Building work listed under Schedule 1 of the Building Act 2004 is exempt building work and may be done without first obtaining a building consent, but the work must still comply with the Building Code.
Schedule 1 can be viewed on the New Zealand Legislation website. Further information which may be relevant can be obtained on the Ministry of Business, Innovation and Employment website and in the MBIE Schedule 1 Guidance document.
The granny flats exemption (also known in legislation as non-consented small standalone dwellings) under Schedule 1A of the Building Act 2004, enables eligible dwellings of up to 70 square metres to be built without a building consent, provided that certain conditions have been met, including applying for and receiving a PIM. More information about this can be found on our Building a non-consented small standalone dwelling (Granny Flat) page.
It's also recommended you check to see if your proposed building work complies with the requirements of the District Plan, or is already provided for by an existing Resource Consent. If it isn't, you may need to apply for Resource Consent. Contact Council’s Consents team for more information.
