HOA and Solar in California: What Your Association Can — and Can’t — Require

Last verified: September 2026. This article explains state law in plain language. It is general information, not legal advice — for a dispute with your association, consult a California HOA attorney. If you live in an HOA community in Los Angeles or Orange County and you're considering solar, you've probably heard some version of "the HOA won't allow it." In California, that's almost never legally true. What an HOA can do is slow you down or shape the design — and even that power is tightly limited by state law. This guide covers what the law actually says, what a board can legitimately ask for, and how to submit an application that's hard to deny.

The short version

• Your HOA cannot prohibit solar. California's Solar Rights Act (Civil Code §714) makes any covenant, restriction, or condition that effectively bans a solar energy system void and unenforceable.
• Restrictions must be "reasonable." A requirement is unreasonable — and therefore unenforceable — if it increases the system's cost by more than $1,000 or decreases its efficiency by more than 10% compared to your proposed design (thresholds set by AB 2188, 2014). These are statutory limits on the HOA, not installation prices.
• 45 days, then deemed approved. If your application is complete and the association doesn't deny it in writing within 45 days, it is deemed approved — unless the delay is caused by something reasonably outside the board's control.
• No membership vote. An association can't put your rooftop solar to a vote of the members, and approval can't be willfully avoided or delayed.
• Condos and shared roofs are covered too. Since AB 634 (2017), owners in common-interest developments can generally install on the roof of their own unit, garage, or carport, subject to the process in Civil Code §4746 — which can include a solar site survey and fair allocation of usable roof area among units sharing the roof.

What a board can legitimately require

The law leaves room for reasonable, health-and-safety-based rules. Expect — and plan for — requirements like:

• An architectural application processed the same way, and on the same timeline, as any other improvement request. The association must use the same approval process it applies to other architectural changes.
• Reasonable placement and appearance conditions, as long as they stay under the $1,000 / 10% thresholds. Example: asking for panels to sit flush and parallel with the roof slope is usually fine; demanding they move to a shaded north face that guts production usually isn't.
• For shared roofs (§4746): proof of a solar site survey, an agreement on maintenance and repair responsibility for roof damage attributable to the system, and homeowner liability coverage naming the association — the statute caps what can be demanded here, and a qualified installer will have handled these documents before.
• Licensed, permitted work. Every jurisdiction in LA and Orange County requires a permit for solar regardless of the HOA; the association can ask for evidence the work is permitted and performed by a licensed contractor.

What a board cannot do

• Ban solar outright, in the CC&Rs or by practice
• Impose aesthetic conditions that add more than $1,000 in cost or cut production more than 10% versus your proposed system
• Sit on a complete application past 45 days and treat silence as a denial
• Require a vote of the membership before approval
• Charge an application fee or process for solar that's harsher than what it applies to comparable architectural requests

An association that willfully violates §714 can be liable for a civil penalty and the applicant's attorney's fees — which is worth mentioning, politely, if a board claims solar is simply "not allowed."

How to submit an application that gets approved

1. Get the design first. Submit a real plan — panel layout, mounting detail, equipment spec sheets — not a concept. Vague applications invite "incomplete" responses that restart the clock.
2. Use the association's own form and process. Ask management for the architectural request procedure in writing, and note the date you submit.
3. Pre-answer the aesthetic questions. Flush-mounted layout drawings, equipment placement, and conduit routing shown up front remove the board's most common objections before they're raised.
4. Put the statute in the packet. A cover page citing Civil Code §714 and §4746, the 45-day deemed-approval rule, and the $1,000/10% reasonableness thresholds tends to keep review focused and on schedule.
5. Calendar day 45. If the deadline passes without a written denial, follow up in writing referencing the deemed-approval provision.

A good installer does steps 1–4 for you as part of the job. When we design a system for an HOA property, the architectural packet — layout drawings, spec sheets, the §714/§4746 cover memo, and the site-survey documents for shared roofs — is part of the scope, and we build the 45-day window into the project timeline so HOA review doesn't stall permitting or installation.

Frequently asked questions

Can my HOA make me move panels to a less visible roof face?

Only if doing so keeps the added cost under $1,000 and the production loss under 10% versus your proposed design. If relocating panels to satisfy aesthetics breaks either threshold, the condition is unreasonable under §714.

Does the 45-day clock start when I first email the board?

It runs from a complete application under the association's process. That's why submitting a full design package on the association's own form matters — it removes the argument that the application was incomplete.

I'm in a condo with a shared roof. Is it different?

Yes — §4746 adds steps (site survey, usable-area allocation among units sharing the roof, maintenance and insurance terms) but the bottom line holds: the association can shape the installation, not block it.

What about batteries and EV chargers?

Battery systems installed with solar generally ride under the same application. EV charging stations have their own protective statute (Civil Code §4745) with a similar structure: reasonable restrictions only, and an application processed like any other architectural request.

Do HOA rules affect incentives?

No — eligibility for federal or state incentives is a separate question that depends on program rules and current law, not on HOA approval. Incentives may be available subject to eligibility; Home Upgrade Specialist is not a tax advisor, and customers should consult their tax professional.
