When Does Title 24 Section 130.1 Apply?

Permit approval requires code-compliant drawings, control specs, and final inspection testing.

Here’s a simplified breakdown of common Title 24 lighting control requirements for commercial spaces in Alameda:

What About Acceptance Testing?

You’ll need to schedule this test before or at the time of your final inspection.
