Plumbing & Gas Checklist

The following checklist contains the minimum information and details required on plumbing and fuel gas plans prior to submission for plan review. This is a basic pre-submittal checklist that is intended to expedite the plan review process by minimizing the number of required revisions. Please contact the commercial plan review staff at 804-748-1057 with any questions regarding this checklist or any other commercial permit questions.
