Full Breakdown
Section 6-4 of the Code of Ordinances applies to tiny houses used as single dwelling units and requires compliance with the Florida Building Code except as modified here. A "tiny house" is defined as a dwelling of 400 square feet or less, excluding lofts. Habitable space and hallways must have ceilings at least six feet eight inches high; bathrooms, toilet rooms, and kitchens need only six feet four inches, and no beam, duct, or light fixture may intrude below those minimums. Lofts used for sleeping or living space must have at least 35 square feet of floor area and be no less than five feet in any horizontal dimension, though sloped-ceiling portions under three feet (or 16 inches under a 6:12 gable) do not count toward that area.
12). Loft guards along open sides must be at least 36 inches tall or half the clear ceiling height, whichever is less. Emergency escape and rescue openings must meet Section R310, though an egress roof access window (skylight) in a sleeping loft satisfies that requirement if its opening bottom sits no more than 44 inches above the loft floor. Because Section 6-4 sits inside Article I of Chapter 6, the general building-code administration provisions of Section 6-3 govern permitting, inspection, and enforcement for tiny house construction.
Violations & Fines
Tiny houses are treated as building-code work: an owner must obtain a building permit before construction under § 6-3(b). Starting work before the permit issues doubles the required permit fee under § 6-3(c)(1). The city commission has declared any violation of Chapter 6 a public nuisance under § 6-3(f), enforceable with penalties under § 1-9 of the Code. The building official may also suspend or revoke a permit under § 6-3(g) if the tiny house was built in violation of these standards or on inaccurate application information.
