ADA Clearances at Doors: Width, Maneuvering, and Hardware

Under the 2010 ADA Standards for Accessible Design, ADA door clearance requirements set a minimum clear opening of 32 inches at every accessible doorway, measured between the face of the door and the opposite stop with the door open 90 degrees.¹ That single number is the piece most people remember, but it is only one of several requirements that have to line up together. A doorway can hit 32 inches and still fail because of the floor space in front of it, the threshold under it, the handle on it, or the closer above it. The rules apply to public accommodations and commercial facilities under Title III of the ADA, and to state and local government buildings under Title II.

Minimum Clear Opening Width

The 32-inch minimum applies to accessible doorways whether they sit inside or outside the building. Measure with the door open to exactly 90 degrees, from the face of the door to the stop on the opposite side of the frame. Nothing may project into that clear width below 34 inches above the floor. Between 34 and 80 inches above the floor, projections into the opening are capped at 4 inches.¹

Deep doorways get a bigger number. If the opening is more than 24 inches deep, as it often is in thick walls, vestibules, or recessed entries, the clear width must be at least 36 inches. In alterations to existing buildings, the latch-side stop may project up to 5/8 inch into the required clear width, a small concession that recognizes the difficulty of reworking older frames.¹

Maneuvering Space on Each Side of the Door

A wheelchair user needs room to approach the door, reach the hardware, and get out of the way of the swing. The floor space required depends on which side of the door the person is coming from and whether they are pushing or pulling.²

For a front approach on the pull side, the clearance is at least 60 inches deep, measured perpendicular to the doorway, and it must extend at least 18 inches past the latch side. That latch-side extension is what lets someone pull the door open without backing into a wall.

For a front approach on the push side, the depth drops to 48 inches. If the door has both a closer and a latch, you also need 12 inches of clearance past the latch side. The 12 inches is width beyond the latch, not additional depth; the depth stays at 48 inches.³

Hinge-side and latch-side approaches carry their own dimensions, which shift depending on whether the door has a closer.² These numbers get mixed up in the field, so keep the standard’s maneuvering-clearance table on hand during design and inspection rather than working from memory.

Floor Surface Inside the Maneuvering Area

The floor within a maneuvering clearance has to be stable, firm, and slip-resistant. Changes in level inside that area are not allowed, with two narrow exceptions: a slope up to 1:48 (about a quarter-inch per foot, enough to cover drainage or minor construction tolerances) and thresholds that meet the threshold rules below.¹

Carpet is a common problem. Maximum pile height is 1/2 inch, measured to the backing or pad. The carpet must have a firm backing, with level or textured loop, level cut pile, or level cut/uncut pile. Exposed edges must be trimmed and fastened down. Thick or cushiony carpet creates wheel resistance that makes even a compliant door hard to operate.⁴

Threshold Height

In new construction, a door threshold cannot exceed 1/2 inch. Any portion above 1/4 inch must be beveled at a slope no steeper than 1:2, so a half-inch threshold has a bevel extending at least one inch horizontally. That grade lets casters and wheels roll over rather than catch.⁵

Existing and altered buildings get a little more room: thresholds up to 3/4 inch are permitted, provided each side has a beveled edge no steeper than 1:2.⁶

Changes in level up to 1/4 inch need no treatment. Between 1/4 and 1/2 inch, they must be beveled. Above 1/2 inch, they must be treated as a ramp with a slope no steeper than 1:12.⁴

Hardware, Opening Force, and Closing Speed

Handles, pulls, latches, and locks on accessible doors must be operable with one hand and cannot require tight grasping, pinching, or twisting of the wrist.⁷ That rules out traditional round doorknobs. Lever handles, push-pull bars, and loop handles all pass. The Access Board notes that hardware operable with a closed fist or a loose grip accommodates the widest range of users.⁸ A deadbolt that has to be pinched and rotated does not comply.

