Blaine County, Idaho Opens Doors For Tiny Houses On Wheels

Blaine County, Idaho Opens Doors For Tiny Houses On Wheels

Robin Butler with NOAH just shared Blaine County, Idaho ordinance NO. 2022-03 with me that is breaking news for the tiny house industry. This is a county that clearly sees that tiny homes on wheels are a viable housing solution for attainable and affordable housing. County Commissioner Dick Fosbury is a champion for tiny house and we appreciate his hard work on this endeavor and all the advocates involved.

NOAH Endorses Potential ASTM Standards

A Message From Robin Butler:Why ASTM?

Ever since Noah came into the tiny house industry in 2015, we have been using Standards and Codes that did not quite fit. Because of the wheels, the I Codes were passed over, and the RV standards (NFPA 1192 and ANSI 119.5) were what most builders, jurisdictions and industry proponents opted for. Appendix Q came into the 2018 IRC but again left out the wheels or movability of Tiny Homes. Since the majority of the tiny home owners were living full time in their home, the RV Standards seemed insufficient for items like structural and energy standards.

In addition the homes have tiny home unique issues. They very small, well insulated and with better windows and are subject to tiny home specific moisture issues. And since they potentially move more than once in their life time, they must be able to be “unplaced” and make trips across our highways.

The need for tiny home specific standards and codes are real. The effort to create a committee through ASTM has, in my opinion, has gotten the most traction and has the best potential for meeting these needs in a timely manner.
