Lever Hardware Required

Door hardware must be operable with one hand and without tight grasping, pinching, or twisting of the wrist. Round knobs do not meet ADA requirements on commercial doors. Lever handles are the standard solution. If your building has round knobs on any accessible route, they need to be replaced with lever handles or lever-on-knob adapters.

Operating Force

Interior doors must open with no more than 5 pounds of force. Exterior doors are exempt from the force requirement but the hardware itself must still be operable with minimal effort. The 5-pound limit applies to the door, not the lock, but a lock with a stiff cylinder or a misaligned latch can push the total operating force over the limit. We test operating force on every installation.

Mounting Height

Hardware must be mounted between 34 inches and 48 inches above the finished floor. Standard mounting height is 36 to 38 inches to center of the lock. This applies to lever handles, deadbolts, keypads, and card readers. If a lock is mounted outside this range, it does not meet ADA regardless of the hardware type.

Maneuvering Clearance

The area around the door must provide enough clear floor space for wheelchair access. The clearance requirements vary by door type (push side vs. pull side) and approach direction, but the lock hardware cannot reduce the clear width of the doorway below 32 inches. Oversized lock bodies, surface-mounted closers, and protruding card readers can all encroach on required clearance.

Automatic Door Openers

For doors that serve high-traffic accessible routes, automatic door openers may be required or recommended. We install electrified locks that integrate with automatic opening systems, including push-plate activators, motion sensors, and touchless wave-to-open sensors. The lock must release before or simultaneously with the opener activating to prevent the door motor from working against a locked door.

Panic Hardware Required on Egress Doors

Any door in an exit path serving an occupant load of 50 or more must have panic hardware (push bars or touch bars). This applies to the final exit door and every door between the occupied space and the public way. Standard locks with levers or knobs are not permitted on these doors, they must have a device that opens with a single push motion without a key, special knowledge, or effort.

Locks Cannot Be Defeated from Egress Side

You cannot install a lock on any egress door that requires a key, code, or special knowledge to exit from the inside. Double-cylinder deadbolts (keyed on both sides) are prohibited on commercial exit doors. If a door has a deadbolt, it must have a thumbturn or lever on the interior side that always allows free exit. The only exception is delayed egress systems that meet specific code requirements and are tied to the fire alarm.

Delayed Egress Locks

Delayed egress locks are permitted in specific occupancies (Groups A, B, E, F, I-1, I-2, I-4, M, R-1, R-2, S) where the building is fully sprinklered and has a fire alarm system. The lock must release within 15 or 30 seconds (depending on the installation), sound an alarm during the delay, and release immediately when the fire alarm activates. The lock must also release on loss of power. Every delayed egress installation requires coordination with the fire alarm panel.

Stairwell Re-Entry Requirements

In buildings four or more stories tall, stairwell doors must allow re-entry from the stairwell to every fourth floor as a minimum, with re-entry always available on the top floor and the floor of exit discharge. This means the lock function on stairwell doors must allow entry from the stair side on the designated re-entry floors while remaining locked from the stair side on other floors. The lock selection must account for these re-entry requirements.

Fire-Rated Door Hardware

Locks installed on fire-rated doors must carry a UL or WHI label that matches the fire rating of the door assembly. A lock that is not listed for fire-rated doors can void the fire rating of the entire assembly. This includes the lock body, the strike, the trim, and any electrified components. We verify fire ratings on every door before selecting hardware.
