Questions

Granny Flat Exemption NZ: what people ask

How big can a granny flat be without building consent?

Up to 70 m², new, stand-alone and single storey, at least 2 m from any other home and any legal boundary, and no more than 4 m high above floor level, with a lightweight timber or steel frame. Plumbing and drainage must follow the listed acceptable solutions.

Do I still need to tell the council?

Yes. MBIE's guidance says to notify the council before and after the build. Before you start, apply for a project information memorandum (PIM) using Form 2AA. The work must be carried out or supervised by licensed building professionals.

What do I send the council when it's finished?

Within 20 working days of completion, the owner must send records of work, the final plans and the certificate of work. Not doing so is an infringement offence with a fine of up to $1,000.
