What Are Criminal Trespassing Charges in San Jose, CA?
October 14, 2026 | Nafiz M. Ahmed
Criminal trespassing means being somewhere you don’t have the legal right to be or staying after that right ends. However, not every unauthorized entry amounts to a crime. Whether someone can be charged depends on the circumstances and the specific conduct involved.
California Penal Code § 602 identifies numerous acts that can constitute trespassing, generally involving willfully entering, remaining on, occupying, or interfering with someone else’s property under prohibited circumstances.
Common Examples of Criminal Trespassing
Trespassing charges can arise from a wide range of situations, including:
- Entering and occupying property without consent
- Refusing to leave certain private property after being told to leave
- Entering posted property without permission in circumstances covered by the law
- Entering property intending to interfere with or damage a lawful business
These charges can stem from disputes with landlords or roommates, refusing to leave a store or bar, returning to an ex-partner’s home, protests on business property, or encampments on private land.
Because California law covers many different types of trespassing, prosecutors must prove the elements of the specific offense charged. Simply showing that someone entered another person’s property is not always enough for a conviction.
Is Entering Someone Else’s Property Always Trespassing?
Not necessarily. Simply stepping onto property owned by another person does not automatically establish criminal trespass. The specific circumstances matter, like whether you had permission, whether the property was open to the public, if you were told to leave, if you left after being told to leave, what signs were posted (if any), what you did after entering, and whether you intended to interfere with the property or a business.
When building your defense, make sure you specifically know what you’re charged with so you can start considering your defense.
What Are the Penalties for Trespassing in California?
Many violations of Penal Code § 602 are misdemeanors, but the penalties depend on the exact subsection and the circumstances of the offense. Certain forms of trespass could be infractions, while others can carry enhanced penalties for repeat conduct or for refusing to leave after being directed to.
Ordinary residential trespass under § 602.5(a) is a misdemeanor punishable by up to six months in county jail, a fine of up to $1,000, or both. Aggravated residential trespass under § 602.5(b) carries up to one year in county jail, a fine of up to $1,000, or both.
Possible Legal Defenses to Criminal Trespass
If you’re facing a trespassing charge in California, several legal defenses may be available depending on the facts of your case. The right strategy depends on the circumstances of the alleged incident, your intent, evidence, and any communication with the property owner.
Below are examples of common defenses to criminal trespassing:
- Lack of intent: If your entry or presence was accidental, that may undermine the prosecution’s ability to prove a willful act. A reasonable mistake about property boundaries or permission may also be relevant, depending on the specific trespass subsection charged.
- Consent or permission: Entering or remaining on property with the owner’s or authorized occupant’s permission is generally not trespassing. If you were allowed to be on the property, either your presence was communicated clearly or implied through behavior; consent is a valid defense.
- Lack of notice or warning: Some trespass charges require specific notice, warnings, fencing, or posted signs. If those requirements were not satisfied, the prosecution may be unable to prove an element of the particular trespass offense charged.
- Duress, necessity, or emergency: If you entered onto the property to avoid harm to yourself or others during an emergency, the legal doctrines of duress or necessity may serve as a defense. For instance, running onto private property to escape immediate danger or help someone in distress may not amount to criminal conduct.
If you have been charged with trespassing, review your situation with an experienced criminal defense lawyer.
