At what depth does CalOSHA start to require shoring for trenches?

Typically, at 3 feet, the excavation should be inspected by a competent person to see if hazards exist. At 5 feet, CAL OSH requires a permit if workers will enter the excavation. This will require that excavations 5 feet or more be protected from collapse. This may be done by sloping, shoring, or shielding- or by a system designed by a Registered Professional Engineer (PE). Excavations greater than 20 ft in depth will be protected by a system designed by a PE.
