Granny Flats without consent? Government says Yes (from 2026)
The dream of building a “granny flat” in the backyard, whether for extended family, extra rental income or simply greater flexibility, is about to get a lot more achievable.
New Zealand’s Parliament has passed the Building and Constructions (Small Stand-Alone Dwellings) Amendment Bill, which will come into effect in early 2026. The new law will allow certain small, stand-alone homes to be built without needing building consent, under clear and safe conditions.
What will the new law allow?
From 2026, homeowners will be able to build a single-storey, stand-alone dwelling of up to 70 square metres, without applying for formal building consent, as long as:
- The design is simple and fully compliant with the Building Code (covering safety, energy efficiency, durability, and more)
- The build is carried out or supervised by a Licensed Building Practitioner (LBP)
- The homeowner notifies the Council before and after construction.
The aim is to speed up construction, reduce compliance costs, and make it easier for Kiwis to add more living space, all while keeping construction standards high.
What about Council Contributions?
Although a building consent won’t be required, homeowners will still need to obtain a Project Information Memorandum (PIM). Through this process, infrastructure contributions (e.g. for water, sewerage, and transport) can still be charged by local Councils to ensure essential services are maintained.

Complementary RMA Reforms:
In parallel, the Government plans to introduce a new National Environmental Standards (NES) to support the changes. This will allow one granny flat per property, to be built without a resource consent, so long as:
- The main dwelling and the granny flat are on the same title, and
- The property is residential or rural-zoned.
This move will help bypass some of the resource consent hurdles that currently slow down or block small-scale development.
