It’s that time of year again—no, not the holidays. We’re talking about your annual fire inspection. That one visit from your local fire marshal can determine whether your business is up to code—or facing fines, citations, and unexpected expenses for emergency lights, exit signs, or other egress system upgrades.
If you’ve failed a past inspection—or are just nervous you might—review these 10 common mistakes that business owners, facility managers, and contractors often overlook. This is your chance to correct them before the inspector walks through the door. And remember: preparation is easier (and cheaper) than last-minute corrections.

1. Unmarked or Invisible Street Address
If first responders can’t find your building, seconds lost could cost lives. Your street address must be clearly visible from the road—even in poor lighting or weather conditions. Install wall pack lights near address signage to boost visibility and pass nighttime inspections. Use contrasting numerals (at least 4" tall with a clear stroke), place them where landscaping won’t block sightlines, and consider reflective or illuminated numerals for long approaches.
2. Exit Doors Difficult to Open from Inside
Emergency exits must open easily—without keys, codes, or special tools. Panic hardware and push bars should release doors with one quick motion. If any doors require extra effort, it’s time to upgrade before inspection day. Pro tip: do a weekly “push test” on all egress doors; lubricate sticky hardware, remove door wedges, and verify any magnetic locks release on fire-alarm signal and power loss.
3. Blocked Egress Paths
Stairwells, corridors, and exits must remain completely unobstructed. Blocked routes are one of the fastest ways to fail a fire inspection. Use signage or floor tape to keep paths clear—and educate your team on the importance of compliance. Maintain required corridor width (often 36–44"+ depending on occupancy), keep self-closing fire doors unobstructed, and remove seasonal displays that encroach into exit access.
4. Non-Functional Emergency Lights or Exit Signs
Exit signs and emergency lighting must illuminate for a full 90 minutes during a power failure. Batteries, lamps, and internal circuits should be tested monthly. Consider self-testing models to automate the process and ensure readiness. Keep a simple binder/log: record monthly 30-second tests and the annual 90-minute test, replace weak batteries proactively, and confirm exit sign arrows match actual egress direction.
5. Exposed Electrical Panels or Junction Boxes
All electrical panels must have protective covers, with at least 30 inches of clear access in front. No storage, no furniture, no excuses. Install metal faceplates on any open junction boxes to avoid citations and potential shock risks. Mark the floor with high-contrast tape as a “no-storage zone,” replace missing knockouts with filler plugs, and ensure panel directories are legible and up to date.
6. Permanent Use of Extension Cords
Extension cords are temporary by design. If you’ve got cords plugged in year-round, your inspector will notice. Instead, have outlets installed by a licensed electrician and avoid daisy-chaining power strips or overloading circuits. Route any short-term cords away from doorways and walk paths, never under rugs, and label them with a removal date so “temporary” doesn’t become permanent.
7. Fire Extinguishers Missing or Not Maintained
Each extinguisher must be visible, accessible, and have a current inspection tag (serviced in the last 12 months). Do in-house visual checks monthly and make sure your team knows how to use them (remember: PASS — Pull, Aim, Squeeze, Sweep). Mount them at the correct height (typically 3.5–5 ft handle height), keep signage above for visibility, and ensure the gauge is in the green.
8. Un-Serviced Fire Sprinkler System
Sprinkler systems must be inspected and tested at regular intervals (annual inspections; 5-year internal piping checks—per your AHJ). Keep documentation on hand. In some cases, insurers may deny coverage if your suppression system fails due to lack of maintenance. Don’t store items within 18" of sprinkler deflectors, never paint sprinkler heads, and keep a spare-head kit available where required.
9. Unmaintained Kitchen Fire Suppression Systems
Commercial kitchens are a hotspot for fire inspection failures. Your suppression system must be inspected every 6 months, along with regular hood and duct cleaning. Missed service tags are a red flag for any inspector. Verify correct nozzle caps and aiming after any equipment moves, test the manual pull, and ensure fuel/electric interlocks shut equipment down during system discharge.
10. Improper or Unpermitted Storage of Hazardous Materials
Flammable liquids, compressed gases, and combustible stock must be stored safely and clearly labeled. Never place hazardous items near exits or egress paths. In many cases, special permits or cabinets are required—check your local code. Use listed flammable storage cabinets, secure cylinders, separate incompatibles (oxidizers vs. flammables), and keep SDS sheets accessible.
Quick Win: Keep a laminated inspection checklist near your utility closet or fire panel to remind staff of monthly compliance tasks. Add a calendar reminder for emergency light tests, extinguisher visual checks, and door hardware push tests.
Stay Compliant—and Safer
Fire inspections aren’t just about avoiding fines. They’re about protecting your people and ensuring emergency systems function under pressure. Stay aligned with NFPA 101 and local fire codes. Schedule your monthly lighting and extinguisher checks, train your team, and keep records up to date.
