Lower Buckeye Jail Roster Lookup

Lower Buckeye Jail Overview

Lower Buckeye Jail is operated by the Maricopa County Sheriff's Office at 3250 West Lower Buckeye Road in Phoenix. MCSO describes it as the largest detention facility in Arizona. Its population is predominantly male, but research notes females housed in the Mental Health Unit and Infirmary, plus remanded male and female juvenile inmates.

The facility opened in 2005 and is listed at 670,237 square feet. It houses nonsentenced male minimum and medium general population, administrative restrictive housing, nature-of-charge inmates, fully sentenced working inmates, disciplinary restrictive housing, and medical or mental-health populations.

Lower Buckeye Jail Capacity and Population

MCSO lists Lower Buckeye Jail at approximately 2,427 beds. Research did not locate a current facility-specific daily population count, so countywide adult jail ADP should be used only as system context. The official facility facts also identify a 60-bed medical infirmary and a 255-bed mental-health unit.

How to Look Up an Inmate at Lower Buckeye Jail

Use the official MCSO Inmate Information page for Lower Buckeye Jail custody. The search requires either a valid booking number or exact name and date of birth. It does not replace ADCRR, BOP, or ICE lookup tools after transfer out of county jail custody.

1. Search by booking number using one letter followed by six numbers.
2. Or search by first name, last name, and DOB in YYYYMMDD format.
3. Confirm the person is currently assigned to Lower Buckeye Jail before mailing or planning a visit.
4. For no match, call SIMS at 602-876-0322 and check court records, mugshots, VINELink, ADCRR, BOP, or ICE ODLS when appropriate.

Lower Buckeye Jail Address and Contact

Lower Buckeye is also the central mailroom address used by MCSO for incoming inmate mail. Use the jail information line before assuming a person's housing location, medical location, or mail eligibility.

Visiting Someone at Lower Buckeye Jail

MCSO social visitation is remote video through ViaPath/GettingOut. Onsite video visits were listed as suspended in inspected MCSO visitation material. Attorney and professional remote visitation may be verified at the Lower Buckeye visitation center with a State Bar card and government ID.

Mail, Phone, and Money at Lower Buckeye Jail

General incoming mail for MCSO inmates uses the Lower Buckeye address. Non-legal mail must follow MCSO postcard rules, including size limits and blue or black ink. Books must come from the publisher, and photographs must meet the MCSO photo limits and marking requirements.

Verify current rules through MCSO's Information for Families, Visitation, and Inmate Account pages before mailing, visiting, or depositing funds.

Booking and Intake at Lower Buckeye Jail

Initial police custody booking generally occurs at the Intake, Transfer and Release Facility, then inmates may be transferred to Lower Buckeye based on classification, medical or mental-health needs, working-inmate status, juvenile remand, or security factors. Medical concerns should be raised during booking because MCSO does not accept outside medication for inmate consumption.

Lower Buckeye is also important after booking because several MCSO system functions point back to it even when the inmate is housed elsewhere. The central mailroom address uses Lower Buckeye, so a Watkins, Estrella, Towers, Fourth Avenue, ITR, or 512 Facility inmate may still receive general incoming mail through the Lower Buckeye address. That makes the booking number and current name spelling critical. Mail without a correct booking number can be delayed, rejected, or routed poorly.

The medical and mental-health role of Lower Buckeye should not be treated as a public medical-status lookup. MCSO and county Correctional Health Services handle medical care inside custody, while public jail pages do not publish private health details. Family members with urgent medical information should use the official county medical-condition reporting route described in the research and should still confirm custody through MCSO before submitting details tied to the wrong person or stale booking.

About Lower Buckeye Jail

Lower Buckeye includes four 102-bed direct-supervision dormitories, twelve podular remote housing units, outdoor recreation, classrooms, chapel and medical clinic space on each level, negative-airflow rooms, ADA-compliant rooms, more than 800 cameras, more than 2,000 doors and locks, and 11 elevators. It also houses working inmates and a fully accredited high school for juvenile offenders.

MCSO describes Lower Buckeye as the largest detention facility in Arizona, with approximately 2,427 beds and about 670,237 square feet. Its population is not one simple group. The research identifies nonsentenced male inmates, sentenced working inmates, people in administrative or disciplinary restrictive housing, medical and mental-health inmates, and remanded juvenile inmates. That range is why the facility page needs more than a roster link. Classification, health care, work status, and court status all affect what a person can do from custody.

For records research, Lower Buckeye should be separated from state prison and federal custody. A person housed here is still in the MCSO county jail system unless transferred. If a court sentence sends the person to ADCRR, the ADCRR Inmate Data Search becomes the right locator. If the person is federal or immigration custody, BOP or ICE ODLS may be needed. Lower Buckeye's role as a jail and mail hub does not make it a universal custody locator.

Lower Buckeye also carries several details that affect families but are easy to miss in a basic inmate search. The research identifies a 60-bed infirmary, a 255-bed mental-health unit, negative-airflow rooms, ADA-compliant rooms, and a juvenile high school. Those details explain why a person may be housed here even if the arrest, court appearance, or release process began somewhere else in the MCSO system.

Before sending money, mail, books, newspapers, magazines, or photographs, confirm both custody and current MCSO rules. The research notes strict postcard limits, publication rules, photograph limits, and prohibited markings or content. It also notes that current commissary or deposit fee amounts were not captured. Unsupported fee amounts should not be assumed from older vendor pages or third-party summaries.
