Boulder City, NV Accessory Structures: Tiny Homes (2026)

Boulder City regulates tiny homes based on their construction type. Foundation-built tiny homes that meet full International Residential Code requirements including minimum ceiling heights, egress, and energy code compliance are permitted as primary dwellings or accessory dwelling units where allowed by zoning. Appendix Q of the IRC, which permits tiny houses under 400 square feet with reduced loft and stair requirements, has been partially adopted. Tiny homes on wheels (THOWs) are classified as recreational vehicles and are generally not permitted as permanent dwellings in residential zones, though they may be allowed in licensed RV parks for limited stays. Minimum dwelling size requirements in some zones may still apply, typically 600 to 800 square feet for primary residences. ADU regulations permit smaller units, often 400 to 900 square feet. Utility connections, setbacks, parking, and design standards apply. Contact the Planning Department to verify current zoning rules before purchasing or constructing a tiny home.
