Fee schedule
LSMC 14.80.040: “The City shall collect fees for all services rendered and activities performed in reviewing and issuing building permits. Show full citationHide
LSMC 14.80.040: “The City shall collect fees for all services rendered and activities performed in reviewing and issuing building permits. Said fees shall be set by resolution.” No dollar amount appears in the code and none is asserted here. Across this Washington set the INSTRUMENT varies and is worth knowing: Edmonds and Lake Stevens use a council RESOLUTION, Lynnwood a fee ORDINANCE, and Puyallup an EXECUTIVE ORDER of the city manager. Ask the city for the current resolution.Review timeline
Inspection process
Tips
- Two local exemptions are worth checking before you file. Lake Stevens added IRC R105.2 items 11 and 12: light-weight roof or reroof covering where the installed unit is under four pounds per square foot, and replacing exterior windows in existing openings provided the opening is not resized and the operable opening is not reduced. Both are common jobs that need no permit here.
- Sequence the sewer permit first. LSMC 14.80.050 will not let a building permit issue for a primary use structure until you have the sewage disposal permit under Chapter 14.60, so filing them together does not help — one gates the other.
- Frost line depth here is 12 inches, against 18 inches in both Edmonds and Lynnwood. If you are carrying a foundation detail across the county line this is the figure that changes, and it is set in the city's own amended Table R301.2(1).
