ADAAG Manual

Fixed or Built-in Seating and Tables [4.32]

Scoping [4.1.3(18)]

Access is required to at least 5% of fixed or built-in seating and tables.

Seating [4.32.2] and Knee Clearance [4.32.3]

Knee space at least 27 inches high is required for a depth of 19 inches. The over-the-surface reach is limited to 25 inches if at least this much space is available below for knees and toes; (the forward seated reach may not extend beyond the toes). Maneuvering space is important where turning is required into the space.

Height of Tables or Counters [4.32.4]

Counter and table surface heights (28 to 34 inches) should be specified in consideration of the intended use. A height at the lower end of this range is generally preferable for surfaces used for extended periods of time (study carrels, dining counters, kitchen counters in dwelling units) as opposed to those used briefly or intermittently (breakroom counters, hotel room kitchenette counters). While 34 inches is the specified maximum for an accessible counter, the entire counter is not required to be accessible. A height of 36 inches, where necessary to accommodate below counter appliances, may be acceptable in limited use areas such as employee breakrooms, as long as a portion of the counter is accessible. (This is consistent with counters in business and mercantile facilities since customer use is limited to simple activities like writing checks or signing receipts.)
