Starting in early 2026, New Zealanders will be able to build standalone dwellings up to 70 sqm without needing a building consent—commonly referred to as “granny flats” or minor dwellings. Through this new granny flat regulation, New Zealand aims to increase the availability of affordable housing, expedite development, and provide homeowners with greater flexibility, particularly in high-demand areas such as Auckland.
A lot of homeowners are already exploring options for new granny flats. With the growing interest in granny flats in New Zealand, this change opens exciting possibilities for those seeking modern and compact living spaces.
The Ministry of Business, Innovation and Employment says that homeowners can build a single-storey detached dwelling of up to 70 sqm without building consent if the following conditions are met:
- Size and height: Must be less than or equal to 70 sqm floor area, maximum of 1 metre off the ground, and under 4 m.
- Setbacks: At least 2 m from property boundaries and other buildings.
- Materials: Lightweight roof, light timber or steel framing, and cladding under 220 kg/m².
- Design compliance: Must meet the New Zealand Building Code.
- Licensed professionals: Work must be done or supervised by licensed builders.
- Council Notification: Notify your local council before and after starting and completing the build.

Benefits of Building a 70m² Minor Dwelling in Auckland
This new exemption offers several advantages for Auckland homeowners interested in building granny flats or compact second dwellings:
- Save on building consent fees and time
- Add a second income stream via rental
- House elderly parents or adult children affordably
- Increase property value and usability
- Simplify your development journey
Land within Auckland is at a premium; a great way to maximise your property’s potential without navigating lengthy council processes is to explore granny flats for sale or engage with expert Auckland builders to design your own 70 sqm granny flat.
Key Requirements for Consent-Free Homes
Even without formal consent, all homes must still meet the New Zealand Building Code. For example:
- Safe plumbing and drainage
- Energy efficiency standards still apply
- Fire safety, ventilation, and moisture protection are required
These homes must be simple in form — ideal for sleepouts, granny flats, or compact rental units. For homeowners considering more space, options like a 2 storey house with granny flat may still require building consent, but can complement the overall property plan.
