Are plumbing permits required from the local building official when DCA is performing a plan review and the system is registered?
This would be all liquid service or any vapor service over 2000 GWC aggregate storage. No, plumbing permits are not required for this type of system installation. However, if the project involves the installation of vapor piping inside the building, a plumbing permit is required for this piping. There is no plumbing permit required for the work outside the building where the DCA/BCS does the plan review and inspections.
