Construction of a principal building or renovation of an existing principal building

A building permit is required for the construction of a new principal building or for the renovation of an existing principal building.

A building permit is required for any works where costs before taxes exceed $10,000, including labour and construction materials.

A building permit is required regardless of the costs for the following works:

  • Foundation, structural or internal partitions;

A building permit must be issued if the works to be carried out require one. Failure to obtain a building permit can result in significant costs, penalties and other unfortunate consequences.
