Building a garden shed, carport, fence or shade structure
This page has information about when you need a building permit to build a garden shed, carport, fence or shade structure in the Northern Territory (NT).
You will usually need a permit unless your structure meets the criteria for exemptions from building approval.
There are exemptions for garden sheds, fences, and shade structures, however you will need building approval for a carport.
There are no exemptions for constructing a carport.
How to get building approval
You can get building approval from either of the following:
- an approved self-certifying manufacturer
- or a registered NT building certifier.
Engage a self-certifier
A self-certifier is someone approved to build and certify the construction of certain products such as garden sheds, carports, fences or shade structures, and who can be engaged instead of a building certifier.
Self-certifiers must be able to both supply and install the product.
They can only certify products for their approved uses and must ensure that the construction complies with approved plans and legislation.
They can also issue occupancy permits for the completed structure.
You may also choose to buy a product from a self-certifier but get building approval through a building certifier.
To check if a person is a self-certifier for a particular product, ask to see their self-certifier approval.
You can also find a self-certifier by contacting Building Advisory Services.
Call (08) 8999 8985 or email email@example.com.
Use a building certifier
You may prefer to engage a building certifier if the product you are installing is not approved for self-certification, if you want to build it yourself, or you are having other work done and want to include the installation in the same building permit as your other work.
