About MDC Guaynabo

MDC Guaynabo (Metropolitan Detention Center Guaynabo) is an administrative security facility located in Guaynabo, Puerto Rico. This Bureau of Prisons facility houses male inmates and currently has a population of 1,099 individuals. As part of the Southeast Region (SER), MDC Guaynabo serves as a pretrial detention facility and houses inmates awaiting trial, sentencing, or transfer to other institutions.

The facility operates as a Metropolitan Detention Center, which means it primarily handles pretrial detainees and inmates with shorter sentences or those awaiting transfer. MDC Guaynabo does not currently offer the Residential Drug Abuse Program (RDAP), and specific medical care level information is not specified in available records. As an administrative facility, it focuses on secure detention and basic programming rather than long-term rehabilitation programs typically found at other security levels.

Located in Guaynabo, Puerto Rico, the facility can be reached at 787-749-4480, with administrative correspondence directed to GUA-ExecAssistant-S@bop.gov. Visiting hours follow standard BOP policies, though specific schedules may vary and should be confirmed through the facility or the BOP website. Prison Professors can help defendants preparing for placement at MDC Guaynabo and their families understand what to expect during their time at this facility, providing valuable guidance on navigating the federal prison system and maintaining family connections.

Residential Drug Abuse Program (RDAP)

RDAP Not Available

MDC Guaynabo does not currently offer RDAP.

The Residential Drug Abuse Program (RDAP) is the Bureau of Prisons' most intensive substance-abuse treatment program. It is a 500-hour, unit-based program lasting 9 to 12 months, followed by community-based transitional treatment. Participants who successfully complete RDAP may be eligible for up to a 12-month reduction in their sentence under 18 U.S.C. § 3621(e).

Facilities that do not offer RDAP may still provide the Non-Residential Drug Abuse Program (NR-DAP), a less intensive outpatient-style treatment, or the Drug Abuse Education (DAE) course, a shorter psychoeducational program. Both can help demonstrate progress toward rehabilitation but do not qualify for the same sentence reduction as RDAP.

Medical Care

Medical care level information is being compiled.

Standard BOP Medical Services

Sick Call Process

Inmates request medical attention by submitting a cop-out (Inmate Request to Staff) or a sick call form, typically available in each housing unit. Sick call is held on scheduled mornings — a staff member triages requests and inmates are seen by mid-level providers or physicians based on need.

Emergency Care

All BOP facilities provide 24/7 emergency medical coverage. In a medical emergency, staff will initiate on-site treatment and arrange outside hospital transport if necessary. Inmates should notify any staff member immediately for emergencies.

Dental Services

Routine dental exams are provided on an annual basis, including cleanings and necessary X-rays. Emergency dental care — such as treatment for pain, infection, or trauma — is available on a priority basis. Elective procedures are limited and subject to approval.

Mental Health Services

Each facility has psychology staff who provide individual counseling, group therapy, crisis intervention, and mental health evaluations. Inmates can self-refer by submitting a cop-out to the Psychology Department. Inmates on psychiatric medications are monitored regularly.

Medications

Chronic care medications (e.g., blood pressure, insulin, psychiatric meds) are dispensed through a scheduled "pill line." Inmates must report at designated times to receive their medications. Over-the-counter medications are available through commissary; some may be prescribed at no cost.

Co-Pay Information

The BOP charges a $2.00 co-pay for inmate-initiated health care visits. Exemptions apply to follow-up visits requested by medical staff, emergency care, chronic care appointments, mental health contacts, preventive services, and prenatal care. Inmates with insufficient funds are not denied care.

Good to Know

Medical care quality and wait times vary by facility. Inmates with pre-existing conditions should bring documentation of their medical history, current medications, and treating physicians to assist with continuity of care during intake processing.

Application & Waitlist

Inmates must apply for UNICOR positions and there is often a waitlist. Priority is generally given to inmates with court-ordered financial obligations and those nearing release.

Benefits of UNICOR Participation

UNICOR participation is viewed favorably by staff and can positively impact time credits under the First Step Act, custody level reviews, and halfway house recommendations.

UNICOR Availability

Not all federal facilities have UNICOR operations. Contact MDC Guaynabo to confirm current UNICOR availability and operations.

First Step Act Time Credits

The First Step Act (FSA) allows eligible inmates to earn time credits toward early release or transfer to supervised release (halfway house or home confinement) through productive work assignments, educational programs, and vocational training.

10 – 15 days of credit per 30 days

Eligible inmates earn 10 days of time credits for every 30 days of successful participation in Evidence-Based Recidivism Reduction (EBRR) programs or productive activities. Inmates assessed as minimum or low risk earn an enhanced rate of 15 days per 30-day period.

Work assignments — including institutional jobs and UNICOR — count as productive activities under the FSA. Combined with program participation, these credits can meaningfully reduce time served. Eligibility depends on factors including offense type, risk assessment score, and disciplinary record.

  • Once added, you will receive an email invitation from CorrLinks, the external-facing system that connects to TRULINCS.
  • Create a free CorrLinks account at corrlinks.com and accept the inmate's contact request.

Limitations
