Final Inspection Failures: What Inspectors Look for in Title 24 Lighting Tests

Title 24 lighting inspections are one of the most important—and most stressful—steps in closing out a project. Inspectors have clear expectations when they walk onto a job site, and understanding these expectations can mean the difference between passing on the first try or facing expensive delays.

What Inspectors Check First

Inspectors always begin by verifying documentation. If the NRCA forms, compliance paperwork, or control narratives are missing, the inspection ends immediately. Complete documentation sets the tone for the entire inspection.

Functional Testing Requirements

Inspectors don’t take your word for anything—they test everything. This includes:
• Occupancy and vacancy sensor activation
• Time-out delay adjustments
• Daylighting sensor response
• Multi-level lighting functionality
• Demand-response system readiness
• Exterior lighting shutoff controls

If any of these fail, the inspection does not continue.

Common Causes of Final Inspection Failures

• Sensors installed but never programmed
• Controls set to “manual on” when “auto on” is required (or vice versa)
• Uncalibrated daylighting systems
• Exterior lights not shutting off automatically
• Incorrect fixture wattage or model numbers
• Plug-load circuits not tied to the control system

Even the smallest issue can lead to a failure.

How to Ensure a First-Time Pass

The best way to pass a final inspection is to perform acceptance testing before the inspector arrives. A certified Title 24 lighting acceptance testing technician ensures that:
• All systems are properly set up
• Paperwork is complete
• All controls function according to code
• Potential problems are corrected in advance

This eliminates surprises and keeps your project on schedule.
