Washington County requires permits for residential solar installations under the Oregon Solar Installation Specialty Code. Most systems qualify for prescriptive (expedited) solar permits via the county's Building Services division and ePermitting.
Solar PV installations in unincorporated Washington County require a structural/prescriptive solar permit and a separate electrical permit through Building and Development Application Services (BDAS). Oregon uses the 2017 Oregon Solar Installation Specialty Code and prescriptive path under OAR 918-311. Most standard rooftop systems under the prescriptive limits (panel weight, roof pitch, wind/snow loads) do not require stamped engineering. Plans submit through ProjectDox. Fire setbacks follow Oregon Fire Code Section 1205: 18-inch pathways along roof ridges and 36-inch access for firefighters on hip roofs. Net metering is provided by PGE and Portland General Electric under Oregon Public Utility Commission rules. CDC 427 (Solar Access Standards) preserves solar access for lots in new subdivisions. Hillsboro, Beaverton, and Tigard each issue permits under the same statewide Oregon Solar Specialty Code.
Installation without permit: stop-work order, retroactive permit with investigation fee (typically 2x permit fee). Failed electrical inspection: correction notice. Utility interconnection missing: system must remain off-grid until PGE/PacifiCorp completes PTO.
