How to read this guide

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.

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.

Utility and generation supplier

Utility

Southern California Edison (SCE)

SCE's own 'Incorporated Cities and Counties Served by SCE' fact sheet (updated 3/17/2025) explicitly lists 'San Dimas' by name among the cities in its service area.

Sources & confidence

Confidence: High (0.9)

Source(s): Incorporated Cities and Counties Served by SCE

Generation supplier

Southern California Edison (SCE) (utility)

Clean Power Alliance's own homepage states it serves '38 communities across Los Angeles and Ventura counties' and names each one individually via its site's community directory; San Dimas is not among the named communities. No other Los Angeles/Ventura County CCA serving San Dimas was found, so Southern California Edison (SCE) is recorded as both the distribution and generation utility.

Sources & confidence

Confidence: Medium (0.75)

Inspection steps

  • Schedule inspections through the City's online portal (Schedule Inspection tool)
  • The permit remains valid only if progress is verified by a passed inspection at least every six months

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. The page describes full-construction inspection stages (foundation, framing, etc.) in more detail than would apply to a typical rooftop PV installation, so only the generally-applicable scheduling/validity facts are recorded here.
