Understanding Fire Door Requirements
Fire doors are not regular doors with a label. They are engineered assemblies designed to contain fire and smoke for a rated period - typically 20, 45, 60, or 90 minutes. Every component matters: the door itself, the frame, the hardware, the glazing, and the seals.
NFPA 80 (Standard for Fire Doors and Other Opening Protectives) and the Florida Building Code require that all fire door assemblies in commercial buildings be inspected annually. This is not optional - it is a life-safety requirement.

What Fire Door Inspectors Check
- Door and Frame ConditionNo holes, breaks, or damage that would compromise fire resistance. Labels must be legible. Clearances between door and frame must meet specifications.
- Hardware FunctionSelf-closing devices must fully latch the door from any open position. Latching hardware must engage properly. Panic hardware must operate correctly.
- Gasketing and SealsSmoke seals and intumescent strips must be present and undamaged. These swell during fire to seal gaps between door and frame.
- ClearancesMaximum 1/8-inch clearance at the top and sides. Maximum 3/4-inch clearance at the bottom (unless the door has a listed bottom seal). Excessive gaps allow smoke passage.
Most Common Fire Door Violations
After inspecting hundreds of commercial buildings across the Treasure Coast, these are the violations we find most frequently.
Top Fire Door Violations
- Door closer not latching the door fully from all positions
- Missing or painted-over fire rating labels
- Unapproved hardware modifications (holes drilled, kick plates added without fire-rated versions)
- Gaps exceeding maximum clearance specifications
- Doors propped open without approved hold-open devices connected to fire alarm
- Missing or damaged smoke seals and intumescent strips
Fire Door Compliance Tips
- Schedule annual inspections proactively - do not wait for the fire marshal visit
- Never prop fire doors open with doorstops, wedges, or furniture
- If you need doors held open, install magnetic hold-open devices connected to your fire alarm system
- Keep inspection reports on file for at least 3 years for fire marshal review
- Address violations immediately - most are repairable without full door replacement

Fire Door Repair vs. Replacement
Many fire door violations can be corrected through repair rather than costly replacement. A failing door closer can be replaced for $150 to $400. Missing seals can be installed for $50 to $150 per lock. Clearance issues can sometimes be addressed through frame adjustments.
However, if the door itself is damaged, warped, or has had unauthorized modifications that compromised its fire rating, replacement may be necessary. A qualified fire door inspector can determine whether repair or replacement is appropriate.
