Trespassing Lawyers in San Diego (PC 602)

Trespassing charges under PC 602 can leave you with a criminal record that follows you for years. Our San Diego defense lawyers fight for dismissals and reductions. Call 24/7.

A trespassing charge in San Diego changes everything overnight. What might seem like a minor misunderstanding, being in the wrong place at the wrong time, suddenly becomes a criminal case with your name on it.

Most people facing trespass charges never imagined being in this situation. A dispute with a landlord that spiraled out of control. A misunderstanding about property boundaries. Returning to a place you thought you still had permission to be. An encounter with law enforcement at a protest or public gathering. The circumstances that lead to PC 602 charges are rarely as simple as the prosecution makes them sound.

Charges are accusations, not convictions. The prosecution still has to prove every element beyond a reasonable doubt, and that’s a higher bar than most people realize, especially in trespassing cases where intent, consent, and notice are often genuinely disputed.

Being charged with a misdemeanor might not sound serious compared to a felony, but make no mistake: a trespassing conviction creates a criminal record. That record shows up on background checks for jobs, housing applications, professional licensing boards, and more. For many of our clients, the collateral consequences of a trespass conviction matter far more than the fine or probation the court imposes.

At David P. Shapiro Criminal Defense Attorneys, we’ve defended clients charged with trespassing throughout San Diego County, from downtown to Chula Vista, El Cajon, and Vista. As experienced San Diego property crimes defense lawyers, we know how these cases work in San Diego courts, and we know how to challenge them.

Time matters. Early action creates options that disappear later. The sooner we get involved, the more we can do.

What Is Trespassing Under California Law?

So what exactly is trespassing under California law? Well, Penal Code Section 602 is one of the longest statutes in the entire Penal Code, containing over 30 subsections, each defining a different type of prohibited conduct.¹ It is not one single offense. It is a collection of related acts, all falling under the umbrella of entering or remaining on someone else’s property without authorization.

The core concept across all subsections is this: you entered, occupied, or refused to leave property that belongs to or is lawfully occupied by another person, and you did so willfully, meaning intentionally.

Now here’s the thing. “Willfully” is a critical word. It means the prosecution has to prove you intended to be on that property. If you wandered onto someone’s land by accident, didn’t realize you’d crossed a property line, or genuinely believed you had permission to be there, the prosecution has a problem proving their case.

Let’s walk through the subsections that come up most often in San Diego courtrooms.

The Most Commonly Charged Subsections

PC 602, subdivision (m): Entering and occupying property without consent. This is the classic trespass scenario. You entered someone else’s property or structure and occupied it without the consent of the owner, their agent, or the person in lawful possession.²

PC 602, subdivision (o): Refusing to leave after being asked. You were on someone else’s property, the property was not open to the general public, and an authorized person (the owner, their agent, or a peace officer acting at their request) asked you to leave. You refused or failed to do so.³

PC 602, subdivision (n): Driving on private property without consent. You drove a vehicle onto someone else’s real property when signs were posted forbidding that use.⁴

PC 602, subdivision (k): Entering cultivated or fenced land. You entered land under cultivation or enclosed by a fence, or entered unenclosed land where “no trespassing” signs were posted at intervals of not less than three to the mile along the exterior boundaries.⁵

Each of these subsections has slightly different elements, which means each one presents different defense opportunities. That distinction matters.

What Must the Prosecution Prove?

The specific elements depend on which subsection you’re charged under. Let’s break down the two most commonly charged versions.

Entering and Occupying Property (PC 602, subd. (m))

To convict you under this subsection, the prosecutor must prove ALL of the following beyond a reasonable doubt:⁶

1. You entered property belonging to or lawfully occupied by someone else. The prosecution has to establish who owns or lawfully possesses the property and that you entered it.

2. You occupied that property. “Occupied” means more than just walking through. It implies some degree of remaining or settling in, however briefly.

3. You did not have the consent of the owner, the owner’s agent, or the person in lawful possession. This is often where cases fall apart. Consent can be express or implied, and the prosecution must prove its absence.

4. You acted willfully. You intended to enter and occupy the property. Accidental or unknowing entry is not a crime.

Refusing to Leave (PC 602, subd. (o))

To convict you under this subsection, the prosecutor must prove ALL of the following beyond a reasonable doubt:⁷

1. You were on property belonging to or lawfully occupied by someone else.

2. The property was not open to the general public.

3. You were asked to leave by the owner, the owner’s agent, the person in lawful possession, or a peace officer acting at the request of any of those persons. The request must come from an authorized person. A fellow tenant or random bystander doesn’t count.

