Why ADA Door Hardware Compliance Matters
Title III of the Americans with Disabilities Act requires that businesses open to the public must be accessible to people with disabilities. Door hardware is a key part of accessibility — if the door is too hard to open, has a knob that requires grasping, or doesn't allow enough time to pass through, the business isn't compliant.
Beyond moral and code obligations, ADA non-compliance creates real legal risk: lawsuits, demand letters, and DOJ complaints citing accessibility violations are common, and door hardware is one of the most frequently-cited issues. Getting it right is faster and cheaper than defending against complaints.
What ADA Requires for Door Hardware
Operating Hardware
- Operable with one hand — No required two-handed operation
- No tight grasping required — Knobs that require gripping fail this requirement; levers pass
- No twisting of the wrist — Round door knobs typically fail; lever handles, push plates, and U-shaped handles pass
- No more than 5 lbf to operate — The latch or release mechanism (separate from door opening force)
- Mounted between 34" and 48" above the floor — Standard installation heights typically comply
Opening Force
- Interior doors: 5 lbf maximum to push or pull open
- Exterior doors: 8.5 lbf maximum (Washington follows ADA; some local jurisdictions have lower limits)
- Fire doors: as low as practical — Fire-rated doors are typically heavier; ADA allows higher force but encourages minimum required
Door Closer Timing
- 5-second minimum sweep period — The closer must take at least 5 seconds from 90° open to 12° from latch
- Allows time for slower users to pass through — especially wheelchair users and people with mobility aids
Threshold & Door Width
- Threshold rises no more than 1/2" for new doors, 3/4" for existing (with bevel)
- Clear width 32" minimum when door is 90° open
- Maneuvering clearance on each side of door for wheelchair turn / approach
Common ADA Door Hardware Issues We Fix
- Round door knobs — Replace with ADA-compliant lever handles
- Door too hard to open — Adjust or replace door closer to meet force limits
- Door closes too fast — Adjust closer sweep speed to 5+ seconds
- Threshold too high — Install ADA-compliant threshold with proper bevel, or remove problematic threshold
- Storefront doors with awkward latches — Convert from twist-style to push-bar or lever-style latch hardware
- Restroom door operating hardware — Replace pinch-style locks with ADA-compliant privacy levers
- Deadbolt thumbturns hard to operate — Replace with ADA-compliant lever-style thumbturns
ADA-Compliant Hardware We Install
- ADA lever handles — Schlage ND-series with Sparta or Athens trim, Sargent 10-series, Yale 8800 series
- ADA-compliant thumbturns — Lever-style rather than traditional twist knobs
- Accessible privacy sets — For restroom doors, with emergency unlock from outside
- Push plates and pull handles — For doors where lever operation isn't ideal
- Power-assisted door operators — For doors that can't meet ADA force requirements with passive closers (we partner with auto-door installers for these)
- ADA-compliant thresholds — Beveled, low-rise, with appropriate transitions
