If you want to make a change to any wall, floor or ceiling within a building by removing, adding or altering its size, shape or location, this is known as an internal alteration.
The City can help you get the Building Permit approval needed before you undertake any work.
Call 9186 8555 to speak with the Building Services team about internal alterations.
A Building Permit approval is required for all internal structural alterations.
A Building Permit is not required if the works being undertaken don’t affect existing structural elements or walls designed for internal pressure, and the works are to be undertaken according to the applicable building standards required in the National Construction Code (NCC).
For example, the re-fit of an existing bathroom would not require a building permit if the waterproofing and plumbing work is undertaken according to the building standards in the NCC.
Either the property owner or the builder must submit the application.
The level of information required will depend on the scope and extent of the alterations.
