Smoke alarms in Florida rentals: what landlords and tenants are responsible for

Suppose a manager is turning over a rented duplex. The outgoing tenant pulled the battery from the hallway alarm months ago because it chirped during cooking, and nobody has tested the alarm in the other unit since the last lease began. Before the new tenants get keys, Florida law has something to say about both units, and so does the local fire official.

What does section 83.51 require for smoke alarms?

For single-family homes and duplexes, a specific duty. Section 83.51 says that, unless otherwise agreed in writing, at the commencement of the tenancy of a single-family home or duplex the landlord "shall install working smoke detection devices." The statute defines a smoke detection device as an electrical or battery-operated device that detects visible or invisible particles of combustion and is listed by Underwriters Laboratories, Factory Mutual Laboratories or another nationally recognized testing laboratory.

The same section requires every landlord, whatever the building, to comply with the requirements of applicable building, housing and health codes. Where that general duty is the same as or greater than a duty in the specific list, the general duty controls, and in a single-family home or duplex the code obligations can be altered or modified in writing. A tenant also cannot raise the landlord's failure under the specific list, smoke detectors included, as a defense to an action for possession under section 83.59. Our guide to what Florida law requires landlords to repair covers the rest of the section.

The statute names a moment: the start of the tenancy. In a single-family home or duplex, each new lease begins with working detectors, which makes the move-in inspection the natural place to test them and write the result down.

What does the Florida Fire Prevention Code require?

The building-by-building answer comes from the local fire official. Under rule 69A-60.002 of the Florida Administrative Code, the Florida Fire Prevention Code is the minimum fire prevention code deemed adopted by every municipality, county and special district with firesafety responsibilities, and it applies to every building and structure in the state, apart from two listed groups covered by other firesafety standards. The code consists of NFPA 1, the Fire Code, and NFPA 101, the Life Safety Code, both in their Florida 2021 editions, along with the standards they reference. Local governments may supplement it with more stringent standards. Transient public lodging establishments have their own uniform fire safety standards, chapter 69A-43, which the rule also makes part of the code.

The State Fire Marshal's Florida Fire Prevention Code page fills in the rest. The code is adopted every three years, as chapter 633.202 requires, and the local fire official in each county, municipality and special fire district enforces it; some communities add local amendments. The 8th edition took effect on December 31, 2023, and a read-only copy is online with a free NFPA registration. The page also lists adoption proceedings for a 9th edition, dated 2026, so confirm which edition is in force when you check. For a question about a specific building, the State Fire Marshal's advice is to contact your local fire official.

For an apartment building, then, section 83.51's specific detector rule does not apply, and the requirements to check are the codes.

When must a smoke alarm have a 10-year sealed battery?

When a battery alarm is replaced as part of a level 1 alteration. Section 553.883 lets one-family and two-family dwellings and townhomes undergoing a repair, or a level 1 alteration as the Florida Building Code defines it, use smoke alarms powered by 10-year nonremovable, nonreplaceable batteries instead of being retrofitted with alarms powered by the electrical system. A battery-powered alarm that is newly installed, or that replaces an existing battery-powered alarm, as a result of a level 1 alteration must run on a nonremovable, nonreplaceable battery that powers it for at least 10 years.

The battery rule does not apply to alarms connected to a centrally monitored or supervised alarm system, to alarms that use a low-power radio frequency wireless signal, or to listed multisensor devices such as a combination smoke and carbon monoxide alarm.

Suppose a bathroom remodel in a rented townhome counts as a level 1 alteration, and the old battery alarm outside the bedrooms is replaced as part of it. The replacement needs a sealed 10-year battery unless it is one of the excepted types. A battery that cannot be removed is also one a tenant cannot pull out.

Are carbon monoxide alarms required too?

In newer buildings with a source of carbon monoxide. Section 553.885 requires a building or addition constructed on or after July 1, 2008, that has a fossil-fuel-burning heater or appliance, a fireplace, an attached garage or another feature that emits carbon monoxide, to have an approved operational carbon monoxide alarm within 10 feet of each room used for sleeping, or wherever the Florida Building Code requires. A hard-wired or battery-powered alarm, or a combination smoke and carbon monoxide alarm, satisfies it. The section does not apply to existing buildings undergoing alterations or repairs unless the alteration is an addition.

What are the tenant's responsibilities?

Section 83.52 does not mention smoke alarms by name, but three of its duties reach them. A tenant must comply with all obligations that applicable building, housing and health codes place on tenants; use and operate the unit's electrical and other facilities in a reasonable manner; and not destroy, deface, damage, impair or remove any part of the premises or property belonging to the landlord, or let anyone else do so. Section 83.51 adds that the landlord is not responsible under it for conditions created by the negligent or wrongful act of the tenant, a member of the tenant's family or a guest.

Because the statute is general, the lease is where the routine work gets assigned: who changes batteries in units with replaceable ones, how fast a tenant reports a chirping or missing alarm, and how often the manager tests. Record each test in the move-in and move-out inspection notes. Our make-ready checklist includes a smoke alarm test with the rest of the turnover.
