Building Division

Building Under Construction  

The Development Center is open for in-person services by appointment and limited walk-in service. The City has moved to an all-digital application and plan review platform. This means that we no longer accept paper plan submittals. All submittals must be done in digital format.

2019 California Building Standards Code

The City of Palo Alto has adopted the 2019 California Code of Regulations, Title 24 with certain amendments. These codes and amendments are effective on January 1, 2020. All projects submitted after January 1, 2020 must comply with the 2019 California Building Codes and the City of Palo Alto amendments. View the Inspection Guidelines.

Accessibility Plan Review Comments

Our California Access Compliance Specialist Inspectors are available to walk commercial projects prior to construction--often during the plan check process. This allows the design team additional time to address site conditions. Our goal is to help you reduce delays as a consequence of inspection corrections, prevent reinspections, and reduce job cost overruns. [Resources for Accessibility Information(PDF, 43KB)]

ISO Building Code Effectiveness Scale Rating

Insurance Office Services (ISO) collects information from communities in the United States on their adoption and enforcement of building codes. ISO analyzes the data using its Building Code Effectiveness Grading Schedule (BCEGS™) and then assigns a BCEGS™ Classification number to the community. The classification number, which ranges from 1 to 10, measures a jurisdiction's commitment to the adoption and enforcement of building codes affecting the construction of new buildings. Class 1 indicates the most favorable classification of commitment to the adoption and enforcement of building codes. The Building Division is currently classified as a 3 and the Fire Department is classified as a 2.
