Full Breakdown
Section 6-4 of the Gainesville Code of Ordinances applies to tiny houses used as single dwelling units. A tiny house is a dwelling of 400 square feet (37 square meters) or less in floor area, and lofts do not count toward that figure. Everything in the Florida Building Code still applies unless § 6-4 says otherwise, and Chapter 6 is enforced by a building official designated by the city manager under § 6-3.
Ceiling heights are the first departure from the base code. Habitable space and hallways need at least six feet eight inches (2032 mm). Bathrooms, toilet rooms and kitchens need at least six feet four inches (1930 mm). Beams, girders, ducts and lighting cannot hang below those heights. Lofts are exempt from the six-foot-eight minimum.
A loft is a floor level more than 30 inches above the main floor, open to the main floor on at least one side, with a ceiling under six feet eight inches, used for living or sleeping. A loft used that way needs at least 35 square feet and at least five feet in every horizontal dimension. Sloped-ceiling areas under three feet high do not count toward the 35 square feet, and under a gable roof pitched at 6 in 12 the cutoff is 16 inches. Loft guards on the open side must be at least 36 inches high or half the clear height to the ceiling, whichever is less.
Loft access can be a stairway, ladder, alternating tread device or ships ladder. A loft stairway must be at least 17 inches clear at or above the handrail and 20 inches below it, with 6 feet 2 inches of headroom, risers between 7 and 12 inches, and a landing platform 18 to 22 inches deep and 16 to 18 inches high where the loft ceiling is under 6 feet 2 inches. A ladder needs 12-inch rungs spaced 10 to 14 inches apart, a 200-pound rung rating and a 70 to 80 degree incline.
Tiny houses must also meet Section R310 for emergency escape and rescue openings. A roof access window in a sleeping loft satisfies R310 when the bottom of the opening sits no more than 44 inches above the loft floor and the window meets the R310.2.1 minimum opening area.
The section was adopted by Ord. No. 171056 on December 6, 2018 and is in force today. It sets construction standards only. Under § 6-3, a building permit is required before construction, and any work started without one pays double the permit fee.
Violations & Fines
Under § 6-3(f), a violation of Chapter 6 is declared a public nuisance, and the city may use any enforcement power or penalty available under Florida law or the Gainesville Code, including section 1-9. Starting work before a permit is issued doubles the permit fee and does not prevent prosecution. The building official can suspend or revoke a permit issued on inaccurate information or for work that does not conform to the chapter or the Florida Building Code.
