Timeline: Sunrun aims to resolve standard billing or technical inquiries within 5 to 7 business days. Hardware failures, roof leak investigations, or grid interconnection delays can take significantly longer due to third-party utility involvement.
Level 2: Formal Corporate Escalation (Notice of Dispute)
-
Who to contact: If standard support is unsuccessful (especially regarding roof damage, severe system underperformance, or deceptive sales tactics), Sunrun’s Terms of Service dictate you must send a formal written “Notice of Dispute” detailing the issue and your specific request for relief via certified mail to their corporate legal headquarters: Sunrun Inc., Attn: Legal Department, 225 Bush Street, Suite 1400, San Francisco, CA 94104.

-
Timeline: Once received, Sunrun’s legal and executive resolution teams have a mandatory informal resolution window (typically 30 days) to investigate and attempt an amicable settlement before you are legally permitted to proceed to arbitration or court.
Level 3: Regulatory Authority (Government Ombudsman)
-
Authority: Your State Contractor Licensing Board and your State Attorney General.
-
Portal/Contact: Because Sunrun physically alters your home, they must maintain a contractor’s license in your state. Filing a complaint against their license is highly effective for installation damages or system failures.
-
California Example: File a complaint with the Contractors State License Board (CSLB) at cslb.ca.gov.
-
Other States: Search for your specific state’s “Contractor Licensing Board” or file a consumer complaint directly with your State Attorney General’s office.
-
Timeline: You can file a regulatory complaint at any time after attempting to resolve the issue directly. State boards will assign an investigator who can compel Sunrun to fix installation defects or face fines/license suspension.
Level 4: Legal Action (Final Step)
- Pre-Litigation: Before pursuing legal action, carefully review your specific Sunrun Solar Agreement (PPA or Lease). Sunrun strictly enforces a Mandatory Binding Arbitration clause and a Class Action Waiver for all U.S. consumer disputes.
- Court/Arbitration: If the informal resolution period (Level 2) fails, Sunrun’s contract generally allows you to file a lawsuit in Small Claims Court for individual claims below your state’s limit (e.g., $12,500 in California), bypassing arbitration entirely. If the dispute exceeds small claims limits, you are required to initiate Binding Arbitration through JAMS or the American Arbitration Association (AAA) as designated in your contract.
