Tiny home rules in Babylon, 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 must meet NY Uniform Code full residential requirements. Tiny homes on wheels (THOWs) are treated as RVs and cannot be used as permanent dwellings in Babylon residential zones. Minimum dwelling unit size typically 400-500 sq ft in Babylon zoning. No formal tiny home ordinance exists.
NY Residential Code adopted Appendix Q allowing tiny homes under 400 sq ft on foundations with reduced requirements (loft sleeping, ladders, emergency egress), but Babylon has not locally adopted Appendix Q. THOWs fall under RV rules (Chapter 189) prohibiting permanent residential occupancy. Zoning districts set minimum lot area and dwelling size that most tiny homes cannot satisfy.
