Reg 4 compliance is not optional. The Los Angeles Fire Department (LAFD) conducts inspections—often without notice—to confirm that required testing has been completed and properly documented. Buildings found to be out of compliance may face significant fines, enforcement actions and potential shutdowns until deficiencies are corrected, re-inspected, and approved.

We provide comprehensive Chief’s Regulation 4 testing services in accordance with LAFD requirements, including proper testing procedures, detailed documentation and clear reporting. Our sprinkler fitters are experienced with the specific expectations of Los Angeles authorities and ensure that all required systems are thoroughly and accurately evaluated.
