Accessible door design is an opening-level exercise. A nominal leaf width alone does not confirm compliance because hinges, stops, hardware projections, thresholds and approach clearances affect usable passage.
Quick answer
Check required clear width with the door open 90 degrees, maneuvering clearances on the approach, threshold profile, one-hand operable hardware, closing speed and applicable opening-force limits. Coordinate fire and exterior-door exceptions with local code.
Why ADA door requirements matters
Accessibility problems are difficult to fix after frames, walls and floors are complete. Early review prevents a wide door from still providing insufficient clear opening or an accessible route from being blocked by hardware and level changes.
Measure clear opening correctly
For a swinging door, clear width is measured between the face of the open leaf and the stop. Hardware and door thickness can reduce the usable dimension relative to the nominal opening.
Reserve maneuvering space
Approach direction, door swing, closer and latch side determine required clear floor space. Keep casework, columns, controls and adjacent doors out of that envelope.
Specify usable hardware
Operable parts should work with one hand without tight grasping, pinching or twisting. Coordinate lever sets, pulls, panic devices, access-control readers and mounting heights.
Balance closing with opening effort
Set closing speed and latching reliably while limiting operating force where applicable. Exterior wind, seals and fire-door functions require project-specific evaluation.
Specification checklist
| Item | Decision to record | Why it matters |
|---|---|---|
| Clear width | Measured opening at 90 degrees | Provides passage |
| Approach | Maneuvering clearance by direction | Allows operation |
| Threshold | Height and bevel profile | Limits level change |
| Hardware | Operation and mounting location | Supports usability |
| Closer | Speed and opening effort | Balances access and latching |
A practical coordination workflow
- Define performance. Record the room use, opening size, wall, rating, traffic and environmental conditions before selecting components.
- Coordinate the complete opening. Review the leaf, frame, hardware, glazing, seals and controls together. Resolve conflicts on the door schedule and shop drawings.
- Approve evidence. Check product data, test reports, labels, wiring diagrams and finish samples before fabrication.
- Commission in the field. Inspect installation, clearances, operation, latching, accessibility and control sequences before handover.
Information to send with an RFQ
Send opening-level information so suppliers can identify scope gaps before pricing:
- Applicable accessibility standard
- Door plan with approach direction
- Leaf, frame and hardware dimensions
- Threshold and floor-finish details
- Closer, seals and power-operator requirements
For imported packages, add the destination, required certificates, packing method and approval deadline.
Frequently asked questions
What is the common minimum clear door width under the ADA Standards?
The U.S. Access Board guidance describes a 32-inch minimum clear opening for covered doorways, measured as specified; verify the project jurisdiction and exceptions.
Can a threshold be one-half inch high?
New-construction thresholds are generally limited to one-half inch with bevel requirements above one-quarter inch; verify the exact profile and local adoption.
Does the five-pound opening-force limit apply to every door?
No. The Access Board guidance identifies exceptions including exterior hinged doors and fire doors; use the applicable local requirements.
