What is the required clear width at a desk for wheelchair access?

ADA requires a minimum 30 in. wide knee space under accessible desks, with 27 in. of knee clearance height and 19 in. of knee depth. The wheelchair approach zone requires a 30x48 in. clear floor space adjacent to the desk. Work surface height must be 28–34 in.
