Accessibility Plan Review Comments

The City of Palo Alto offers the services of our California Access Compliance Specialist Inspectors to walk commercial projects prior to construction--often during the plan check process. This allows the design team additional time to address site conditions, preventing delays at the end of the construction phase, when the owner is eager to move into their new space. Our goal is to help you reduce delays as a consequence of inspection corrections, prevent reinspections, reduce job cost overruns, and ameliorate accessibility lawsuits.
