Tiny home rules in Jacksonville, FL — 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 Jacksonville must comply with the Florida Building Code and local zoning under Ch. 656. A tiny home on a permanent foundation is treated as a dwelling unit and must meet all building code requirements including minimum standards. Tiny homes on wheels are classified as recreational vehicles and generally cannot serve as primary residences in residential zones. Mobile and manufactured homes are permitted only in designated zoning districts. ADU (accessory dwelling unit) ordinances may provide additional options.
Tiny home regulations in Jacksonville depend on whether the structure is on a permanent foundation or on wheels. Foundation-based tiny homes are regulated as conventional dwellings or ADUs and must meet all building codes including minimum room sizes, ceiling heights (7 feet minimum), egress windows, and utility connections. Most zones have a minimum dwelling size (often 400–600 sq ft) that may require a variance for smaller units. Tiny homes on wheels (THOWs) are classified as recreational vehicles under Jacksonville's zoning code and generally cannot be used as primary residences in residential zones. Some areas are exploring THOW-friendly zoning amendments. Tiny home communities may be permitted as planned developments. Florida's building code appendices for tiny houses (IRC Appendix Q) may apply where adopted locally.
Occupying a THOW as a primary residence in a non-permitted zone: $100–$500/day zoning violation. Building a tiny home without permits: standard building code violation fines. Minimum size violations: variance required.
