What is knee space clearance when using a hutch?

Adding a hutch to a desk does not affect knee clearance — the hutch sits on top of the desk surface and does not protrude into the knee space below the desk. ADA and ergonomic standards require at minimum 27 in. high x 30 in. wide x 19 in. deep knee clearance under the primary desk surface, which the hutch does not affect.
