Sheds, Patios and Carports

Residential sheds and other outbuildings

Outbuildings are freestanding non-habitable buildings. Traditionally the term outbuilding comprises of backyard sheds, workshops, garages or freestanding outside laundries and toilets that are relatively small in area and relatively low in height.

Building Permits are not required where the risk of non-compliance with the building standards is low, however; a Building Permit is required for all outbuildings that are not otherwise exempted.

Item 1 in Schedule 4 (cl.2) of the Building Regulation 2012 states that the construction, erection, assembly or placement of a freestanding Class 10a building that has a floor area of 10m2 or less and is no more than 2.4m in height does not require a building permit.

If you do require a building permit, go to Building applications and forms for more information.

If you are not sure if a building permit is required for your shed or outbuilding, please contact us.

Patios and carports

All patio and carport structures are to comply with the relevant provisions for front setbacks under the Residential Design Codes of Western Australia.
