Carports

A Carport is defined under the Building Regulations 2006 and Building Code of Australia as a structure used to house motor vehicles, which has a minimum of two sides "open" and not less than one third of its perimeter "open", and for the purpose of this definition, a side is considered to be open if the roof covering adjacent to that side is not less than 500 mm from another building or allotment boundary. Also, the structure must have non-combustible roof claddings and linings including gables.

A Carport is classified under the Building Code of Australia as a Class 10a. A Carport may be Sited on or within 900 mm of an allotment boundary, provided it meets the criteria and definition of a Class 10a – "Carport" structure as described above.

As with the Siting of any proposed structure there are limitations on construction. The Building Regulations impose limitations on building heights and lengths, setbacks from the front, rear and side boundaries, maximum site coverage, etc. Please refer to the "General Siting Requirements for Single Dwellings and Outbuildings" for full ResCode Siting information.

Identifying a Carport: Refer to Figure 3.7.1.7, Building Code of Australia – 2001-09-21 for a diagrammatic illustration of the above definition.

Fences

A Fence is classified under the Building Regulations and Building Code of Australia as a Class 10b structure. Part 4 of the Building Regulations regulates the Siting and height limitations of proposed fences. Refer to the ‘General Siting Requirements for Single Dwellings and Outbuildings’ for full Siting information.

A Building Permit is required for a proposed front fence or side fence on a corner block exceeding 1.2 metres in height within 3.0m of the properties front boundary. A side boundary fence dividing two properties greater than 2.0m in height also requires a Permit.

Boundary fences dividing two properties up to 2.0m in height and greater than 3.0 metres back from the frontage are unregulated, do not require a Building Permit and should be treated as a civil matter as these fences are usually in joint ownership.

A retaining wall structure which may be considered a fence requires a Building Permit when this structure is retaining more than 1.0m in the vertical plane or is constructed on a site boundary.

Irrespective of whether a Building Permit is required or not, all fences and retaining walls must comply with the Building Regulations 2006 and Building Code of Australia.
