Inmate Housing in the Federal Bureau of Prisons

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

Federal prisoners live in one of four housing types the Bureau of Prisons defines by square footage: a single-occupancy cell, a double-occupancy cell or room, a cubicle partitioned out of a dormitory, or an open dormitory the Bureau calls “multiple occupancy housing.” Which one a person gets is driven by the institution’s design and security level — dormitories and cubicles at camps and low-security institutions, cells with locking doors at mediums and penitentiaries — and the specific bed is assigned by unit staff, not by Receiving and Discharge.

This page covers where people actually live: the unit, the difference between a cell and an open bay, how the first assignment is made and by whom, how a bunk or cell change actually happens, and what can override a person’s preference. Everything is sourced to the Bureau’s own Program Statements and to 28 C.F.R., with a page cite you can check. A Program Statement is agency policy, not law — the regulation binds the Bureau, and the Program Statement is the Bureau’s instruction for applying it.

The four housing types the Bureau actually recognizes

The Bureau’s capacity policy is the only document that defines these terms with numbers attached, and it was reissued on 19 March 2026 as PS 1060.13, Physical Capacity for Bureau Facilities, rescinding the June 2025 edition. Here are the definitions, verbatim in substance:

Housing type	Definition	Square footage	Standard furniture
Single occupancy	A room or cell to be occupied by one person. Any use of single cells must be documented on the BP-A1140 capacity form.	Less than 120 sq ft, ordinarily 50 sq ft or more	Desk, single bunk, one locker
Double occupancy	A room or cell to be occupied by two people. Bureau physical capacity is ordinarily based on double occupancy unless there is a programmatic or security reason for single.	Less than 120 sq ft, 55 sq ft or more	Shared desk, double bunk, two lockers
Cubicle housing	The partitioning of a dormitory housing area into spaces. Partitions are typically concrete block or another approved permanent material — fixed furniture arranged to look like a cubicle does not count.	Less than 120 sq ft, 45 sq ft or more	Same as the occupancy above
Multiple occupancy (“open dormitory”)	A room, cell or area of 120 sq ft or more that is partitioned. The most common form is an open dormitory.	120 sq ft or more; capacity = total square footage ÷ 60, rounded, then raised to the next even number	Bunks, lockers, shared day space

Source: PS 1060.13 at pp. 3, 5. Our full explainer on that policy is physical capacity for Bureau facilities.

Two numbers from that policy are worth pulling out because they are checkable and almost never stated correctly. A standard cubicle wall is 5 feet 4 inches high, built from concrete masonry units under Bureau guidelines (PS 1060.13 at p. 3) — not the waist-high partition people often describe. And an open dormitory’s rated capacity is its total square footage divided by 60, measured from wall to wall including hallways and walkways, then rounded and raised to the next even number unless there is a documented programmatic or security reason for an odd count (PS 1060.13 at p. 5). That divisor is the closest thing the Bureau has to a per-person space standard in open housing.

The policy also draws lines that matter when a unit gets crowded. Temporary housing — cots placed in TV rooms, gyms or other ancillary areas during crowding or an emergency, trailers placed on site during construction, and additional people placed in cells designed for two — is not counted in an institution’s physical capacity at all (PS 1060.13 at pp. 3–4). Administrative housing supports the mission but is not available for direct admission: the Special Housing Unit, the infirmary, Receiving and Discharge and holding cells (PS 1060.13 at p. 3). The SHU is explicitly not permanent housing; when someone is placed there they receive a quarters assignment but keep their housing-unit team assignment, and the institution’s physical capacity does not change (PS 1060.13 at p. 4).

Cells and open-bay dormitories, by security level

The generalization people repeat is roughly right, and it is worth stating precisely: lower-security institutions are built around open or cubicled dormitories, higher-security institutions around cells with locking doors, and a good number of institutions have both in different parts of the compound. What drives it is the facility’s design and mission, not an individual’s preference.

• Federal prison camps and minimum security. Dormitory housing, usually cubicled, no perimeter fence in most cases. See minimum security federal prisons.
• Low security federal correctional institutions. Predominantly dormitory or cubicle housing, double-fenced perimeters. See low security federal prisons.
• Medium security FCIs. Predominantly cells, typically two people to a cell. See medium security federal prisons.
• United States penitentiaries and high security. Cells, close staff supervision. See high security federal prisons.
• Administrative facilities — detention centers, medical centers, the ADX. Mixed by mission. See administrative security prisons and federal medical centers.

