Fences and Retaining Walls

Retaining Walls

Due to the natural topography within Denham townsite, the use of retaining walls can be a necessity for building, to address moderate slopes or differences in levels on site.

Building large retaining walls on the boundaries of lots can cause negative visual impact on neighbours, and may not be the best design response to natural landform.

For residential development, most retaining walls require planning approval and a building permit. Retaining walls are assessed in accordance with the Residential Design Codes and the Building Code of Australia.

If you require approval for retaining walls, you will need to lodge detailed plans to the Shire showing existing natural ground levels, proposed ground levels (excavation/fill) and retaining wall heights in Australian Height Datum (AHD). You may need to engage a licensed surveyor to provide the existing ground levels.

Engineering certification of the retaining walls may be required at planning application or building application stage.

If you propose any retaining walls on a vacant lot or as part of building site works, please contact the Shire's Consultant Planning Officer, Liz Bushby, at Town Planning Innovations by email liz@tpiplanning.com.au or call 0488 910 869 (Tuesday-Friday).

Dividing Fences

Dividing fences require a Building Permit when proposed in wind region C as defined in Australian Standard 1170.2. This includes Denham Town site which is in wind region C.

Dividing fences are controlled by the Dividing Fences Act 1961.

The construction of new dividing fences or repairs to existing dividing fences should be discussed between the affected parties. The Shire of Shark Bay does not become involved in any civil issues arising from a dispute over a dividing fence. 

To help property owners understand the law behind dividing fences, the Building Commission within the Department of Commerce has produced a comprehensive information booklet: Dividing Fences – Rights and Responsibilities
