Georgia Restaurant Fire Alarm Code: 2026 Compliance Guide

If you own or operate a restaurant in Georgia, the rules that govern your fire alarm system changed more recently than most owners realize. The Georgia State Fire Marshal’s Office adopted the 2024 edition of NFPA 101 (Life Safety Code) effective May 27, 2025, and the 2024 International Building Code took effect statewide on January 1, 2026. If your last code review predates those dates, your restaurant may be operating under outdated assumptions – and a single failed inspection can shut you down on a Friday night.

This guide walks through what Georgia restaurant owners actually need to know in 2026: how your occupancy classification determines what’s required, when a fire alarm system is mandatory, how kitchen hood suppression has to tie into that alarm, and the inspection schedule that keeps you out of trouble.

The Code Framework: What Georgia Adopts and Enforces

Georgia doesn’t write its fire code from scratch. The State Fire Marshal’s Office, under the Office of the Commissioner of Insurance and Safety Fire, adopts national model codes and modifies them through Chapter 120-3-3 of the Georgia Rules and Regulations. For restaurants, four documents do most of the work:

• NFPA 101, Life Safety Code (2024 edition) sets occupancy classifications, egress, and fire alarm triggers.
• International Fire Code, 2024 edition (with Georgia amendments) governs sprinkler thresholds, fire alarm installation, and inspection mandates.
• NFPA 72, National Fire Alarm and Signaling Code the technical bible for how the alarm itself is designed, installed, and tested.
• NFPA 96, Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations covers the kitchen hood, the wet chemical suppression system, and the required interconnection with the fire alarm.

Local AHJs (Authorities Having Jurisdiction) like the Cobb County Fire Marshal, Atlanta Fire Rescue, or your city building official enforce these codes and can add stricter local amendments. When in doubt, the AHJ is the final word.

Step 1: Figure Out Your Occupancy Classification

Everything starts here. Under NFPA 101, a restaurant’s classification depends on its occupant load, and the 50-person line is the dividing one:

• Fewer than 50 occupants: Typically classified as a business or mercantile occupancy (less stringent fire alarm requirements).
• 50 or more occupants: Classified as an Assembly Occupancy specifically Group A-2 under the IBC, which covers spaces used for food and drink consumption.

Occupant load isn’t a guess. It’s calculated from Table 7.3.1.2 of NFPA 101, dividing your floor area by the per-person factor for each space type (15 net square feet per person for unconcentrated dining tables and chairs, 7 net for concentrated seating with non-fixed chairs, 100 gross for the kitchen, and so on). A 1,500-square-foot dining room with tables and chairs has a calculated occupant load of 100 even if you only ever seat 60 at a time. The code uses the calculated number, not your average Friday count.

This matters because Group A-2 carries the strictest sprinkler triggers in the entire assembly category, and it changes what your fire alarm has to do.

Step 2: When a Fire Alarm System Is Required

For a Georgia restaurant classified as Group A-2 (50+ occupants), NFPA 101 requires a fire alarm system when any one of these conditions exists:

1. The total assembly occupant load is 300 or more, or
2. 100 or more occupants are located above or below the level of exit discharge (think rooftop bars, basement speakeasies, or mezzanine seating), or
3. The Life Safety Code’s general arrangement clause applies meaning the building is laid out such that fire itself wouldn’t reliably alert all occupants (long corridors, partitioned private dining rooms, separate banquet halls).

Even if your restaurant falls below those numbers, any building with a sprinkler system must have a fire alarm system to monitor sprinkler waterflow and transmit the signal to a supervising station. That single requirement catches more restaurants than the occupant-load triggers do.

When a fire alarm is required, NFPA 72 dictates the design: manual pull stations at every exit, audible/visible notification appliances throughout occupied spaces (horns and strobes — strobes are not optional in occupied areas), smoke or heat detection where required by the AHJ, and a means of transmitting the alarm to a UL-listed central monitoring station 24/7. (Learn more about how monitoring works.)

Step 3: Sprinkler Requirements Are Stricter Than You Think

Group A-2 sprinkler triggers are unforgiving. Under IBC §903.2.1.2, an automatic sprinkler system is required throughout your story and every story between you and the level of exit discharge when any one of these is true:

1. The fire area exceeds 5,000 square feet, or
2. The fire area has an occupant load of 100 or more, or
3. The Group A-2 occupancy is on a floor other than the level of exit discharge.

