Notes & caveats
Issuing body is the sanitary sewer utility, NOT the building department, and inspection is the utility's too. SOME utilities additionally require the contractor to hold a side-sewer card or registration before they will issue; it is not universal, so check the serving utility's own rules rather than assuming either way.
