Frequently Asked Questions

Do I need a permit to close my street for a block party in Petaluma?

Yes. Petaluma Municipal Code §13.32.040 requires a special event permit from the chief of police before closing any city street, and §13.32.030(C) defines a block party as exactly this kind of festive street closure for barbecues, picnics, music or games.

Does my block party have to be on a cul-de-sac?

The permit can require it. Section 13.32.090(K) states block parties must be located in a cul-de-sac to be approved, and the chief of police may also condition approval on written notice and approval from fifty percent of the residents on the affected street.

How far in advance do I need to apply?

File a verified application with the chief of police no less than thirty days and no more than ninety days before the event date, per §13.32.050(A). A late application may still be considered for good cause, such as a First Amendment event with an unavoidable short timeline.

What happens if I hold a block party without a permit?

It is unlawful under §13.32.170 to sponsor or conduct an event requiring a permit without one, and §13.32.190 makes any violation of Chapter 13.32 an infraction punishable under §1.04.060 of the code, with civil action also available to the city.
