Do I need a building permit?

You don’t always need a building permit for building projects. However, you must make sure all building projects, even those that don’t require a permit, meet building regulations.

If you are an owner-builder, you must carry out a self-assessment to ensure the project is compliant.

Check the list below for common types of building projects and whether they require a permit. If you have any doubts or questions, please contact the Building Services team at Council.
