Accessibility is a route. Not a symbol.
An accessibility symbol on a plan does not explain how someone arrives, enters, moves through the building, or uses its spaces. A useful review follows that experience and checks the conditions along it.
One journey.
Connected checks.
Review the transition between spaces, not just the spaces themselves.
- Arrive
- Site arrival points and the route to the entrance
- Enter
- Clear opening and maneuvering space
- Move
- Route continuity and changes in level
- Use
- Clear floor space, reach, and operable parts
Resolve scope before dimensions
The federal ADA Standards include scoping provisions that determine which spaces and elements must be accessible, and technical provisions that describe how they must be designed. Establish the applicable requirements for the facility and work being performed. Also identify applicable state and local requirements; an ADA review is not a substitute for reviewing the adopted building code.
Follow the accessible route
Review the connection from applicable site arrival points to the entrance, and from the entrance to the required spaces and elements. Look beyond a line drawn through the plan: changes in level, slopes, obstructions, doors, and the use of adjoining spaces affect the actual route. Coordinate the site plan with floor plans and details so the route does not disappear at a sheet boundary.
Check the opening, then the approach
Under §404.2.3 of the 2010 ADA Standards, the general minimum clear door opening is 32 inches, with stated exceptions and additional conditions. For a swinging door, the measurement is taken with the door open 90 degrees, between the face of the door and the stop. The nominal leaf size is not the clear opening. Maneuvering clearances are a separate check under §404.2.4 and depend on the approach and door condition.
Ask for the evidence the check needs
A door schedule can establish a leaf size without establishing the available approach space. Review dimensions, swing, adjacent walls, hardware notes, and the applicable detail together. Where the necessary information is absent, record the missing evidence rather than guessing that the condition passes or fails.
- Route: plan continuity, dimensions, elevations, and slope information.
- Doors: clear opening, approach, swing, and relevant hardware conditions.
- Rooms: required clear floor space, turning space, and fixed-element locations.
- Details: mounting heights, reach conditions, and the relevant specifications.
Keep the review specific
Write a finding that another person can locate and resolve: the element, the sheet and detail, the applicable requirement, what the drawing shows, and what needs clarification. Avoid a blanket “ADA compliant” conclusion from a handful of checks. Drawing review, field conditions, and the applicable legal obligations are not the same thing.
