We make sure the establishment is constructed/remodeled as specified in the approved plan and that all conditions in the approval letter are met. Have everything on, at temperature, setup, and surfaces finished as though you are going to serve your first customer the moment the inspector leaves. There should be no equipment missing, not hooked up, or construction going on still. Use the preopening checklist to make sure you have everything in place. The checklist is contained within the plan review application.
