# accessobstructionvalue

This code list is used in association with the Access Obstruction attribute which is present within the Building Access Location Feature Type. It provides an indicator of an accessibility obstruction that is visible from the exterior of the building. The Access Obstruction attribute can contain any combination of the ‘Other Obstruction’, ‘Ramp’ and ‘Step’ values; where more than one value is present, they will be delimited by the comma character (,). The single value of 'No Obstruction' will be used when there are no obstructions present.
