A criminal trespass charge under New Jersey’s 2C:18-3a is either a disorderly persons offense carrying up to six months in county jail and a $1,000 fine, or a fourth-degree indictable crime carrying up to 18 months in state prison and a $10,000 fine. Which one you face depends entirely on the type of property involved. On top of the fine, every conviction triggers mandatory court assessments that judges cannot waive, and the conviction itself stays on your record until you obtain an expungement.
How the Charge Is Graded
Most unlicensed entry under 2C:18-3a is charged as a disorderly persons offense, roughly the New Jersey equivalent of a misdemeanor. The grading jumps to a fourth-degree crime, which is an indictable offense, when the property falls into one of the categories the Legislature singled out as more sensitive.1Justia. New Jersey Code 2C:18-3 – Unlicensed Entry of Structures; Defiant Trespasser; Peering Into Dwelling Places; Defenses
Those elevated categories are:
- Dwellings — any place a person regularly uses for sleeping, which can include houses, apartments, overnight accommodations, and even non-traditional spaces adapted for sleeping
- Schools and school property
- Research facilities
- Power generation facilities
- Water treatment and public water facilities
- Waste treatment and public sewage facilities
- Nuclear electric generating plants
- Facilities storing or handling hazardous chemicals
- Utility company property
- Airport sterile or operational areas
The dwelling category is the one that most often catches people off guard, because it does not require a lease, a locked door, or any particular showing of harm. If someone regularly sleeps there and you entered without permission, the charge is fourth-degree.2Justia. New Jersey Code 2C:18-1 – Definitions The airport category is another one worth flagging. Walking past a security checkpoint into a restricted terminal zone, or stepping into an airport operations area without credentials, is a fourth-degree crime even if nothing else happened.1Justia. New Jersey Code 2C:18-3 – Unlicensed Entry of Structures; Defiant Trespasser; Peering Into Dwelling Places; Defenses
The word “structure” in the statute is also broader than ordinary usage suggests. It covers buildings, rooms, ships, vessels, cars, vehicles, airplanes, and any place used for carrying on business. A separately secured portion of a larger building counts on its own, so entering a locked office inside a public lobby can support a charge even though the lobby is open to everyone.2Justia. New Jersey Code 2C:18-1 – Definitions
Fourth-Degree Penalties
A fourth-degree conviction carries up to 18 months in state prison and a fine of up to $10,000.3Justia. New Jersey Code 2C:43-6 – Sentence of Imprisonment for Crime; Ordinary Terms4Justia. New Jersey Code 2C:43-3 – Fines and Restitutions
Those are the ceilings. In practice, a first-time offender rarely sees the inside of a state prison on a fourth-degree trespass. New Jersey law creates a presumption of non-incarceration for anyone convicted of a third- or fourth-degree crime who has no prior criminal record. The judge has to find that imprisonment is necessary to protect the public before sending a first offender to prison on a charge at this level. Probation is the more typical disposition.5Justia. New Jersey Code 2C:44-1 – Criteria for Withholding or Imposing Sentence of Imprisonment
Probation on a fourth-degree crime is not a free pass, though. The court can require up to 364 days in county jail as a condition of probation, along with community service, restitution, and other terms.6Justia. New Jersey Code 2C:43-2 – Sentence in Accordance With Code; Authorized Dispositions
Disorderly Persons Penalties
When the trespass doesn’t involve one of the elevated property types, the charge is a disorderly persons offense. The jail cap is six months, served in a county facility rather than state prison.7Justia. New Jersey Code 2C:43-8 – Sentence of Imprisonment for Disorderly Persons Offenses and Petty Disorderly Persons Offenses The fine tops out at $1,000.4Justia. New Jersey Code 2C:43-3 – Fines and Restitutions A probation sentence can include up to 90 days in jail as a condition, well below the 364-day cap that applies to indictable crimes.6Justia. New Jersey Code 2C:43-2 – Sentence in Accordance With Code; Authorized Dispositions
Mandatory Court Assessments
The fine is not the whole bill. New Jersey imposes several assessments on every criminal conviction, and the judge has no discretion to waive them. For a non-drug trespass conviction, expect at least these:8New Jersey Courts. Manual on New Jersey Sentencing Law
- Violent Crimes Compensation Board assessment: $25
- Safe Neighborhoods Services Fund assessment: $75 for a crime, $50 for a disorderly persons offense
- Law Enforcement Officers Training and Equipment Fund penalty: $30
- Victim of Crime penalty: $50
Those four alone add $180 to a fourth-degree conviction and $155 to a disorderly persons conviction before the judge adds any discretionary fine. Counties may tack on additional court costs.
What the State Has to Prove
A conviction under 2C:18-3a requires the prosecution to establish two things: that you entered or remained inside a covered location, and that you knew you had no permission to be there. “Knowingly” is the operative mental state. A genuine and reasonable belief that you were allowed in defeats the knowledge element. Walking into the wrong office in an unfamiliar building after misreading a directory is a different situation from slipping past a locked door after hours, and the statute treats it that way.1Justia. New Jersey Code 2C:18-3 – Unlicensed Entry of Structures; Defiant Trespasser; Peering Into Dwelling Places; Defenses
The statute also reaches people who entered legally and then hid or stayed after their permission expired. The prosecution does not have to prove you planned to steal anything or cause damage. The unauthorized presence itself is the offense.
Defenses That Can Beat the Charge
The statute spells out three affirmative defenses. The defendant has the burden of raising them, but each one, if established, defeats the charge:1Justia. New Jersey Code 2C:18-3 – Unlicensed Entry of Structures; Defiant Trespasser; Peering Into Dwelling Places; Defenses
- The structure was abandoned at the time of entry. This comes up most often with vacant commercial properties and condemned buildings.
- The structure was open to the public, and you complied with all lawful conditions on access. A customer in an open store cannot be charged with trespass unless they violated a posted condition or were asked to leave and refused.
- You reasonably believed the owner, or someone with authority, would have let you in. The belief has to be objectively reasonable, not merely sincere.
The reasonable-belief defense is where most contested trespass cases are actually fought. A friend-of-a-friend saying “go ahead, nobody will care” can support it. Climbing through a broken window at 2 a.m. will not.
After the Case: Record, Background Checks, and Expungement
A fourth-degree crime is an indictable offense, which shows up on background checks as the New Jersey equivalent of what most other states call a felony. A disorderly persons conviction creates a permanent criminal record too, even though it is not indictable.
Federal law does not cap how far back employers can look at criminal convictions. Some states limit reporting to seven years, but the federal Fair Credit Reporting Act has no such cap for convictions, so a trespass conviction can follow you on background checks indefinitely unless it is expunged. On the housing side, HUD guidance prohibits blanket bans on renters with criminal records, but landlords can still deny applicants case by case after weighing the nature of the offense, the time since conviction, and evidence of rehabilitation. Property offenses fall into that discretionary-denial zone.
New Jersey allows expungement of both indictable offenses and disorderly persons offenses after a waiting period. Under current law, you generally wait five years from completing your sentence, finishing probation or parole, or paying all fines, whichever comes last. The waiting period applies to both fourth-degree crimes and disorderly persons offenses.9New Jersey Courts. Expunging Your Court Record New Jersey has also been moving toward an automated “clean slate” process for older convictions, and the eligibility rules in this area have been actively changing, so check the current law before you file.
