Summary

Florida law (FS 553.883) and the Florida Building Code require smoke alarms in every dwelling. New homes must be hardwired; when replacing a battery unit or doing a level-1 alteration, the new alarm must use a nonremovable 10-year sealed battery.

City-specific rules exist: Winter Haven has its own smoke detectors rules that differ from Polk County's county-level regulations. If you live in Winter Haven, check the city-specific page instead.

A battery-powered smoke alarm that is newly installed or replaces an existing battery-powered smoke alarm as a result of a level 1 alteration must be powered by a nonremovable, nonreplaceable battery that powers the alarm for at least 10 years.

Full Breakdown

Smoke-alarm requirements in Polk County follow statewide Florida law, not a separate county code. FS 553.883 governs smoke alarms in one- and two-family dwellings and townhomes. New construction must have interconnected, hardwired smoke alarms with battery backup per the Florida Building Code, generally installed in each sleeping room, outside each sleeping area, and on every level. For existing homes undergoing a repair or level-1 alteration, a battery-powered smoke alarm that is newly installed or replaces an existing battery-powered alarm must be powered by a nonremovable, nonreplaceable 10-year battery. Alarms should be tested monthly and replaced about every 10 years.

Violations & Fines

Enforced through building-permit inspection and the Florida Fire Prevention Code; landlords/rentals failing to maintain working alarms face code-enforcement action and civil liability.
