Straight answers
Does a tiny home need certification to be insured?
Certification is what gives an underwriter a third-party record of how the home was built, and without one the file rests on the owner's word. The two bodies used in the US are RVIA, whose adopted standards are NFPA 1192 for recreational vehicles and ANSI/RVIA A119.5 for park model RVs, and NOAH, which inspects per build. The detail almost nobody is told is that NOAH publishes two different standards, so “NOAH certified” on its own does not say which one a home was built to, and the gap between them is not cosmetic.

01 — The longer answer
Not every certification is the same standard
NOAH+ and NOAH Dwelling are not equivalent
From NOAH's own published comparison: the NOAH+ standard sets floor, wall and ceiling insulation at R13, R13 and R19, requires double-pane windows, does not require arc-fault breakers or tamper-resistant receptacles, and takes an egress window opening of 24 inches wide by 17 inches high. The NOAH Dwelling standard sets R19, R13 and R30, requires a window U-factor of 0.32 or lower, requires arc-fault breakers, tamper-resistant receptacles and three-way switching at the top and bottom of loft stairs, and requires an egress opening of 5.0 square feet on the main floor and 5.7 square feet from a raised floor or loft. Both require hard-wired smoke detection and a fire extinguisher.
Why that difference is worth a question
Those are the items that describe how a home performs in winter and how someone gets out of a loft in a fire. A buyer comparing two certified homes is comparing two different builds, and the certificate alone will not tell them which. Ask which NOAH standard a home was inspected against, and ask for the certificate rather than a logo on a brochure.
What accreditation adds on top
NOAH publishes an accreditation certificate and scope as an ISO/IEC 17020 inspection body through ANAB, the ANSI National Accreditation Board, hosted on ANAB's own directory. That is a different class of assurance from a self-declared badge: it means the inspection body itself has been assessed against an international standard for how it conducts inspections. RVIA operates differently, as a membership programme in which manufacturers pledge in writing to build to the adopted standards and accept unannounced plant inspections, with membership revocable for failure to comply.
The questions to take to a builder
Which standard was this home certified against, who performed the inspection and are they accredited, at what stages was it inspected, and can I see the certificate before I pay a deposit. A builder who cannot answer those quickly is telling you something. So is one who answers with a logo.
Certification is a construction record, not a placement permit and not an insurance policy. It does not decide whether your municipality will let the home sit on your lot, which is zoning, and it does not bind any carrier to write you a policy. It is the evidence the other two conversations run on.
