When does a side sewer need a permit in City of Shoreline?
The side-sewer permit is issued by whichever utility owns the sanitary sewer — the city, a sewer or water district, or a regional utility — under that utility's own code, with WAC 51-56 (2021 UPC) governing how the building sewer is laid. WHICH UTILITY IS A PER-PROPERTY FACT: a lot can sit inside a city for permitting and outside its sewer district, so confirm the owner of the main before applying.

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.
