Tiny house rules in New Zealand — the 2026 70 m² exemption explained

Updated 5 September 2026

New Zealand made the single most tiny-house-friendly rule change of 2026 — and it does not apply to tiny houses on wheels. Here is what it does and doesn't do.

The 70 m² exemption

Since 15 January 2026 you can build a small standalone single-storey dwelling of up to 70 m² on most residential sites without a building consent, and in most cases without a resource consent, provided the design is simple, the work is done or supervised by Licensed Building Practitioners, it fully meets the Building Code, and you notify your council before you start and when you finish. MBIE estimated the change would add almost 13,000 dwellings over a decade. The catch: nobody above your builder signs the work off any more, so the builder you choose matters more than the rule.

Tiny houses on wheels

MBIE's January 2026 guidance is clear that a tiny house occupied on a permanent or long-term basis is a building under the Building Act and must comply with the Building Code regardless of wheels. If it is genuinely movable and used like a vehicle, vehicle rules apply — it can be both. The 70 m² exemption is for buildings fixed to land, not trailers.

Money and insurance

A home on wheels cannot be used as mortgage security, which pushes buyers into personal loans at roughly two to three times home-loan rates, and insurers may treat it as neither house nor caravan. A consented (or exempt-but-compliant) minor dwelling on foundations is the easier asset to finance and insure. Some councils discount development contributions — Tasman District by up to 50% for a minor dwelling under 110 m².

What to do

• Decide first: fixed minor dwelling (exemption route) or tiny house on wheels (vehicle route).
• For the exemption, confirm your site's zoning allows a second dwelling and that services can be connected.
• Use an LBP for design and build, and keep the pre- and post-build council notifications.
• For a home on wheels, confirm how your district plan treats long-term occupation before you buy.
