NZ Government Announces Bigger Granny Flats Now Allowed Without Consent
If you’re thinking about building a granny flat, minor dwelling, or sleepout on your property—things just got a whole lot easier.
The New Zealand Government has just announced major changes that make it simpler (and more affordable) to build larger secondary homes without the red tape of a resource consent. Under the new rules, you’ll be able to build granny flats up to 70 square metres without needing a resource consent, as long as they meet certain building code standards and local council rules.
This is a big step forward in making it easier for Kiwis to add value to their properties, house family, or even create extra rental income.
What does this mean for Canterbury property owners?
For homeowners across Canterbury, especially in areas like West Melton, Rolleston, Lincoln, Darfield, Prebbleton, and beyond, this change opens the door to more flexible housing options. Whether you’re looking to build a space for elderly parents, a home office setup, or a self-contained rental unit, the new rules make the process quicker and less complicated.
At Canterbury Cottages, we’ve always believed in smart, functional living spaces that suit the Kiwi way of life. These new consent-free builds are perfect for the kinds of granny flats, sleepouts, cabins, and cottages we specialise in.
Why the change?
The Government says the aim is to cut down on red tape, support housing growth, and give New Zealanders more freedom on their own land. It’s part of a wider effort to unlock the potential of small-scale, self-contained homes—especially at a time when many families are looking for affordable solutions to multigenerational living.
Things to keep in mind
You’ll still need to meet building code and district plan requirements, and some councils may have infrastructure or service connection rules.
Building and Construction Minister Chris Penk confirmed building consents would not be necessary if the granny flat had a simple design, it met the Building Code, the construction was done by authorised builders and if homeowners notified their councils at the beginning and end of construction.
But removing the need for a resource consent can mean big savings in time and money—making now the perfect time to consider a minor dwelling on your property.
The necessary legislative changes were expected to make it through Parliment by the end of the year.
National minister Chris Bishop, responsible for Resource Management Act reform, said a new National Environmental Standard (NES) under the RMA would be developed and in place by the end of 2025 to align with the required amendments to the Building Act.
