Every state's current tiny-home-on-wheels and ADU rules, verified and dated — pick a state below, or use the interactive tool to check an address directly.
Zoning for tiny homes is set locally, not federally — so "is it legal" always depends on which state, and usually which city or county, you're asking about. Tiny Homes Zoning tracks the current statewide picture for all 50 states: whether there's a statewide ADU mandate, how tiny homes on wheels are classified, and what to check before buying land or starting a build. Every entry below is dated and sourced; none of it is legal advice.
