ADA Door Closer and Opening Force Rules for Commercial Doors

Under the 2010 ADA Standards, an interior hinged door on an accessible route should open with no more than 5 pounds of force, and its closer should take at least 5 seconds to swing from 90 degrees open to 12 degrees from the latch. Door hardware has to work without tight grasping, pinching or twisting of the wrist, and it belongs between 34 and 48 inches above the floor. Fire doors and exterior doors follow different numbers, and in Canada the reference points are the provincial building code and CSA B651 rather than the ADA.

The numbers that matter on an accessible door

The relevant section is 404 of the 2010 ADA Standards for Accessible Design. These are the points facility teams most often end up checking.

Opening force, 404.2.9. Interior hinged doors, sliding doors and folding doors: 5 pounds maximum, measured as a push or pull at the door. The ADA itself sets no limit for exterior hinged doors, because wind and stack pressure make a single number unrealistic. Some jurisdictions add one: California's code, for example, uses 8.5 pounds for exterior doors.

Closing speed, 404.2.8. A door with a closer must take at least 5 seconds to move from 90 degrees open to a position 12 degrees from the latch. The point is to give someone using a wheelchair, walker or cane time to get through. A door that slams shut in two seconds fails this even if it opens easily.

Spring hinges, 404.2.8.2. Doors on spring hinges instead of a closer must take at least 1.5 seconds to move from 70 degrees open to closed.

Hardware, 404.2.7. Handles, pulls, latches and locks must be operable with one hand, without tight grasping, pinching or twisting. Lever handles, push plates and pull bars pass. Round knobs and thumb latches that need a pinch generally do not. Mounting height is 34 inches minimum and 48 inches maximum above the finished floor.

Thresholds, 404.2.5. Thresholds are limited to 1/2 inch high. Changes in level between 1/4 and 1/2 inch need a bevel no steeper than 1 to 2. Existing or altered thresholds up to 3/4 inch high are allowed if they are beveled.

Fire doors play by a different rulebook

Fire-rated doors have to close and latch every time, so they need a stronger closer. The ADA recognizes this by exempting fire doors from the 5 pound limit, which leaves the minimum force to the authority having jurisdiction. NFPA 101, the Life Safety Code, caps egress doors at 15 pounds to release the latch, 30 pounds to set the door in motion and 15 pounds to swing it to full open.

NFPA 80 governs the doors themselves. It calls for fire door assemblies to be inspected and tested at least once a year, with a written record, and it limits field changes. A few practical consequences for maintenance work:

• Never add a hold-open wedge, hook or kick-down stop to a fire door. Hold-open has to come from a listed device tied to the fire alarm or a smoke detector.
• Do not drill new holes through a rated door or frame for signs, peepholes or hardware beyond what the label allows. Unused holes are typically filled with steel fasteners or the manufacturer's method, not wood filler or caulk.
• Protection plates up to 16 inches from the bottom of the door are generally allowed on fire doors. Taller plates usually need to be labeled for the purpose.
• Replacement hinges, closers and latches should be listed for use on fire doors. A residential closer or a non-latching passage set on a rated door is a common inspection finding.

When a fire door fails to latch, the cause is usually a soft closer, a sagging top hinge, a shifted strike or a rubbing gasket, all handyman-level fixes.

How Canadian buildings handle it

Canada has no single federal accessibility rule for private buildings. Accessibility requirements come from the provincial building code (Ontario's Building Code, the Quebec Construction Code, the BC Building Code and the National Building Code adopted elsewhere), and many of those codes and public-sector design standards reference CSA B651, "Accessible design for the built environment." CSA B651 covers the same ground as ADA section 404: opening force, closer timing, lever hardware, clear width and thresholds.

Exact values differ by code edition and province, so check which edition applies to each building. For fire doors, the National Fire Code of Canada and the provincial fire codes point back to NFPA 80 for inspection and maintenance, so the fire door guidance above carries across the border.

A quick door check you can run in-house

You do not need a consultant to catch most problems. An inexpensive door pressure gauge (a push-pull gauge with a flat tip) and a stopwatch on a phone cover the basics.

1. Open the door to 90 degrees and let go. Time how long it takes to reach roughly 12 degrees from the latch. Under 5 seconds on an accessible door means the closer needs adjusting.
2. Push at the latch edge with the gauge until the door starts to move and keep pushing to full open. On an interior accessible door, note anything over 5 pounds.
3. Check that the door fully latches from any open position, especially fire doors and exterior doors.
4. Look at the hardware: round knobs on accessible routes, loose levers that droop, or locks that need a twist and pinch.
5. Measure the threshold height and look for lifted or cracked edges.
6. On fire doors, look for wedges, missing labels, painted-over gaskets, holes and non-rated hardware.

Write each finding down by door number. A list sorted by floor makes the repair visit faster.

What a handyman fixes, and what goes to a trade or specialist

Most door compliance problems are adjustments and hardware swaps. A Steadle technician can typically handle:

• Closer adjustment (sweep, latch and backcheck valves) to hit closing time and latching.
• Replacing a worn surface-mounted closer with a like-for-like or listed unit.
• Swapping round knobs for lever sets that match the existing lock function.
• Tightening or replacing hinges and shimming a sagging door so it stops rubbing.
• Moving or adjusting strike plates so the door latches.
• Installing kick plates within the allowed height, and door stops and silencers.
• Replacing threshold strips and adding beveled transitions where the existing frame allows.

Some work belongs elsewhere. Power-operated doors and automatic operators have their own standard (ANSI/BHMA A156.10 and A156.19) and are usually serviced by certified technicians. Electrified hardware, access control and fire alarm releases need a low-voltage or electrical contractor. Widening an opening or replacing a rated frame is construction. The annual NFPA 80 inspection itself should be done by someone with knowledge of fire door assemblies, and many jurisdictions expect a named inspector. When an item on your list falls into one of these groups, the written quote flags it so you can route it to the right trade.

For more on fitting door work into a broader maintenance plan, see the commercial building winterization checklist, since cold weather is exactly when closers stiffen and exterior doors stop latching.

Frequently asked questions

Does every commercial door have to meet the 5 pound opening force rule?

No. Under the ADA, the 5 pound limit applies to interior hinged, sliding and folding doors on accessible routes. Exterior doors have no ADA force limit, though some state and local codes set one, and fire doors are exempt because they need enough closing force to latch.

How often should door closers be adjusted?

There is no fixed legal interval for adjustment, but closers drift with temperature, wear and tampering. Checking closing speed and latching at least twice a year, before winter and before summer, catches most problems. Fire doors also need the documented annual inspection under NFPA 80.

Can a closer be set to meet both the 5 pound and the latching requirements?

Often yes on interior doors, by balancing the spring size, the sweep and latch speeds and the backcheck. Where a door must latch against air pressure, such as a stairwell or vestibule, it may not be possible to stay under 5 pounds without a power assist or automatic operator. In that case the decision usually involves the building owner and the code official.

Get your door list handled

If your walk-through turned up closers that slam, doors that will not latch or knobs that should be levers, send the list through the quote form with door locations and a few photos. You will get a written, itemized quote that separates handyman adjustments from anything that needs a licensed or certified trade.
