Summary
Under Florida Statutes Section 553.883, a repair or Florida Building Code "Level 1" alteration to a one- or two-family home or townhome in unincorporated Seminole County lets the owner install a smoke alarm powered by a sealed 10-year battery instead of rewiring for a hardwired alarm. Any battery alarm installed or replaced by that work must run on a nonremovable, nonreplaceable 10-year battery, subject to exceptions for monitored and multi-sensor units.
553.883 Smoke alarms in one-family and two-family dwellings and townhomes.—One-family and two-family dwellings and townhomes undergoing a repair, or a level 1 alteration as defined in the Florida Building Code, may use smoke alarms powered by 10-year nonremovable, nonreplaceable batteries in lieu of retrofitting such dwelling with smoke alarms powered by the dwelling's electrical system. 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. The battery requirements of this section do not apply to a fire alarm, smoke detector, smoke alarm, or ancillary component that is electronically connected as a part of a centrally monitored or supervised alarm system; that uses a low-power, radio frequency wireless communication signal; or that contains multiple sensors, such as a smoke alarm combined with a carbon monoxide alarm or other multisensor devices, and is approved and listed by a nationally recognized testing laboratory.
Full Breakdown
883, part of the Florida Building Code (Chapter 553, Part IV) that Seminole County applies to construction work in the unincorporated area, sets a battery standard instead of requiring a full hardwired retrofit. " Three categories are carved out of the battery mandate: alarms wired into a centrally monitored or supervised alarm system, alarms that interconnect with other alarms over a low-power wireless signal, and combination units, such as a smoke and carbon-monoxide alarm, listed by a nationally recognized testing laboratory. Seminole County folds this construction-code standard into its property maintenance enforcement. 5(c)(5) names the Development Services Director, Building Official, Fire Marshal and Code Enforcement Division Manager as the "code official(s)" who administer that requirement. 883.
Violations & Fines
A violation of the adopted maintenance and building-compliance code is a strict-liability offense under County Code Section 95.5(c)(13). The County prosecutes through the Code Enforcement Board or Special Magistrate, which may impose a daily fine for noncompliance, order abatement, or route the matter to a civil code enforcement citation or an independent court action; unpaid costs, interest, administrative expense and attorney's fees may be recorded as a lien on the property under Chapters 95 and 168 of the County Code.
