Starting tonight, San Mateo police are rolling out nightly “Firework Suppression Units” to cruise neighborhoods and public spaces every evening through the Fourth of July, looking for anything that goes boom, crackle or fizz. Officers will confiscate fireworks of all kinds and issue citations when needed, city officials said. The ramped-up presence is aimed at cutting down on holiday-related fires, loud late-night blasts and avoidable injuries.

What the Patrols Will Do

The San Mateo Police Department laid out the plan on its Facebook page, explaining that the dedicated suppression units will be out every night between now and the Fourth of July. Officers will be on the lookout for any fireworks activity, with the authority to immediately confiscate fireworks and write citations when they find violations. That includes activity in residential neighborhoods, parks and other public spaces, with patrols designed to be proactive rather than just responding to complaints. The message from the city is simple: if it explodes, flies or sparkles inside San Mateo city limits, expect a visit.

The Law and Enforcement Powers

Under the San Mateo Municipal Code, it is illegal to sell, discharge, possess or use fireworks within city limits. The ordinance also gives the chief of police the authority to seize stocks of fireworks.

According to the San Mateo Police Department’s public materials, officers can issue administrative citations for violations, and more serious cases can be bumped up to state Health & Safety statutes. Depending on the type of device or the amount involved, those state laws can mean misdemeanor or even felony charges, a point the department underscores in its press materials outlining enforcement and reporting details.

Why the City Is Stepping Up Enforcement

Fire officials are blunt about the risk: dry weather, heavy demand on first responders and one stray spark are a bad combination, especially in a drought year. Local fire agencies have been urging residents to skip the backyard shows and keep it safe.

Peninsula cities have run similar suppression operations in recent years, at times hauling in large caches of illegal fireworks during holiday crackdowns. Those efforts form the backdrop for San Mateo’s current strategy, which leans on prevention rather than scrambling to respond once something has already gone wrong.

How to Report Illegal Fireworks

If you see fireworks being used inside San Mateo city limits, you are asked to contact San Mateo Police non-emergency dispatch at (650) 522-7700. You can also submit details through the city’s online reporting form and information hub for fireworks enforcement, which the department uses to track activity and target patrols.

Legal Implications

Anyone caught violating the city’s ban can face on-the-spot confiscation of fireworks and administrative citations under the municipal code. The city also has the authority to remove and dispose of illegal stockpiles.

The San Mateo Police Department notes that possession of certain dangerous fireworks or large quantities can trigger state Health & Safety charges with significantly stiffer penalties. Parents, the department cautions, may be held liable for damage or injuries caused when children get their hands on fireworks.