The Bureau’s own capacity policy explains why a cell can hold anywhere from one to a large group: physical capacity for cells, rooms and cubicles is “ordinarily based on double occupancy, unless there is a programmatic and/or security reason for single occupancy,” and any single-occupancy space must be specifically documented on the BP-A1140 form — in the absence of that note, “all will be assumed double occupancy” (PS 1060.13 at p. 5). Single cells exist, but they are the documented exception, and they are ordinarily assigned for a program or security reason rather than on request.

Practically, the trade-off between the two settings is the one people actually feel. A dormitory means constant noise, no visual privacy, and open access to whatever is in your area — which is why lockers and locking devices matter more there. A cell means a door, usually a toilet and sink, a real measure of quiet, and a much smaller pool of people to get along with, which cuts both ways: if a cellmate is a problem, there is nowhere to go. Neither is a security level in itself, and how a person’s security level is calculated is a separate subject covered on our federal prison security levels page and in the security designation and custody classification explainer.

Inside the unit: what is actually posted on the wall

A housing unit is not just a place to sleep — it is an administrative unit with its own staff, its own schedule and its own written rules, and a surprising amount of what a new arrival needs is physically posted on the wall. The Unit Manager is required to ensure that unit rules and regulations appear in all orientation materials and are posted on inmate bulletin boards in both English and Spanish, covering at a minimum (PS 5321.10 at pp. 5–6):

• dress code and appropriate clothing
• quiet hours and lights out
• room and cell assignments
• room and cell sanitation expectations
• personal property limits and authorized areas of storage
• storage of excess legal materials
• intra-unit visiting limitations

Prison Rape Elimination Act announcements and information must also be posted in English and Spanish on the unit bulletin board. Separately, the Unit Manager develops and continuously maintains a posted schedule of unit programs, services and activities — the staff schedule (with a photo display identifying each Unit Management staff member by position), unit open house hours, Unit Management counseling groups and programs, and classification and program review dockets (PS 5321.10 at p. 5). Sanitation standards, orderly responsibilities, inspection frequency and how sanitation is assessed are posted as well (PS 5321.10 at p. 6).

Counts organize the day. Every institution conducts at least five official counts in each 24-hour period, with an additional count at 10:00 a.m. on weekends and holidays; the daily 4:00 p.m. count and the weekend and holiday 10:00 a.m. count are stand-up counts, and institutions with secure cell space lock people in their cells for all official counts unless they are on an out-count in food service, the hospital or the visiting room (PS 5500.14 at p. 27). Each count is conducted by at least two officers, with no movement while it runs. If a count does not clear twice, the Operations Lieutenant sends a third staff member, and if it still does not clear the institution can go to a bed-book (picture card) count, in which every person is identified against their bed-book picture card (PS 5500.14 at pp. 27–28). Our page on what to know about inmate counts covers the full schedule.

Storage is a rule, not a courtesy. 28 C.F.R. § 553.11(b) requires staff to “set aside space within each housing area for use by an inmate,” and that designated area “shall include a locker or other securable area in which the inmate is to store authorized personal property.” People are allowed to purchase an approved locking device for property storage in regular living units. Staff may not let property accumulate to the point of becoming a fire, sanitation, security or housekeeping hazard, and the amount of space provided depends on the number of people assigned to the housing area (PS 5580.10 at pp. 2–3). Based on available storage, the warden may set local limits on how much commissary, newspapers and magazines a person may keep. See inmate personal property.

Your unit team: who controls what

Almost every housing question a person or family has resolves to “which staff member owns this decision.” The Bureau’s Unit Management Manual, PS 5321.10, answers that directly, and the answer is the most useful thing on this page.

Role	What they control	Where they are
Unit Manager	Directs and manages the housing unit; responsible for unit operation and security; ordinarily chairs each initial classification and program review; ordinarily chairs the Unit Discipline Committee; supervises the rest of the unit team	In the unit daily during scheduled hours
Case Manager	Classification material, progress reports, release plans, Central Inmate Monitoring, security and custody classification, victim and witness notification, First Step Act time-credit eligibility, PATTERN generation, needs assessments; schedules the team meetings	In the unit daily during scheduled hours
Correctional Counselor	Day-to-day adjustment, living quarters, sanitation, work assignments; the unit expert on locally maintained personal property and trust fund activity; coordinates visiting-list approvals and runs the NCIC checks; ordinarily runs a structured group in each assigned unit at least once per quarter	In the unit daily during scheduled hours
Unit Officer	The custody post in the unit; delivers the safety orientation and unit security overview to every new arrival; conducts counts; directs new arrivals to their assigned cell or bunk	The unit officer’s station off the day room
Unit Secretary	Unit administrative support	In the unit

Source: PS 5321.10 at pp. 4–8.

