Guidance on the 2010 ADA Standards for Accessible Design

General. Where parking spaces are provided, the 1991 Standards, at sections 4.1.2 (5)(a) and (7) and 7(a), and the 2010 Standards, at section 208.1, require a specified number of the parking spaces to be accessible. The 2010 Standards, at section 208, include an exception that exempts parking spaces used exclusively for buses, trucks, delivery vehicles, law enforcement vehicles, or for purposes of vehicular impound, from the scoping requirement for parking spaces, provided that when these lots are accessed by the public the lot has an accessible passenger loading zone.

The 2010 Standards require accessible parking spaces to be identified by signs that display the International Symbol of Accessibility. Section 216.5, Exceptions 1 and 2, of the 2010 Standards exempt certain accessible parking spaces from this signage requirement. The first exception exempts sites that have four or fewer parking spaces from the signage requirement. Residential facilities where parking spaces are assigned to specific dwelling units are also exempted from the signage requirement.

Commenters stated that the first exception, by allowing a small parking lot with four or fewer spaces not to post a sign at its one accessible space, is problematic because it could allow all drivers to park in accessible parking spaces. The Department believes that this exception provides necessary relief for small business entities that may otherwise face the prospect of having between twenty-five percent (25%) and one hundred percent (100%) of their limited parking area unavailable to their customers because they are reserved for the exclusive use of persons whose vehicles display accessible tags or parking placards. The 2010 Standards still require these businesses to ensure that at least one of their available parking spaces is designed to be accessible.

A commenter stated that accessible parking spaces must be clearly marked. The Department notes that section 502.6 of the 2010 Standards provides that accessible parking spaces must be identified by signs that include the International Symbol of Accessibility. Also, section 502.3.3 of the 2010 Standards requires that access aisles be marked so as to discourage parking in them.
