California Solar Rights Act: HOA Limits and Enforcement

The California Solar Rights Act, found at Civil Code Section 714, blocks HOAs, deed restrictions, and local governments from effectively preventing a homeowner from installing a residential solar energy system. Any restriction that adds more than $1,000 to a photovoltaic project or cuts its efficiency by more than 10% is void and unenforceable. If an HOA or private entity willfully violates the law, the homeowner can sue for actual damages plus a civil penalty of up to $1,000, and the prevailing party recovers reasonable attorney’s fees.¹

What Systems and Property the Law Covers

The Act applies broadly. Through Civil Code 801.5, “solar energy system” includes solar collectors for electricity, water heating, space heating, or space cooling, along with structural features like solar carports, shade structures, awnings, canopies, and patio covers. Building-integrated technology also qualifies, including solar windows, siding, and roofing tiles.²

To receive the law’s protection, the system has to meet state and local health and safety standards. Photovoltaic systems must comply with the California Electrical Code and carry certification from an accredited testing laboratory. Solar water heating systems for single-family homes and pool heating collectors must be certified under the Plumbing and Mechanical Codes.¹

The Cost and Efficiency Limits That Make a Restriction Illegal

Section 714 voids any restriction that “significantly” increases cost or decreases efficiency, and the statute defines “significantly” with hard numbers.

For photovoltaic systems, a restriction is unreasonable if it adds more than $1,000 to the cost of the system as originally proposed, or if it reduces efficiency by more than 10%. The $1,000 ceiling is flat, no matter how large the system.

For solar water heating and pool heating systems, the cost line is a cost increase above 10% of the system’s price, capped at $1,000. So a $5,000 pool heating system can absorb no more than $500 in added cost before the restriction becomes unreasonable; a $15,000 system hits the ceiling at $1,000. The 10% efficiency limit applies either way.¹

A restriction can still be upheld if the HOA offers an alternative system with comparable cost, efficiency, and energy conservation benefits. An HOA could, for example, require a different panel placement, provided the alternative performs just as well and doesn’t cost meaningfully more.

What an HOA Can and Cannot Require

HOAs keep some oversight, but the limits in Civil Code 714.1 are strict.

An HOA cannot adopt a blanket ban on rooftop solar for the building where the owner lives, or on a garage or carport assigned to that owner. It also cannot require a vote of the membership to approve a rooftop installation. Any provision doing either is void.³

What an HOA can do under 714.1:

Limit common-area installations to systems the HOA has approved.
Require the consent of another owner before you install on their separate interest.
Include provisions that preserve the HOA’s ability to maintain, repair, or replace roofing and building components.
Require the installing owner to indemnify the HOA for damage caused by the installation, maintenance, or use of the system.

Condos and Shared Roofs

If the roof is a common area shared with other units, Civil Code 4746 layers on extra requirements. The owner installing panels has to notify every other owner in the building, carry homeowner liability insurance for as long as the system is in place, and provide a certificate of insurance within 14 days of approval and annually afterward. The HOA can also require a solar site survey by a licensed contractor to identify usable roof area and allocate space equitably among owners who share the roof. The cost of that site survey does not count toward the $1,000 cap in Section 714.⁴

What a City or County Can Review

Government Code 65850.5 restricts local permit review to health and safety compliance. A building official cannot refuse a solar permit on aesthetic grounds or neighborhood character, and cannot condition a permit on HOA approval.⁵

For small residential rooftop systems, every California city and county must maintain an expedited permitting process built around a published checklist. Once your application meets every item on that checklist, the local government must approve it and issue the required permits. The checklist and application must be available online, and electronic submission with electronic signatures must be accepted. Only one inspection is required for small rooftop systems that qualify for expedited review, though a follow-up inspection is allowed if the first one fails.⁵

If You’re Blocked: Enforcement and Penalties

Any covenant, deed restriction, or HOA rule that violates Section 714 is void from the start. You don’t need a court order to make it invalid, though you may need a lawsuit if the HOA or the city refuses to back off.

Against a non-public entity, including an HOA, a willful violation entitles the homeowner to actual damages plus a civil penalty of up to $1,000. The prevailing party in the enforcement action recovers reasonable attorney’s fees, which flips the usual financial calculus of fighting an HOA: if you win, the association pays your legal costs.¹

Against a public entity, the consequence is different. A city or county that fails to comply loses eligibility for state-sponsored solar grant and loan programs, and must certify compliance when applying for those funds.

Sunlight From a Neighbor’s Property

The Act does not give you an automatic right to sunlight crossing your neighbor’s land. California protects that access only through a solar easement, and solar easements are voluntary. Your neighbor is under no obligation to agree.

If both sides agree, Civil Code 801.5 requires the easement to be in writing and recorded, and to contain at least three elements: measurable dimensions of the easement described in angles or specific hours and dates; restrictions on vegetation, structures, and other objects that would block the sunlight; and the terms under which the easement may be revised or terminated.²

Without a recorded easement, a neighbor’s new addition or a growing tree can reduce your system’s output over time and you have no legal remedy under the Act.

Federal Tax Credit Note for 2026

The financial side of a California solar project changed at the end of 2025. The federal Residential Clean Energy Credit under 26 U.S.C. § 25D, which covered 30% of installation costs, was terminated for expenditures made after December 31, 2025.⁶ A $30,000 system installed in 2025 could claim a $9,000 federal credit; the same system installed in 2026 claims nothing federally. California state programs and utility rebates operate separately, so check with your utility and the California Energy Commission for current state-level incentives before signing a contract.
