Public Spaces, Parks, Streets & Sidewalks

Guide to Laws About Activities on Public Streets, Sidewalks, Parks, and other Public Spaces in San Francisco

1. Being on the sidewalk or street

Can the police tell me to get off the sidewalk?

As long as you are not blocking the flow of traffic, you have the right to be on a public sidewalk or to peacefully gather with others on public sidewalks, and police may not unreasonably restrict this right.1U.S. Constitution, 1st AmendmentCox v. Louisiana, 379 U.S. 536, 554 (1965); Frisby v. Schultz, 487 U.S. 474, 480 (1988)

Is it illegal to block the sidewalk?

In California, it is illegal to intentionally block the free movement of another person on a street, sidewalk or other public place.2Cal Penal Code 647c It is also a violation of the laws of San Francisco, with a penalty of $50-$500; additional violations can even result in jail time.3SF Police Code Sec 22, 23

What is loitering? Is it illegal?

Loitering means hanging around with no apparent purpose, and is not by itself illegal unless prohibited in specific places. However, in California, loitering or “lying in wait” with the intent to commit some crime is a crime in itself.5Cal Penal Code 647

It is also illegal to loiter in a public bathroom with the intent to have sex with someone, even if consensual6CA Penal Code Sec 647(d)

In the city of San Francisco, loitering is prohibited:

  • outside a nightclub during operating hours;7SF Police Code 121
  • outside an automatic public toilet;8SF Police Code 124.2

Do I have to carry ID at all times?

In California you are not required to show your ID (identification) or drivers license or to carry it with you (unless you are driving of course). Even if a police officer asks for your ID, you do not need to show it. The officer cannot arrest you simply for refusing.9California’s prior “stop and identify” law, Penal Code §647(e) was construed by a court in People v. Solomon (1973) to require “credible and reliable” identification that carries a “reasonable assurance” of its authenticity. Using this construction, the U.S. Supreme Court held the law to be void for vagueness in Kolender v. Lawson461 U.S. 352 (1983)

But it’s generally a good idea to comply with reasonable police officer requests, which can avoid further problems.

Also, if you are being cited for a misdemeanor offense, you ARE required to show ID at that time, otherwise you could be taken into custody.

2. Stuff on the street or sidewalk

Is it illegal to leave things in the street?

Yes, it is legal, as long as you follow these rules:

Signs are defined as any card, decoration, poster, campaign sign, or any object containing or bearing writing that is affixed, posted or fastened to a utility or light pole that is permanently attached to the street or sidewalk. In 2007, an ordinance was passed that restricts the posting of signs on city property.  The requirement was established to reduce litter and blight and minimize obstruction to ensure safety.

The public may post signs and information on some utility poles and lamp posts if the postings follow regulations outlined in Article 5.6 of the San Francisco Public Works Code:

Signs must:

  • not be larger than 8 1/2“ x 11”
  • conform to the shape of the pole
  • be attached with tape or other non-adhesive material such as twine, string or other non-metal banding material
  • be placed less than 12 feet from the ground
  • indicate date of posting and be removed by the poster within 10 days after an event or election date.

All signs continue to be prohibited on historic street light/lamp poles and on all traffic signal poles. The Department of Public Works may remove prohibited signs and administer penalties of $100 to $500. Call 3-1-1 to report illegally posted signs.
