Orlando, FL Fire Regulations: Smoke Detectors (2026)

Smoke alarms in Orlando are governed by Florida Statute 553.883, the Florida Building Code Residential R314, and NFPA 72. New single-family and townhome construction, and substantial alterations or additions, must install hard-wired smoke alarms with battery backup, interconnected so that activation of one alarm triggers all alarms, located in every sleeping room, immediately outside each sleeping area (the hallway), and on every story including habitable attics and basements. For existing homes not undergoing major renovation, at least one functioning smoke alarm must be present on every level. Florida Statute 553.883(2) also requires that when an existing battery-only alarm is replaced, the replacement must be a 10-year sealed-battery alarm unless the home has hard-wired alarms. Combination smoke and carbon monoxide alarms are required where fuel-burning appliances or attached garages exist, per FL Statute 553.885. Landlords must provide working alarms at the start of every tenancy under FL Statute 83.51. Alarms expire 10 years from the date of manufacture; tampering or removing alarms can lead to code violations and insurance complications.
