ADA Modular Wheelchair Ramp Specifications

The Americans with Disabilities Act (ADA) provides Wheelchair Ramp Specification and access guidelines that most business are required to meet. Most residential applications (please see out residential or light commercial modular wheelchair ramp) do not need to meet ADA guidelines, but they are a good reference point for recommended ramp lengths.  Most businesses, churches, schools and other organizations must comply with ADA Specifications and ADA guidelines for handicapped wheelchair ramp access. Contact your local building inspector for additional information.

• ADA Requires a 1:12 slope ratio which works out to be one foot of wheelchair ramp for each inch of rise. For instance, a 20 inch rise requires a 20 foot wheelchair ramp.
• ADA Requires a Minimum 5’ x 5’ Flat area at the top and bottom of the ramp.
• ADA Requires a Minimum 36 inches of clear space across the wheelchair ramp.
• ADA Requires a Minimum Platform size is 5’ x 5’
