Tiny home rules in Las Vegas, NV — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Las Vegas allows tiny homes only when built to the 2018 IRC with Southern Nevada Amendments on a permanent foundation in a residential zone. Tiny houses on wheels are not recognized as permanent dwellings. Detached ADUs are capped at 1,200 sq ft.
Las Vegas adopts the 2018 IRC and IBC with Southern Nevada Amendments under LVMC Title 16. A site-built tiny home on a permanent foundation is treated as a single-family dwelling and must meet IRC habitability: at least one habitable room of 70 sq ft, ceilings at least 7 feet, plus egress, smoke and CO alarms, and ventilation. Tiny homes on wheels and park-model RVs are not allowed as permanent residences in standard residential zoning and are limited to licensed RV or mobile home parks under LVMC Title 19. When the tiny home is built as an ADU, Nevada AB 283 (2021) caps detached ADUs at 1,200 sq ft including any attached garage. The City has not adopted IRC Appendix Q.
Living in a tiny home on wheels outside a licensed RV or mobile home park is a Title 19 zoning violation. Building a tiny home without permits, or below 70 sq ft or 7 ft ceilings, fails inspection.
