ADA Compliance
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 LotMinimum # of Accessible
Spaces Required
Of Those, # Required

 1-25 1 1
 26-50 2 1
 51-75 3 1
 76-100 4 1
 101-150 5 1
 151-200 6 1
 201-300 7 1
 301-400 8 1
 401-500 9 2
 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

 

II. Layout

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
