Solar Energy in San Ramon, CA

If you live in San Ramon or are thinking about moving there, solar energy are one of those things you probably won't think about until they affect you directly. San Ramon has 3 specific rules on the books covering different aspects of solar energy, and some of them might surprise you.

Expedited Solar Permitting

San Ramon's building and safety services division must use a nondiscretionary, administrative review to approve small residential rooftop solar systems up to 10 kW AC or 30 kW thermal on single- and two-family homes. Complete applications meeting the city's standard checklist get one building permit and one inspection; a health-or-safety finding can trigger a minor use permit instead.

Key details: Max system size: 10 kW AC or 30 kW thermal. Eligible dwellings: Single- or two-family homes. Inspections required: One, for eligible systems. Appeal body: City planning commission. State authority: AB 2188 / Gov't Code § 65850.5.

There is no separate fine schedule in this chapter: installing or modifying a system without the required building permit is enforced as unpermitted construction under the city's building code, which can mean stop-work orders and permit-cost penalties until the work is legalized. If the chief building official requires a minor use permit over a health-or-safety impact and it is denied, the applicant's recourse is an appeal to the city planning commission, not continued construction.

Panel Permits

San Ramon requires rooftop solar applicants to use a standard plan and checklist that the building and safety services division adopts and posts on the city website before a permit can issue. Applications and every supporting document can be filed electronically by email, fax or the internet under Municipal Code § C8-5.

Key details: Application format: Electronic: email, fax or internet. Standard reference: California Solar Permitting Guidebook. Reviewing division: Building and Safety Services. Incomplete filing: Written correction notice issued.

Filing an incomplete application does not draw a fine, it draws a written correction notice under §§ C8-5 and C8-6 listing every deficiency so the applicant can resubmit. Installing a system without ever obtaining the permit is treated as unpermitted construction under the building code, exposing the homeowner to stop-work orders and after-the-fact permitting requirements rather than a fixed penalty amount.

HOA Restrictions

California Civil Code Section 714 (Solar Rights Act) prohibits San Ramon HOAs from banning solar panels. HOAs and CC&Rs can impose only 'reasonable restrictions': those that do not significantly increase system cost (over $1,000 for PV) or decrease efficiency by more than 10%. HOA approval must be granted within 45 days or it is deemed approved. Civil Code 4600 and 4745 reinforce homeowner solar rights. San Ramon's many HOA communities (Gale Ranch, Windemere, Canyon Lakes) must comply.

Key details: Solar Ban: Civil Code 714 prohibits HOA solar bans (Solar Rights Act). Efficiency Threshold: Restrictions must not add $1,000+ cost or reduce efficiency 10%+. Approval Timeline: HOA must approve/deny within 45 days (auto-approved if silent). Towing: Civil Code 4746 extends to condo/townhome common roofs. Attorney Fees: Prevailing homeowner can recover attorneys' fees.

San Ramon is more permissive than most cities when it comes to hoa restrictions. That said, there are still limits.

The Bottom Line

San Ramon's solar energy rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming San Ramon is broadly strict or permissive.

These rules come from San Ramon's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
