ADA Accessible Entrance Requirements: Doors, Signage, and Penalties

ADA accessible entrance requirements govern how a business’s public doorways must be built and maintained so that people using wheelchairs, walkers, or other mobility devices can enter on their own. Under Title III of the Americans with Disabilities Act, private businesses that serve the public must provide barrier-free entry in new construction, and existing businesses must remove entrance barriers where doing so is readily achievable.¹ The rules reach every part of the doorway: how wide it opens, how high the threshold sits, how much force it takes to pull the handle, and what happens in the floor space around it.

How Many Entrances Must Be Accessible

In new construction, at least 60 percent of all public entrances must comply with the ADA’s door and entryway standards.² That calculation covers every doorway the public uses to enter from outside, not just the front door. A building with a single public entrance has no math to do: that entrance must be fully accessible. The point of the rule is to prevent routing disabled visitors to a back door while everyone else uses the front.

Connected structures add their own requirements. If a parking garage feeds directly into the building, at least one entrance from each garage level must be accessible. Elevated walkways and pedestrian tunnels connecting buildings need at least one compliant entrance at each connection point.³ In shopping centers and multi-tenant office buildings, at least one accessible entrance must serve each individual tenant space.⁴

Clear Width of the Door

The opening must be wide enough for a wheelchair to pass through. Minimum clear width is 32 inches, measured between the face of the door and the door stop when the door is open at 90 degrees.² Nothing can protrude into that 32-inch clearance below 34 inches above the floor, roughly the height of a wheelchair armrest.³ For openings deeper than 24 inches, such as vestibule entries, the clear width increases to 36 inches.

Double doors are common at commercial entrances. At least one of the two leaves must independently provide the full 32-inch clear opening. A person should not have to operate both doors at once to get through.

Threshold and Floor at the Door

The transition at the bottom of the doorway must be nearly flat. Thresholds cannot exceed half an inch in height. If a threshold rises more than a quarter inch, the edges must be beveled at a slope of 1:2 or gentler so wheelchair casters roll over the bump without catching.²

The floor within the maneuvering space around the door must be level. A slope up to 1:48 is permitted, which works out to about a quarter-inch rise per foot and is essentially flat.² Surfaces on both sides of the entrance must be stable, firm, and slip-resistant. This is not only a safety issue. A sloped surface at a doorway pulls the door shut under gravity and can roll an unbraked wheelchair away from the handle.

Hardware and Opening Force

Handles, locks, and latches must be usable with one hand, without a tight grip, a pinching motion, or a twist of the wrist.² Lever handles, push bars, and U-shaped pulls satisfy that test. Round doorknobs do not. All door hardware must be mounted between 34 and 48 inches above the finished floor.⁵

Interior hinged doors and sliding doors must require no more than 5 pounds of force to open.⁶ The ADA does not set a specific pound-force limit for exterior hinged doors, because wind loading, weather sealing, and HVAC pressure all affect how hard they push open. The U.S. Access Board recommends automating exterior doors where opening force is likely to be significant, and otherwise calibrating closers with the minimum force needed for the door to latch.³ Difficulty opening manual entrance doors is one of the most common accessibility complaints.

Where a door uses a closer, the closer must be adjusted so the door takes at least 5 seconds to swing from a fully open position (90 degrees) down to 12 degrees from the latch. A faster closing speed can strike a slower-moving person or catch a wheelchair mid-passage.

Maneuvering Clearance and Vision Panels

The floor area around a door needs enough space for someone to position a wheelchair, reach the handle, and swing the door open without backing into a wall. Required clearance extends the full width of the doorway plus additional space on the latch side or hinge side, depending on the direction of approach and whether the door swings toward or away from the person.⁷ A pull-side approach generally demands deeper clearance than a push-side approach, since the person must back up as the door swings toward them. Because dimensions vary by configuration, the ADA Standards lay out each combination in a dedicated table, and getting this right usually means checking that table against your specific entrance layout.

Doors and sidelights with glass panels must position the bottom of at least one panel no higher than 43 inches above the floor.⁸ That lets a seated person see through the door before opening it, and lets people on both sides spot each other. Panels sitting entirely above 66 inches are exempt.

