From January 2026, homeowners can build granny flats up to 70m² without a building consent, provided the dwelling is simple in design, meets Building Code requirements, and is built or supervised by licensed professionals.
This major change makes it easier for families, investors, and homeowners to maximise the use of their land.
Even though a formal building consent is no longer required for qualifying dwellings, homeowners still must notify the council before starting and after completing their build, and ensure the dwelling is fully compliant.
This is where THS offers a huge advantage.
