Every commercial building in Georgia is required to have functioning emergency lighting and illuminated exit signs. These are not optional upgrades or suggestions; they are life-safety systems mandated by state-adopted fire and building codes. If you own or manage a business in Lawrenceville, Duluth, Snellville, or anywhere in Gwinnett County, your emergency exit lighting requirements are enforced by local fire marshals, and falling short can result in citations, fines, or forced closure until you correct the problem.
This article breaks down the codes that apply, what your systems need to do, how often you must test them, and the most common issues that trip up Georgia business owners during inspections.
The Codes That Govern Emergency and Exit Lighting in Georgia
Georgia adopts statewide minimum standard codes through the Department of Community Affairs. These include the International Building Code and International Fire Code, both of which reference two critical national standards: NFPA 101 (the Life Safety Code) and NFPA 70 (the National Electrical Code, or NEC). In practical terms, the requirements outlined in those national standards carry the force of law in every Georgia municipality.
NFPA 101 is the primary standard that dictates where emergency lighting and exit signs must be installed, how bright they need to be, and how long they must stay on during a power failure. The NEC, covered under NFPA’s codes and standards for the Life Safety Code, governs the electrical installation itself, including wiring methods, overcurrent protection, and the reliability of backup power sources.
For Georgia business owners, the bottom line is straightforward: both sets of requirements apply to your building, and local inspectors check for compliance with both.
What Your Emergency Lighting and Exit Signs Must Actually Do
Exit Sign Requirements
Every exit door and every point along a path of egress (the route occupants use to leave the building) where the exit is not immediately obvious must have an illuminated exit sign. These signs must be clearly legible, with a minimum luminance of 5 foot-candles on the sign face. They must be connected to a backup power source, either internal batteries or a generator, so they remain lit for at least 90 minutes if normal power fails.
Egress Lighting Requirements
Emergency lighting must illuminate the entire path of egress, including corridors, stairwells, aisles, ramps, and areas where people gather. The floor along the egress path must receive at least 1 foot-candle of illumination when the system activates. By the end of the required 90-minute battery duration, that level can drop to no less than 0.1 foot-candle, but the ratio between the brightest and dimmest spots along the path cannot exceed 40 to 1. This prevents dangerous dark spots that could cause falls or disorientation.
The transfer from normal power to emergency power must happen within 10 seconds. That near-instant switchover is a code requirement, not a design preference. If your system takes longer than that, it does not comply. If your facility is in Atlanta, our emergency electrician in Atlanta team handles this same compliance work.
Monthly and Annual Testing Rules You Cannot Skip
Testing is one of the most commonly cited deficiencies during fire inspections in Gwinnett County, and it is also one of the easiest to get right with a simple routine.
Monthly Functional Test
Every emergency light and exit sign must be tested for at least 30 seconds each month. The purpose of this test is to verify that each unit activates and illuminates when normal power is interrupted. For battery-backed units, this typically means pressing a test button on the fixture. This quick check confirms the lights come on but does not verify full battery capacity.
Annual Full-Duration Test
Once a year, every unit must be tested for the full 90-minute discharge period. The battery is disconnected from its charger and allowed to run until either it sustains illumination for the full 90 minutes or it fails. Units that cannot maintain adequate light output for the full duration need battery replacement or full unit replacement.
Documentation Is Mandatory
NFPA 101 requires written records of every monthly and annual test, along with any repairs or maintenance performed. These records must be kept on the premises and available for review by the authority having jurisdiction, which in most of metro Atlanta means your local fire marshal or building inspector. Missing or incomplete records are a citation item, even if the equipment itself works perfectly. If your business has ever received a code violation notice, you know how disruptive the correction process can be. Our guide to common electrical code violations in Atlanta covers several issues that overlap with emergency lighting compliance.
Battery-Backed Units vs. Generator-Backed Systems
Most small to mid-size commercial properties in the Lawrenceville and greater Gwinnett County area use self-contained, battery-backed emergency lights and exit signs. Each fixture has its own rechargeable battery that activates when it senses a loss of normal power. These units are relatively affordable to install, typically ranging from $250 to $750 or more per fixture including labor and materials, depending on the type of unit and the complexity of the wiring.
Larger commercial buildings, warehouses, and multi-tenant facilities sometimes use a central inverter system or generator-backed emergency lighting. These systems provide backup power from a single source rather than relying on individual batteries in each fixture. They offer easier centralized maintenance and monitoring but involve significantly higher upfront costs, potentially tens of thousands of dollars, and more complex electrical infrastructure.
