Building approval for change of use
Although you may not need planning approval for a change of use, you may still require other approvals, for example:
- environmental health approval if you plan on starting a food, beauty or hairdressing business
- building approval (a building permit) for any internal fit-outs, change of building classification, construction or demolition work.
If the change of use changes the classification of the building, you may need to do building work to meet the relevant building standards and the National Construction Code. This will require you to apply for a certified building permit.
A building permit is required for:
- structural works
- changes to the internal layout which alters the requirements of the National Construction Code
- changes to the fire safety features of the building e.g. exit signs, fire sprinklers etc.
You will also need to apply for an Occupancy Permit (BA9) following completion of the works, or if the change of use changes the classification of the building, or if you make changes to the fire safety features of the building.
Please see our building forms and documents page for more information on application forms and checklists for submitting a building application.
Please see our health forms and documents page for more information on submitting a health application.
