New Jersey Uniform Construction Code Applies to Tiny Homes

Under NJSA 52:27D-119 et seq., all permanent dwellings in New Jersey must comply with the Uniform Construction Code, which adopts the International Residential Code. NJ has adopted IRC Appendix Q, providing relaxed standards (lofts, ladders, reduced ceiling heights) for dwellings 400 square feet or less. Tiny homes on wheels are regulated as recreational vehicles and generally cannot be used as permanent residences in residential zones. Local zoning controls minimum dwelling size and where tiny homes may be sited.

Occupying a non-compliant tiny home as a dwelling can result in UCC penalties up to $2,000 per violation and local zoning enforcement, including eviction or removal orders.