Several factors drive costs up in metro Atlanta. Older commercial buildings in Lawrenceville, Lilburn, and Duluth may have outdated wiring that does not meet current code, requiring more extensive work during installation. High ceilings, concealed wiring in finished spaces, and hazardous-location ratings for fixtures all add to the price. On the other hand, straightforward installations in accessible, newer buildings with standard fixtures tend to be more economical.
Battery replacement is a recurring maintenance cost. Expect to pay roughly $75 to $200 or more per unit for battery replacement, including labor and proper disposal. Georgia’s hot, humid summers accelerate battery degradation, as high temperatures reduce battery life and frequent storm-related power outages mean more discharge cycles. Humidity can also corrode terminals and connections inside the fixtures, particularly in semi-enclosed areas like loading docks.
Common Citation Items and How to Avoid Them
Fire inspectors across Gwinnett County and DeKalb County focus on emergency and exit lighting during routine inspections. Here are the issues that most frequently result in citations.
Missing or incomplete test records top the list. Even if every fixture in your building works, you will receive a citation if you cannot produce documentation of monthly and annual tests. Keep a logbook or use a digital tracking system, and make sure it is accessible on-site.
Units that illuminate briefly but fail before 90 minutes are another common finding. A fixture that lights up for a few seconds during a power flicker may look fine, but only a full annual discharge test can confirm it will last the required duration. Many business owners skip the annual test because it is time-consuming. That shortcut often leads to a failed inspection.
Incorrect placement or insufficient coverage creates dangerous gaps in illumination along the egress path. This usually happens when a building layout changes, such as adding partitions, rearranging storage, or converting a space to a different use, without updating the emergency lighting plan. A professional assessment ensures that illumination levels meet the 1 foot-candle minimum throughout the path of egress.
Non-functional or dim exit signs are easy to overlook during daily operations but stand out immediately during an inspection. LED exit signs have largely replaced older incandescent and fluorescent models. They last longer, consume less energy, and are less prone to failure, making them a worthwhile upgrade for any business still running older technology.

Why Licensed Electricians Must Handle This Work
Georgia law requires that all commercial electrical work be performed by or under the direct supervision of a contractor holding a valid Electrical Contractor license from the Georgia Construction Industry Licensing Board. This applies to installing new emergency lights, replacing fixtures, adding circuits, troubleshooting failures, and performing battery replacements.
There is virtually no aspect of emergency and exit lighting work in a commercial building that qualifies as a DIY task. Beyond the legal requirement, there are practical safety reasons. Emergency lighting circuits carry shock risk, and faulty battery charging systems or damaged wiring can create fire hazards. Proper installation also requires knowledge of illumination calculations, egress path analysis, and current code requirements, all of which fall outside typical building maintenance skills. OSHA’s standards for exit routes and emergency lighting reinforce that these are workplace safety systems, not cosmetic fixtures.
Attempting this work without a licensed electrician also exposes your business to voided insurance coverage, liability issues, and additional fines on top of any code violations.
Keeping Your Metro Atlanta Business Compliant Year-Round
Emergency and exit lighting compliance is not a one-time project. It is an ongoing responsibility that requires monthly attention, annual testing, and prompt repairs when units fail. Georgia’s storm season, summer heat, and the age of many commercial buildings in Gwinnett County all put extra stress on these systems.
The most effective approach is to establish a relationship with a licensed commercial electrician who can handle your monthly and annual testing, keep your documentation current, and address repairs before they become inspection failures.

Frequently Asked Questions
How often do I need to test my emergency lights and exit signs in Georgia?
Monthly functional tests of at least 30 seconds are required for every emergency light and exit sign. Once a year, a full 90-minute discharge test must be performed to verify that batteries can sustain illumination for the entire required duration. Written records of all tests must be kept on-site and available for fire marshal inspections.
What happens if my business fails an emergency lighting inspection in Gwinnett County?
You will typically receive a citation with a deadline to correct the deficiencies. Depending on the severity, the fire marshal may require re-inspection, impose fines, or in extreme cases restrict occupancy until the problems are resolved. Keeping up with monthly and annual testing, and maintaining proper documentation, is the most reliable way to avoid these situations.
Can I replace emergency light batteries myself, or do I need a licensed electrician?
In a commercial building in Georgia, all electrical work, including battery replacements in emergency lighting fixtures, must be performed by or under the supervision of a licensed electrical contractor. Beyond the legal requirement, improper battery selection or installation can create shock or fire hazards. A licensed electrician ensures the correct battery type is installed, connections are secure, and the unit is tested for proper operation afterward.
