Codes adopted
The State Building Code is in effect in every county and city in Washington, and its minimum performance standards may not be diminished locally. A local amendment that affects single-family or multifamily residential buildings is not effective unless the State Building Code Council approves it; amendments to non-residential provisions carry no such approval requirement.
LYNDEN NAMES NO EDITION FOR ANY CODE, AND ADOPTS FUTURE AMENDMENTS IN ADVANCE. Show full textShow less
LYNDEN NAMES NO EDITION FOR ANY CODE, AND ADOPTS FUTURE AMENDMENTS IN ADVANCE. LMC 15.02.010: "The city adopts the International Building Code, published by the International Code Council, as the building code of the city. The city further adopts any future amendments to the International Building Code, effective upon its adoption by the State Building Code Council." (Ord. 1195 SS A(part), 2004). The same two-sentence device is used for the International Existing Building Code (15.03.010), the International Residential Code (15.04.010), the International Mechanical Code (15.06.010), the Uniform Plumbing Code (15.08.010) and the International Fire Code (15.12.010).
- THE ENACTING ORDINANCE IS FROM 2004 AND IT STILL TRACKS THE STATE. Most of Title 15 carries "(Ord. 1195 SS A(part), 2004)". Because the adoptions were drafted to absorb future amendments automatically, a twenty-two-year-old ordinance still delivers the current state code without the council re-enacting anything.
THE ELECTRICAL CODE IS ADOPTED WITHOUT EVEN A STATE TRIGGER. LMC 15.10.010: "The city adopts the current National Electrical Code, including all appendices, as the electrical code of the city. Show full textShow less
THE ELECTRICAL CODE IS ADOPTED WITHOUT EVEN A STATE TRIGGER. LMC 15.10.010: "The city adopts the current National Electrical Code, including all appendices, as the electrical code of the city. The city further adopts any future amendments to the National Electrical Code." Note what is missing - there is no "effective upon its adoption by the State Building Code Council" qualifier on this one, unlike the building and residential adoptions.
THE ENERGY CODE CITATION IS WORTH CHECKING BEFORE YOU RELY ON IT. Show full textShow less
THE ENERGY CODE CITATION IS WORTH CHECKING BEFORE YOU RELY ON IT. LMC 15.24.010 adopts "The Washington State Energy Code contained in Washington Administrative Code Chapter 15-11, and all subsequent amendments thereto which are required to be adopted by the city". Camas's code, read on the same day, cites "WAC 51-11 energy code" for the same thing. This guide records both as published and does not adjudicate between them - ask the city which chapter it applies.
- RCW 19.27 - the Washington State Building Code applies statewide.

Tips & gotchas
- Lynden's code names NO code edition anywhere in Title 15. It adopts each code by name and takes future state amendments automatically, under an ordinance from 2004.
- THE BIG ONE: the city can require third-party review of any building permit application at your sole cost. You pay the full estimated cost as a deposit before review starts, and the city may stop work if the deposit runs out. Ask early whether your project will trigger it.
- If your building is within 400 feet of an existing sewer line, you must connect to the system - a septic plan will not get a permit.
- Both the permit fee AND the valuation schedule it is computed from are council resolutions, so neither is readable from the municipal code.
- A detached shed of 120 square feet or less needs no building permit; anything larger does, and the code says so explicitly.
- Building appeals in Lynden go to a hearing examiner under LMC Chapter 15.14.
- The electrical adoption at LMC 15.10.010 takes "any future amendments" WITHOUT the state council trigger the building and residential adoptions carry.
- Counter hours are not published on the city pages read for this entry - call 360-354-5532 before travelling.
