Do I Need a Permit for Solar Panels in Sacramento, CA?

Sacramento is an exceptional solar market for three compounding reasons: strong sun exposure with around 5.3–5.8 peak sun hours per day, SMUD's fee exemption that waives all building permit fees for residential solar, and SMUD's own net metering program that gives Sacramento homeowners significantly better export credit rates than PG&E, SCE, or SDG&E customers receive under California's NEM 3.0 policy. Building and electrical permits are required, but for most Sacramento residential installations, the SMUD fee exemption means those permits cost nothing.

Sacramento solar permit process — the SMUD fee exemption

Sacramento County Code §16.90.031 is one of California's most favorable solar permit provisions. The statute reads: "Existing residential buildings that are installing Residential Photovoltaic Solar System Projects with SMUD Interconnection Agreements shall be exempt from all Building Permit and Plan Review fees set forth in this chapter 16.90." In practical terms, this means the building permit and electrical permit for a standard residential rooftop solar installation in Sacramento's SMUD service territory carry zero in city permit fees — only SMUD's one-time interconnection fee and any contractor permit-processing fees apply.

The City of Sacramento publishes a dedicated "Guide to Solar Energy Permits" that outlines the permit sequence. The process follows four steps. First: SMUD pre-approval. The solar contractor submits a Facility Interconnection Application to SMUD, which verifies the system's shading analysis, array tilt and orientation, electrical specifications, and physical location. SMUD issues a confirmation letter or email indicating pre-approval. This happens before the city permit application. Second: city building and electrical permits. With the SMUD pre-approval confirmation in hand, the contractor applies to the Community Development Department through the Accela portal. Because fees are waived under §16.90.031, the application is submitted at no cost. Third: installation and city inspection. After permits are issued, installation proceeds. The city inspector verifies the installation meets California Electrical Code and building code requirements. Fourth: SMUD final steps. After the city inspection passes, SMUD installs the net production meter and issues Permission to Operate — the system can then be turned on.

Historic properties are the important exception to Sacramento's streamlined solar permitting. The Sacramento Guide to Solar Energy Permits explicitly states: "If a project site is located within a historic district or is located on a building/structure that is 50 years or older then preservation review will be required for all proposed solar energy systems." Sacramento has extensive historic residential stock — most homes in East Sacramento, Land Park, Curtis Park, and Midtown neighborhoods predate 1975 and many predate 1950. For these properties, preservation review adds approximately 2–4 weeks to the permitting timeline. Sacramento's preservation staff typically focus on panel visibility from the street — rear-facing and non-street-visible placements are generally approvable without conditions.

SMUD's Solar and Storage Rate — why Sacramento beats NEM 3.0

Sacramento homeowners have a significant advantage over PG&E, SCE, and SDG&E customers: SMUD is a community-owned municipal utility that operates outside the California Public Utilities Commission's jurisdiction. NEM 3.0 — which cut export credits from approximately $0.30/kWh to around $0.05–$0.08/kWh for PG&E customers — does not apply to SMUD customers. SMUD's website states directly: "SMUD is not governed by the California Public Utilities Commission. Our Board sets policy and rates for SMUD customers and the NEM changes currently proposed by the CPUC would not impact SMUD's rates."

New Sacramento solar customers go on SMUD's Solar and Storage Rate (SSR). Under SSR, excess solar production exported to the SMUD grid is credited at 7.4 cents per kWh — a retail-valued credit that carries over monthly until the annual settlement period. While 7.4 cents is lower than SMUD's pre-2022 NEM rate (which credited at full retail — typically $0.11–$0.14/kWh for Sacramento residential customers), it is substantially better than NEM 3.0's average of $0.05/kWh for PG&E customers. Customers who installed solar before March 1, 2022 remain on SMUD's original NEM rate until 2030.

SMUD is investing $25 million through 2030 specifically to accelerate battery storage adoption alongside solar. This program reflects the changed solar economics: with SSR crediting exports at 7.4 cents rather than full retail, the financial case for adding battery storage is stronger than it was in the NEM 1.0/2.0 era. Battery storage allows homeowners to shift solar production from low-value daytime hours to SMUD's Time-of-Day peak (5–8 PM daily) when electricity costs are highest, capturing savings rather than exporting at 7.4 cents. SMUD's $25M investment includes customer incentives for qualifying battery storage systems — confirm current storage incentive availability at smud.org.
