There is not much that does not require a building permit.

Additions and alterations that modify the shape or structure of a building, including but not limited to demolishing or installing new internal walls, adding new door openings or windows all require a permit. Permits are also required new structure additions such as pergolas, carports and decks.

Building permits are enforced to ensure compliance with building codes and therefore the safety of occupants and reduction of potential health and safety risks.

Undertaking works without a permit may lead to receipt of a Building Notice, which can become and costly and drawn out process.

Building Notice

A building notice is the first step in the enforcement processes available to the Municipal Building Surveyor at Council. Where the building department becomes aware of building works being carried out without the required permits on a property that could affect the health and safety of the public and/or occupiers, a building notice can be issued requiring the property owner to ‘show cause’ why:

1. the building/works should not be demolished and/or reinstated
2. the use of the building should not be prohibited.

How Establish if a Permit is Required

It is always in your best interest to seek clarification as to whether a permit is required. This can be done via local council or a registered building surveyor.
