Applying for an extension to a building's specified life
You, as the building owner, must give us written notice if you want to extend the life of your building.
You will need to state why you want an extension and how long the extension should be.
The building will also need to be re-inspected to ensure it complies with section 112 of the Building Act.
You can also get free advice from us in person.
We can grant an 'extension of life' on your request, if we are satisfied the building can satisfactorily perform for a further specified time.
See Change of use, alterations and extension of life on the MBIE website.
