What is a dividing fence?

A dividing fence is usually a 'sufficient fence' that separates the land of different owners. It does not include a retaining wall.

Dividing Fences Act 1961

  • The Dividing Fences Act 1961 (the Act) combines with local government by-laws to regulate the erection and maintenance of dividing fences in Western Australia.
  • The Act provides a process for sharing costs between neighbours, the determination of boundaries and a mechanism for courts to deal with disputes over fences.
  • It does not apply to retaining walls, fence height restrictions or encroachments.
  • The Dividing Fences Act was developed by the Government of Western Australia, Department of Commerce, Building Commission.

What does the City do?

The City will respond to complaints about:

Approval requirements

  • Building approval is required when a brick or masonry fence exceeds 0.75m in height.
  • Generally, the City does not require building approval to construct a dividing fence using materials such as cement-fibre sheets, colourbond or timber erected in accordance with manufacturers specifications.
  • The minimum acceptable design and height for a sufficient residential dividing fence for suitably capped fibre cement sheets and colourbond is to a height of between 1.8m to 2.2m from the higher ground level to either side of the boundary.
  • All gates in fences must open into the property and not out onto streets, footpaths and verges.
  • Dividing fences, unless designed to do so, are not to be used as a retaining wall.
  • Barbed wire, electrified and other dangerous fencing materials are not permitted in residential areas. Some exemptions may apply in rural, commercial or industrial zones

Building or repairing dividing fences

  • When building a new, fence (or repairing dividing fences), the placement and cost of the dividing fence is a civil matter between adjoining land owners.
  • Residents are advised to liaise with their neighbour in the first instance.
  • The Building and Energy website contains a brochure 'Dividing Fences - A Guide' which provides information on entering into negotiations with your neighbour.
  • In some cases, you may need to apply to your local government for planning and/or building approval to build or alter your dividing fence (refer Approval Requirements above).

Asbestos

  • Fencing complaints can also relate to issues with fences made from asbestos.
  • If you are reporting an issue with a fence and you are concerned about asbestos, please refer to Asbestos knowledge to ensure health risks are raised as a priority.

Dividing fence disputes

  • Dividing fence disputes between adjoining neighbours that cannot be resolved should be referred to a solicitor for legal advice.
  • Neighbour disputes can be referred to Citizens Advice Bureau, who may be able to provide advice and assistance.

Who pays for dividing fences?

  • Generally neighbours are liable to evenly share the costs of installing a dividing fence.
  • Government bodies (including local government) are exempt under the Act from contributing to the installation, maintenance and all associated costs pertaining to dividing fences.
  • Residents whose properties adjoin State Land are solely responsible for their boundary fence installation and maintenance.

Retaining walls

A person seeking to alter the ground level at or near the boundary of their lot, by either filling above or cutting below the natural ground level, is responsible for providing a suitable retaining wall.
