Granny Flats Approved for Construction From Early 2026

The Government has passed legislation which will make it easier to build small standalone dwellings – commonly known as granny flats.

The new building consent exemption for granny flats is on track to commence in early 2026, following the passage of the Building and Construction (Small Stand-alone Dwellings) Amendment Bill and supporting regulations.

What’s changing?

From early 2026, homeowners will be able to construct a single-storey, granny flat up to 70 square metres without needing a building consent if:

• The design is simple and complies with the Building Code.
• Construction is completed or supervised by licensed professionals.
• Homeowners notify their local council before they commence building and once it is completed.

The exemption will only apply to granny flats built after the new law and regulations come into effect. Any construction started before commencement will still require a building consent.

If you are unsure whether building work needs a building consent or not, check with your local council.
