Certain high-hazard construction work — trenches 5 feet or deeper requiring shoring, and construction of structures more than three stories or 36 feet high — requires the contractor to obtain what from Cal/OSHA before starting?

Explanation

Section 341(d)(5)(A) requires an annual or project permit before constructing a trench or excavation 5 feet or deeper into which any person must descend, and (d)(3)-(4) require permits for demolition of, and erection work on, structures more than 36 feet high - matching Labor Code §6500, which puts it as more than three stories high or the equivalent height. The permit exists to give the Division notice, which is why a local grading permit does not stand in for it (a): a city reviews an excavation for drainage, property and street impacts, not for worker protection. The engineer's stamp (b) and a confined space permit (c) are real documents with their own triggers, and holding either leaves the §341 permit still owed.
