Does Florida require carbon monoxide alarms in Space Coast homes?

Florida Statute 553.885 requires a carbon monoxide alarm within 10 feet of each bedroom in buildings built on or after July 1, 2008 with a fuel-burning appliance, fireplace, or attached garage. This applies in Brevard County.

If you are buying or selling a home in Melbourne, Viera, Merritt Island, or anywhere else on Florida's Space Coast, the alarms on the ceiling are easy to ignore until the inspector points at them. Two state statutes shape what is expected: one covers carbon monoxide alarms, the other covers smoke alarms when work is done on a home.

I am a REALTOR, not an attorney or a fire marshal, so treat this as a plain-English reading of the statute text. The links below go to the Florida Senate's statute pages so you can read the exact wording yourself, and your inspector or the local fire official can confirm what applies to a specific house.

What does the Florida carbon monoxide alarm statute actually say?

Section 553.885 is written around new buildings and additions. It covers every separate 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 gives off carbon monoxide as a byproduct of combustion. Hospitals, inpatient hospice facilities, and licensed nursing homes follow a separate rule.

For a typical house on the Space Coast, the requirement is an approved, operational carbon monoxide alarm within 10 feet of each room used for sleeping. The statute allows a hard-wired or battery-powered carbon monoxide alarm, or a hard-wired or battery-powered combination carbon monoxide and smoke alarm.

Question What the statute text says
Which buildings? Buildings or additions constructed on or after July 1, 2008 with a fuel-burning feature, fireplace, or attached garage
Where does the alarm go? Within 10 feet of each room used for sleeping, or where the Florida Building Code requires
Power source? Hard-wired or battery-powered, including combination CO and smoke alarms
Older homes that are only repaired? The statute says it does not apply to existing buildings undergoing alterations or repairs unless the work is an addition

Does a Brevard County home built before 2008 need one?

The statute does not, on its own wording, require a carbon monoxide alarm in an existing home that is only being altered or repaired. It reaches new buildings and additions. Many Space Coast homes in older Melbourne, Merritt Island, and beachside neighborhoods were built well before 2008, so the statute is not the whole picture for them.

Lenders, insurers, and buyers may still ask for working alarms, and a carbon monoxide alarm is inexpensive protection in any home with a gas range, gas water heater, fireplace, or garage that connects to the living space. Whether a specific permit or inspection triggers more requirements depends on the Florida Building Code and the local building department, so ask the department that issued the permit.

What do smoke alarms have to do with a roof or kitchen permit?

Section 553.883 covers smoke alarms in one-family and two-family dwellings and townhomes that are undergoing a repair or a level 1 alteration, as the Florida Building Code defines those terms. In those homes, the owner may use smoke alarms powered by 10-year nonremovable, nonreplaceable batteries instead of retrofitting alarms wired into the home's electrical system.

The same section says a battery-powered smoke alarm that is newly installed, or that replaces an existing battery-powered alarm as part of a level 1 alteration, must be powered by a nonremovable, nonreplaceable battery that lasts at least 10 years. It lists exclusions, including alarms tied into a centrally monitored system, alarms using a low-power radio frequency wireless signal, and multisensor devices such as a combined smoke and carbon monoxide alarm, as long as the device is approved and listed by a nationally recognized testing laboratory.

The section does not say every existing home needs 10-year batteries. The 10-year battery language appears in the context of repairs and level 1 alterations.

What should Space Coast sellers do before listing?

  • Press the test button on every smoke and carbon monoxide alarm and replace any that do not sound.
  • Look for the manufacture or replace-by date printed on each unit and follow the manufacturer's instructions.
  • If you added a room, garage, or addition, ask your contractor which alarms were installed under the permit.
  • Keep receipts or permit paperwork for any alarm work so you can answer buyer questions quickly.

Working alarms are a small detail that keeps an inspection report short. Buyers across Brevard County read every line of those reports.

What should Space Coast buyers check?

Walk the home and note where the alarms are. Count the bedrooms and check whether a carbon monoxide alarm sits near each sleeping area, especially if the home has an attached garage, a gas appliance, or a fireplace. Ask your inspector to test them during the inspection, and ask the seller for permit records if the home has an addition.

To read the exact wording, see the text of Florida Statute 553.885 and the text of Florida Statute 553.883. Both are the 2025 compilation, so check the current statute pages for any later changes. Your local building department in Brevard County can confirm what applies to a permitted project, and the Brevard County government website is the place to start.

FAQ

Is a combination smoke and carbon monoxide alarm acceptable in Florida?

Section 553.885 says a hard-wired or battery-powered combination carbon monoxide and smoke alarm satisfies the carbon monoxide requirement for covered buildings. Section 553.883 also lists multisensor devices as excluded from its battery rule when they are approved and listed by a nationally recognized testing laboratory.

Does Florida law require alarm upgrades when I sell my home?

Neither statute, as written, creates a sale-triggered requirement. Section 553.885 centers on new construction and additions, and section 553.883 centers on repairs and level 1 alterations. Your contract, lender, or insurer may add its own expectations.

Who can confirm the rules for my specific house?

The building department that issued your permit, your home inspector, and a Florida attorney can each speak to a specific property. I can point you in the right direction, but I do not give legal advice.
