ADA Door Requirements for Commercial Doors: What Contractors and Specifiers Need to Know

ADA door requirements for commercial buildings come from the 2010 ADA Standards for Accessible Design, Section 404. An ADA compliant commercial door provides at least 32 inches of clear width, the required maneuvering clearance on both sides, hardware operable with one hand and mounted 34 to 48 inches above the floor, no more than 5 pounds of opening force on interior hinged doors, and a threshold no higher than 1/2 inch.

Quick answer: To meet ADA door requirements, a commercial door needs 32 inches of clear width with the door open 90 degrees, maneuvering clearance on the push and pull sides, lever or other hardware that works without tight grasping at 34 to 48 inches, a 5 lbf maximum opening force on interior hinged doors, a closer that takes at least 5 seconds from 90 to 12 degrees, a smooth push side at least 10 inches high, and a threshold of 1/2 inch or less. Mills & Nebraska preps doors, frames and hardware to these dimensions in house.

What are the ADA door requirements for commercial buildings?

The ADA door requirements for commercial buildings are the Section 404 rules for clear width, maneuvering clearance, thresholds, hardware, closing speed, opening force and door surfaces. They apply to doors on accessible routes in new construction and alterations of public accommodations and commercial facilities. The U.S. Access Board guide to Chapter 4 explains each rule with diagrams, and the full text is in the 2010 ADA Standards for Accessible Design.

Florida projects also follow the accessibility volume of the Florida Building Code, so check the edition your jurisdiction enforces. Our Florida Building Code guide covers how state code fits with rated openings.

What is the ADA door width for commercial doors?

The minimum ADA door width is 32 inches of clear opening, measured from the face of the door to the stop with the door open 90 degrees. That is not the door leaf size: a 36 inch door is the common choice because a 34 inch leaf often nets less than 32 inches clear once the stop and hinge are accounted for.

• Openings deeper than 24 inches need 36 inches of clear width.
• Nothing may project into the clear width below 34 inches above the floor, and projections between 34 and 80 inches are limited to 4 inches.
• In a pair of doors, at least one active leaf must provide the 32 inch clear width on its own.

How much maneuvering clearance does an ADA door need?

Maneuvering clearance is the level floor space a wheelchair user needs to approach, open and pass through a door, and it depends on the approach direction and the side of the door. The most common case is a front approach, where the pull side needs 60 inches of depth and at least 18 inches beyond the latch side, and the push side needs 48 inches of depth.

• Front approach, push side: add 12 inches beyond the latch side when the door has both a closer and a latch.
• Hinge side approach, pull side: 36 inches beyond the latch with 60 inches of depth, or 42 inches beyond the latch with 54 inches of depth.
• Recessed doors: if anything within 18 inches of the latch side projects more than 8 inches from the door face, front approach clearances apply.
• Doors in series: the space between two hinged doors must be at least 48 inches plus the width of any door swinging into that space.

Clearance problems are layout issues, so catch them at the door schedule stage, before frames are ordered. Mills & Nebraska's hardware specification service reviews openings with an Architectural Hardware Consultant on staff.

What door hardware is ADA compliant?

ADA compliant door hardware can be operated with one hand without tight grasping, pinching or twisting of the wrist, and it is mounted 34 to 48 inches above the floor. Lever handles, U-shaped pulls and push bars meet that test; round knobs do not.

• Locks and latches with small thumb turns that need pinching do not comply, but separate keys and access cards are not required to comply.
• Operable parts must work with 5 lbf maximum.
• Exit devices, levers and closers should be selected as a coordinated hardware set so the latch, closer and opening force work together.

What is the maximum ADA door opening force?

The maximum opening force for interior hinged doors is 5 pounds (5 lbf), and the same limit applies to sliding and folding doors. Exterior hinged doors have no ADA maximum, because closers must overcome wind and stack pressure to latch, and fire doors are allowed the minimum opening force the authority having jurisdiction permits.

