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:

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.
