new rules

A simpler process for all

New national rules mean you can now build a 70m² minor dwelling (granny flat) without a building consent. The process is simpler but what you can place on your land still depends on planning rules, site conditions, and smart design choices.

At Tiny Home Base, we help you understand what’s possible on your property and match you with a ready-to-go cabin or granny flat that fits the new rules without long build wait times.

Important Update on Building Rules

The rules around building a granny flat in New Zealand have changed. While the consent pathway is now simpler, understanding what works on your specific site still takes experience and clear advice.

Tiny Home Base specialises in cabins and minor dwellings you can view, walk through, and buy today. Whether you’re creating space for family, adding a rental, or setting up a self-contained studio, we’ll help you navigate the new 70m² exemption with confidence and without unnecessary delays.

What the New Rules Allow

From 15 January 2026, homeowners can build a stand-alone, single-storey dwelling up to 70m² without needing a building consent.

These dwellings commonly referred to as granny flats or minor dwellings must still meet the New Zealand Building Code, but the overall process is faster and more accessible.

Key requirements include:

  • Maximum internal floor area of 70m²
  • Single-storey, stand-alone structure
  • Simple, code-compliant construction
  • Work completed or supervised by licensed professionals
  • Council notification before and after the build (via a PIM and final documentation)

The exemption removes building consent paperwork and not the need for quality, compliance, or smart planning.

Why a Site Assessment Still Matters

Every site is different. Zoning rules, setbacks, hazards, and service connections all affect what you can place on your land, and where. 

That’s why the first step is understanding your site. 

We help assess: 

  • Zoning and planning requirements 
  • Setbacks, site coverage, and height limits 
  • Flood, wind, seismic, and coastal considerations 
  • Access to power, water, wastewater, and stormwater 
  • Which cabin layouts will work best on your property 

This gives you clear direction upfront, before you commit to a cabin.

FAQs

Common questions

What is the maximum size for a granny flat without building consent?

The new exemption applies to eligible minor dwellings with a maximum internal floor area of 70m². They must also meet requirements around construction, design and professional supervision.

Does the 70m² rule mean I can put a granny flat anywhere on my property?

No. Removing the need for a building consent does not remove planning requirements. Your property's zoning, setbacks, site coverage, height limits, natural hazards and access to services can all affect whether a granny flat can be placed on your site and where it can go

Do I still need to notify the council if my granny flat does not need building consent?

Yes. The exemption still involves council notification before and after the work, including the required property information and final documentation. It is a simpler pathway than a full building consent, but it is not a completely council-free process.

Can a consent-exempt granny flat have a kitchen and bathroom?

A minor dwelling can be designed as self-contained accommodation, but all plumbing, drainage, building work and services still need to meet the applicable requirements. Whether a particular cabin and site qualify under the exemption should be confirmed before you proceed.

Does a granny flat still have to meet the Building Code?

Yes. The exemption removes the requirement to obtain a building consent for eligible dwellings; it does not remove the requirement for compliant construction. The dwelling must still meet the relevant requirements of the New Zealand Building Code.

Can I use a granny flat for family accommodation or as a rental?

A granny flat can provide independent accommodation for family and may also suit rental use, but how you intend to use the dwelling can interact with local planning and property requirements. It is important to check what is permitted on your particular site before purchasing.
