The Marathon Detention Center is a detention center located at 3981 Ocean Terr Marathon, FL which is operated locally by the Monroe County Sheriff's Office and holds inmates awaiting trial or sentencing or both. Most of the sentenced inmates are here for less than two years. Monroe County accepts inmates from surrounding towns, Marathon Police Department, and the US Marshal's Service.

New detainees arrive at the jail regularly, with some being released on bail, placed under pretrial services caseloads, supervised by probation agencies, or released on recognizance with a court appearance agreement. Those who are not released await their court appearances at the jail, receiving accommodations including bedding and meals.

The Sheriff's Office provides law enforcement services across the Florida Keys, an area encompassing approximately 125 miles of islands extending from the southern tip of Florida. The primary thoroughfare, U.S. Highway 1, runs from Florida City to Key West, connecting the islands via 42 bridges. To effectively serve the unique population of the Keys, the Sheriff's Office operates state-of-the-art detention facilities located in Stock Island, Marathon, and Plantation Key. Additionally, the main Sheriff's Office Administration building is situated on Stock Island, with patrol substations strategically placed on Cudjoe Key, Marathon (Key Vaca), Islamorada, and Plantation Key.

The primary objective of classification within the correctional facility is to assign inmates to the type of housing that best meets their needs while ensuring reasonable protection for all inmates and others. Each inmate undergoes an interview with the Classification Department following their first appearance. The classification decision relies on comprehensive information, including self-reported medical history, criminal history, past institutional behavior, and current charges. The Monroe County Sheriff's Office provides a comprehensive 56-page Inmate Handbook, which is readily available to inmates and their families, outlining facility rules, procedures, and available services

Once the classification level is determined, inmates receive a copy of the decision. Every thirty days, each inmate is reclassified based on their behavior, additional charges, officers' comments, and any new medical issues. Inmates have the right to appeal their classification in writing within ten days of the primary classification or reclassification, addressing the appeal to the Classification Department under "Appeal of Classification." No inmate is allowed to possess money, checks, money orders, or any other legal tender. Instead, all funds are receipted and deposited into an account upon entry into the facility, with a $20.00 processing fee. This money can be used for purchasing commissary items.

Family and friends may deposit money into an inmate's account using a debit or credit card via phone, the internet, or in person using a special kiosk at the Stock Island Detention Center. Instructions for these methods are available online. Additionally, money orders can be dropped off at the middle and upper Keys detention facilities, provided they include the inmate's name as indicated on their I.D. and the complete name and mailing address of the sender. Money orders are no longer accepted at the Key West facility, and personal checks are not accepted at any facility.

All inmate property is stored securely while the inmate is held in the facility and is returned upon release or transferred with the inmate if moved to another facility. Upon booking, inmates are allowed to keep specific personal items, including eyeglasses, one simple wedding band, plain white socks if already worn, and one plain white short-sleeved t-shirt if worn at the time of booking.

Inmates cannot bring their medication into the facility. The contracted healthcare provider, Prison Health Services (PHS), assesses the inmates' medical needs at intake. If immediate medication is necessary, the doctor is notified, and appropriate medications are ordered promptly.

The use of telephones is a privilege. Inmates can use the phone to notify family members, or their attorneys, or to arrange for a bond. Any misuse of the telephone, including making obscene, threatening, or harassing calls or damaging equipment, will result in the loss of telephone privileges and possible criminal prosecution. Inmate telephones are managed by a third-party contractor, ICSolutions, and instructions for setting up an account are available online. Customer service for blocking or unblocking inmate calls is available at (888) 506-8407.

Inmates are permitted to receive four paperback books and four magazines each month, provided they are sent directly from the publisher or a legitimate retailer. Hardcover books are not allowed. Any publications exceeding these amounts or sent from unauthorized sources will be returned to the sender. Prohibited materials include sexually explicit content, instructions for making explosives or drugs, advocacy of violence within the facility, materials that incite serious disruption or violence, and those promoting racial, religious, or national hatred.

Outgoing and incoming mail is inspected for contraband or security breaches under the Florida Model Jail Standards, except legal mail, which is opened in the presence of the inmate if necessary. Inmates also have access to a variety of free reading materials available in their housing area and on the inmate tablets. Family members and friends can contribute paperback books to the facility's library by donating them to the Programs Department. Although these books are not reserved for any particular inmate, they are added to the general library collection.

Educational programs available include Adult Basic Education (ABE), which covers reading, writing, and arithmetic at the elementary and junior high school levels; General Education Development (GED), which prepares individuals for the GED test with English, Mathematics, Science, and Social Studies; and literacy training, which offers one-on-one tutoring to help individuals learn to read or improve their reading skills. Inmates interested in these programs should submit an Inmate Request Form to the GED Instructor via the Programs Director.
