Most commercial doors that fail an ADA inspection weren’t installed wrong. They were installed correctly and then drifted out of compliance over time, a closer adjusted too tight after a complaint about a door slamming, a new threshold added during a flood-proofing update, hardware replaced by whoever was available that week. None of it looks like a violation from a walk-through. All of it can fail a measurement.
An ADA door compliance audit checks four specific measurements against the 2010 ADA Standards for Accessible Design. Here’s what each one means and why doors fail.
The Four Measurements
1. Opening Force
Standard: 5 lbf maximum for interior hinged doors, 8.5 lbf maximum for exterior doors, per ADA Section 404.2.9 and ANSI A117.1.
Opening force is how much push or pull a person needs to apply to open the door. Measured with a pressure gauge (a force gauge, sometimes called a fish scale, hooked to the door’s leading edge). Doors fail this most often because of a closer spring tension that’s too high, a worn or misaligned frame creating drag, or weatherstripping compressed too tightly against the door.
2. Closing Speed
Standard: 5 seconds minimum for the door to travel from a 90-degree open position to 12 degrees from the latch, per ADA Section 404.2.8.1 ADA.gov, 2010 ADA Standards for Accessible Design.
This is the measurement people call “the ADA closing speed standard.” It’s not about how fast the door slams shut at the very end, it’s about how much time someone has to get through the doorway before the door swings most of the way closed. A door that snaps shut in two seconds doesn’t give someone using a wheelchair, a walker, or a cane enough time to clear the opening. Facilities using door closers with spring hinges instead have a separate standard: 1.5 seconds minimum from 70 degrees to fully closed, under Section 404.2.8.2 ADA.gov.
Closing speed is checked with a stopwatch, timing the door through that specific swing range.
3. Clear Width
Standard: 32 inches minimum clear opening, per ADA Section 404.2.3.
Clear width is measured from the face of the door (when open 90 degrees) to the opposite door stop, the actual usable passage width, not the width of the door slab itself or the frame’s rough opening. This is measured with a tape measure at the narrowest point of the passage.
4. Hardware Height
Standard: Operable hardware mounted between 34 and 48 inches above the finished floor, per ADA Section 404.2.7.
This covers door handles, push bars, panic hardware, and any other operable part someone needs to reach to get through the door. Anything mounted outside that 34 to 48 inch band fails, regardless of how well the rest of the door performs.
What Fails Most Often
In practice, four issues account for most ADA door failures on commercial properties:
- Closers adjusted too fast. Usually done to stop a door from staying open too long, letting in bugs, losing air conditioning, or annoying staff, with no consideration for the closing speed standard.
- Openings narrowed after installation. Added weatherstripping, a new threshold for water intrusion, or a repainted frame can each shave fractions of an inch off clear width. Enough small changes stack up to a failing measurement.
- Hardware mounted at the wrong height. Common when hardware is replaced piecemeal over the years by different vendors without a tape measure in hand.
- Opening force creeping up. A closer that was compliant when installed drifts out of spec as springs age, or as a frame settles and creates drag.
Who Enforces This
ADA door compliance comes up in three ways for a commercial property owner. First, the local building department checks it during permitted renovation inspections. Second, a complaint from an employee or a customer can trigger a review, this doesn’t require a lawsuit to start, just someone reporting the issue. Third, the U.S. Department of Justice can pursue enforcement actions directly under Title III of the ADA for places of public accommodation.
The Cost of Non-Compliance
South Florida sees a steady volume of ADA-related demand letters and lawsuits against commercial properties, often triggered by a single visit from someone who couldn’t get through a door, a bathroom, or a parking lot without difficulty. A door opening force problem measured with a $30 gauge can be the entire basis for a legal claim. Fixing the door after a demand letter arrives costs the same as fixing it before, but by then, legal fees are already on the table.
How an Audit Works
A proper ADA door audit checks all four measurements on every door subject to the standard, not a sample. The tools are simple: a pressure gauge for opening force, a stopwatch for closing speed, and a tape measure for clear width and hardware height. What matters is consistency, checking every door, on every visit, the same way, and documenting the readings so there’s a record of what passed and what didn’t.
Common areas that get missed in a self-check: back-of-house doors that employees use constantly (still subject to the standard if the space is otherwise accessible), single doors in a pair where only one leaf is normally used (both still need to meet clear width if both are intended for use), and doors that were compliant at installation but have drifted since.
