How to File a Consumer Complaint in California

Learn the essential steps to file a consumer complaint in California, understand what types of issues can be reported, and find out what happens after you submit your complaint to protect your rights effectively.

Filing a consumer complaint in California is a straightforward way to address unfair business practices, deceptive acts, or concerns involving licensed professionals. The state’s Department of Consumer Affairs (DCA) plays a central role in handling complaints, protecting consumers, and enforcing laws that promote fair marketplace behavior.

This page provides an overview of the complaint process in California, including where to file complaints, what happens after a complaint is submitted, and useful links to more detailed guides.


What Types of Complaints Can You File?

Under California law, the Director of the Department of Consumer Affairs is responsible for receiving complaints about:

  • Unfair methods of competition or deceptive business acts in any trade or commerce
  • Goods or services that may endanger public health, safety, or welfare
  • Violations involving businesses and professions licensed by DCA agencies
  • Student concerns related to private postsecondary education and the Student Tuition Recovery Fund
  • Other matters consistent with consumer protection purposes

This broad scope means consumers can report everything from fraudulent sales practices to unsafe products or professional misconduct.


Where and How to File Your Complaint

To file a consumer complaint in California, follow these general steps:

1. Identify the appropriate agency or board:

The DCA consists of multiple boards and bureaus overseeing specific industries and professions (e.g., Contractors State License Board, Medical Board, Bureau for Private Postsecondary Education). Some complaints are best directed to a specific board, while others can be filed directly with the DCA.

2. Gather relevant information:

Include details such as business or professional name, dates, descriptions of the problem, and any supporting documents (contracts, receipts, correspondence).

3. Submit your complaint:

    • Use the DCA's online complaint portal for many types of complaints.
    • For certain boards or bureaus, filing instructions and forms are available on their respective websites linked through the DCA.
    • Complaints can also sometimes be submitted by mail or phone—check the relevant board’s contact information.

4. Keep a copy:

Retain copies of your complaint and all supporting materials for your records.


What Happens After You File a Complaint?

Once the Director of Consumer Affairs receives a complaint, several actions may follow:

Notification to the alleged party:

The person or business complained against may be notified of the complaint and asked to respond or provide relief.

Referral to the proper agency:

The complaint may be forwarded to a local, state, or federal agency with the best authority to act.

Investigation:

If there is a probable violation or a pattern of complaints, the DCA or the relevant board may investigate further, potentially involving the Division of Investigation or law enforcement.

Action and resolution:

Depending on the findings, the agency may seek corrective action, discipline, or legal enforcement. The consumer will be informed of any actions taken or other options available.

Prioritization:

Some complaints, such as those alleging serious harm to minors, receive highest priority under complaint guidelines.
