Summary
HOAs in Sunnyvale cannot prohibit rooftop solar under California Civil Code 714 (Solar Rights Act). Reasonable aesthetic rules are allowed only if they do not significantly reduce performance or raise cost.
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.
(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.
Full Breakdown
California Civil Code 714, the Solar Rights Act, preempts HOA rules that prohibit or materially restrict solar energy systems on owner-occupied property. An HOA may adopt reasonable architectural guidelines, but any restriction that increases system cost by more than about $1,000 or decreases output by more than roughly 10 percent is considered unreasonable and void. Civil Code 714.1 further limits what HOAs can impose on common-area shared solar for townhomes and condos. Sunnyvale does not add stricter rules. An HOA has 45 days to approve a complete solar application, after which it is deemed approved. Owners who believe their HOA is violating 714 can file complaints with the HOA board, seek mediation, or pursue civil enforcement including attorneys' fees if they prevail.
