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.

Permit timeline

0–3 days

The City's own page states: 'automated plan review with approvals issued in as little as 24 business hours for eligible projects.' Recorded as 0-3 calendar days to conservatively bound '24 business hours' (roughly 3 business days at a standard 8-hour business day) without asserting same-day issuance as guaranteed.

Battery/solar incentive program on record

My Energy Optimizer Partner+

SMUD's own battery storage incentive program (separate from the CPUC/IOU-administered SGIP, which does not apply to SMUD customers as a municipal utility outside CPUC jurisdiction). One-time enrollment incentive of up to $10,000 per household ($500/kWh minus a 20% holdback) for new battery energy storage system customers who enroll within 90 days of receiving Permission to Operate (PTO) from SMUD. Ongoing quarterly incentives are currently only available for Tesla batteries ($110 for 1 battery, $220 for 2, $330 for 3+); other eligible brands (Eguana, Enphase, Franklin, SolarEdge, Sonnen) receive only the one-time enrollment incentive at this time.

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

    The City's own page states: 'Application fee waived: The eTRAKiT application fee is no longer required.'

  • Plan check fee: $0 (waived)

    The City's own page states: 'Plan check fees waived: Automated compliance checks eliminate traditional plan review costs.'
