Fences, retaining walls and crossovers: check the right permit
Compare building and planning thresholds, separate neighbour agreement from approval, and prepare one clear drawing for quotes and enquiries.
Separate the fence, wall and crossing
Show each part on the same drawing, with heights and ground levels. Ask the relevant person to identify the approval or design question for that part.
Prepare the enquiry →A 1.5 m timber front fence, a 1.5 m brick front fence and a fence on a retaining wall do not have the same approval pathway. Material, street position, ground levels and overlays matter. A crossover also needs its own Council permission for work across the road reserve.
Keep the fence, retaining wall and vehicle crossing as separate items on the same sketch and quote. That makes it easier to identify who designs, approves and pays for each part.
Building-permit thresholds for fences and walls
| Proposed work | Starting point for a building permit | Important qualification |
|---|---|---|
| Front fence within 3 m of a street alignment | Required above 1.5 m for non-masonry fencing; above 1.2 m for masonry, concrete or similar materials. | Street alignment is the title boundary, not the kerb. Planning and siting controls remain separate. |
| Fence elsewhere on a side or rear boundary | Required above 2 m. | Closer to a street or corner, the lower thresholds can apply. |
| Fence near a street corner | Required above 1 m above the footpath within 9 m of the intersection of street alignments. | Show both roads and the corner on the plan. |
| Fence forming a pool or spa safety barrier | The ordinary fence exemption does not apply. | Ask the building surveyor before replacing or changing the barrier. |
| Retaining wall | A wall 1 m or higher needs a permit; a lower wall can need one too. | The exemption is for a wall below 1 m that is not associated with other building work or protection of adjoining property. |
These are the Schedule 3 items 10 and 15 building-permit checks, also explained in Council’s fence guidance. Item 10 excludes fences around children’s-service outdoor play spaces as well as pool barriers. Part 5 siting requirements are a different check; meeting a permit exemption is not an approval of every fence design.
A building exemption can still leave a planning permit
| Control on your property | Fence triggers to check |
|---|---|
| DDO2 or DDO3 | Planning permit required for a front fence over 1.8 m or less than 50% transparent; a side/rear fence over 2 m; a fence within 6 m of public foreshore land, a cliff edge or cliff face; or fibro-cement-sheet fencing. |
| EMO7 | Planning permit required for a masonry/concrete fence over 1 m, or a fence that obstructs or redirects surface water, including a continuous impermeable base. |
Read the applicable DDO2, DDO3 or EMO7 schedule. Other controls and vegetation work may add requirements. The DDO front-fence threshold does not replace the lower building-permit threshold for some materials.
Example: a 1.4 m solid timber fence within 3 m of the front street boundary and away from a street corner may fit the ordinary building-permit height exemption. On DDO2 land, its lack of transparency still triggers a planning permit. Making the same fence brick would also cross the 1.2 m building-permit threshold.
When a wall changes the question
Record existing and proposed levels on both sides, the retained height, nearby buildings and driveways, and whether a fence sits above the wall. A short wall supporting adjoining property is different from a small freestanding garden border. Give these facts to a building surveyor and ask whether engineering design and protection work are required; do not select footings from an online sketch.
If you are unsure where the boundary lies, a licensed land surveyor can establish it. Council warns that an existing fence is not guaranteed to sit on the title boundary.
A crossover needs a separate application
The crossing is the driveway section between your boundary and the road. Council requires a vehicle crossing permit to construct, remove, alter or upgrade it. An approved house plan showing a driveway does not itself authorise that work. Access to a Transport Zone 2 road also needs the relevant planning permission before the crossing permit.
Prepare a site plan showing crossing dimensions, frontage, boundaries, nearby roads, existing crossings and public assets such as trees, pits and poles. Photographs support that plan rather than replace it. Include the permit’s inspections and any traffic-management requirements in the contractor’s scope.
Council’s crossing FAQ also covers tree clearance, intersections and repairs. Check the issued conditions before booking construction or a concrete pour.
Agree on scope and cost before work starts
Permission to build does not decide the neighbour’s contribution. Use Council’s fencing and notice guidance to agree the proposal and follow the relevant process. Do not assume a retaining wall is automatically a shared dividing-fence expense.
Ask for separate prices for the fence, wall, earthworks, drainage, crossing, permits and disposal. Identify who supplies surveyed boundaries, structural design and inspections. A useful question is: “Which part of this quote depends on an unconfirmed approval, boundary or ground level?”
AI can turn your measurements and documents into a comparison sheet or covering enquiry. Keep estimated levels marked as estimates. It cannot locate a legal boundary, assess stability, design drainage or decide a neighbour’s legal liability.