That 100-occupant threshold is half what triggers sprinklers in a Group A-3 (lecture halls, libraries) or A-4 (arenas) space. The reason is straightforward: dining rooms have tables, servers, and slow egress paths, so the model code compensates with earlier sprinkler intervention.

Once sprinklers are installed, NFPA 13 governs design and NFPA 72 takes over for the waterflow alarm your fire alarm panel must monitor every waterflow switch and tamper switch on the sprinkler system, and any signal must transmit to the monitoring station within seconds.

Step 4: Kitchen Hood Suppression and the Fire Alarm Interconnect

Most cooking-related fire incidents in restaurants start at the cookline, which is why NFPA 96 is so prescriptive. Every commercial cooking appliance that produces grease-laden vapors (fryers, ranges, charbroilers, woks, salamanders) must be protected by a UL 300-listed wet chemical suppression system inside a Type I hood. Pre-UL 300 dry chemical systems are not grandfathered; if your restaurant still has one, it will not pass inspection.

When the hood suppression system activates, NFPA 96 §8.7 requires several things to happen simultaneously and automatically:

• The wet chemical agent discharges over the cookline and into the hood.
• All fuel and electrical power to the protected appliances shuts off.
• A signal is transmitted to the building fire alarm system per NFPA 72.

That last item is what most owners miss. The hood suppression system isn’t allowed to operate as an island. It must be wired to the fire alarm control panel through a supervised interface typically a contact closure that initiates a general alarm and dispatches the fire department through your monitoring station. If that interconnect is missing, broken, or wired to a panel that no longer communicates with the monitoring station (a common problem on systems with retired POTS phone lines), you’re out of compliance the moment the inspector tests it.

You also need a Class K fire extinguisher within 30 feet of every cooking appliance, semiannual professional inspection of the suppression system, and replacement of metal-alloy fusible links every six months.

Step 5: Inspection and Testing Schedule

NFPA 72 sets the testing baseline; NFPA 96 layers on the kitchen-specific items. Here’s the schedule a Georgia restaurant should expect:

• Daily/weekly visual checks by staff control panel status, no trouble lights, no obstructed pull stations or notification appliances.
• Semiannual kitchen hood suppression system service (nozzle condition, agent level, manual pull station, gas shutoff valve, fire alarm interconnect, fusible link replacement).
• Quarterly to annually kitchen exhaust hood and duct cleaning, frequency determined by NFPA 96 Table 11.4 based on cooking volume.
• Annual full fire alarm system inspection and test per NFPA 72 (every initiating device, every notification appliance, battery load test, communication path verification, sensitivity test for smoke detectors).
• Annual sprinkler system inspection per NFPA 25.

Documentation matters as much as the work itself. Inspectors will ask to see your inspection reports, and most jurisdictions require records on-site for at least three years. (Grice Systems handles full inspection and testing for Georgia restaurants.)

Common Code Violations Inspectors Flag in Georgia Restaurants

After installing and inspecting fire alarm systems for restaurants across Georgia for years, the same handful of issues come up over and over:

• Hood suppression system not interconnected to the fire alarm panel (or the interconnect was disabled during a remodel and never restored).
• Pre-UL 300 dry chemical suppression systems still in service.
• Sprinkler waterflow not monitored, or monitored to a phone line that no longer works.
• Strobe notification appliances missing in restrooms, kitchens, or private dining rooms.
• Manual pull stations blocked by furniture, decor, or signage.
• Expired fire alarm batteries (5–7 year replacement cycle).
• Inspection reports missing or out of date.
• Smoke detectors installed in kitchens or directly above cooking equipment (they should be heat detectors smoke detectors will nuisance-trip constantly).

Any one of these can result in a failed inspection, fines, or a temporary closure order from the fire marshal.

What to Do Next

If your restaurant is approaching its annual inspection, opening a new location, renovating, or expanding seating capacity in a way that pushes you past the 50, 100, or 300 occupant thresholds, now is the time to get ahead of it. A pre-inspection walkthrough by a licensed commercial fire alarm contractor is far cheaper than a failed inspection and an emergency retrofit.

Grice Systems designs, installs, inspects, and monitors fire alarm and detection systems for restaurants across Georgia — from single-location independent operators to multi-unit franchise groups. We work directly with your kitchen hood contractor and sprinkler company to make sure every system talks to every other system the way the code requires.
