Bellevue FAQ
Seattle FAQ
How long does it take to get a solar panel permit in Seattle?
Standard residential rooftop solar systems qualify for expedited over-the-counter permit review at SDCI, which can often be completed in a single visit. More complex installations such as ground-mounted arrays or commercial systems require standard plan review, which takes longer depending on current processing times.
Do solar panels affect my property's lot coverage or height limits?
No. Solar panels are excluded from lot coverage calculations, and panels that do not extend more than 4 feet above the roof surface are exempt from height limit calculations. This makes it easier to add solar to existing homes without triggering zoning issues.
