What Blaine County allows
Blaine County was among the first counties in Idaho to formally address tiny homes on wheels, treating a certified unit as its own category rather than folding it into standard recreational vehicle or mobile home rules. A qualifying tiny home on wheels can be placed as an accessory dwelling unit on a residential lot, provided the unit and its siting meet the standards below.
- Unit is certified to ANSI A119.5 and carries NOAH+ certification
- Unit is registered with the Idaho Transportation Department and passes third party inspection
- Factory fabricated porches and decks under 18 inches in height are allowed; sheds and lean-tos are not
- Lot size supports the intended pathway: 2 to 5 acres for a by right placement, 1 to 2 acres if pursuing a conditional use permit
How the process generally works
- Confirm your lot with the county Call or visit Blaine County Planning and Zoning to confirm your parcel's acreage, zoning district, and whether it qualifies by right or needs a conditional use permit.
- Choose a certified model Every Snake River Tiny Homes model already carries NOAH+ certification and meets Blaine County's cold climate insulation and window standards through our Extreme Weather Package.
- Submit for accessory dwelling unit approval The county reviews the placement against the Title 9, Chapter 3, Section 11 standards, including setbacks and the general accessory dwelling unit rules that apply alongside the tiny home on wheels provisions.
- Complete registration and third party inspection Register the unit with the Idaho Transportation Department and schedule the required third party inspection before or at placement.
- Finalize siting Install skirting, confirm utility connections, and keep documentation of certification and inspection on hand for the county's records.
