. Because the rules vary, you should always confirm your specific situation with your local council before starting.

What fence height is usually allowed without approval in NSW?

As a general guide, side and rear boundary fences are commonly allowed up to a moderate height as exempt development, while front fences facing the street are usually limited to a lower height, and solid masonry front fences are typically restricted further. Exact figures differ between councils and depend on the zone, the street and whether the fence is solid or open. Rather than relying on a single number, check the current thresholds with your council, as they are the authority that applies them to your address.

Are the rules different for a dividing fence between neighbours?

Yes, a dividing fence involves two separate sets of rules. Planning approval covers whether the structure itself is permitted, while the Dividing Fences Act 1991 (administered with guidance from NSW Fair Trading) governs how neighbours share the cost and agree on a fence. A standard replacement dividing fence is often exempt from approval, but you generally still need to reach agreement with your neighbour on the type and cost. For cost-sharing disputes, NSW Fair Trading and the local court process apply.

When does a fence definitely need council approval?

A fence more commonly needs approval when it exceeds the exempt height limits, is a solid masonry or brick front fence above the allowed height, is on land that is heritage-listed, flood-prone, bushfire-prone or an environmentally sensitive area, is near a road intersection where sight lines matter, or forms part of a pool safety barrier subject to separate rules. These situations often require a development application or a complying development certificate. Your council or a private certifier can confirm which pathway applies.

Do pool fences have different approval rules?

Yes. Pool barriers are governed by separate swimming pool safety legislation in NSW, which sets strict requirements for height, gaps, gates and non-climbable zones, and requires registration and certification of the pool. A pool fence must meet these safety standards regardless of general fencing exemptions, and compliance is checked through inspection and certification rather than ordinary fence rules. Always treat pool fencing as a specialised, regulated barrier.

Do I Need Council Approval for a Fence in NSW? The General Picture

If you are asking "do I need council approval for a fence in NSW?", the honest answer is: it depends. Many everyday boundary and dividing fences are treated as exempt development, which generally means no development application is required — provided the fence stays within the height, location and material conditions set out in NSW planning rules and your local council's controls. Step outside those conditions and approval is usually needed.

The reason there is no simple yes-or-no answer is that the requirements combine state-wide planning policy with council-specific rules, and they change depending on your zone, the street, the fence height, the material and whether your land has any heritage, flood or bushfire overlays. A modest rear Colorbond fence and a tall solid brick front fence are treated very differently.

Below we set out the general rules that typically apply across NSW, so you know what to expect before you build. Use it as a starting point, not the final word — your council is the authority that applies the rules to your specific address.

Important: Please Confirm Before You Build

This page provides general information only and is not legal, planning or professional advice. Fencing rules in NSW vary by council, zone and property, and they can change. Before building, altering or replacing any fence, you should confirm the current requirements directly with your local council, and for matters about sharing costs with a neighbour, refer to NSW Fair Trading and the Dividing Fences Act. Jacob Landscaping and Fencing is a fencing contractor, not a planning or legal authority.

General NSW Fence Rules Summary

What typically applies — always verify the specifics with your council.

Often Exempt (Typically No DA)

Standard side and rear boundary fences within the allowed height
Like-for-like replacement of an existing dividing fence
Open-style front fences kept under the lower front-fence limit
Common materials such as timber, Colorbond and aluminium at compliant heights

Generally Needs Approval

Fences taller than the exempt height limits for their location
Solid masonry or brick front fences above the allowed height
Fences on heritage, flood-prone, bushfire-prone or sensitive land
Fences near road intersections affecting sight lines
Pool safety barriers, which follow separate pool safety laws

How the Two Layers of Rules Work Together

For most Sydney fences there are generally two separate questions. First, is the fence permitted to be built under planning rules? That is governed by NSW exempt and complying development provisions and your council's local controls, and it depends on height, material, location and any overlays on your land. Second, if it is a dividing fence between neighbours, who pays? That is a separate matter under the Dividing Fences Act 1991, with guidance available through NSW Fair Trading.

In practice, a straightforward replacement dividing fence at a normal height is often exempt from planning approval but still requires you to reach agreement with your neighbour about the fence and its cost. A taller, decorative or front-of-property fence is more likely to need a formal approval pathway. Pool fences sit outside all of this — they must meet strict, separate swimming pool safety standards regardless of general fencing exemptions. Because the thresholds and overlays differ from council to council, we always recommend a quick confirmation call to your council before committing to a design.

What Should You Do Before Building a Fence?

The safest approach is to check first and build second. Here is a simple sequence that suits most situations.

For a standard replacement fence

Confirm the height and material you are planning are within your council’s exempt limits, then reach written agreement with your neighbour on the type and cost share. This covers most everyday dividing fences.

For a taller or front feature fence

Contact your council early. Taller fences, solid front fences and anything decorative or unusual may need a development application or complying development certificate, and it is far cheaper to confirm this before work begins.

For heritage, flood or bushfire land

Assume approval is likely and check with your council first. Overlays on your property commonly change what is allowed and may require specific materials or a formal assessment.

For anything near a pool

Treat it as a regulated pool safety barrier, not an ordinary fence. Pool barriers must meet separate swimming pool safety standards and require certification, so specialist compliance advice applies.

The bottom line: many everyday fences in NSW are exempt from approval, but plenty are not, and the details depend on your council and your property.
