San Ramon, CA Solar Energy: HOA Restrictions (2026)

714. (a) Any covenant, restriction, or condition contained in any deed, contract, security instrument, or other instrument affecting the transfer or sale of, or any interest in, real property, and any provision of a governing document, as defined in Section 4150 or 6552, that effectively prohibits or restricts the installation or use of a solar energy system is void and unenforceable. (b) This section does not apply to provisions that impose reasonable restrictions on solar energy systems. However, it is the policy of the state to promote and encourage the use of solar energy systems and to remove obstacles thereto. Accordingly, reasonable restrictions on a solar energy system are those restrictions that do not significantly increase the cost of the system or significantly decrease its efficiency or specified performance, or that allow for an alternative system of comparable cost, efficiency, and energy conservation benefits. (c) (1) A solar energy system shall meet applicable health and safety standards and requirements imposed by state and local permitting authorities, consistent with Section 65850.5 of the Government Code. (2) Solar energy systems used for heating water in single family residences and solar collectors used for heating water in commercial or swimming pool applications shall be certified by an accredited listing agency as defined in the Plumbing and Mechanical Codes. (3) A solar energy system for producing electricity shall also meet all applicable safety and performance standards established by the California Electrical Code, the Institute of Electrical and Electronics Engineers, and accredited testing laboratories such as Underwriters Laboratories and, where applicable, rules of the Public Utilities Commission regarding safety and reliability. (d) For the purposes of this section: (1) (A) For solar domestic water heating systems or solar swimming pool heating systems that comply with state and federal law, “significantly” means an amount exceeding 10 percent of the cost of the system, but in no case more than one thousand dollars ($1,000), or decreasing the efficiency of the solar energy system by an amount exceeding 10 percent, as originally specified and proposed. (B) For photovoltaic systems that comply with state and federal law, “significantly” means an amount not to exceed one thousand dollars ($1,000) over the system cost as originally specified and proposed, or a decrease in system efficiency of an amount exceeding 10 percent as originally specified and proposed. (2) “Solar energy system” has the same meaning as defined in paragraphs (1) and (2) of subdivision (a) of Section 801.5.
