The Americans with Disabilities Act (ADA)
ADA is Federal Law that provides Wheelchair Ramp Specifications and guidelines that most business must meet or risk penalties and legal action. Penalties for violating ADA requirements can be up to $5000 per violation with no warning. Typically, residential applications are not required to comply with ADA guidelines. However, they are a good reference point for suitable ramp lengths. Contact your local building inspectors for local requirements and additional information.
