The trust center
Tiny home certification, explained — and honest about what each standard doesn’t do.
Most builders skip certification. That’s why buyers get stuck. This page explains what each standard does and doesn’t do — and how every KYRAX build contract requires third-party certification for your destination market before delivery. One unit, one country’s certification, never both.
Where KYRAX stands, plainly
We're a new builder, and we'd rather over-explain than over-claim. Here's our guarantee: every home we sell is delivered with third-party certification for its destination market — Canadian standards for Canadian deliveries, US standards for US deliveries. It's written into the build contract, and the final payment isn't due until you have a certified home. As our own factory certification program progresses, this page will say so — and you'll be able to verify it in the certifier's public directory, which is exactly how you should check ANY builder's claims.
United States — by product class
Each product class has its own pathway. Per-build certification cost is carried inside the unit price for opportunistic orders — no surprise line items.
RVIA · NOAH
RVIA certification to NFPA 1192 / ANSI A119.5; NOAH adds per-build structural and energy inspection to IRC/NEC/NFPA — recognized by US lenders and insurers. NHTSA/DOT road-legal with VIN.
Doesn't: create a dwelling permit.
ANSI A119.5
The recreational park trailer standard, certified via RVIA or a third party such as RADCO.
Doesn't: serve as a primary-residence path in most jurisdictions.
IBC / IRC + Appendix Q
Built to IBC/IRC 2021 and ICC/MBI 1200/1205/1210 off-site standards. Appendix Q covers tiny houses under 400 sq ft. State program insignia by approved agencies; IIBC reciprocity across member states.
Doesn't: apply uniformly — Appendix Q adoption varies by jurisdiction, some as late as 2027. Permittable claims are destination-checked, always.
HUD Code
24 CFR Part 3280, requiring DAPIA design approval and IPIA production inspection — a pathway KYRAX pursues only if the volume case justifies it. Listed here for completeness, not as a promise.
One certifier, both sides of the border
ICC NTA is SCC-accredited for CSA A277 and certifies US IBC/IRC modular — with PFS-TECO and RADCO also working in both countries. One inspection relationship bridges both pathways. That’s why KYRAX can write third-party certification for wherever you place it into every build contract.

Home certification vs road-legal — two different things
RVIA and NOAH certify the home. NHTSA and CMVSS certify the trailer under it.
Four marks, four different jobs. Here is each one in plain language — and which combination a single unit will carry at delivery, depending on where it’s going.
RVIA
RV Industry Association certification. Verifies the factory builds to NFPA 1192 / ANSI A119.5 — checked by random inspections roughly quarterly. Factory-level, not every unit.
Inspection depth — factory sample
NOAH
National Organization of Alternative Housing. Third-party certification of a specific build — remote video inspection at five build stages, to ANSI A119.5 plus IRC, NEC, and NFPA. Recognized by US lenders and insurers.
Inspection depth — per build, five stages
NHTSA
US highway safety compliance — makes the trailer road-legal to tow in the United States, with VIN. Says nothing about the home on top; that's RVIA or NOAH's job.
CMVSS · 7D1
Canada Motor Vehicle Safety Standards, Transport Canada. The National Safety Mark (7D1) makes the trailer road-legal to tow in Canada — the Canadian counterpart to NHTSA.
What your contract requires at delivery
Delivered to the US: designed to ANSI A119.5 / NOAH inspection standards, with NHTSA compliance and a VIN making the trailer road-legal. Third-party certification for the US is written into the contract and confirmed before delivery.
One home, one country's certification — we never mix them, and it's confirmed before you take delivery.
Not sure which standard your situation needs? That’s the first thing we sort out.
