Tiny home rules in Mahwah, NJ — 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 in Bergen County must comply with the New Jersey Uniform Construction Code and local minimum dwelling size requirements. Most Bergen municipalities effectively prohibit traditional tiny homes through minimum square footage standards.
New Jersey enforces the Uniform Construction Code (N.J.A.C. 5:23), which adopts the IRC including Appendix Q for tiny houses 400 square feet or smaller. However, municipal zoning typically requires a minimum dwelling size of 600 to 1,200 square feet in Bergen County, making most ground-mounted tiny homes non-conforming. Tiny homes on wheels are classified as recreational vehicles or trailers under N.J.S.A. 39:3-4 and cannot be used as permanent dwellings. Bergen County does not have a county-level tiny home ordinance. Property owners exploring tiny homes should request a zoning interpretation from their municipality before purchasing land or a unit.
Living in a non-conforming tiny home or RV as a residence triggers municipal zoning violations, eviction orders, and fines that can exceed $1,000 per day.
