Fee schedule
Plumbing permit
ECDC 19.70 is titled “Fees” and contains no monetary figure. Show full citationHide
ECDC 19.70 is titled “Fees” and contains no monetary figure. Its five live sections were opened in full this session: 19.70.010 states “Fee schedules are on file in the city clerk’s office.” while 19.70.010(C) and 19.70.020 both state the amounts are “set forth in this chapter” — a cross-reference that points at its own chapter and is wrong. The one pointer that leaves the chapter, ECDC 15.00.020(A), was also opened in full and ends outside the code: “Fees are established by resolution of the city council and can be accessed at the following hyperlink: Development Fees.” No dollar amount is therefore published in the Edmonds code, and none is asserted here.Set by council resolution; not in code
Inspection and reinspection
ECDC 19.70.010(C): inspection and reinspection fees must be paid prior to any inspection by city staff. Show full citationHide

Tips
- Edmonds is a Uniform Plumbing Code city, which catches people arriving from IPC jurisdictions: fixture unit tables, venting rules and sizing all differ. ECDC 19.20.000 adopts the 2021 UPC published by IAPMO including Appendices A, B, I and M, through Chapter 51-56 WAC.
- The potable water evidence requirement at ECDC 19.20.010 gates the BUILDING permit, not just the plumbing one — the building official must have substantive evidence of adequate supply from the purveyor before any permit issues for new development, and the city reserves the right to declare a moratorium regardless.
- Only two plumbing items are permit-exempt under ECDC 19.00.025(G)(3): stopping leaks in drains, water, soil, waste or vent pipe, and reinstalling or replacing approved prefabricated fixtures that do not require valves or pipes to be replaced or rearranged. Even the leak exemption requires new material, a permit and an inspection where defective material is replaced.