Fixing What Fails
Most ADA door failures don’t require a new door or a new frame. The most common fixes are:
- Closer speed adjustment. Most commercial closers have separate valves for main sweep speed, latch speed, and backcheck. Correcting closing speed is usually a valve adjustment, not a parts replacement.
- Hardware relocation. Moving a lever, push bar, or panic device to the compliant 34 to 48 inch band.
- Threshold modification. Replacing or reshaping a threshold that’s created a trip hazard or narrowed the opening.
Doors That Get Overlooked
A self-check of ADA doors often focuses on the obvious ones, the main entrance, the front lobby door, maybe the accessible restroom. That leaves out a category of doors that are just as often cited on a formal inspection. Back-of-house doors used constantly by staff are still subject to the standard if the overall space is open to the public. In a paired door, two door leaves side by side where only one is normally unlocked for daily use, both leaves generally still need to meet clear width requirements if both are intended to be usable. And a door that was correctly adjusted at the time of a renovation five years ago may have drifted since, particularly on closer speed and opening force, neither of which stays fixed once weather, use, and minor repairs start acting on the hardware over time.
Interior Doors Count Too
ADA compliance isn’t limited to the doors a visitor sees walking in from the parking lot. Interior doors along an accessible route, a hallway door leading to a conference room, a restroom door, a door into a break room that’s part of the path an employee or visitor would reasonably need to use, are subject to the same four measurements. A building can have a fully compliant front entrance and still fail an audit because of a single interior door with hardware mounted six inches too high.
Documenting an Audit Properly
An audit that isn’t documented doesn’t hold up if a complaint is later filed. For each door checked, a usable record includes the door’s location, the four measurements taken, the date of the check, and any adjustment made as a result. This documentation does two things: it gives the building a clear maintenance record showing which doors have been checked and cleared, and it gives the property owner something concrete to show if a complaint is ever filed claiming a specific door was out of compliance. A dated record showing the door was checked and passed, or was checked, found out of compliance, and corrected, is a meaningfully different position than having no record at all.
A Recurring Issue, Not a One-Time Fix
ADA door compliance isn’t a box that gets checked once during a renovation and then forgotten. Closers drift out of adjustment as springs age and hydraulic fluid breaks down. Frames settle. Hardware gets swapped by different vendors over the years without anyone re-measuring against the standard. A property that passed an audit three years ago isn’t guaranteed to pass one today, particularly on the two measurements most prone to drift: opening force and closing speed. Building an ADA door check into a routine maintenance schedule, rather than waiting for a complaint or an inspection, is the only way to reliably stay ahead of it.

Beyond the Four Measurements: Other Door Items an Audit Should Cover
Opening force, closing speed, clear width and hardware height are the numbers most people associate with ADA doors, but Section 404 of the 2010 Standards covers more than that. A thorough audit of a Broward commercial building looks at the whole door opening, including the floor in front of it, the threshold under it and the shape of the hardware itself. The items below are where audits most often find problems that a quick check of the big four would miss.
Hardware Shape and Operation
The height of a handle is only half of the hardware requirement. The 2010 Standards also require that operable parts can be used with one hand and without tight grasping, pinching or twisting of the wrist. That is why round doorknobs do not meet the standard on doors along an accessible route, even if they sit at the right height. Lever handles, push and pull hardware, and panic bars generally satisfy this requirement.
The same rule applies to locks. A thumbturn that is small, stiff or requires pinching can create an issue on a restroom or office door. If a lock requires a key on the inside to get out, it creates a separate life safety problem as well. An audit should check every operable part a person has to use to pass through the door, not just the main handle.
Thresholds
Thresholds are a frequent problem in South Florida, where many buildings have added or raised thresholds to keep out wind-driven rain. Under the 2010 Standards, thresholds at most doors are limited to a height of 1/2 inch. Changes in level up to 1/4 inch can be vertical, and changes between 1/4 inch and 1/2 inch need a bevel no steeper than 1:2. A threshold that was replaced during a storm-hardening project with a taller or square-edged profile is worth measuring during the audit.
Maneuvering Clearance
A person using a wheelchair needs clear floor space on both sides of a door to approach it, reach the hardware and pull or push it open. The required clearance depends on the direction of approach and whether the person is pulling or pushing. On the pull side of a door approached from the front, for example, the Standards call for clear space extending beyond the latch side of the door. In practice, maneuvering clearance is often lost after move-in rather than during construction. A trash can, a coat rack, a display fixture or a stack of boxes parked beside a door can eliminate the clearance even though the architecture complies.
Maneuvering clearance is not something a locksmith can fix with a wrench, but documenting it during the audit gives the property manager a list of items that need to be moved or relocated so the door functions as designed.
