If you are planning to change a building's established use, you must give Council written notice of the proposed changes.
Common examples of changes of use are:
- residential house to restaurant
- warehouse to apartments
- dwelling to childcare facility.
A change of use can trigger Building Code compliance issues and certain systems or elements within the building may require changes or upgrading.
Changing part of an existing building can trigger the need to upgrade the whole building. For example there may be a change to crowd activity, that changes the category of the building.
How you can use all or parts of buildings is specified in Schedule 2 of the Building Regulations and Section 115 of the Building Act 2004.
