You may need to apply for a Building Permit from the City for a new patio, pergola, shade sail, shed or other minor structure before the proposed structure can be constructed. Find out when a building permit is required and if you also require planning approval.
In most instances, a Building Permit must be obtained from the City prior to building work being carried out for a patio, pergola, shade sail, shed, water tank or minor structure.
A pergola is an open-sided structure that is supported by columns or posts. It generally has an open roof or a permeable roof cover (eg. shade cloth). A pergola may be freestanding or attached to the dwelling.
It should be noted that a pergola with an impervious roof covering (eg. colorbond or polycarbonate sheeting) is considered a patio by the City.
When is a Building Permit required for a pergola?
You will need a permit for an unenclosed pergola that is more than 20m2 in area and/or is more than 2.4m in height.
Please visit the Building Permit Application page for more information on how to submit a Building Permit application for a pergola.
If a pergola is less than 20m2, a building permit will not be required.
A shade sail is a piece of permeable fabric that is fixed to timber or metal posts to provide shade to an outdoor area. Please note a shade sail made from impervious fabric (i.e. impenetrable to rainwater) is classed as a patio by the City.
When is a Building Permit required for a shade sail?
You will need a Building Permit for a shade sail that is more than 10m2 in area and/or is more than 2.4m in height.
Sheds can be built right up to a boundary but can be no closer than 900mm from house eaves. If this cannot be achieved, the shed must be 900mm from the boundary to comply with fire separation requirements of the Building Code of Australia.
