Notes & caveats
Woodinville's exempt list (WMC 21.62.070) replaces the IRC's Building items with the City's own and names no solar installation, and the IRC the City adopts regulates rooftop solar (R324, WMC 21.62.010), so the racking and roof attachment need a City building permit. The array's wiring, inverter and connection need an L&I electrical permit and inspection.
