Summary

Lynnwood adopts the Uniform Plumbing Code by reference under LMC 15.04.010, so any plumbing installation, alteration or repair inside this Snohomish County city needs a permit issued against that code. Permit fees are not fixed in the code itself: LMC 15.04.040 sends them to the city's separately adopted fee ordinance, calculated from the value of work as set by the building official.

As amended by the provisions of this chapter and the State of Washington Building Code Council under Chapters 51-56 and 51-57 WAC, the latest edition of the Uniform Plumbing Code (UPC) less Chapters 12 and 15 published by the International Association of Plumbing and Mechanical Officials, one copy of which, along with the State of Washington Building Code Council's amendments, shall be on file with the Lynnwood city clerk, are adopted by this reference; provided, that in the event of a conflict between the International Fire Code and the Uniform Plumbing Code, the International Fire Code shall govern. ... Section 104.5 and Table No. 104.5 adopted by this chapter are deleted and replaced with the following wording:104.5 Fees. Fees shall be set forth in a fee ordinance adopted, and from time to time amended, by the city council. Value of work shall include all costs related to construction and shall be set by the Building Official using a nationally recognized value table.

Full Breakdown

Lynnwood does not write its own plumbing code from scratch. 010 adopts the latest edition of the Uniform Plumbing Code, less Chapters 12 and 15, as published by the International Association of Plumbing and Mechanical Officials, together with the Washington State Building Code Council's amendments under WAC 51-56 and 51-57, with one copy kept on file with the Lynnwood city clerk. Where the International Fire Code conflicts with the UPC, the code expressly makes the Fire Code govern. 040, which deletes the UPC's own fee section and table and substitutes a rule that fees are set in a separate, council-adopted fee ordinance, with the value of work calculated by the building official from a nationally recognized value table rather than fixed dollar amounts printed in Title 15.

50 LMC; an appellant must claim the code's true intent was misapplied, that a provision does not fully apply, or that an equally good alternative construction method is proposed, and the hearing examiner has no authority to simply waive a code requirement. 055 adds a hardwired backup generator requirement, with battery backup and a posted placard, for any building whose entire sanitary sewer system discharges through a pump or ejector. These provisions were last consolidated by Ord. 3396 in 2021 and Ord. 3404 in 2021, which repealed the code's older, separately numbered definitions and penalty sections.

Violations & Fines

Title 15's original plumbing-specific violations and penalty section, former LMC 15.04.030, was repealed by Ord. 3396 in 2021, so plumbing work is no longer punished under its own numbered penalty clause in this title. Permit disputes instead go through the appeal path in LMC 15.04.045: a property owner or contractor who disagrees with a building official's ruling takes it to the hearing examiner under Chapter 16.50 LMC, not to a plumbing-specific hearing.

Frequently Asked Questions

Does Lynnwood require a permit for plumbing work?
Yes. LMC 15.04.010 adopts the Uniform Plumbing Code by reference, with Washington Building Code Council amendments, so plumbing installations and alterations inside Lynnwood city limits are governed by that adopted code and require a permit before work begins.
How much does a Lynnwood plumbing permit cost?
The code does not print a dollar figure. LMC 15.04.040 replaces the UPC's fee table with a rule that fees come from a separate fee ordinance the city council adopts and amends, based on the value of work as determined by the building official.
Who hears an appeal of a Lynnwood plumbing permit decision?
The hearing examiner. LMC 15.04.045 sends appeals of the building official's plumbing rulings to the hearing examiner under Chapter 16.50 LMC, and limits the examiner to correcting misapplied code intent, not waiving requirements outright.
Has Lynnwood changed the Uniform Plumbing Code's own text?
Yes. LMC 15.04.055 adds a requirement not in the base UPC: buildings whose sanitary sewer discharges entirely through a pump or ejector must have a hardwired backup generator with battery backup, a transfer switch, and a posted operating placard.
