The department of planning and building shall adopt an administrative, nondiscretionary expedited review process for small residential rooftop solar energy systems, including standard plans and checklists... Applications for small residential rooftop solar energy systems shall be administratively reviewed and approved by the chief building official at nondiscretionary permits within in a reasonable time following receipt of a complete application... Approval of an application for a small residential rooftop solar energy system shall not be based or conditioned on the approval of an association.
Full Breakdown
Under Chapter 19.09, the county's Department of Planning and Building must use an administrative, nondiscretionary expedited review process for small residential rooftop solar systems (10 kW AC or less, or 30 kW thermal, on a single or duplex dwelling). Applications can be submitted electronically with e-signatures, and the chief building official approves complete applications administratively rather than through a discretionary hearing. Only one inspection is required unless the system fails it. A plot plan or site plan under Title 22 or 23 is only triggered if staff find substantial evidence of a specific, adverse public health or safety impact.
Violations & Fines
An application deemed incomplete gets a written correction notice listing every deficiency; the county cannot condition approval on HOA sign-off, and approval does not authorize grid interconnection, which the applicant must arrange separately with the utility.
