Martinez, CA Solar Energy: Panel Permits (2026)

Martinez complies with California's statewide solar streamlining laws including AB 2188 (2014) and SB 379 (2022), which require jurisdictions to adopt expedited, checklist-based permitting processes for small residential rooftop photovoltaic systems (up to 10 kW AC) and limit review to health and safety. Standard systems on compliant structures receive same-day or next-business-day over-the-counter permits through the Martinez Building Division, often via online submittal through an automated instant solar permitting platform such as SolarAPP+. Required submittals include: plans showing panel layout and attachment, a single-line electrical diagram, inverter and module spec sheets, structural attachment details, and a CSLB-licensed C-46 (solar) or C-10 (electrical) contractor listing. Inspection consists of a single site visit for most systems. Title 24 Part 6 of the California Energy Code (Building Energy Efficiency Standards) has required solar PV on most new single-family homes since January 1, 2020 and expanded to most low-rise multifamily and many commercial uses in 2023. California Civil Code Section 714 (Solar Rights Act) prohibits HOAs and local governments from adopting restrictions that significantly increase system cost (by more than $1,000 for PV or $1,000 for solar water) or significantly decrease system efficiency (by more than 10%). Permit fees for residential PV are capped by state law ($450 for 15 kW or less, plus $15 per kW beyond 15 kW, for systems on one- and two-family dwellings, indexed). Battery storage systems (e.g., Tesla Powerwall, LG Chem) installed with or after PV are handled through similar expedited review, with fire access/separation requirements under the CA Fire Code. Net metering compensation is now governed by Net Billing Tariff (NEM 3.0) for systems interconnected after April 14, 2023 through PG&E.
