IBC 2024 Egress Door Requirements: Width, Swing, Force, and Hardware

Under IBC 2024 Section 1010.1.1, an egress door opening must have enough capacity for the occupant load served and generally provide at least 32 inches (813 mm) of clear opening width and 80 inches (2032 mm) of clear opening height. For a swinging door, measure clear width between the face of the door and the frame stop with the door open 90 degrees.

Those dimensions are only the starting point. A complete check also covers door capacity, multiple leaves, projections, door type, swing direction, opening and unlatching forces, landings, thresholds, hardware, locks, panic hardware, fire-door requirements, and accessibility provisions.

This table is an orientation, not a replacement for the complete sections and exceptions.

Clear opening width is not nominal door-leaf width

Section 1010.1.1 regulates the clear opening that remains with the swinging door open 90 degrees. Do not record only a nominal leaf size or rough opening and assume the clear-width requirement is satisfied. Hinges, stops, hardware, the door face, and the frame configuration affect the measured opening.

Where a doorway has two leaves and no mullion, one leaf must provide the required 32-inch clear opening where Section 1010.1.1 requires that minimum. The total clear width of two partially opened leaves is not a substitute for that single-leaf requirement.

The section contains important exceptions. Examples include selected openings within dwelling and sleeping units, small storage closets, certain Group I-3 resident sleeping-unit doors, Type B unit doors, and nonaccessible sauna, toilet, dressing, fitting, or changing-compartment doors. Use the exception only when its complete scope applies.

Door capacity and minimum clear width are separate checks

Section 1005.3.2 generally uses a base capacity factor of 0.2 inch per occupant for components other than stairways. The conditional 0.15-inch factor is available only where the Section 1005.3.2 conditions are met, including the specified automatic sprinkler system and emergency voice/alarm communication system, and it is not available for Groups H and I-2.

Calculate the occupants served by the door, apply the appropriate capacity rule, and compare that result with the Section 1010.1.1 clear-opening provisions. The greater requirement governs. See the occupant-load guide, required-exits guide, and egress-capacity guide for the preceding steps.

Projections into the clear opening

Section 1010.1.1.1 does not permit projections into the required clear opening below 34 inches above the floor or ground. Between 34 and 80 inches, projections cannot exceed 4 inches.

An exception allows door closers, overhead stops, frame stops, power operators, and electromagnetic door locks to project into the opening height where they are not lower than 78 inches above the floor. This is a projection allowance, not a general reduction of the required door height.

Which way must an egress door swing?

Section 1010.1.2 establishes the permitted egress door types and lists specific exceptions. Section 1010.1.2.1 requires side-hinged swinging, pivoted, and balanced doors to swing in the direction of egress travel where they serve:

• a room or area with an occupant load of 50 or more; or
• a Group H occupancy.

The trigger is the occupant load of the room or area served, not merely the total population of the building. Calculate and document the load served by the door before applying the swing rule.

Opening force is not one universal 30-lbf value

IBC 2024 Section 1010.1.3 separates force to unlatch a door from force to open it.

For unlatching:

• push- or pull-operated hardware cannot require more than 15 lbf (67 N); and
• rotational hardware cannot require more than 28 inch-pounds (315 N-cm).

For opening:

• manually operated interior swinging egress doors that are not required to be fire rated cannot require more than 5 lbf (22 N) to push or pull open; and
• other swinging, sliding, or folding doors, including doors required to be fire rated, cannot require more than 30 lbf (133 N) to set in motion and must move to the full-open position with no more than 15 lbf (67 N).

Section 1010.1.3.1 applies these forces at the latch side. Fire doors, power-operated doors, special-purpose doors, and doors affected by pressure differences can also require review of their listing, referenced standard, or specific IBC provisions.

The previous shorthand “IBC allows 30 lbf for egress doors” is therefore misleading. The applicable value depends on the door and the force being measured.

Landings, floor elevation, and thresholds

Section 1010.1.4 generally requires a floor or landing on each side of a door at the same elevation, with listed exceptions for particular doors and conditions.

Section 1010.1.5 addresses landing dimensions. A landing must be at least as wide as the stairway or door, whichever is greater. A fully open door cannot reduce a required dimension by more than 7 inches. Where the landing serves 50 or more occupants, a door in any position cannot reduce the landing below one-half its required width. The general landing length in the direction of travel is 44 inches, with a 36-inch exception for the stated R-2, R-3, and U conditions.

Section 1010.1.6—not Section 1010.1.5—governs thresholds. It permits a threshold up to:

• 3/4 inch above the finished floor or landing for a sliding door serving a dwelling unit; or
• 1/2 inch for other doors.

Raised thresholds and changes in level greater than 1/4 inch must be beveled with a slope no steeper than 1 vertical to 2 horizontal. Accessibility provisions can impose their own threshold and maneuvering-surface requirements.

