Summary
Unincorporated San Benito County requires a building permit for small residential rooftop solar systems, processed through an expedited, state-mandated checklist review.
For a project complying with the checklist for a small residential rooftop solar energy system the applicant may submit the permit application and associated documentation to the county's building division by personal, mailed, or electronic submittal, together with the required permit processing and inspection fees. An application that satisfies the information requirements in the checklist, as determined by the Building Official, shall be deemed complete.

Full Breakdown
Under San Benito County Code Article X, applicants for a small residential rooftop solar energy system (10 kW AC or 30 kW thermal or less, on a single or duplex dwelling) submit a permit application and required documents to the county's Building Division in person, by mail, or electronically, along with permit processing and inspection fees. An application meeting the county's adopted checklist is deemed complete and administratively approved by the Building Official; incomplete applications get a written correction notice. Only one inspection is required unless the system fails and needs a reinspection. This applies only in the unincorporated area of San Benito County. Hollister and San Juan Bautista process solar permits under their own city codes.
Violations & Fines
Installing or modifying a covered solar system without first obtaining the county building permit is a violation subject to the Building Official's enforcement and standard permit/code-compliance remedies under Title 21.