Two access rules are worth knowing because they give a family a documented point of contact. First, Unit Managers, Case Managers and Correctional Counselors are ordinarily to be accessible in their assigned unit daily during their scheduled hours, including touring the unit and holding open houses, with open house ordinarily held Monday through Friday, excluding holidays; the quarterly Unit Management staff schedule is signed by an Associate Warden and “must be posted in a highly-visible location in the unit” (PS 5321.10 at pp. 8–9). Second, anyone housed in the Special Housing Unit, the Health Services area or another secure unit “must ordinarily be visited by a member of their assigned Unit Management when that staff member is scheduled to work,” and their Unit Manager must visit at least weekly (PS 5321.10 at p. 8). Someone in a community hospital must be visited by a unit team member at least weekly; someone in a local jail must be visited by their Unit Manager or acting Unit Manager at least weekly.

Applied Insight — Christopher Zoukis, JD, MBA, Managing Director: When a housing problem is not moving, the fix is almost always addressing it to the right staff member in writing rather than escalating louder to the wrong one. Bunk and cell moves belong to the Correctional Counselor. A medical restriction that should drive a lower bunk belongs to Health Services and is entered on the Medical Duty Status form, not decided by unit staff. A separation concern belongs to the Case Manager and the Central Inmate Monitoring file. Sending all three to the officer at the desk produces nothing, and a written request creates a dated record that a later administrative remedy can point to.

How the first housing assignment is actually made

The common belief is that Receiving and Discharge assigns the first cell. It does not. Under the Bureau’s Receiving and Discharge Manual, reissued 7 May 2026, the sequence before anyone is assigned a housing unit is explicit: “Prior to assigning an inmate to a housing unit, the CMC and SIS Lieutenant are to review and identify any high profile and other special interest or security cases requiring additional scrutiny. Once these cases are cleared by the CMC and SIS Lieutenant, the AW or designee will review and approve the inmate unit assignment” (PS 5800.19 at p. 22). The Case Management Coordinator and the Special Investigative Services Lieutenant screen it; the Associate Warden or a designee approves it.

That approval is fed by the intake screening. Staff making quarters assignments for a newly arrived person “must review the result of the current intake screening to ensure restrictions are noted prior to assignment” (PS 5295.01 at p. 4), and the entire point of the social interview under 28 C.F.R. § 522.21(a)(1) is to determine whether there are non-medical reasons to house someone away from general population. Medical reasons come from the 24-hour Health Services screening, which is required to address restrictions on housing and temporary work assignments (28 C.F.R. § 522.21(a)(2); PS 6031.06 at p. 19). Our page on the federal prison intake process walks that sequence in full.

Once the unit assignment is approved, the Unit Officer places the person in a specific cell or bunk on arrival in the unit, and delivers the safety orientation and unit security overview that same day, no later than lights out (PS 5290.14 at p. 9). If a new arrival goes first to a central A&O unit or to a temporary unit because the assigned unit has no bed space, moving to the assigned unit later triggers a fresh safety orientation from the receiving Unit Officer, and unit orientation by the Unit Manager, Case Manager and Correctional Counselor must be completed within seven calendar days of arrival in the assigned unit (PS 5290.14 at pp. 4, 9–10). Anyone reassigned to another unit inside the same institution gets unit orientation within seven calendar days and a new BP-S597 checklist.

Bunk assignment: top, bottom, and how a lower-bunk pass works

Nothing in national policy gives anyone a right to a bottom bunk, and there is no seniority rule written down. What exists is a clinical route. A lower bunk is a medical restriction, authorized by a clinician and entered on the Medical Duty Status (MDS) form in the electronic health record — the same mechanism that produces restrictions for housing closer to the medical unit, work limits and recreation limits (PS 6031.06 at pp. 26, 32). The clinician conducting the evaluation determines the need and documents the order; unit staff then implement it. That is why a bottom-bunk request made to the unit officer goes nowhere and the same request made through sick call sometimes works: the decision does not belong to the unit.

Two related populations have policy support for the same accommodation. For aging offenders, the Bureau directs that housing assignments be consistent with physical abilities and limitations — “access to lower tier cells, lower bunk passes, and wheelchair accessible cells” — and that cells and assistance devices be assigned so the person can navigate to Health Services, food service, commissary and education (PS 5241.01 at pp. 3, 7). See the aging offenders explainer. For people with disabilities, accessible housing is a Rehabilitation Act and Architectural Barriers Act question as well as a policy one; see management of inmates with disabilities. For someone who is pregnant, the Bureau’s Female Offender Manual provides that medical staff may recommend a change in housing closer to Health Services, or a lower bunk, for safety reasons (PS 5200.09 CN-1 at p. 25); activity limits are indicated through the Medical Duty Status function. See also women’s federal prisons.

