Contra Costa County TAB & MAT FAQ
How Do Mechanical Acceptance Tests Relate to Certificates of Acceptance?
For a Contra Costa County project, mechanical acceptance testing is the field verification of specified HVAC functions. The Certificate of Acceptance records the applicable test results. They are parts of the same documentation process; a TAB report separately records air or water balancing measurements.
When Is TAB Required in Contra Costa County?
TAB requirements for a Contra Costa County project depend on the approved plans, specifications, and reviewing agency. Testing verifies actual airflow or water flow against project targets. Confirm the permitting jurisdiction: the county handles building permits for unincorporated areas and Clayton, Hercules, Lafayette, Moraga, and Orinda; other cities have separate building departments.
