Can You Insure a DIY-Built Tiny Home in New Zealand?

New Zealand has a strong tradition of owner-built housing, and the tiny home movement has enthusiastically embraced it. But when it comes to insuring a home you've built yourself, the mainstream insurance market is largely unwelcoming — and for understandable reasons. Here's what you need to know.

Why DIY Builds Are Difficult to Insure Through Mainstream Channels

Mainstream insurers evaluate building quality and replacement cost in part through proxies like building consent, code of compliance, and the involvement of Licensed Building Practitioners. A DIY-built tiny home may have none of these formal verifications.

The insurer's concern is twofold: they can't easily verify that the home has been built to an adequate standard, and they can't easily establish what it would cost to rebuild it if it were destroyed. These aren't unreasonable concerns — but they result in most mainstream insurers declining owner-built tiny homes outright.

What Specialist Insurers Look For

Specialist insurers take a more nuanced approach. Rather than requiring formal compliance documentation, they'll consider: the owner-builder's skills, experience, and background (a qualified tradesperson building their own home is viewed very differently from a first-time builder), the quality of materials used and documented sourcing, whether any Licensed Building Practitioners (LBPs) were engaged for any aspect of the build, any independent inspections or certifications obtained during the build, and photographic records of the construction process.

Documentation Makes a Significant Difference

If you're planning to insure a DIY-built tiny home, the most valuable thing you can do is maintain thorough documentation throughout the build:

- Photographs at each stage of construction, particularly showing framing, insulation, and waterproofing before being enclosed

- Receipts and specifications for all major materials

- Any engineering assessments or sign-offs obtained

- Records of any licensed trades involvement (electrical, plumbing)

- Invoices or costings that help establish replacement value

This documentation serves two purposes: it helps the insurer assess and accept the risk, and it helps establish the sum insured accurately.

The January 2026 Building Consent Exemption

Under regulations that came into effect in January 2026, new homes under 70m² no longer require building consent if they meet certain criteria (single-storey, standalone, compliant design, licensed building practitioners, council notification). This is particularly relevant for tiny home builders — and some insurers have confirmed they can consider cover for homes built under this exemption, provided all conditions are met.