Egress-side operation and hardware

Section 1010.2 generally requires egress doors to be readily openable from the egress side without a key or special knowledge or effort unless a specific exception applies.

Key checks include:

• Section 1010.2.1 generally limits unlatching to one motion in a single linear or rotational direction and prohibits manual bolts, subject to its exceptions.
• Section 1010.2.2 requires hardware on doors required to be accessible by Chapter 11 to operate without tight grasping, tight pinching, or twisting of the wrist.
• Section 1010.2.3 generally locates operating hardware 34 to 48 inches above the finished floor, with listed exceptions.
• Section 1010.2.4 permits particular locks and latches only under its detailed conditions.
• Sections 1010.2.9 through 1010.2.15 contain distinct requirements for monitored, access-controlled, electrically locked, delayed-egress, controlled-egress, and related locking systems.

Do not summarize every access-control system as “fail safe.” Each permitted arrangement has its own occupancy limits, release sequence, power-loss behavior, fire-alarm or sprinkler interface, signage, listing, and emergency-lighting conditions.

When is panic or fire exit hardware required?

Section 1010.2.8 requires panic hardware or fire exit hardware on swinging doors serving:

• a Group H occupancy; or
• rooms or spaces with an occupant load of 50 or more in Group A or E.

The section has exceptions and installation requirements. Section 1010.2.8.2 also covers specified electrical-equipment rooms, transformer vaults, battery or energy-storage rooms, and modular data centers. Refrigeration machinery rooms larger than 1,000 square feet have a separate Section 1010.2.8.1 requirement.

Where the door is required to have a fire-protection rating, use listed fire exit hardware rather than treating ordinary panic hardware as interchangeable. Coordinate the assembly with Chapter 7, the door listing, and NFPA 80 where applicable.

ADA accessibility is a separate applicability check

The 2010 ADA Standards can apply independently of the model building code. Do not describe ADA as simply replacing the IBC or say one “wins.” Determine which legal and code requirements apply to the project and satisfy each applicable provision.

For manual doors on an accessible route, selected ADA Section 404 requirements include:

• Clear width: 32 inches minimum, measured between the door face and stop with a swinging door open 90 degrees. Openings more than 24 inches deep require 36 inches minimum under Section 404.2.3.
• Maneuvering clearance: Table 404.2.4.1 varies by approach direction, pull or push side, and the presence of a closer and latch. For a front approach, the pull-side example is 60 inches perpendicular plus 18 inches beyond the latch side; the push-side example is 48 inches perpendicular, with an additional 12 inches beyond the latch side where both a closer and latch are provided.
• Threshold: 1/2 inch maximum under Section 404.2.5. A listed exception permits certain existing or altered 3/4-inch thresholds with bevels.
• Hardware: operable parts generally 34 to 48 inches above the floor and operable with one hand without tight grasping, pinching, or twisting under Sections 404.2.7 and 309.4.
• Closing speed: a closer must take at least 5 seconds to move from 90 degrees to 12 degrees from the latch; spring hinges have a separate 1.5-second minimum under Section 404.2.8.
• Opening force: non-fire interior hinged doors and sliding or folding doors are limited to 5 lbf under Section 404.2.9. Fire doors use the minimum force allowed by the appropriate administrative authority.

Use the ADA resource hub and accessible-route width checker for the accessibility branch, while keeping IBC egress and federal accessibility analyses visibly distinct.

Door swing into an egress path

Section 1005.7.1 permits a door leaf to project into required egress width by no more than one-half at any point in its swing and by no more than 7 inches when fully open. A fully open door leaving 37 inches within a 44-inch required path does not fail solely because of that permitted seven-inch projection.

That allowance does not waive the door’s clear opening, landing, accessibility maneuvering clearance, fire-door, corridor, or other applicable requirements. See the corridor guide for the separate corridor-width and dead-end checks.

Common mistakes

Measuring the nominal leaf instead of the clear opening

Measure the actual opening at 90 degrees as required by Section 1010.1.1 and account for the frame stop and door face.

Applying 30 lbf to every egress door

Use the specific unlatching and opening-force categories in Section 1010.1.3. A non-fire-rated, manually operated interior swinging egress door uses the 5-lbf opening limit.

Citing Section 1010.1.5 for thresholds

In the 2024 IBC, landings are in Section 1010.1.5 and thresholds are in Section 1010.1.6.

Using the 50-person swing trigger as the panic-hardware rule for every occupancy

Direction of swing and panic hardware are separate provisions. Section 1010.2.8 applies the 50-person panic-hardware trigger to Groups A and E, while Group H is covered regardless of that threshold and special rooms have additional rules.

Treating IBC and ADA as one standard

Record the building-code and accessibility requirements separately, then use a door and hardware specification that satisfies every applicable condition.
