ADA Unit

The ADA Unit is part of Street Department’s Highway Division. The Unit is responsible for reviewing and upgrading curb ramps within the Public Right of Way to provide better access to the pedestrians. The ADA unit is also responsible to enforce the requirement to upgrade curb ramps to the most current ADA standards for all new construction within the Right of Way.

The Unit also ensures that all the curb ramps built within the Right of Way meets current Federal and State ADA requirements. In addition, the City of Philadelphia and PennDOT have worked together and established an ADA Guidance document to help design and construction professionals obtain approvals for their proposed designs and final construction. ADA Curb Ramp designs must meet the current applicable design standards and are subject to Streets Department approval through the ADA Unit.

Please contact the Streets Department ADA Coordinator at: [email protected] or 215-686-5511 if you have any questions regarding ADA Curb Ramps.
