Door Closers: Types & ADA Compliance Requirements
ADA sets a specific, testable opening-force limit for interior doors — 5 pounds of force, not a general "reasonably easy to open" standard. Here's what that means for your door closer.
A door closer that's adjusted too tight isn't just an inconvenience — on an accessible route, it can be a genuine ADA compliance failure with a specific numeric threshold. This guide covers the main closer types used on commercial doors and the actual force and speed requirements that apply, not the vague version most people have heard.
Quick answer: interior hinged doors on an accessible route must open with 5 pounds of force (5 lbf) or less, per ADA §404.2.9. Exterior doors aren't directly limited by ADA but fall to the International Building Code instead — 30 lbf to start the door moving, 15 lbf to reach full open. Closers must also take at least 5 seconds to move the door from 90 degrees to 12 degrees from latched.
The actual ADA opening-force requirement
Under ADA Standards §404.2.9, interior hinged, sliding, or folding doors on an accessible route (excluding fire doors, which follow separate requirements) must be operable with no more than 5 pounds of force. This is the force needed to push or pull the door open from a closed position — it does not include whatever force is needed to operate the latch or handle hardware separately.
Exterior doors are handled differently: ADA itself doesn't specify a maximum opening force for exterior doors, so the applicable limit comes from the International Building Code instead — up to 30 lbf to set the door in motion, and up to 15 lbf to swing it to the fully open position. A closer adjusted correctly for an interior accessible-route door will often feel noticeably lighter than what people expect from a standard exterior storefront closer, and that's by design, not a sign of a weak closer.
The closing-speed requirement most people miss
Beyond opening force, ADA also requires that a door closer take at least 5 seconds to move the door from a 90-degree open position to 12 degrees from the latched position. This exists so someone using a wheelchair, walker, or crutches has enough time to clear the doorway before the door swings shut — a closer adjusted to snap shut quickly can fail this requirement even if the opening force itself is compliant.
Common commercial door closer types
- Surface-mounted closers — the most common type, mounted visibly on the door and frame, straightforward to install and adjust
- Concealed (overhead or in-frame) closers — mounted inside the door or frame for a cleaner appearance, more involved to install and service
- Floor closers — mounted in the floor beneath the door, common on frameless glass storefront doors where a visible surface closer isn't practical
Getting the adjustment right
Most commercial closers have separate adjustment valves for closing speed, latching speed, and backcheck (which cushions the door if it's opened too forcefully), plus spring tension that determines opening force. A closer that's technically ADA-compliant on force but poorly adjusted on latching speed can still slam, and one adjusted for a smooth, slow close can still fail the 5 lbf force requirement if the spring tension itself is set too high. Both need to be checked, not just one.

Frequently asked questions
How do I know if my door closer is out of ADA compliance?+
The most reliable way is a force gauge test measuring actual pounds of force needed to open the door, along with timing how long it takes to swing from 90 degrees to 12 degrees from latched. A door that feels noticeably hard to push open, or one that swings shut quickly, is worth having checked rather than assumed compliant.
Does every door in my business need to meet the 5 lbf requirement?+
The requirement specifically applies to doors on an accessible route, which generally means paths a person with a disability would need to use to access the building or its facilities — not necessarily every interior door in the building. Fire doors also follow separate requirements rather than the standard 5 lbf limit. If you're unsure which doors apply, that's worth confirming against your specific building's accessible route plan.
Can any door closer be adjusted to meet ADA requirements, or do I need special hardware?+
Many standard commercial closers can be adjusted within ADA parameters, but not all — some older or heavy-duty closers are built with minimum spring tensions above what's needed for a 5 lbf interior door. If a closer can't be adjusted down far enough, replacing it with a lighter-duty or ADA-specific model is the correct fix rather than leaving it out of compliance.
