The short answer
- California's Solar Rights Act lets an HOA set reasonable rules for solar, but not ban it.
- A rule is unreasonable if it adds more than $1,000 to the cost of a solar electric system or cuts its efficiency by more than 10% (Civil Code §714).
- An application not denied in writing within 45 days is approved.
- An HOA can't require a membership vote for a system on your own roof or assigned garage or carport (§714.1).
What an HOA may do
- Require you to apply and get approval first.
- Set placement or appearance rules within the $1,000 / 10% limits.
- Limit systems on common areas to ones it approves.
- Provide for roof maintenance and replacement, and require installers to cover damage to the association (§714.1).
Shared roofs (condos and townhomes)
When your system goes on a shared roof, you must carry liability coverage, pay for damage to common areas and the system's upkeep, restore the roof when the system comes off, and tell buyers about it. The HOA may require a survey to divide roof space fairly (Civil Code §4746). For condo options, see solar for condos and renters.
How to apply
- Ask for the HOA's architectural rules and application form.
- Submit the installer's layout, equipment and a cover letter citing Civil Code §714 and the 45-day deadline.
- If the HOA asks for changes, ask the installer to price them: anything over $1,000 extra, or over 10% less production, is unreasonable under the law.
- Keep dated copies of everything.
