Plumbing permit in Des Moines, Washington

Des Moines requires a plumbing permit for: DMMC 14.01.050(7) adopts “Chapter 51-56 WAC – Uniform Plumbing Code”, with no edition year and no edition phrase, under the chapter's general rolling clause.; NO APPLICANT-ELECTED INTERNATIONAL PLUMBING CODE ALTERNATE APPEARS in the adoption list at DMMC 14.01.050. SeaTac and Longview both publish one; DMMC 14.01.050 does not.; A SEPARATE CHAPTER GOVERNS SEWAGE DISPOSAL SYSTEMS — DMMC Chapter 14.25 SEWAGE DISPOSAL SYSTEMS CODE — which was NOT opened for this entry. On-site sewage questions are likely to sit there rather than in the plumbing adoption.; TWO EXPIRY TRIGGERS AND NO ABSOLUTE CAP, WHICH IS UNUSUAL IN THIS SET. DMMC 14.05.110(1): “Every permit issued shall become invalid unless the work on the site authorized by such permit is commenced within 180 days after its issuance, or if the work authorized on the site by such permit is suspended or abandoned for a period of 180 days after the time the work is commenced. The Building Official is authorized to grant, in writing, one or more extensions of time, for periods not more than 180 days each. The extension shall be requested in writing and justifiable cause demonstrated.” “ONE OR MORE EXTENSIONS” IS THE PHRASE TO NOTICE. Puyallup, Wenatchee and Walla Walla all add a two-year absolute limit that runs regardless of progress, and SeaTac allows a single extension only. Des Moines publishes neither an absolute cap nor a limit on the number of extensions.; THE APPLICATION HAS ITS OWN 180-DAY CLOCK, AND MISSING IT CAN COST YOU THE DRAWINGS. DMMC 14.05.110(2): “Applications for which no permit is issued within 180 days following the date of application filing shall expire by limitation, and plans and other data submitted for review may thereafter be returned to the applicant or destroyed by the Building Official.” One extension of up to 180 days is available on request with cause shown.; CONSTRUCTION HOURS PUT SATURDAY WITH SUNDAY, NOT WITH THE WORKING WEEK. DMMC 14.01.100: activities “shall be limited to the following hours: (1) Monday through Friday: 7:00 a.m. to 7:00 p.m. (2) Saturday, Sunday and Holidays: 8:00 a.m. to 5:00 p.m.” THREE CITIES IN THIS SET, THREE DIFFERENT PLACES FOR SATURDAY: Issaquah permits no nonemergency construction on weekends or legal holidays at all without an expanded work hours permit; University Place runs Monday THROUGH SATURDAY 7:00 to 7:00 with Sunday and legal holidays at 8:00 to 5:00; Des Moines gives Saturday the short day.; DES MOINES RESOLVES CODE CONFLICTS BY A DIFFERENT PRINCIPLE FROM ITS NEIGHBOURS, AND CARRYING THEIRS HERE WOULD GIVE THE WRONG ANSWER. DMMC 14.05.040: “Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern except that the hierarchy of the codes established in RCW 19.27.031 shall govern.” >>> SO THE DEFAULT IS MOST-RESTRICTIVE AND THE OVERRIDE IS A STATE STATUTE, NOT A LOCAL LIST. Pullman and Walla Walla both publish their own ordering and make the FIRST LISTED code govern — and they disagree with each other about where plumbing sits. Des Moines publishes no ordering of its own at all. RCW 19.27.031 was not read for this entry, so what that hierarchy contains is NOT asserted here.; DMMC 14.01.050 closes with a filing duty that is useful to a reader: “Not less than one copy of each such code, standards, rules, and regulations, in the form in which it was adopted, and suitably marked to indicate amendments, additions, deletions and exceptions as provided in this Title, shall be filed in the Building Official's office and be available for use and examination by the public.” Because the city adopts by WAC chapter with no edition year, that marked-up filed copy is the concrete way to see which text is actually in force.; DMMC 14.01.140: appeals go to the Hearing Examiner under DMMC 18.20.150, 18.20.160 and chapter 18.240 DMMC, and “All references to ‘board of appeals’ in any codes, standards, rules, and regulations adopted in this Title shall hereafter mean the Hearing Examiner.” THE EXAMINER'S POWER IS BOUNDED: “The Hearing Examiner shall have no authority to waive requirements of this Title.” Chapter 18.240 DMMC was not opened, so no deadline is asserted..

Also adopted and amended elsewhere in the Title: the International Property Maintenance Code (DMMC 14.05.120, not opened for this entry).. Local amendments apply — see the Des Moines overview page for the full list.

Nothing in the adoption list at DMMC 14.01.050 offers that election — it adopts Chapter 51-56 WAC, the Uniform Plumbing Code, and no alternate. SeaTac and Longview do publish an applicant-elected IPC alternate, so this is a city-by-city question rather than a Washington-wide one. Confirm with the Building Official before designing to the IPC.
