San Ramon, CA Solar Energy: Panel Permits (2026)

Solar permitting in San Ramon is governed by California law requiring streamlined processes: AB 2188 (2015) mandated expedited permitting for small residential PV systems with checklist-based approval, and SB 379 (2022) required cities over 50,000 population to offer online automated permitting (SolarAPP+ or equivalent) by September 2023. San Ramon, with population over 85,000, has adopted automated permitting. Standard rooftop systems (under 38.4 kW AC for single-family; under 10 kW for expedited) receive same-day or next-business-day permits when submitted through the automated portal. Required documents: site plan, single-line electrical diagram, equipment specifications, structural roof verification (often a simple attestation for standard installations). Title 24 Part 6 Energy Code (effective 2020) requires solar PV systems on new single-family homes and low-rise multifamily; the 2023 update also triggers solar-plus-storage requirements for certain multifamily and nonresidential buildings. Battery storage (Tesla Powerwall, Enphase IQ, etc.) added to existing PV systems requires electrical permit and inspection. PG&E is the interconnection utility for San Ramon; systems interconnected after April 15, 2023 are subject to NEM 3.0 (Net Billing Tariff), which significantly reduces export credits compared to NEM 2.0. All permitted systems receive a building inspection covering structural attachment, conduit, electrical panel upgrades, and rapid shutdown compliance (NEC 690.12). HOAs cannot prohibit or unreasonably restrict solar under Civil Code 714. Permit fees are capped by state law at $450 for residential systems.
