- Egress door = minimum 32″ clear width, 78″ height, swings outward for Fast escape.
- Opening force ≤5 lbs; unlatching force ≤15 lbs- no keys or special knowledge needed.
- Double-cylinder deadbolts prohibited; use panic hardware for one-motion exit.
- Fire doors self-close + block flames; egress doors focus on escape path (some do both).
- Inspect annually: measure width, force, swing, threshold; keep area unobstructed.
When something goes wrong inside a building, egress doors are how people get out. These doors let occupants leave a room, a floor, or a building in an emergency. This blog covers the basics: what an egress door is, how it differs from an exit door and a fire door, and the code requirements all of these doors must meet.

What Does Egress Door Mean?
By definition, egress means a way out. So an egress door is a door designed to provide a route out of a building. These doors give occupants a clear path outside, and must keep them open at all times.
Egress doors help people escape. Every dwelling unit must have at least one main egress door, and such doors have to comply with specific requirements so that anyone can leave quickly. Bedrooms additionally need an egress window that opens to a yard or open space, giving persons inside a second way out at ground level.
Egress vs. Exit: What Is the Difference?
People treat exit and egress as the same, but the code separates them.
Egress has three parts: the exit access that leads toward the exit itself, and the discharge that reaches a public way outside. The means of egress is the complete path from any point inside the building to the outside.
An exit is one part of that path. The exit door sits there, while egress doors can be any doors along the means of egress. Every exit door is an egress door, but not the reverse. In short, egress means the whole path, and the exit is the final door. That is the core difference between exit and egress.
Egress Doors vs. Fire Doors
Egress doors and fire doors are not the same, though one door can do both jobs. Egress doors help people escape. Fire doors slow the spread of flames and smoke so people have time to get out.
Not all egress doors meet fire door criteria. Fire doors are often installed in store rooms and private offices, where they stop fire from spreading between spaces. Such doors hold fire back, while egress doors focus on the path out. When a single door serves both purposes, it must comply with the rules for each. Additionally, fire doors must self-close, which not all doors do.
Egress Door Requirements
This section is where the code gets specific. Egress doors must provide a continuous path of travel to the outside, and that path must stay unobstructed.
Here are the core requirements these doors have to meet:
- Clear width: Egress doors must have the required minimum clear width of 32 inches. The clear width is measured across the door opening, from the face of the door to the stop, with the door fully open and its face clear. A door that extends or projects more than 7 inches into the required width fails.
- Height: The minimum required height for egress doors is 78 inches, measured from the floor to the door opening. These height requirements give occupants room to move, and the required height is rarely waived.
- Swing: Most side-hinged egress doors must swing in the direction of travel, depending on the occupant load. The occupant load of the room sets the rule. Side-hinged doors should swing outward, since outward-swinging doors clear faster.
- Opening force: Egress doors must open with no more than 5 lbs of force. The force to unlatch the door cannot exceed 15 lbf, which minimizes the effort needed to operate the door.
- Threshold: When measured, the exterior landing must sit no more than 1.5 inches lower than the threshold, so no one trips on the way out.
- No special knowledge: Egress doors must be operable without special knowledge, tools, or a key.
Side-hinged swinging doors are the most common door type, but the door opening, hardware, and swing of all door types must comply with code. Secondary doors may have different specifications, yet they must still allow a fast way out. For the exact width and height required by code, always comply with and reference your local code.
Can Egress Doors Be Locked?
Yes, but only in ways that never trap people inside. Egress doors must never be locked beyond the occupants’ control. Anyone inside must be able to open the door and leave without a key, without special knowledge, and without extra effort.
Double-cylinder deadbolts are prohibited on egress doors because they need a key to open from the inside. Doors equipped with approved panic hardware let occupants push and go, so the door opens with one motion. You can keep security tight without locking people in. The rule is simple: in the event of an emergency, no one should stop to hunt for a key.
Egress Door Maintenance
Rules only matter if the door still works. Egress doors should be inspected at least once a year to make sure they open easily, swing freely, and latch correctly.
During the inspection, measure the clear width, the door width, the opening force, and the threshold, then check the hardware on these doors against this section of code. Note any doors that fail to open with light effort, and fix them so these doors stay ready to ensure a safe way out. A blocked or broken door is a safety hazard and a risk on the day occupants need it most. Keep the area in front of these doors clear, post an exit sign above the area, and contact a licensed inspector if unsure.
