Know The Law
The California Penal Code includes multiple sections that penalize types of criminal trespass. Most of these provisions
are located in Penal Code section 602. Additionally, many jurisdictions have local trespassing ordinances.
This is an example of a basic
"No Trespassing" sign.
"No Trespassing" signs are required to enforce certain violations. The sign and font should be large enough that it is legible from the nearest public street/sidewalk. The signs should reference the proper Penal Code and/or local ordinance sections that the business would like enforced. At a minimum, signs should be placed at the entrance(s) to the property. Some statutes contain specific requirements for sign size, lettering size, and sign placement. Property owner or manager should review the applicable statutes to ensure that their signs meet the applicable requirements.

Beginning January 1, 2024, Penal Code section 602(o) authorizes a single request for a peace officer's assistance, made in a notarized writing on a form provided by the law enforcement agency, to cover a period of up to 12 months, unless the local ordinance identifies a shorter period of time.
