Overview

GridPermit collects California residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.

Permit timeline

0–3 days

The City's own page states applicants using its Symbium-based automated platform (SB 379 compliant) 'will be able to apply for instantaneous plan review approval,' while all other photovoltaic/energy storage applications submitted via e-TRAKiT are 'subject to plan review' with 'permit processing [taking] approximately 1-3 business days, depending on staff availability.' The 0-3 day range reflects instant issuance for the Symbium-eligible pathway and up to 3 business days for the standard pathway.

Directly re-verified this session via MCE's own service-area page, which explicitly lists its Solano County service as exactly four communities: Benicia, Fairfield, Vallejo, and unincorporated Solano County. Vacaville is not among them, and no other CCA was found serving Solano County. PG&E is recorded as both the distribution and generation utility.

Inspection steps

  • Schedule or cancel inspections via IVR at (707) 317-1070, SelecTXT at (866) 752-4311, or through eTRAKiT
  • The building permit, approved plans, and supporting documentation must be available to the inspector on site; no inspection will be conducted without them
  • Re-inspection fees may apply if the project isn't ready, the inspector cannot gain entry, the permit card/approved plans aren't on site, or the inspection is canceled after 6:00am

This is the City's general Building Division inspection process (the same page covers all building permit types, including solar); the City does not publish a separate, solar-specific inspection sequence.
