Do I need a building permit?
Whenever you construct, extend or modify a structure you will need a building permit.
Most building work in Victoria requires a building permit, and you must obtain the permit before starting any works.
Building permits are documents certifying that a proposed building complies with the relevant building regulations.
To apply for a building permit, you will need to complete Application for Building Permit(PDF, 266KB), submit plans and other required documentation to demonstrate the proposed building work will comply with the Building Regulations.
Do I need a building permit?
The table below is an extract from the Victorian Building Authority (VBA) and should be used as a guide only. It is important to contact a building officer before building or undertaking any works. It is also important to consult with Council to find out whether a planning permit is required for any of the proposed works. A planning permit is required prior to a building permit being issued and works commencing.
We recommend you view the VBA's full listing: When is a Building Permit required?

Are there exemptions?
Some minor building work does not need a building permit or occupancy permit. We suggest getting the advice of a building practitioner if you are seeking a building permit exemption. To be exempt, the property owner must be able to demonstrate full compliance with the building regulations.
