Build a Granny Flat in Auckland

Big changes are making it easier for Auckland homeowners to add a granny flat or small standalone home to their property.

From 15 January 2026, new government rules allow some small homes under 70m² to be built without a building consent, provided they meet specific design and safety requirements. That means building a granny flat in Auckland could soon be simpler, faster, and more affordable than before.

What the New Rules Mean for Auckland Homeowners

If you’ve been thinking about adding extra space, these changes are designed to help make it happen.

A granny flat can be a great solution for:

  • A place for Mum or Dad

  • Space for growing teenagers

  • Guest accommodation

  • A home office or hobby space

  • Extra room for extended family

While the process is becoming easier, your Auckland granny flat will still need to meet New Zealand Building Code standards and comply with Auckland Council planning rules, including zoning, site coverage, and services.

Our local team can help you understand what’s possible on your property and guide you through the requirements.

Getting Your Auckland Granny Flat Right

Every Auckland property is different, and costs can vary depending on your site, council requirements, and services. That’s why it pays to get expert advice from the start.

Our local builders can guide you through every step of the process, including:

  • Understanding what’s possible on your Auckland site

  • Navigating council rules and compliance requirements

  • Planning your granny flat layout and size

  • Preparing for building under the new 2026 rules

With over 60 years of experience building practical, high-quality homes for Kiwis, we make it simple to turn your Auckland property into a space that works for you.

Talk to our team today and get personalised guidance for your granny flat or small home.

For more detail, you can check the latest updates on the Government’s Building Performance website.

You’ll still need to meet New Zealand Building Code requirements, and the home must meet the eligibility criteria for your property and local planning rules, but overall, this change will make adding a granny flat simpler, faster, and far more affordable.
