Granny flats in NZ are about to become a whole lot easier to build. The New Zealand Government has announced a new policy aimed at relaxing the rules around building small dwellings, like granny flats, on existing residential properties. While the full details are still being finalised, the direction is clear: building a granny flat will soon require fewer consents, less red tape, and open up more housing options for homeowners.

What Are Granny Flats?

Granny flats, also known as minor dwellings or secondary dwellings, are self-contained homes that sit on the same property as the main house. They can be used for extended family, guests, or as rental income. Popular search terms include "granny flats NZ", "minor dwellings North Island", and "small homes for families NZ."

What Are the New Rules?

While the full legislation is still being drafted, here’s what we know:

• No Building Consent Required: The government intends to allow granny flats of up to 70 square metres to be built without needing a building consent in most areas.

• Faster Approvals: Councils will no longer have to process time-consuming consent applications for compliant granny flats.

• Nationwide Consistency: The rules will apply across the country, making the process easier no matter where you live in New Zealand.

These changes are part of a broader building reform and are expected to take effect mid to late 2025.

What This Means for Homeowners

For homeowners and property investors in the North Island, the new granny flat rules open up exciting possibilities:

• Extra Income: Rent out your granny flat for long-term or short-term accommodation.

• Multigenerational Living: Keep family close while giving everyone their own space.

• Increase Property Value: Add a secondary dwelling and instantly boost the value and appeal of your property.

Key Considerations

Even with the relaxed rules, you still need to think about:

• Site Suitability: Is there enough room on your section? Will access and drainage be sufficient?

• Design & Planning: A smart design will ensure your granny flat fits the site and blends with the main dwelling.

• Zoning Restrictions: While rules are easing, local plans may still limit certain aspects like total site coverage.