4. You refused or failed to leave.

5. You acted willfully.

Every element is a question mark for the prosecution and an opportunity for the defense. If they can’t prove any single one of these beyond a reasonable doubt, you cannot be convicted.

Trespass vs. Burglary: Understanding the Difference

This is one of the most important distinctions in California criminal law, and it’s one our clients frequently need to understand.

What does the difference between trespass and burglary actually look like? Well, it comes down to one word: intent.

Trespass under PC 602 means entering or remaining on someone’s property without authorization. That’s it. No additional criminal intent required beyond the willful act of being there.⁸

Burglary under Penal Code Section 459 means entering a structure with the intent to commit theft or any felony inside.⁹ The prosecution doesn’t have to prove you actually stole anything or committed any other crime. They just have to prove you had that intent when you entered.

Why does this matter so much? Because the consequences are dramatically different:

Charge	Classification	Potential Sentence	Strike Offense
Trespass (PC 602)	Misdemeanor	Up to 6 months jail	No
Second-Degree Burglary (PC 459)	Wobbler	Up to 3 years state prison (felony)	No
First-Degree Residential Burglary (PC 459)	Felony	2, 4, or 6 years state prison	Yes

See that enormous gap? First-degree burglary is a strike offense under California’s Three Strikes Law. Trespass is a misdemeanor with a maximum of six months.

This is why trespass is frequently the “landing zone” in plea negotiations for more serious charges. If you were originally charged with burglary, a reduction to trespass can be the difference between a strike on your record and a misdemeanor that may eventually be expunged. If you’re facing burglary charges, this distinction could be the most important thing you read today.

Related Trespass Offenses

California law includes several trespass-related statutes beyond PC 602, and the prosecution’s charging decision can significantly affect what you’re facing.

Aggravated Trespass (PC 601)

Aggravated trespass is a wobbler, meaning it can be charged as either a misdemeanor or a felony.¹⁰ What separates it from simple trespass is the threat element. The prosecution must prove:

1. You made a credible threat to cause serious bodily injury to someone

2. Within 30 days of making that threat, you unlawfully entered that person’s residence, property, or workplace

3. You entered with the intent to carry out the threat

As a misdemeanor, aggravated trespass carries up to one year in county jail and a fine up to $2,000. As a felony, it carries 16 months, two, or three years in state prison and a fine up to $10,000.¹¹

Unauthorized Entry of a Dwelling (PC 602.5)

This is a misdemeanor charge for entering an inhabited dwelling without consent.¹² It’s more serious than standard trespass but less serious than burglary. A first offense carries up to six months in county jail. If someone was present in the dwelling at the time of entry, the maximum increases to one year.

Trespass on Posted Cultivated or Fenced Land (PC 602.8)

A first offense is an infraction, not a criminal charge, with a maximum fine of $75.¹³ A second offense raises the fine to $250. A third or subsequent offense becomes a misdemeanor. This distinction matters because an infraction does not create a criminal record.

Penalties and Consequences

Direct Penalties

For most subsections of PC 602, the direct penalties are relatively modest by criminal law standards:

Offense	Classification	Maximum Jail	Maximum Fine	Probation
Standard Trespass (PC 602)	Misdemeanor	6 months county jail	$1,000	Up to 3 years informal
Aggravated Trespass (PC 601, misd.)	Misdemeanor	1 year county jail	$2,000	Up to 3 years
Aggravated Trespass (PC 601, felony)	Felony	3 years state prison	$10,000	Formal probation
Posted Land, 1st offense (PC 602.8)	Infraction	None	$75	N/A
Posted Land, 2nd offense (PC 602.8)	Infraction	None	$250	N/A
Posted Land, 3rd+ offense (PC 602.8)	Misdemeanor	6 months	$1,000	Up to 3 years
Unauthorized Entry of Dwelling (PC 602.5)	Misdemeanor	6 months (1 year if occupied)	$1,000	Up to 3 years

In practice, first-time trespass offenders in San Diego County often receive probation and a fine rather than jail time. But the real damage isn’t the sentence. It’s what comes after.

Collateral Consequences

For all intents and purposes, the collateral consequences of a trespass conviction can be far more damaging than the court-imposed penalties. Here’s what many people don’t realize until it’s too late.

Employment Impact

A misdemeanor trespass conviction creates a criminal record that appears on standard background checks. Employers in California can ask about criminal convictions after a conditional job offer is made, and a trespass conviction can disqualify you from positions in security, property management, real estate, education, healthcare, government, and many other fields. For people in competitive job markets, this is not a minor issue.