Two shorter MDS statuses affect where a person spends the day rather than where they sleep. Medical idle is a maximum of three calendar days for recuperation from an acute illness or injury, restricting the person to quarters except for meals, religious services and medical call-outs. Medical convalescence is a maximum of 30 calendar days for extended recuperation, renewable if clinically indicated, with a follow-up visit scheduled before it expires (PS 6031.06 at p. 32). Neither is a housing change, but both are commonly confused with one. See medical care in federal prison.

How to change a cell or bunk — the actual route

The Correctional Counselor is the staff member who owns this. The counselor “monitors the inmate’s general adjustment, living quarters, sanitation, work assignments, and performance in assigned programming, which includes on-site visits,” and serves as the unit expert and coordinator on locally maintained personal property and trust fund activity (PS 5321.10 at p. 7). A move request goes to the counselor, in writing.

The mechanics of “in writing” changed in 2026, and this is the part every other page still has wrong. Under PS 5511.08, Inmate Request to Staff, reissued 19 March 2026 and rescinding a 1998 policy, a request to staff — the “cop-out” — is now submitted electronically through the Request to Staff Service in TRULINCS. Three rules attach (PS 5511.08 at p. 2):

• One request per department per day.
• A response is ordinarily completed within 30 calendar days if warranted.
• The paper BP-A0148 is now the exception: it is used by people the warden has exempted from electronic filing — for physical or mental incapacity, other extraordinary circumstances, or special security concerns such as SHU placement — and by anyone housed in a Protective Custody Unit, for whom the Request to Staff Service is not available.

If the request is denied and the reason is one the person can challenge, the route is the Administrative Remedy Program: informal resolution first, then a formal BP-9 Administrative Remedy Request, which must be completed and submitted within 20 calendar days of the date the basis for the request occurred. The form is obtained from institution staff, “ordinarily, the correctional counselor,” and is submitted to that same designated staff member. Where a person reasonably believes the issue is sensitive and their safety would be endangered if it became known at the institution, the request may go directly to the Regional Director. Our page on prison grievances walks the BP-8 through BP-11 sequence.

One point of etiquette is real but is not a rule: in most units, people ask the current occupant before requesting a move into a cell, and the request goes better when they have. That is unit culture, not policy, and it does not bind the counselor — our page on how to greet cellmates covers that side of it. What binds the counselor is the set of overrides below.

What can override a housing preference

These are the reasons a request gets denied that have nothing to do with seniority or conduct, and each one is written down.

Separations. The Central Inmate Monitoring system defines a “Separation” assignment as people “who may not be confined in the same institution (unless the institution has the ability to prevent any physical contact between the separatees) with other specified individuals” in federal custody or who may come into it (PS 5180.05 at p. 5). Separations are checked at intake against the CIM Clearance and Separatee Data, and staff may cross-check separatee names against an alphabetical list of everyone in the institution (PS 5295.01 at p. 3). A separation is not negotiable and staff will not explain it in detail. See Central Inmate Monitoring and separatees.

PREA risk. 28 C.F.R. § 115.42(a) requires the agency to use the intake risk screening “to inform housing, bed, work, education, and program assignments with the goal of keeping separate those inmates at high risk of being sexually victimized from those at high risk of being sexually abusive,” and subsection (b) requires individualized determinations about how to ensure each person’s safety. When someone is identified as at risk, Unit Management must review classification options including changes in housing units, cell assignments, work assignments and education assignments (PS 5333.01 at p. 34). The Correctional Counselor monitors the housing, work and programming assignments of people deemed at risk of sexual victimization and perpetration (PS 5321.10 at p. 8).

There is a hard limit attached to that, and it is one of the more useful rules on this page. Under 28 C.F.R. § 115.43(a), people at high risk for sexual victimization “shall not be placed in involuntary segregated housing unless an assessment of all available alternatives has been made, and a determination has been made that there is no available alternative means of separation from likely abusers” — and if the facility cannot conduct that assessment immediately, it “may hold the inmate in involuntary segregated housing for less than 24 hours while completing the assessment.” The Bureau documents the assessment on the BP-A1002, Safeguarding of Inmates Alleging Sexual Abuse and/or Harassment form, signed and dated by the warden and emailed to the Regional PREA Coordinator, who tracks PREA-related SHU placements (PS 5333.01 at p. 34). Where access to programs, privileges, education or work is restricted, the Captain must document what was limited, for how long and why. See protective custody and PREA and sexual abuse prevention.