Door Surface Near the Floor
Swinging doors on an accessible route generally need a smooth surface on the push side within 10 inches of the floor, so a wheelchair footrest can push the door without catching. Doors with a raised bottom rail, decorative molding, exposed hardware or a kick plate with sharp edges at that height may need a closer look. Adding a properly sized kick plate is a common solution on doors that already have a smooth bottom rail.
Doors in a Series
Vestibules and airlock entries are common in South Florida buildings because they keep conditioned air in the lobby. When two doors are placed one after another, the Standards require enough space between them for a person using a wheelchair to clear one door before opening the next. Vestibules that were reduced during a renovation, or that had furniture or signage stands placed inside them, can fail this requirement.
Vision Lites
Doors and sidelights with glass along an accessible route should have at least one panel of glazing with its bottom edge no higher than 43 inches above the floor, so people who are seated can see through. This applies when the door has glass, not to solid doors. It is rarely something that drifts over time, but it is worth recording during the audit so the report covers the whole opening.
Fire Doors and Opening Force
Fire-rated doors are treated differently when it comes to opening force. The 2010 Standards do not set a numerical maximum for fire doors; instead, they defer to the minimum opening force allowed by the local authority having jurisdiction. That is because a fire door needs a closer strong enough to shut and latch the door reliably against air pressure during a fire.
In practice, this means a stairwell or corridor door that is fire rated cannot simply be dialed down to the lightest possible setting. The goal is the lowest force that still closes and positively latches the door every time. That balance often takes a closer with adjustable spring power rather than a fixed-size unit, and it should be checked with the door fully latching from several open positions, not just from wide open.
Automatic and Power-Assisted Doors
Many retail entrances, medical offices and condo lobbies in Broward use automatic operators or low-energy power-assisted operators to solve opening force problems. These operators are covered by their own standards from the Builders Hardware Manufacturers Association rather than by the manual door force limits. A low-energy operator on a swinging door is typically activated by a push plate or wave sensor mounted within reach from the approach path.
During an audit, it is worth confirming that the actuator is located where a person using a wheelchair can reach it without being in the door’s swing path, that the door stays open long enough to pass through, and that the door still functions manually when the power is off. A power outage or a failed operator should not leave a door that is impossible to open by hand.
Restrooms and Single-User Rooms
Restroom doors are among the most frequently cited in ADA reviews because every element is in a small space. Common restroom door problems include:
- Privacy locks that are small, round thumbturns that require pinching or twisting.
- Closers that make the door too heavy for someone who is also trying to maneuver a wheelchair or walker inside the room.
- Doors that swing into the clear floor space required at the fixtures, reducing the usable area inside the room.
- Coat hooks, trash bins or baby changing stations installed where they block the latch-side clearance.
Replacing a knob privacy set with a lever set and an ADA-compliant indicator deadbolt or large thumbturn is usually a same-visit job on a standard commercial door.
Planning an Audit for a Multi-Tenant Building
In a strip center or office building with multiple tenants, responsibility for doors is often split. The landlord may control the main entrances, common corridors, and stairwells, while each tenant controls the doors inside its own suite. Before scheduling an audit, it helps to sort out who owns which doors under the lease so the report can be divided into landlord items and tenant items.
A practical approach is to start with a door list, numbered on a simple floor plan, then walk the building in the same order on every visit. Using the same door numbers from year to year makes it easy to see which doors keep drifting out of adjustment and which hardware may need to be replaced rather than readjusted again.
How Often to Recheck
There is no fixed federal schedule for rechecking ADA door measurements, but it makes sense to tie it to the way the building is used. High-traffic entrances, restroom doors and doors with closers that are frequently adjusted by staff tend to drift fastest. Many property managers find it practical to recheck these doors whenever they have other door maintenance done, and to run a full building audit after any renovation, hardware replacement or change in tenant.
Keep the old reports. A history of readings for the same door shows whether a problem is being corrected or simply readjusted and left to drift again, which is useful information when deciding whether to replace a closer or other hardware.
What to Have Ready Before the Audit
- A floor plan or site map showing public entrances, corridors, restrooms and suite doors.
- Access to every door on the list, including keys or codes for locked back-of-house areas.
- Any prior audit reports, permits or hardware schedules from a past renovation.
- A note of any doors staff have complained about, such as doors that slam, doors that are hard to open or locks that stick.
With that in hand, the audit can move quickly from door to door, and the findings can be turned into a clear list of adjustments, hardware changes and housekeeping items for the property.
