Can a California HOA ban rooftop solar?

Usually, no. California law makes deed restrictions and HOA governing-document provisions void when they effectively prohibit or restrict a solar energy system. An HOA may still apply reasonable restrictions, and the system must meet applicable safety and permitting requirements. When HOA approval is otherwise required, section 714 sets rules for processing the application. Extra rules can apply when the proposed system would use a roof or other area shared by multiple homeowners.

This page is for California homeowners in a common interest development who are considering a household rooftop photovoltaic system. It does not decide who owns or controls a particular roof, whether a specific design is structurally safe, or whether a permit or utility approval will be issued.

What the statewide rule protects

California Civil Code section 714 says a covenant, restriction, condition, or governing-document provision that effectively prohibits or restricts the installation or use of a solar energy system is void and unenforceable. The same section allows reasonable restrictions that do not significantly increase the system's cost or significantly reduce its efficiency or specified performance, or that allow an alternative system of comparable cost, efficiency, and energy-conservation benefits.

For photovoltaic systems, section 714 uses $1,000 in added cost and a 10 percent decrease in system efficiency as its statutory benchmarks. Ask the installer to put the cost and expected performance of the proposed system—and of any HOA-requested alternative—in writing so the two designs can be compared.

A solar installation must still comply with applicable state and local health and safety requirements, permitting rules, electrical standards, and utility safety and reliability rules. HOA approval does not replace those requirements.

How long the HOA has to respond

When HOA approval is required, the application must be handled like an architectural-modification request and must not be willfully avoided or delayed. The approval or denial must be in writing. If the association does not deny the application in writing within 45 days after receiving it, section 714 says the application is deemed approved unless the delay resulted from a reasonable request for additional information.

Keep proof of the date the HOA received the application, any reasonable request for additional information, and the date any additional information was provided. Do not assume that deemed HOA approval is a building permit or permission to skip electrical, structural, fire, utility, or contractor requirements.

What an HOA may still require

Civil Code section 714.1 allows reasonable provisions that limit common-area installations to systems the association approves; require association approval before one owner installs a system in another owner's separate interest; provide for maintenance, repair, or replacement of roofs or other building components; and require installers to indemnify or reimburse the association or its members for installation-, maintenance-, or use-related loss or damage. It also says an association may not establish a general policy prohibiting a household rooftop solar system on the roof of the building where the owner lives, or on an adjacent garage or carport assigned for that owner's exclusive use. For those installations, it also may not require approval by a vote of members who own separate interests, including the vote specified by section 4600. An association action that violates either prohibition is void and unenforceable.

If the proposed system would be installed on a multifamily common-area roof shared by more than one homeowner, Civil Code section 4746 requires the association to require the applicant to notify each owner of a unit in the building. It must also require the owner and each successive owner to maintain homeowner liability coverage at all times, provide the insurance certificate within 14 days after approval, and provide it annually thereafter. The association may impose additional reasonable provisions requiring a solar site survey prepared by a licensed contractor or the contractor's registered salesperson knowledgeable about solar installation. The survey must determine usable solar roof area and an equitable allocation of that area among all owners sharing the same roof, garage, or carport. The survey or costs of determining usable space do not count as system cost under section 714. The association may also require the owner and each successive owner to bear the specified costs of damage, system maintenance, repair and replacement until removal, and restoration after removal, and to disclose the system and related responsibilities to prospective buyers.

A practical application checklist

Confirm whether the proposed roof is your separate interest, exclusive-use common area, or a multifamily common-area roof shared with other owners.
Ask whether HOA approval is required and request any current solar or architectural-application requirements in writing.
Submit the proposed layout, equipment, system cost, expected performance, contractor information, and any requested structural or insurance documents.
Keep the complete submission, attachments, delivery confirmation, and every response.
If the HOA proposes another design, ask for its added cost, expected efficiency or performance, and energy-conservation benefits in writing and compare the two systems under section 714's standards.
If the HOA denies the request, ask it to identify the exact governing provision, explain the factual reason, and provide the written decision.
Continue to follow local permitting, electrical, fire, structural, contractor-licensing, and utility requirements.

If there is a dispute

Start with the documents: the application, proof of receipt, the written decision or request for more information, the governing provision, and the installer's cost-and-performance comparison. Civil Code section 714 says a nonpublic entity that willfully violates the section is liable for actual damages caused by the violation and a civil penalty of up to $1,000. It separately says the prevailing party in an action to enforce compliance shall be awarded reasonable attorney's fees. Whether a violation was willful or a restriction was reasonable depends on the facts. Consider advice from a California attorney familiar with common interest developments before relying on a deemed approval, starting work over an objection, or pursuing a claim.
