Granny flats building consent exemption becomes law today!
A new granny flat can now be built without a building consent if:
it is a single-storey, standalone dwelling
it is no bigger than 70 square metres
it has a simple design and meets the Building Code
all exemption conditions are met
the work is done or supervised by licensed building professionals (LBPs, plumbers, drainlayers, gasfitters, electrical workers), as it is restricted building work.
Homeowners MUST get a Project Information Memorandum (PIM) from their council before building work starts. When the build is finished, they must tell the council by providing documents like final plans, Records of Work, and certificates of compliance.
If you are interested in a granny flat build, or are unsure whether any building work needs a building consent, I am here to help.
