All Fireworks Are Illegal In San Mateo. You light it, we write it.  

The San Mateo Municipal Code prohibits the discharge, use, and sale of fireworks within the City of San Mateo. Fireworks of all types, including those classified by the State Fire Marshall as “safe and sane,” are prohibited in San Mateo.

On April 19, 2021, San Mateo City Council adopted Chapter 10.20 “Fireworks” to the San Mateo Municipal Code, which authorizes the San Mateo Police Department to seize fireworks and to issue citations to those individuals who violate the code, but whose violations do not meet the criteria for misdemeanor or felony state law violations.  On May 19, 2021, the code became effective.

A fine of $100 will be imposed for the first violation within a year. A fine of $200 will be imposed for the second violation within a year. After two violations within a year, the fine will increase to $500 for every violation within that same year.  

How to Report Fireworks Violations

Contact SMPD

To report violations, please use our non-emergency Dispatch number at (650) 522-7700.  Do not call 9-1-1 unless an actual emergency is involved.  SMPD will be conducting high visibility patrols and enforcement throughout San Mateo in addition to responding to complaints.  

Fireworks Violation Form

Additionally, the San Mateo Police Department launched a new system to curtail the use of fireworks in San Mateo.  Residents who witness a fireworks violation are encouraged to report their observations using SMPD’s Fireworks Violation Form.  Although reporting through the form WILL NOT notify dispatch, it will be forwarded to SMPD for a follow-up investigation.  This reporting system helps the police department devote more resources to problem areas and allows our community members to report violations anonymously.
