Title 24 lighting acceptance testing
Lighting controls field testing and NRCA paperwork for nonresidential projects. Everything your inspector needs to sign off.
What we test on site
California Title 24, Part 6 requires field verification that installed lighting controls operate correctly before a nonresidential project can receive final approval. As a NLCAA-certified Acceptance Test Technician, I perform on-site Title 24 acceptance testing per Reference Nonresidential Appendix NA7.6 procedures.

Title 24 paperwork you get
Every project includes the compliance documentation your inspector and the CEC require:
- NRCA acceptance certificates — completed, signed PDF copies for your records and city submittal
- NRCI install form coordination — prepared when required; installing contractor signs as responsible person
- Electronic submission to the CEC — via NLCAA acceptance testing software with provider-branded forms
- San Francisco Final Compliance Letter — when required by DBI for Certificate of Occupancy
Third-party Title 24 testing
Mesa Construction, Inc. is registered as a third-party Acceptance Test Employer (ATE #ATE-2608-00005).
