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.
