Granny Flat Legislation Passed: What It Means for Kiwi Homeowners

In a move to address housing affordability and flexibility, Parliament has officially passed the Building and Construction (Small Standalone Dwellings) Bill, allowing homeowners to build granny flats up to 70 square metres without needing a building consent.

 

What’s Changed?

The new law removes the requirement for building consent for small standalone dwellings (commonly known as granny flats) provided they meet specific criteria.  This reform is designed to streamline the building process for simple, low-risk structures and empower families to create housing solutions that suit their needs.

 

When Does It Take Effect?

The exemption will come into force in early 2026, once supporting regulations and guidance materials are finalised.  Homeowners can begin planning now, but construction must not begin until the exemption is officially active.

 

Key Conditions

To qualify for the consent-free build:

  • The granny flat must be simple in design and no larger than 70m².
  • It must comply with the New Zealand Building Code, including safety, insulation, fire protection, and sanitation standards.
  • Construction must be carried out by authorised building professionals.
  • Homeowners must notify their local council before and after construction.

 

Why It Matters

This reform is expected to:

  • Enable the construction of 13,000 new granny flats over the next decade.
  • Provide affordable housing options for extended families, disabled individuals, rural workers, and first-time renters.
  • Reduce pressure on councils by removing unnecessary consenting burdens for simple builds.

 

What’s Next?

The Government is preparing:

  • A National Direction under the Resource Management Act to remove resource consent requirements.
  • A suite of forms, templates, and guidance materials for homeowners, councils, and builders.

 

Final Thoughts

This legislation marks a significant step toward more flexible and affordable housing in New Zealand.  Whether you’re planning to house a family member, create a rental unit, or simply expand your living space, the new rules make it easier than ever to get started.
