Bellevue requires electrical and building permits for rooftop solar installations. Most residential systems qualify for expedited review under SolSmart guidelines.
Bellevue follows the Washington State Building Code (IRC and IBC) and requires both a building permit and an electrical permit for most solar photovoltaic (PV) installations on residential and commercial properties. Residential rooftop systems typically qualify for expedited over-the-counter review when the array is less than 10 kW and the roof structure is not modified. Plans must show panel layout, mounting details, weight loading (typical is 3 to 5 psf added), inverter location, and conduit routing. Structural review may be required for roofs over 20 years old. Licensed contractors pull permits through MyBuildingPermit.com. Washington State sales tax exemption under RCW 82.08.963 applies to qualifying systems under 100 kW. Interconnection with Puget Sound Energy is handled separately through PSE's net metering program. Bellevue does not limit solar panel visibility on main roof planes for single-family homes. Ground-mounted systems require Land Use Code setback compliance and may need Design Review in some districts. Call Development Services at 425-452-6800 for current submittal requirements.
