We also hold a T1-Annual Trench/Excavation Permit (#616505) * with the State of California Department of Industrial Relations, Division of Occupational Safety and Health (OSHA). Not all plumbing contractors have this permit, which is required by some counties and cities in the San Francisco Bay Area when digging more than 5 feet deep.
A “T1 Annual Trench Excavation” permit is a permit from the California Division of Occupational Safety and Health (CAL/OSHA) that allows an excavation to be made for an underground utility.
