When do I need to do the work?
If you repave or alter the parking lot, you must add as many accessible parking stalls as needed to comply.
If you re-stripe the parking lot, you must re-stripe so that you provide the correct number of accessible stalls.
How many accessible stalls do I need?
The guidelines for the number of stalls is as follows:
# of parking stalls # accessible stalls 1 to 25 1 26 to 50 2 51 to 75 3 76 to 100 4 101 to 150 5 151 to 200 6 201 to 300 7
The first accessible stall must be a van accessible stall. One out of every eight stalls thereafter must be van accessible.
What do the accessible stalls look like?
Van accessible stalls
- the accessible stall must be at least 8 ft wide
- there must be an access isle beside the stall at least 8 ft wide.
- the stall and the access isle must be level (less than 2% grade) both from side to side and fore and aft.
- two accessible stalls may share an access isle.
- there must be at least 98" vertical clearance along the vehicular route to the accessible stall.
- there must be a sign in front of the stall indicating that it is an 'accessible' stall with the words 'van accessible' underneath. The bottom of the sign should be at least 84" above grade so as to be visible over the vehicle.
Automobile accessible stalls
- the accessible stall must be at least 8 ft wide.
- the access isle need only be 5 ft wide.
- the bottom of the sign in front of an automobile must be visible over the vehicle.
What are the practical considerations for making my parking lot more ADA compliant?
- when leveling a portion of an existing asphalt parking lot, consideration must be given to the 'transition areas' that will surround the new stalls. Significant changes in elevation require more extensive transition areas so as not to create new trip hazards.
- Asphalt is not a material that can be finely sculpted. Installation of concrete accessible stalls provides a more controllable process and long-lasting product. Unfortunately, it is often more expensive.
- when checking the grade on an accessible stall, make sure to utilize a 4 to 8 foot digital level. Shorter levels can provide distorted results.
How do Customers get from the accessible stalls to my place of business?
- the accessible stalls should be located so as to provide the shortest accessible route of travel to an accessible facility entrance.
- there must be a minimum 36" clear width access route from the access isle beside the parking stall to the accessible facility entrance.
- if the access route crosses an area of vehicular traffic, a designated crosswalk should be provided.
- if an access route crosses a curb, a curb ramp must be used. A built -up ramp must not extend into the access isle. The angle of the ramp must not exceed 5% grade with a maximum 2% cross slope.
- if an accessible route has a running slope of more than 5%, it is considered a ramp. The maximum grade of the running slope for new ramp construction is 8.33%
- If the curb ramp has flared sides, the grade of the flares shall not exceed 10%.
- If the sides of the ramp are taller than 6", railings must be provided.
- if a ramp changes direction at a landing, the minimum landing size shall be 5ft x 5 ft.
- detectible warnings (tactile strips) must be placed at all public streets and signalized intersections. The preferred color of the detectible warnings for use on concrete sidewalks is red.
