When do you need to install ADA compliant curb ramps as part of a pavement resurfacing project?

The US Department of Justice (DOJ) and the Federal Highway Administration (FHWA) have released new guidance on when ADA compliance curb ramps must be installed as part of pavement resurfacing projects to meet the Americans with Disabilities Act (ADA). The ADA defines pavement treatments as either “Maintenance” (that do not require upgrading) or an “Alteration” (which do require upgrading). Note that if new sidewalks are being installed, they need to have ADA compliant curb ramps.

What pavement resurfacing treatment constitutes an alteration?

An alteration is work that is a change that affects or could affect the usability of all or part of a building or facility. [1]  To eliminate confusion, the DOJ and FHWA met to produce a clear delineation of what pavement treatments are considered maintenance and what treatments are alterations, so highway agencies can know if they are required to incorporate curb ramps into a project. The table below shows which pavement treatments are considered maintenance versus an alteration. Any work listed in the alteration column must address ADA compliance regardless of who is paying for the project.
