Redmond issues streamlined solar permits for rooftop PV systems through Development Services. Permits require electrical and structural review and follow the WA State Energy Code.
Residential and commercial rooftop solar photovoltaic systems in Redmond require an electrical permit and typically a building permit or simple structural review through Redmond Development Services. Redmond follows the Washington State Energy Code under RCW 19.27A, the International Residential Code, and the National Electrical Code. Most homeowner residential solar installs on existing roofs under 10 kW on a single-family house qualify for a streamlined or over-the-counter permit path. Structural review confirms the existing roof can handle the added load and any mounting rails. Ground-mounted solar arrays in the back or side yard require a separate zoning and structural review and must meet setbacks, height, and lot-coverage rules. Interconnection to the grid is coordinated with Puget Sound Energy, which must approve a net-metering agreement before energizing the system. Solar water heating and solar-ready wiring in new construction are encouraged under the state Energy Code.
