The Fire Dept Plan Check is requiring an updated Use and Occupancy Plan for a Semi-Conductor facility , three Stories, 270,000 sf and permitted with the 1985 Cal Bldg Code. The original Occupancy Classes are H-1 thru H-7, but these are no longer applicable since the H Occp were updated, I think 1998? I'm needing to cross-reference the current 2022 CBC H Occupancy Classifications (H-1 thru H-5) with the older Classifications (H-1 thru H-7). No luck getting older Codes online. Can anybody please lay out that comparison?
