The Suffolk County Sheriff’s Office, with roots dating to 1683, is one of the county’s oldest public institutions. In Suffolk County, the Sheriff’s Office is primarily responsible for corrections, civil enforcement, inmate transport, and court security, while most routine patrol and emergency crime response are handled by the Suffolk County Police Department or local police agencies in the county’s eastern towns and villages.

With major correctional facilities in Riverhead and Yaphank, the Sheriff’s Office plays a central role in the county justice system. Programs, visitation rules, office procedures, and service details may change, so it is wise to check official Suffolk County Sheriff resources before visiting or relying on time-sensitive information.

Corrections

The Sheriff operates two major correctional facilities:

  • Riverhead Correctional Facility: 100 Center Dr, Riverhead, NY 11901
  • Yaphank Correctional Facility: 200 Suffolk Ave, Yaphank, NY 11980

Responsibilities include:

  • Housing pre-trial detainees and sentenced inmates.
  • Overseeing educational, treatment, rehabilitation, and re-entry programming.
  • Maintaining facility safety, security, transportation, and inmate support services.

Civil Enforcement

The Sheriff’s Civil Enforcement Bureau carries out court-ordered civil matters such as:

  • Serving summonses, subpoenas, warrants, and other legal documents.
  • Executing evictions and other court-directed actions.
  • Enforcing property executions, levies, and wage garnishments.
  • Conducting public sales or auctions when ordered by the court.

Courts & Judicial Security

The Suffolk County Sheriff helps keep the county’s court system operating securely by:

  • Providing courthouse and courtroom security.
  • Transporting inmates to and from court appearances.
  • Supporting the safety of judges, jurors, witnesses, court staff, and the public.

Law Enforcement Support

Although routine patrol duties are generally handled by SCPD or local police departments, the Sheriff’s Office also supports broader public-safety efforts through:

  • Apprehending fugitives and enforcing certain warrants and court mandates.
  • Assisting with inmate transport, judicial operations, and countywide enforcement needs tied to the courts.
  • Working with local, state, and federal agencies in joint operations and task-force activity.

Specialized Units & Community Programs

The Suffolk County Sheriff’s Office also runs or participates in a range of specialized and community-focused programs, which may vary over time, including:

  • K-9 units used for detection, security, and other enforcement support roles.
  • DWI and traffic-safety initiatives conducted through targeted enforcement efforts.
  • Emergency response teams for high-risk incidents within the correctional system.
  • Community outreach on subjects such as opioid awareness, youth safety, re-entry, and scam prevention.
