Building and renovating a home

This page has information on building work in the Northern Territory that is prescribed by law. 

If your building work is prescribed, you must use a registered builder or contractor.

Your building work is considered prescribed if it's worth more than $12,000 and involves one of the following buildings:

• a class 1a building, for example a single dwelling, a detached house or attached townhouses or duplexes
• a class 2 building, for example attached units or flats
• extensions and renovations to class 1a or class 2 buildings where the floor area is increased
• a class 10 building - for example a garage, carport or shed - attached to and built at the same time as a class 1a or class 2 building
• a retaining wall - whenever built - that is not attached to a class 1a or class 2 building but on which the integrity of such a building depends
• the relocation of an existing building.