Housing Applications

Landlords routinely run criminal background checks on prospective tenants. A trespass conviction, particularly one involving unauthorized entry of a dwelling or refusal to leave, can make it significantly harder to secure housing. The irony is not lost on us.

Professional Licensing

Trespass may be classified as a crime involving moral turpitude depending on the specific circumstances, which can trigger disciplinary proceedings before licensing boards. If you hold a professional license in fields like law, medicine, nursing, real estate, teaching, or financial services, a conviction could put that license at risk.

Immigration Consequences

Standard misdemeanor trespass is generally not considered an aggravated felony under federal immigration law. However, the moral turpitude analysis can be complicated depending on the specific subsection charged and the underlying facts. If you are not a U.S. citizen, even a misdemeanor conviction can have immigration consequences that must be evaluated carefully by an attorney who understands both criminal and immigration law.

Firearm Rights

A misdemeanor trespass conviction does not trigger a firearm prohibition. However, a felony conviction for aggravated trespass under PC 601 results in a lifetime ban on possessing firearms under both California and federal law.

Record and Expungement

A trespass conviction is eligible for expungement under Penal Code Section 1203.4 after you complete probation.¹⁴ Expungement allows you to withdraw your guilty plea and have the case dismissed, which can help with employment and housing applications. It does not erase the arrest record entirely, but it changes how the conviction appears.

Defense Strategies for Trespassing Charges

Now let’s talk about what can actually be done about these charges. Trespassing cases present more defense opportunities than most people realize, because the prosecution has to prove specific elements that are often genuinely disputed.

Lack of Willfulness

The prosecution must prove you acted willfully, meaning intentionally. What does that look like in practice? Well, imagine a situation where you’re hiking and you cross onto private property without realizing it. Or you’re in a large commercial complex and you wander into a restricted area that wasn’t clearly marked. Or you’re visiting a property where you used to live and genuinely didn’t know your access had been revoked.

In all of these situations, you didn’t intend to trespass. And without that willful mental state, the prosecution cannot convict you. This defense is especially effective in cases involving unmarked rural land, ambiguous property lines, or properties adjacent to public spaces.

Consent or Right to Enter

If you had express or implied consent to be on the property, there’s no trespass. We can, and will, challenge the prosecution’s claim that consent was absent if the facts support a position to do so. Consent defenses arise in many contexts:

• The property was open to the public or appeared to be
• You had a prior relationship with the owner as a tenant, guest, or family member
• Someone you reasonably believed had authority gave you permission
• You were on the property for a legitimate business purpose, such as a delivery or service call

No Request to Leave or Inadequate Request

For charges under PC 602, subdivision (o), the prosecution must prove you were asked to leave by an authorized person and refused. This element fails more often than you’d think. Defenses include:

• No request was actually made
• The request was vague or ambiguous
• The person making the request had no authority (a fellow tenant rather than the owner or their agent)
• You didn’t hear or understand the request due to noise, distance, or language barriers

Insufficient Notice or Inadequate Posting

For subsections that require posted signs, the statute specifies exact requirements: signs must be posted at intervals of not less than three per mile along exterior boundaries and at all roads and trails entering the land.¹⁵ Faded signs, improperly spaced signs, or signs obscured by vegetation may be legally insufficient. We scrutinize these details because they matter.

Constitutional Protections

In some cases, you may have had a legal right to be where you were. California recognizes broader speech protections than the federal Constitution in certain contexts. The California Supreme Court held in Pruneyard Shopping Center v. Robins that individuals may exercise free speech rights in certain quasi-public spaces like shopping centers.¹⁶ Additionally, union organizers may have limited access rights under the Labor Code, and individuals engaged in peaceful protest on public property have First Amendment protections.

Tenant Rights Defense

This comes up more often than people expect. If you’ve been living on a property, you may have established legal tenancy, even without a formal lease. A landlord cannot use criminal trespass law to evict someone who has tenant rights. The proper remedy is a civil eviction proceeding, not a criminal prosecution. We investigate whether our clients have established tenancy rights that make the trespass charge legally inappropriate.

Necessity or Emergency

You entered the property out of genuine necessity: to escape imminent danger, to render emergency aid to someone inside, or to retrieve a child or animal in a dangerous situation. This is an affirmative defense, and it requires showing that the emergency justified the entry.

Mistaken Identity or Insufficient Evidence

The prosecution must prove beyond a reasonable doubt that you were the person who trespassed. In cases involving unclear surveillance footage, high-traffic areas, or no direct eyewitness identification, the evidence may simply be insufficient to convict.
