The Americans with Disabilities Act (ADA) provides Wheelchair Ramp Specifications, Requirements and access guidelines that most business are required to meet. Most residential applications do not need to meet ADA guidelines, requirements and specifications, but they are a good reference point for recommended ramp lengths. Contact your local building inspector for additional information.

- 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 ramp.
