City of Kennewick issued the following announcement on June 12.
Under Governor Inslee’s Phase 2 reopening plan, certain businesses can reopen but at reduced capacity. If your business has a posted occupant load, or a Certificate of Occupancy indicating your occupant load, use that to determine the reduced capacity per the order.
If your business does not have a posted occupant load and is trying to determine what the occupant load is in order to comply with the reduced capacity requirements, please review information listed below..
If you have access to the permit or design plan documents for your business, the front page of the documents typically contains occupant load calculations. If you do not have access to the permit or design documents, the following may help you determine the occupant load.