The Access Board recommends measuring with a pressure gauge placed about 2 1/2 inches from the latch edge, near the hardware centerline, pushing slowly and keeping the gauge perpendicular to the door face.

How fast can an ADA door close?

A door closer must be adjusted so the door takes at least 5 seconds to move from 90 degrees open to 12 degrees from the latch. Spring hinges must take at least 1.5 seconds to close from 70 degrees to 0 degrees. Closer speed drifts after installation, so check it again at turnover.

What threshold height does ADA allow?

Thresholds must be no higher than 1/2 inch, and any change in level over 1/4 inch must be beveled no steeper than 1:2. Existing or altered thresholds up to 3/4 inch high are allowed when they have a beveled edge on each side at that slope.

Does a door surface or vision lite matter for ADA?

Yes. The push side of a swinging door must be smooth from the floor to at least 10 inches high, with joints no more than 1/16 inch out of plane, because wheelchair footrests are used to push doors open. A full-height kick plate with capped edges satisfies this. Where a door has a vision lite, the bottom of at least one glazed panel must be no more than 43 inches above the floor.

Does the ADA require automatic doors?

No. The ADA does not require automatic or power-assisted doors, but when they are provided they must comply with Section 404.3 and the referenced ANSI/BHMA standards. Many owners add a low-energy operator at the main entrance, where the exterior door carries no opening force limit, to make the door easier for everyone. Doors can be prepped for operators and sensors during fabrication.

Which commercial doors can meet ADA requirements?

Any commercial door type can meet ADA requirements when the leaf size, hardware prep, closer and threshold are specified correctly. Hollow metal doors and steel frames suit high-traffic corridors and stairwells, and wood doors suit offices, hotels and healthcare interiors.

Mills & Nebraska fabricates hollow metal frames and preps doors in its 36,000 sq ft Orlando facility and holds Intertek certification for in-house fire and wind labeling, so doors that must be both accessible and fire-rated can be prepped and labeled without sending them out. For field work, our installation team sets frames, hangs doors and adjusts closers across our Florida service areas.

Common ADA door mistakes on commercial projects

• Hardware mounted outside 34 to 48 inches, often on retrofitted doors or at secondary locks.
• A 34 inch leaf specified where the opening needs a true 32 inches clear.
• Closers left at factory settings that close faster than 5 seconds or exceed 5 lbf on interior doors.
• Thresholds over 1/2 inch without a compliant bevel.
• Walls, casework or equipment placed inside the latch-side clearance after the door schedule was approved.

FAQs

What makes a commercial door ADA compliant?

A commercial door is ADA compliant when it meets Section 404 of the 2010 ADA Standards: 32 inches of clear width, the required maneuvering clearances, hardware operable with one hand at 34 to 48 inches, 5 lbf maximum force on interior hinged doors, a closer of at least 5 seconds from 90 to 12 degrees, and a threshold of 1/2 inch or less.

Can fire-rated doors also meet ADA requirements?

Yes. Fire-rated hollow metal and wood doors can meet ADA requirements when the leaf size, hardware and threshold are specified for both. The ADA lets fire doors use the minimum opening force the authority having jurisdiction allows, since a closer must still latch the door. Plan hardware prep before the door is labeled, because field changes to a labeled door are restricted.

Do ADA door requirements apply to bathroom doors?

Yes. Toilet room doors on an accessible route must meet the same Section 404 rules for clear width, clearance, hardware and force. The 2010 Standards also do not let the door swing into the clear floor space required at any fixture. In a single-user toilet room, the door may swing over that space only if a 30 by 48 inch clear floor space is provided beyond the door swing.

Is a 36 inch door required for ADA?

No. The ADA sets a 32 inch minimum clear width, not a door size. A 36 inch door is the usual specification because it reliably nets more than 32 inches clear with standard hinges and stops, while a 34 inch door can fall short. Doorways deeper than 24 inches need 36 inches of clear width.
