Fire-rated walls and doors keep fire and smoke contained long enough for residents to get out and for firefighters to get in. But the system is only as strong as its weakest door. One propped-open stairwell door or one missing closer can defeat it.
In Washington, DC, owners, condo boards and property managers are responsible for keeping these doors working, and the fire marshal can cite a building when they don't. Here's a plain-language guide to the rules, and answers to the questions we hear most often.
Which rules apply in DC
Three sets of rules work together:
• The building code sets the required fire ratings when a building is built or renovated. DC currently enforces the 2017 DC Construction Codes, based on the 2015 International Building Code (in effect since May 29, 2020). The DC Department of Buildings (DOB) is working on an update based on the 2024 international codes, with final rules expected in late 2027.
• The DC Fire Code (Title 12-H of the DC Municipal Regulations) governs how existing buildings are maintained. For fire doors, it points to NFPA 80.
• NFPA 80, the national Standard for Fire Doors and Other Opening Protectives, sets how fire doors are installed, inspected, maintained and repaired.
Typical required ratings
The rating a door needs depends on the wall it sits in. Under the international building code tables DC uses, typical ratings are:
• Exit stairs, elevator and trash chute shafts in buildings of 4 or more stories: 2-hour walls, 90-minute doors
• Exit stairs and shafts in buildings under 4 stories: 1-hour walls, 60-minute doors
• Other 1-hour fire barriers such as trash, storage, mechanical and electrical rooms: 45-minute doors
• Corridor walls and unit entry doors in sprinklered apartment and condo buildings: 20-minute doors with smoke seals
• Fire walls between buildings: 3-hour walls, 3-hour doors
In every case, the door must close on its own and latch. These ratings are typical, not universal. Your building's approved drawings and the label on each door and frame are what count.
What makes a fire door compliant
• Labeled door and frame. Both carry a permanent rating label, usually on the hinge edge. Never remove or paint over a label.
• Self-closing and latching. The door must close fully and latch on its own from any open position. No wedges, kick-down stops or tied-back doors. Hold-open devices are allowed only if they release when the fire alarm sounds.
• Gaps within limits. About 1/8 inch at the top and sides, and no more than 3/4 inch under the door.
• Listed hardware and glass only. Hinges, closers, locks, viewers and vision glass must be rated for fire doors.
• No field modifications. No unapproved holes, added deadbolts, pet doors, mail slots or cut-downs. Old holes are filled with steel fasteners, not caulk or tape.
• Like-for-like replacement. A replacement door must carry the same or a higher rating, with a matching rated frame and hardware.
Annual inspections under NFPA 80
NFPA 80 requires fire door assemblies to be inspected after installation, after any repair, and at least once a year by a qualified person. The inspection covers 13 points, including labels, holes, glass, hardware, gaps, closers, latching, gaskets, signage and field modifications.
Written records for each door must be kept and shown to the fire marshal on request, and problems must be fixed without delay.
The most common violations we find
• Doors propped or wedged open
• Closers missing, leaking or disconnected
• Latches that don't catch
• Gaps over the limit
• Labels painted over or missing
• Added deadbolts or peepholes that aren't rated
• Non-rated replacement doors
• Holes from old hardware left open
• Damaged smoke seals on unit entry doors
Your questions, answered
Do I need a DOB permit to replace fire-rated doors in DC?
In most cases, plan on it. DOB lists door replacement as work that needs a permit, and fire-rated doors are part of the building's fire protection and exit system, so replacing them is not treated as a simple cosmetic repair. Many smaller replacement projects can be permitted quickly online. Routine repairs that don't change the door, such as adjusting or replacing a closer or latch with rated parts, generally don't need a permit. Buildings in historic districts may also need historic preservation approval before the permit. When in doubt, check with DOB before work starts. A good contractor will handle the permit for you.
Do I have to replace the whole frame, or just the door?
Often just the door. If the existing frame is labeled, in good condition, securely anchored and rated for the same opening, you can usually replace only the door leaf with a new labeled door of the same or higher rating, plus listed hardware. The frame needs replacing if it's damaged, rusted out, bent, too worn to hold the hardware, or has no label that can be verified. Keep in mind that a door and frame must work as a rated pair: a 90-minute door in a 60-minute frame is still only a 60-minute opening.
What if my doors don't have the labels (stickers)?
Under NFPA 80, a fire door or frame without a legible label is treated as non-rated, even if it was originally a fire door. You have three options:
1. Field relabeling. An accredited testing and listing agency inspects the door on site and, if it matches the original listing and hasn't been modified, issues a new label. This takes time and costs money, but it can save a good door.
2. Approval of existing frames. For existing steel frames without a label, the fire code official can approve them case by case.
3. Replacement with a new labeled door, frame or both.
Never make or attach your own labels. Only an accredited agency can relabel a fire door.
Does the DC fire inspector come to inspect our doors?
Don't count on it, and don't wait for it. The DC Fire Marshal's office enforces the fire code and can inspect and cite a building, often after a complaint, an incident or as a follow-up. DC Fire and EMS also offers fire prevention inspections by appointment. But under NFPA 80, the annual fire door inspection is the owner's responsibility, and it's done by a qualified person you hire, not by the fire department. What the inspector will ask for is your written inspection records. Your insurance carrier may also ask for them.
