Tiny home rules in Mount Vernon, NY — 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.
Mount Vernon has no tiny-home-specific ordinance. Any permanent tiny house must meet NYS Uniform Code minimums, zoning dwelling definitions, and all setback/coverage rules.
New York does not have a dedicated tiny-home statute; the NYS Uniform Code (2020) incorporates IRC Appendix AQ for houses 400 sq ft or less but still requires standard residential systems (foundation, egress, sanitation, heating). Mount Vernon's Zoning Ordinance defines 'dwelling' and does not recognize tiny houses on wheels (THOWs) as permanent residences. A site-built tiny home on a foundation would need to comply with the zone's minimum dwelling size, setbacks, and lot coverage, and a THOW is treated as a vehicle/RV and not a permitted dwelling.
Zoning violation notice; removal order for unlawfully occupied THOW; fines per City Code.
