ADA Door Hardware Inspection: Pass/Fail Criteria, Force Testing & Audit Checklist
What Is the ADA Opening Force Limit for Doors?
Answer: ADA §404.2.9 sets a maximum of 5 lbf for interior hinged, sliding, and folding doors. This limit does not apply to fire doors — those are governed by NFPA 80. ICC A117.1 §404.2.9 carries the same fire-door exception. A door with a self-closer but no fire-rating label is subject to the 5 lbf limit.
How Do You Measure Door Opening Force?
Answer: Use a calibrated force gauge (lbf) — mechanical spring scale or digital model. Position the gauge perpendicular to the door face at the latch edge, 34–48 inches above the finished floor. Apply steady force to open the door and record the peak reading. Take three readings; record all three. Common field gauges: Chatillon DFE-005, Extech 475044, Mecmesin AFG-50N. Smartphone apps do not produce valid force measurements for auditable records.
What Is the ADA Closing Speed Requirement?
Answer: ADA §404.2.8 requires the door to take at least 5 seconds to travel from 90° open to 12° from the latch. Time it with a stopwatch. Slower is compliant. Faster than 5 seconds is a violation. Check the door with a closer, not a spring hinge only — the 5-second standard applies to the full closing device.
What Is the Minimum Clear Width for an Accessible Door Opening?
Answer:
- 32 inches minimum — measured from door face to latch-side stop, door at 90°
- 36 inches required if doorway depth exceeds 24 inches
- 32 inches applies to one leaf of a double-door assembly
Who Can Perform an ADA Door Inspection?
Answer:
- California: Certified Access Specialist (CASp) — CA Gov Code §4459.5. Only CASp reports trigger the SB 1608 90-day litigation stay.
- Texas: Registered Accessibility Specialist (RAS) — licensed by TDLR.
- National: ICC-certified Accessibility Inspector (AI) or architect of record for DOJ transition-plan purposes.
Quick Pass/Fail Reference Table
| Parameter | Code Reference | Pass | Fail |
|---|---|---|---|
| Clear opening width | ADA §404.2.3 | ≥ 32.0 in (or ≥ 36.0 in if depth >24 in) | Below minimum |
| Opening force (non-fire door) | ADA §404.2.9 | ≤ 5.0 lbf | > 5.0 lbf |
| Closing sweep time | ADA §404.2.8 | ≥ 5.0 sec (90° to 12°) | < 5.0 sec |
| Threshold height (beveled) | ADA §404.2.5 | ≤ ¾ in total; ≤ ½ in vertical | Either exceeded |
| Handle height | ADA §309.4 | 34–48 in AFF | Outside range |
| Handle operability | ADA §404.2.7 | Lever, loop, or push hardware | Round knob or pinch-grip latch |
11-Point Audit Checklist (Quick Reference)
- Clear width at 90°
- Maneuvering clearance — latch side
- Maneuvering clearance — hinge side (if required)
- Threshold height
- Hardware operation — handle type and height
- Opening force measurement (3 readings)
- Closing sweep timing (2 readings)
- Latch engagement (no secondary push required)
- Vision lite / kickplate (if required by occupancy)
- Hardware reach range and protrusion into circulation path
- Fire door label inspection (rated assemblies only)
Common Findings and Remediation Cost Summary
| Finding | Remediation | Typical Cost |
|---|---|---|
| Opening force >5 lbf | Adjust or replace closer (dormakaba, LCN, SARGENT) | $50–$900 per door |
| Closing sweep <5 sec | Adjust sweep valve | $50–$150 per door |
| Clear width insufficient | Swing-clear hinges (Waterson, Hager, Stanley, Allegion) or frame widening | $150–$8,000+ |
| Threshold height violation | ADA beveled threshold (Pemko, Reese) or concrete ramp | $80–$400 per opening |
| Round knob hardware | Replace with lever (Allegion Schlage, dormakaba, Waterson) | $75–$300 per door |
| Latch fails to engage | Adjust strike plate; replace latch; slow closer | $60–$250 per door |
Documentation: What to Keep and Why
Retain indefinitely: Signed audit report, individual door data sheets (measured values for all 11 points), force gauge calibration certificates, GPS-tagged photographs, remediation work orders with completion dates, and re-inspection records after remediation.
Why it matters: In Chapman v. Pier 1 Imports (9th Cir. 2011), documented good-faith barrier-removal efforts materially changed the litigation outcome. The ADA requires good faith, not perfection — but good faith must be documentable.
