Tiny home rules in Bronx County, 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.
Tiny homes on foundations are not a recognized building type under the NYC Zoning Resolution. Minimum unit sizes and full Building Code compliance apply, which effectively rules out most tiny-house models in The Bronx. Tiny houses on wheels are treated as RVs and cannot be used as permanent dwellings.
NYC Housing Maintenance Code 27-2075 sets minimum room sizes: a legal dwelling unit must have a living room of at least 150 sq ft and the unit itself must have a total floor area that meets zoning minimums, typically at least 400 sq ft. NYC has not adopted Appendix Q of the IRC for tiny houses. Tiny homes on wheels cannot be used as permanent residences under Admin Code 28-101 because they are not permitted structures with a C of O. Parking a tiny-house trailer on a residential lot as a dwelling is a violation.
