Summary
Tiny houses built in unincorporated Leon County get their own smoke alarm placement rule. Sec. 5-2.10(f) adds a local subsection, R314.3.2, to the Florida Building Code - Residential, spelling out exactly where alarms go in a home too small for the standard whole-house layout.
(f)Add to the Florida Building Code, Residential for Tiny House section R314.3.2 as follows: R314.3.2 Location in Tiny Houses. Smoke alarms shall be installed in the following locations: 1.In the Medium & Large units:(a)The additional detector located outside of the bedroom would not be required in the kitchen / living area.2.In the Small units:(a)The detector may be located within 3 feet of the bathroom door.3.All units with separate bedrooms & habitable lofts would have smoke detectors as required by Section 314.

Full Breakdown
Leon County adopted the Florida Building Code and the state Fire Prevention Code wholesale under Sec. 07, so ordinary homes follow FBC-Residential Section 314's alarm rules by reference. Tiny houses, defined at Sec. 10(b) as dwellings of 400 square feet or less in gross floor area (lofts excluded), get an additional locally-drafted subsection because the standard layout does not fit a home that small. Sec. 2, 'Location in Tiny Houses,' directly into the adopted code. It splits requirements by unit size: medium and large tiny house units still need a detector outside each bedroom, but the code drops the usual requirement for an additional unit in the kitchen or living area.
Small units get more flexibility still: the required detector may sit within three feet of the bathroom door rather than in a separate hallway location. Any unit with separate bedrooms or a habitable loft falls back to the full alarm count required generally by Section 314, so a loft used for sleeping needs its own alarm just like a bedroom would. This division applies only outside the City of Tallahassee's limits; Tallahassee runs its own building code process. The rule took effect under Ord. No. 21-01, Section 1, adopted January 26, 2021, alongside the rest of the county's building code amendments.
Violations & Fines
A tiny house that skips the required alarm locations fails its building inspection under the county's general permit process (Sec. 5-1.05) and will not clear the construction plans review the Building Plans Review and Inspection Division runs before signing off. No unit can receive final approval or a certificate of occupancy until the alarms are installed at the locations R314.3.2 specifies; there is no separate fixed-dollar fine written into this subsection.
