Idaho tiny home laws: where you can legally park or place one

First, let's get the most important distinction out of the way. Idaho's state government sorts tiny homes into two completely different categories, and which one you fall into decides everything else about where you can put it.
On wheels, it's an RV
If your tiny home stays on its chassis and wheels, such as a park model tiny home, the State of Idaho classifies it as a Recreational Vehicle. It's regulated by the Idaho Transportation Department rather than local building code, and you'll title and register it the same way you would a travel trailer. Because RVs are meant for temporary or recreational use, living in one full time on private land takes specific permission from your county or city.
On a foundation, it's a home
Take the wheels off and set your tiny home on a permanent foundation, and it becomes real property, treated like any traditional site-built house. Idaho has adopted the 2018 International Residential Code, including Appendix Q, which covers the specifics for homes under 400 square feet, like loft ceiling heights and ladder access. Built to this code, your home can go anywhere a single-family house is allowed.
The takeaway: a tiny home on wheels finds its legal spot through your county's zoning ordinance. A tiny home on a foundation finds its legal spot through the building code.

Frequently asked questions
Are tiny homes on wheels legal in Idaho?
Yes, though it depends on your county rather than a single statewide rule. The state classifies them as RVs, and your county or city decides where and how they can be used as a full-time residence.
Can I place a Snake River Tiny Homes model on my own land?
Yes, in counties that allow it. Blaine, Jefferson, and Bonner counties currently have a confirmed path for certified park model tiny homes as accessory dwelling units or permanent recreational vehicle dwelling units.
Does a tiny home need to be certified to qualify?
Yes in every county with a confirmed path so far, and every Snake River Tiny Homes model already carries NOAH+ certification for exactly this reason.
