New Brunswick Criminal Trespass Attorney

Reviewed by William A. Proetta, Esq. · Updated October 2026

Criminal trespass under N.J.S.A. 2C:18-3 has three grades: defiant trespass after a warning, posting or fence is a petty disorderly persons offense (up to 30 days, $500 fine); knowingly entering or secretly remaining in a structure without permission is a disorderly persons offense (up to 6 months, $1,000); and the same entry into a dwelling, a school, a utility or other listed facility, or an airport’s secure area is a 4th-degree crime (up to 18 months, $10,000). Peering into a home’s window to invade someone’s privacy is also 4th degree.

Petty disorderly and disorderly persons trespass charges are heard in the municipal court of the town where the entry happened, whether that is South Plainfield, Edison Municipal Court at 100 Municipal Boulevard, or New Brunswick Municipal Court at 25 Kirkpatrick Street. A 4th-degree charge is indictable and goes through the Middlesex County Prosecutor’s Office to the Superior Court in New Brunswick. William Proetta Criminal Law handles trespass defense from our Edison office, with more than 15 years of criminal trial experience.

The Three Trespass Offenses

Unlicensed entry of a structure, 2C:18-3(a). Knowing you are not licensed or privileged to be there, you enter or secretly remain in a structure, a separately secured or occupied part of one, a research facility, utility company property, or the sterile or operational area of an airport. No intent to do anything inside is required. That is the line between trespass and burglary, which requires a purpose to commit an offense inside.

Defiant trespass, 2C:18-3(b). Knowing you are not licensed or privileged, you enter or remain in any place, indoors or out, where notice against trespass was given by:

1. telling you directly (in person, by letter or by a written ban);
2. posting signs in a way the law prescribes or that intruders are likely to see; or
3. fencing or another enclosure clearly designed to keep people out.

Peering, 2C:18-3(c). Looking into a window or other opening of a home or other overnight lodging to invade someone’s privacy, where a reasonable person inside would not expect to be seen.

The word that controls all three is “knowing.” The State must prove you knew you lacked permission. Confusion about a property line, a roommate’s invitation or an old key from a former lease can defeat that element.

Trespass Grades

There is no 3rd-degree trespass. Charges that sound more serious, such as entering a home to take something, are burglary or home invasion burglary, not trespass.

Consequences

• Jail is uncommon at the lower grades, and a first offender convicted of the 4th-degree crime has a presumption of non-imprisonment under N.J.S.A. 2C:44-1(e). No NERA, no Graves Act, no registration.
• Domestic violence. Criminal trespass is a predicate offense under N.J.S.A. 2C:25-19. Showing up at a former partner’s apartment after being told to stay away can lead to a restraining order and firearm seizure, in addition to the charge.
• Expungement. Trespass is not on the 2C:52-2(b) bar list. A trespass conviction, including a disorderly persons one, is not permanent; our Middlesex expungement page explains the waiting periods.
• Student and job consequences. A conviction can surface in background checks for school housing, employment and professional licensing, which is why we aim for dismissal or diversion.
• Immigration. Effects depend on the subsection and facts admitted; a non-citizen should get immigration advice before any plea.

Trespass Cases in Middlesex County

Who files. Trespass charges reach Middlesex municipal courts in two main ways. Police issue a summons after a call from a store, landlord, school or homeowner. Or a property owner or manager files a citizen complaint at the municipal court, which needs a judicial finding of probable cause before it proceeds. A familiar pattern in Edison and Woodbridge: store security at a shopping center on Route 1 or Route 9 hands someone a written no-trespass notice, the person returns months later, is recognized, and receives a defiant trespass summons.

Campus and housing. In New Brunswick, entering a Rutgers residence hall or academic building without authorization can bring both a municipal court charge and a university conduct case. In apartment complexes in North Brunswick and East Brunswick, disputes over guests, former tenants and lockouts often turn on whether permission was actually withdrawn.

Domestic cases. When the alleged trespass is at a current or former partner’s home, the person who made the complaint can seek a temporary restraining order at the Family Courthouse, 120 New Street, New Brunswick. That case runs on its own schedule beside the criminal charge, and police may take firearms under the order.

Indictable charges. A 4th-degree dwelling or school trespass is screened by the MCPO at 25 Kirkpatrick Street. Many are remanded to municipal court as disorderly persons trespass, which requires the county prosecutor’s consent on the record; others proceed to a grand jury in New Brunswick. Anyone held on a complaint-warrant is detained at the Adult Correction Center on Apple Orchard Lane in North Brunswick until release is decided.

Diversion

Conditional dismissal under N.J.S.A. 2C:43-13.1 fits most first-time disorderly persons and petty disorderly trespass charges, provided no domestic violence is involved and the person has no prior conviction or diversion. A 4th-degree charge can be addressed through Pretrial Intervention, applied for through the Middlesex Criminal Division before the first case disposition conference after arraignment; see our PTI page.

Defenses

The statute itself lists three affirmative defenses in 2C:18-3(d), and the “knowing” element supplies more.

• Abandoned structure. For subsection (a), the building was abandoned.
• Open to the public. The place was open to the public when you entered, and you complied with all lawful conditions on staying.
• Reasonable belief in permission. You reasonably believed the owner, or someone entitled to grant access, would have allowed you in.
• No notice. For defiant trespass, the State must prove actual communication, adequate posting or a fence designed to exclude. A ban that was never delivered, or a sign hidden behind shrubs, does not count.
• No knowledge. You did not know permission had been withdrawn, or reasonably believed a tenant or family member could invite you.
• Peering not proven. The 4th-degree peering count requires a privacy purpose and a setting where people inside would not expect to be seen.
