New Law Makes It Easier to Build Granny Flats
A housing reform passed on 24 October 2025 allows certain standalone secondary dwellings (granny flats) up to 70m² to be built without full building or resource consent. The goal is to remove red tape and make it easier for property owners to create multi-generational living spaces or independent accommodation on existing land.
