New Jersey's treatment prison for men sentenced for sex offenses, in Avenel — next to East Jersey State Prison and separate from the co-located Special Treatment Unit, so confirming which facility holds the person matters.

Statewide rules that apply at every New Jersey state prison

These rules are set by NJDOC and apply at every unit. The full list — including all permitted and prohibited items and the approval process — is in Visiting in New Jersey.

Dress code

Tops must cover the shoulders and midriff — no tank, tube, halter, or low-cut tops, and nothing transparent, fishnet, skin-tight, or hooded.
Bottoms must cover from the waist to the knee — shorts must be Bermuda-style ending at the knee, and skirts and dresses must reach the knee when seated; no cargo-style pants, and nothing low-rise that exposes the midriff or buttocks.
Nothing resembling what incarcerated people, officers, or other workers wear — no military or uniform-style clothing, and nothing in khaki, orange, gray, or camouflage.
No hats or headgear (except religious or medical), no flip-flops, backless sandals, wheeled shoes, or steel-toed boots, and nothing with offensive or illegal-activity messages.

ID: Every adult visitor needs a photo ID — a driver's license, state non-driver ID, passport, photo Medicaid card, or employer photo ID (a Social Security card is not accepted). Every visitor, adult or child, must be on the incarcerated person's approved list.
What to bring: Almost nothing comes into the visit room — no phones, money (cash or coin), purses, photos, or food. A clear plastic or zip-lock bag may hold authorized items, and lockers are provided; life-sustaining medication such as an inhaler is handed to the visit supervisor.
Scheduling: The incarcerated person designates the visitors, and everyone must be on the approved list (a criminal record must be disclosed but is not an automatic bar). Visits are by appointment only — scheduled with the facility at least 48 hours ahead — and the number of visitors allowed at once varies by facility (commonly up to four adults plus children, sometimes fewer).

Full statewide rules: Visiting in New Jersey

Overview

The Adult Diagnostic and Treatment Center, in Avenel, is a New Jersey prison that holds men sentenced for sex offenses and provides a court-ordered treatment program under the state’s Sex Offender Act. It opened in 1976 and held about 424 men as of January 1, 2026. The facility is next to East Jersey State Prison in Avenel.

A separate facility, the Special Treatment Unit, is also in Avenel but is not the same place: it holds people who have been civilly committed after their sentences end under a different state law. ADTC holds people serving criminal sentences, and the two are run separately — so the first step is confirming which facility holds the person.

About ADTC

It is a specialized treatment facility. ADTC provides a court-ordered treatment program under the New Jersey Sex Offender Act for the men sentenced there.
It is next to East Jersey State Prison. Both are in Avenel; confirm the person is at ADTC (8 Production Way) and not the neighboring prison.
It is separate from the Special Treatment Unit. The Special Treatment Unit, also in Avenel, is a different facility for people civilly committed after their sentences, with its own visiting.