Keypads, Card Readers, and Intercoms

Electronic access controls at entrances count as operable parts and follow the same rules as door hardware. Mount them between 34 and 48 inches above the floor, make them operable with one hand, and keep the force required to activate them at or below 5 pounds.² A card reader installed at 54 inches because that is where the stud happened to be is a routine oversight that creates a real barrier for seated users.

Signage at Entrances

When not every entrance is accessible, the building must use signage to point people to one that is. Each accessible entrance displays the International Symbol of Accessibility. Each inaccessible entrance carries a directional sign pointing to the nearest accessible entrance, and those directional signs must meet the ADA’s visual requirements for character size, contrast, and finish.⁹ If every entrance in the building is accessible, no entrance signage is required.

The Accessible Route to the Door

An entrance only counts as accessible if a person can actually reach it. The ADA requires a continuous, unobstructed path connecting the entrance to site arrival points: accessible parking spaces, passenger loading zones, public sidewalks, and public transit stops.¹⁰ That path cannot include stairs, abrupt level changes, or detours that force a person off the route.

Where the route meets a change in elevation, a ramp is the usual answer. Maximum running slope is 1:12, one inch of rise per 12 inches of run. Steeper slopes are allowed only for short rises: up to 1:10 for a maximum 6-inch rise, or up to 1:8 for a maximum 3-inch rise. Cross slope cannot exceed 1:48.¹¹ Each ramp run is capped at 30 inches of total rise before a level landing is required, though a ramp can have as many runs as the site demands. Handrails are required on both sides of any ramp with a rise greater than 6 inches, running continuously with 12-inch extensions at the top and bottom.

Protruding Objects Along the Path

Wall-mounted items near the entrance can create hazards for people with vision impairments. Any object mounted with its leading edge between 27 and 80 inches above the floor can protrude no more than 4 inches horizontally into the circulation path.¹² Objects below 27 inches are detectable by a cane. Objects above 80 inches clear everyone’s head. The zone between them is the problem, because a cane sweeps at floor level and misses anything jutting out at waist height. Overhead clearance along the route must be at least 80 inches, and where it dips lower (under stairs, sloped ceilings, decorative archways) a barrier or guardrail no higher than 27 inches must sit underneath to redirect traffic.

Existing Buildings: Readily Achievable Barrier Removal

The dimensions above apply in full to new construction. Existing buildings face a different standard. Businesses operating in older facilities must remove architectural barriers, including entrance barriers, where doing so is “readily achievable” — done without much difficulty or expense.¹³ Whether a given fix qualifies depends on the size and financial resources of the business and the cost of the improvement. This is an ongoing evaluation, not a one-time judgment. As a business’s circumstances change, so does what is readily achievable.¹⁴

Common entrance changes that often qualify: installing a ramp over a single step, swapping a round doorknob for a lever handle, widening a doorway, and adjusting a door closer to lower the opening force. When full compliance is not readily achievable, businesses should still make whatever partial improvements they can, provided the change does not create a safety hazard.

Safe Harbor for Elements Meeting the 1991 Standards

An element-by-element safe harbor protects businesses that already brought their facilities into compliance with the original 1991 ADA Standards. If a specific element (a door’s clear width, a threshold’s height) met the 1991 Standards and has not been altered since March 15, 2012, the business is not required to update that element to meet the 2010 Standards.¹ The safe harbor disappears the moment the element is altered or replaced. After that, the 2010 Standards apply.

What Non-Compliance Costs

People with disabilities can file private lawsuits under Title III in federal court. A private suit can produce a court order requiring the business to fix the barrier, but private plaintiffs cannot recover money damages. Injunctive relief is the remedy, along with attorney’s fees and litigation costs at the court’s discretion.¹⁵

The U.S. Department of Justice can also enforce Title III, and those cases carry more financial weight. DOJ actions can produce money damages for people harmed by the violation, plus civil penalties of up to $118,225 for a first violation and up to $236,451 for subsequent violations.¹⁶ Punitive damages are not available in either type of case. Most ADA entrance cases settle before trial, but the combination of attorney’s fees exposure and DOJ penalty risk gives even a small claim leverage. Fixing a threshold or a doorknob is almost always cheaper than defending a lawsuit about one.
