Full Breakdown

New York adopted the International Residential Code with Appendix Q, allowing dwellings 400 square feet or less to use reduced ceiling height, loft, and stair standards. Tiny homes on permanent foundations are regulated as site-built homes; those on wheels are typically classified as RVs and cannot be used as full-time dwellings on residential lots without a certificate of occupancy. Local zoning controls minimum house size and where tiny homes may be placed.

Violations & Penalties

Occupying an uncertified tiny home as a primary residence may trigger orders to vacate and zoning enforcement actions.
