When are customer sales and service counters required to have knee clearance?  


The key term used in CABO/ANSI 4.31 is "seating". Knee clearance is required when accessible customer seating is provided. Each space must be assessed for use to determine if a person would be "seated" at the space. Consideration should be given to the amount of time spent at the space using the surface top for working, eating, writing, etc. When the expectation is that the user will be spending an appreciable amount of time at the space, knee clearance should be provided.

Approved by Building Codes and Standards Access Committee January 9, 1997.
