Building works that may need building approval
The following types of building works may need building approval. A building designer, architect or Private building certifier may be able to help you with the design and approval process. For information on how to obtain a building approval, please refer to our Role of a private certifier page.
Generally, all shade sails need building approval.
The exception is small, low shade sails less than 2.4 metres high (2.1 metres mean height), 10 square metres, 5.0 metres long and not located in any setback areas.
A new timber deck is likely to need building approval from a private certifier.
These may also need the City’s approval for building within setbacks if they are over 1.0m high. The private certifier arranges this.
Example when building approval is required
For a deck as an elevated platform supported off the ground at any point, building approval is required unless smaller than 10 square metres, less than 1.0m high and meeting all building requirements.
Example when building approval is not required
For landscaping timber on natural ground (no posts or supports) approval is not required when in continuous ground contact and meeting all building requirements.
Consideration must also be given to:
- Building code fire separation requirements when less than 900mm from property boundary
- Termite protection to adjacent buildings
- Durability when close to ground
Unroofed pergolas don't need building approval when less than 2.4 metres high (2.1 metres mean height), 10 square metres, 5.0 metres long.
When in a setback area, unroofed pergolas can't be used for entertainment and can only be ornamental or horticultural use.

The exception is for small, low-roofed patios less than 2.4 metres high (2.1 metres mean height), 10 square metres, 5.0 metres long and not located in any setback areas.
Because of their height, these need building approval.

Minor repairs or maintenance to existing buildings that don't affect the structural or fire safety of a building may not need building approval.
The use or classification of a building must stay the same as the building approval.
For example, a family want to disable their garage door to use their garage as an extra bedroom or lounge. Because of the change of use, a building approval is needed even though no building work is to be done.
A building approval is required if roofing works involve replacing more than 20% per cent of the existing roof area. The building approval must be obtained by either the roofing contractor or the property owner.
The building approval is required if a roof is being replaced due to age and disrepair, or, for example, under an insurance claim following damage from a severe weather event.

Either a building approval or a camping area licence is needed for living in a caravan or tiny house on wheels on your property.
Tiny houses need a building and plumbing approval just like a normal house.
When they include their own bathroom, laundry and kitchen there are also planning issues to check such as a secondary dwelling or dual occupancy use.
Tiny houses don't include registered vehicles, or vehicles which can be registered. These vehicles are administered under our local law, which also restricts their use as accommodation.
For more information including licence applications as a vehicle, visit Camping area licence.
Caravans that are no longer registered and moveable are classed as a permanent structure and will require relevant approvals by law and City Plan.
