Where the requirement comes from
Florida’s fire code, the Florida Fire Prevention Code, is based on NFPA 101, the Life Safety Code. For apartment-type buildings, it treats a unit door that opens onto a corridor as part of the corridor’s protection. In practice that usually means three things: the door assembly has a fire protection rating, commonly 20 minutes; the door closes by itself; and it latches when it closes.
Miami-Dade Fire Rescue’s life safety review checklist for apartment buildings lists these same items for corridor doors. Older buildings can be held to different rules depending on when they were built and how they have been reviewed, so the final word belongs to the local fire official and your association.
A rating belongs to the whole assembly
A fire-rated door is tested as a system. The leaf, the frame, the hinges, the latch or lock, the closer and any glass all have to be suitable together. A fire-rated leaf hung in an unrated frame, or fitted with hardware that is not listed for fire doors, may not keep its rating.
| Part | What to check |
|---|---|
| Door leaf | A fire label, usually on the hinge edge, that shows the rating |
| Frame | Its own label, and a rating that matches the door |
| Hinges | Steel hinges of the type and number the listing requires |
| Closer | A closer that brings the door fully shut and latched |
| Lock or latch | Hardware listed for use on fire doors; it must latch positively |
| Glass or viewer | Only glazing or a viewer that is part of the listing |
| Gaps | Clearances at the edges and bottom within the listed limits |
Changes that can void the rating
Owners often damage a rated assembly without realizing it. Check with the manufacturer’s listing before any of these.
- Cutting the door for a new lock, a smart lock, a mail slot or a larger viewer
- Removing the closer or propping the door open
- Replacing hinges or the lock with decorative hardware that is not listed for fire doors
- Trimming the bottom of the door for a thicker floor finish
- Painting or covering the labels on the door and frame
- Adding glass, louvers or decorative cut-outs
Choosing a new entry door
Start with the building, not the design. Ask management for the required rating, any hardware standard and the corridor-side finish. Many buildings want every door to look the same from the corridor while letting owners choose the inside finish.
Then choose a door system that carries the required rating as a complete assembly. Interior design options such as flush faces, veneers and modern hardware are often available in rated versions, but they have to be confirmed for the specific product.
Smart locks and modern hardware
Electronic locks are a common request. On a rated entry door, the lock has to be listed for fire doors and must not require cutting the door beyond what its listing allows. Bring the lock model to the quote and we will check it against the door system.
A FEW USEFUL ANSWERS
Before you begin.
Is every condo entry door in Florida required to be fire-rated?
Not automatically. It depends on the building type, its age and the code it falls under. Most high-rise condo associations in South Florida expect a rated, self-closing unit entry door, so ask management for the requirement in writing.
Can I paint my fire-rated door?
Usually yes, as long as you do not paint over the labels on the door and frame. Check the building’s finish rules for the corridor side.
Do interior doors inside the unit need a rating?
Normally not. The requirement applies to the door between the unit and the corridor, not to bedroom or bathroom doors.
