Do I need a building permit?

It is important to always check before you start building works to ensure you have the necessary permits.

The Building Regulations 2006 specify that the need for a building permit is based on the scope of building work rather than the value of work, which means structures such as garages, carports and pergolas need a building permit.

The table below lists common types of building work and whether you need to obtain a building permit from council.

This list is not exhaustive so please check with council before you build.
