The Americans with Disabilities Act was introduced in the 1990s and created a federal mandate for accessible parking (handicap spaces) at public buildings among other things. This has been good for the pavement industry because it supersedes local regulations and makes a uniform code throughout the country.
Simply put, the ADA code is as follows:
I. Number of accessible spaces required for commercial properties, open to the public.
|# of Spaces in Lot||Minimum # of Accessible
|Of Those, # Required
to be Van Accessible
|501-1000||2% of total||1 in every 8 accessible spaces|
|1001 & Over||20 plus 1 for each 100 over 1000||1 in every 8 accessible spaces|
Accessible space – 8′ with 5′ hashout on left side
Two spaces can share a hashout
Van Accessible – 8′ space with 8′ hashout on right side
Accessible – Regular handicapped sign – Reserved parking and universal logo in center of each sign
Bottom of sign must be between 4′ and 7′ above surface
Van accessible – Same as above, except that the words “VAN ACCESSIBLE” shall be printed below the logo.
Spaces, access aisles, loading zones shall have maximum slope at 2% in all directions
