How wide does an access aisle have to be?

At least 5 feet for a car-accessible stall and 8 feet for a van-accessible stall. Two stalls may share one aisle. Access aisles must be marked so they are not mistaken for parking.

What is the maximum slope for an accessible stall?

1:48 — about 2% — in all directions across the stall and its access aisle. This is the most commonly failed requirement, and it usually means regrading rather than restriping.

How high must accessible parking signs be mounted?

The bottom of the sign must sit at least 60 inches above the finished grade so it stays visible when a vehicle is parked in the stall. Van stalls need an additional 'Van Accessible' designation.

Quick Answer

How many accessible parking spaces do I need?

The 2010 ADA Standards scale with lot size: 1 accessible stall for lots of 1-25 spaces, 2 for 26-50, 3 for 51-75, 4 for 76-100, and continuing up from there. At least one in every six accessible stalls must be van-accessible.

Why Choose Professional ADA Parking Compliance?

Accessible parking is one of the most frequently cited — and most cheaply fixed — compliance failures on commercial property. The requirements are specific: a set minimum of accessible stalls based on total count, one van-accessible stall for every six accessible stalls, access aisles at least 5' wide (8' for van stalls), surface slopes no steeper than 1:48 in all directions, and signage mounted at least 60" above grade to the bottom of the sign. We audit your lot against those standards, document what fails, and correct it with striping, grinding, ramp work, and signage.
