Granny Flat Rules Are Changing: What It Means for Kiwi Homeowners

Home / Granny Flat Rules Are Changing: What It Means for Kiwi Homeowners

Thinking of adding a granny flat or secondary dwelling to your property? Now might be the perfect time to start planning. The New Zealand Government is proposing exciting changes to make it easier and faster to build a granny flat – with new legislation expected to take effect in early 2026.

These proposed updates could dramatically simplify the process of building a small prefab home or granny flat in NZ, especially for homeowners with underutilised land. But there’s a catch: the rules haven’t passed yet, and the final details may still change.

Here’s what you need to know – and how Ezyline Homes can help you get started.

What’s Being Proposed?

Under the draft changes, you could soon be able to:

✅ Build a secondary dwelling up to 70m² on your property
✅ Do it without needing a building consent
✅ Skip the need for site consent as well

These updates would reduce costs and red tape for many homeowners looking to build granny flats, sleepouts, or extra accommodation – great news for families, retirees, or anyone needing affordable housing solutions.

Key Rules to Keep in Mind

Even with the proposed changes, some important conditions will still apply to any secondary dwelling built without consent:

  • The structure must be simple in design, using lightweight timber or steel framing and lightweight steel roofing.
  • It must comply with the New Zealand Building Code.
  • Plumbing and drainage must follow accepted Building Code solutions.
  • The dwelling must be built at least 2 metres away from any boundary or existing structure.
  • It must be constructed or supervised by a Licensed Building Practitioner (LBP).
  • Smoke alarms, heating, and connections to water/sewerage systems are required.
  • You must notify your local council when the project begins and ends.
  • Council contributions may still apply under a Project Information Memoranda (PIM).

Planning to Build Now? Stick With Current Rules

While the proposed legislation opens exciting possibilities for the future of granny flats in NZ, it’s important to note that none of the changes are law yet. If you’re planning to build now, you’ll need to follow current consent and compliance processes.