The maximum force to open an interior hinged door, applied continuously after the latch is retracted, is 5 pounds. Two categories fall outside that cap. Fire doors have to meet whatever minimum force the fire code requires. Exterior hinged doors have no maximum specified under the ADA standards at all.⁵

The 5-pound measurement covers the force to swing the door once the latch is released. The initial pull needed to break an air seal from pressure differences does not count, and the latch bolt has to be retracted before measuring. Closers drift out of adjustment as they age, so periodic testing with a force gauge is the only reliable check.

Doors with closers also have a closing-speed requirement. The closer must be adjusted so the door takes at least 5 seconds to move from a 90-degree open position to 12 degrees from the latch. A door that slams shut in two or three seconds can strike a slower-moving user or trap a wheelchair’s footrests.

Vision Panels and Doors in Series

When a door, gate, or adjacent sidelight includes a glazed panel meant to see through, the bottom of at least one panel must be no higher than 43 inches above the finished floor. That height lets someone seated in a wheelchair see and be seen by a person approaching from the other side. The rule does not apply when the lowest part of the glazing sits more than 66 inches above the floor, since at that height the window is not serving a viewing function.⁹

When two hinged or pivoted doors face each other and a person has to pass through both, as in a vestibule or airlock, the space between them must be at least 48 inches plus the width of any door that swings into that space. Without that separation, a wheelchair user gets caught between the two doors, unable to reach the second handle without the first one striking them.⁵

Automatic and Power-Assisted Doors

The ADA does not require doors to be automated. When they are, the standards still apply. Power-assisted doors, which reduce but do not eliminate manual force, must meet the same maneuvering clearance, clear width, and threshold rules as any other door, and they must comply with the ANSI/BHMA A156.19 industry standard governing opening speed, safety features, and activation devices.⁵

Full-powered automatic doors, the kind that open on their own from a sensor or button, share the same 32-inch clear width and 1/2-inch threshold cap. Their activation controls have to be operable with one hand, without tight grasping or twisting, and require no more than 5 pounds of force. The clear floor space at the control must sit outside the door swing so the user does not get hit by the door opening.

New Construction, Alterations, and Existing Buildings

How strictly these numbers apply depends on what kind of project you have. New construction must meet every standard without exception. Alterations must comply too, though the rules include limited allowances like the 5/8-inch latch-side stop projection and the 3/4-inch existing-frame threshold.¹

Existing buildings that are not being altered fall under a different obligation. Barriers must be removed where doing so is “readily achievable,” meaning it can be accomplished without much difficulty or expense. The DOJ’s regulations list door-related examples: widening doorways, installing offset hinges to gain clear width, replacing inaccessible hardware, and removing turnstiles.¹⁰ When full compliance is not readily achievable, a partial modification is allowed so long as it does not create a health or safety risk.¹¹

Who Is Exempt

Two categories of organizations sit entirely outside Title III’s door clearance requirements. Religious entities are exempt, including places of worship and facilities they control such as schools, daycare centers, and thrift shops operated by a religious organization. Private clubs exempt under the Civil Rights Act of 1964 are also exempt.¹²

Historic buildings are not exempt. When strict compliance would threaten or destroy a historically significant feature, alternative requirements apply: the building must still provide at least one accessible entrance, an accessible route on the level of that entrance, and accessible restrooms where restrooms exist.¹³

What Noncompliance Costs

The Department of Justice can investigate complaints and file suit to enforce Title III. Courts may order compensatory damages and back pay in DOJ actions.¹⁴ Private individuals can file their own lawsuits seeking injunctive relief to force a fix.

In DOJ enforcement, civil penalties adjust annually for inflation. As of July 2025, the maximum is $118,225 for a first violation and $236,451 for each subsequent violation.¹⁵ Those are ceilings, not automatic fines; actual penalties turn on the severity of the violation, the entity’s good-faith efforts, and its financial resources. The numbers are high enough that correcting a noncompliant doorway is almost always cheaper than defending the enforcement action.
