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

Same-day review for eligible expedited-permit projects

No verified standard-path permit timeline is available.

The City's own Solar Photovoltaic Streamlining Process page states SB 379 'requires... the City of Westminster... to implement an online, automated permitting platform that verifies code compliance and issues permits in real time,' and describes the SolarAPP+/Energov pathway as producing an 'auto-issued permit.'

Battery/solar incentive program on record

California SGIP - current category and budget check required

New applications and waitlist applications for ratepayer-funded SGIP budgets closed on December 30, 2025. New AB 209 applications have a June 30, 2028 deadline. The 2026 SGIP rate table publishes $3.10/W for solar and $1.10/Wh for storage in applicable Residential Solar and Storage Equity categories. Household eligibility and live budget availability vary by category and program administrator; check the official Program Metrics tracker before relying on an incentive.

Status on file: unknown. Verify current status before relying on this.

Orange County Power Authority (OCPA), the only CCA operating in Orange County, directly re-verified this session via its own homepage's 'Celebrating our member communities' listing as serving exactly four member cities: Buena Park, Fullerton, Irvine, and Fountain Valley. Westminster is not among them, so Southern California Edison (SCE) is recorded as both the distribution and generation utility.

Inspection steps

  • Schedule inspections online via the Westminster Build portal after work for that phase is complete; time frames generally aren't scheduled online, so contact the inspector between 7:30-8:30am on the inspection day to request one
  • Have the permit number(s), property address/unit, inspection type(s), contact name/phone, and any gate access code ready when scheduling
  • Keep the approved plans, inspection card, permits, and subcontractors' proof of license available at the job site, with the contractor present to meet the inspector

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.

Confidence: Medium (0.75)