Medical and disability needs. A Medical Duty Status restriction — lower bunk, housing closer to Health Services, accessible cell — is entered clinically and implemented by unit staff, and it outranks preference (PS 6031.06 at pp. 26, 32).

Program units. Residential programs run in dedicated units. Entering the Residential Drug Abuse Program means moving into the RDAP unit; other program and reentry units work the same way. A move into or out of one is a program decision made at a program review, not a bunk-change request.

Transgender and intersex housing reviews. PS 5321.10 no longer contains the 2024 edition’s instruction that the Unit Manager review transgender and intersex people’s work, programming and housing assignments with consideration for their own view of their safety. At each program review the Unit Manager now reviews work, programming and housing unit assignments “for all inmates including those deemed at risk of sexual victimization and perpetration” (PS 5321.10 at p. 4). See gender dysphoria management.

Race and cell assignment: what the rule actually is

The claim that inmate groups run cell assignments at higher-security institutions circulates widely, and it needs a clear answer, because it is not the law and it is not Bureau policy.

The binding regulation is 28 C.F.R. § 551.90: “Bureau staff shall not discriminate against inmates on the basis of race, religion, national origin, sex, disability, or political belief. This includes the making of administrative decisions and providing access to work, housing and programs.” Housing is named in the text. See the non-discrimination toward inmates explainer.

The constitutional standard is the same direction and stricter. In Johnson v. California, 543 U.S. 499 (2005), the Supreme Court held that strict scrutiny — not the deferential standard of Turner v. Safley — governs an equal protection challenge to a prison policy of racially segregating prisoners in cell assignments, reaffirming that “[t]he necessities of prison security and discipline are a compelling government interest justifying only those uses of race that are narrowly tailored to address those necessities.” The Court did not hold that prison officials may never consider race in any circumstance; it held that when they do, the government carries the burden of proving the classification is narrowly tailored.

What that means in practice: a housing assignment made or withheld on a racial basis is not a defensible correctional decision, and a person who believes one was made that way has a route — a written request to staff, then a BP-9 within 20 calendar days, then BP-10 and BP-11. Staff conduct that crosses into misconduct has its own reporting channel; see reporting staff misconduct. What the Bureau’s policy does authorize is a documented, individualized security judgment — a separation, a security threat group concern, a PREA risk determination — which is a different thing entirely and is recorded in the file where it can be reviewed.

When the unit changes around you

Housing is not static, and four things move people without anyone requesting it.

The Special Housing Unit. A SHU placement is administrative detention or disciplinary segregation, and the person keeps their housing unit team assignment while there (PS 1060.13 at p. 4). A member of the person’s Unit Management team ordinarily visits whenever that staff member is on duty, and the Unit Manager at least weekly (PS 5321.10 at p. 8). See solitary confinement and Special Housing Units and the Special Housing Units policy.

Lockdowns and modified operations. When an institution restricts movement, the unit becomes the whole world for a period. Our explainer on lockdowns and modified operations covers what the Bureau’s first dedicated lockdown policy requires.

Crowding. When population exceeds design, cots go into TV rooms and gyms and additional people go into two-person cells. The Bureau classifies all of that as temporary housing that does not count toward physical capacity (PS 1060.13 at pp. 3–4), which is why a crowded unit and a “full” institution are not the same statistic.

Transfers and closures. A transfer starts the housing question over: after a transfer, an initial program review is conducted within 28 calendar days of arrival at the new facility (28 C.F.R. § 524.11(a)(1); PS 5321.10 at p. 13), and ordinarily people within 60 days of their release date are not moved at all (PS 5800.19 at p. 14). Facility closures and mission changes move whole populations; see major federal prison closures and deactivations.

A housing decision made at a program review can be appealed. PS 5321.10 at p. 16 provides that “[t]hrough the Administrative Remedy Program, an inmate may appeal a decision made at initial classification or an inmate program review,” and program reviews run at least every 180 calendar days, or at least every 90 once within twelve months of the projected release date (28 C.F.R. § 524.11(a)(2)). Everyone gets at least 48 hours’ notice before appearing, and the docket is posted in the unit — which makes the program review the natural place to raise a housing issue that a cop-out has not solved. See unit team and program review.

Applied Insight — Christopher Zoukis, JD, MBA, Managing Director: The most common avoidable housing problem we see is a medical restriction that exists clinically but was never entered on the Medical Duty Status form. The person genuinely cannot use a top bunk, a provider agrees, and nothing changes — because unit staff implement what the record says, not what a person reports. The fix is unglamorous: a sick call visit, an explicit request that the restriction be documented on the MDS, and a written request to staff afterward asking the counselor to implement the documented restriction. Two records instead of one conversation.
