Lynnwood, WA Solar Energy: Panel Permits (2026)

Table 3.104.160 LMC, adopted under LMC 3.104.160 'LMC Title 16 fees and charges,' sets Lynnwood's building, single-family, electrical and grading permit fees for construction valued under the International Code Council Valuation Data Table or the International Building Code's square-footage method, whichever is greater. For solar work, the table carves out a specific note: 'For single-family residential solar energy systems, valuation shall be based on structural components and labor only,' which keeps the taxable job value, and therefore the fee, from ballooning with the retail cost of panels and equipment.

Under that valuation rule, a single-family system that follows the city's standard 'permitting checklist' is charged a flat $228.00 fee rather than being run through the sliding valuation table used for other construction. A single-family or commercial solar installation that does not meet the permitting checklist requirements is instead charged a fee based on the building permit valuation table, the same tiered schedule used for ordinary building permits, which starts at $114.00 for jobs valued up to $2,000.00 and rises with construction value. This fee schedule governs the permit charge only; it sits alongside, and does not replace, Washington's State Building Code adopted under Chapter 19.27 RCW, which supplies the underlying construction standards a solar installer must still meet for structural attachment and electrical work.
