Montana Prison Classification and Housing: How Placement Works

When someone you love is sentenced in Montana, one of the first questions families ask is where the person will actually be sent, and why. The answer is classification, the process the prison system uses to assign each person a custody level and a facility. Montana is a small, rural system that runs men through a diagnostic intake unit at the state prison, assesses each person's risks and needs, and assigns a custody level, with many people placed in pre release centers and other facilities rather than the main prison. This guide explains how classification and housing work in Montana, run by the Department of Corrections, from reception through the custody levels and how people move between them, along with how county jail and federal classification differ, written plainly by people who understand the system from the inside.

It starts with assessment and a diagnostic intake unit

Almost no one goes straight to a permanent placement in Montana. People committed to the Department of Corrections are first assessed to determine where they should go, including at a dedicated assessment center that evaluates new commitments for appropriate placement. For men headed into secure custody, intake happens at the Martz Diagnostic Intake Unit at Montana State Prison in Deer Lodge, where arriving inmates are assessed and then assigned to an appropriate living area within the facility. Women are received at Montana Women's Prison in Billings. During intake, staff complete the evaluations that drive classification, and case managers work with each person to develop an individualized case plan. For families, the key thing to understand is that intake and assessment are a temporary processing stage, and it is worth waiting for the permanent placement to settle before making visiting plans.

Montana's custody levels

Montana classifies people into custody levels that run from minimum, through medium, to close and maximum custody, with the state prison operating several custody levels across its compounds. At the main men's prison, lower risk people are housed on what is known as the low side, with units focused on programming, work, treatment, and accommodations, while higher risk people and those needing more supervision are housed on the high side, and there is separate locked and restrictive housing for those who must be closely managed. The prison also runs a work and reentry center outside the main perimeter, where minimum custody people take part in ranch and farm work. Because Montana is a small system, custody level also determines whether a person stays at the state prison or goes to a pre release center, a regional facility, or a contracted prison. The custody level shapes nearly everything about daily life, so it is one of the most important things for a family to understand.

How the placement decision is made

Montana uses a classification system that assesses each person's risks and needs to determine custody level, housing assignment, and program placement. The factors include the offense, criminal history, sentence length, behavior, any involvement with a security threat group, and medical and mental health needs. Case managers develop an individualized case plan and monitor progress over time. Because the state operates only a few secure facilities and relies on a network of pre release centers, regional facilities, and contracted prisons, the placement decision is partly about matching a person to the limited bed space available at the right custody level. A person does not get to choose their facility, and Montana is a very large state geographically with few facilities, so a person can easily be held many hours from home across the state. The practical reality for families is that the assessment, the custody level, the available beds, and conduct over time all shape where a person goes.

Housing types and moving between levels

Montana houses people in a range of settings depending on custody level and needs. Most people live in general population, in dormitories or cells depending on the unit and level, with units organized around programming, work, treatment, chemical dependency, sex offense programming, and accommodations needs, while those who must be separated for safety or discipline are held in restrictive housing or a secure adjustment unit, people designated as vulnerable receive additional observation and support, and people with mental health needs transitioning back to general population are housed accordingly. Montana has the death penalty and a small death row, with death sentenced people held in secure housing, though the state has not carried out an execution in many years. Movement between custody levels happens through reclassification, where staff review a person's behavior, time served, and progress and adjust the level, which can move a person to a different unit, a pre release center, or another facility. For most people, steady good conduct lowers the custody level over time and opens the door to lower security settings, work, pre release, and reentry. For families, this is the encouraging part: classification is not fixed, and good conduct generally moves a person toward less restrictive settings.

County jail classification is simpler and local

Before a person reaches the state system, and for people serving shorter sentences, Montana county jails run their own classification. Each county jail does its own intake and assigns housing based on the charge, criminal history, behavior, and safety, separating people by risk and providing protective or medical housing as needed. County jails also hold people awaiting trial, people serving short local sentences, and people who have been sentenced to state custody but are waiting to be transferred to or assessed by the Department of Corrections, and one regional prison in the state holds both county jail offenders and state inmates. Because each county runs its own jail, the rules, housing, and privileges vary from one county to the next. For families, the main thing to know is that county jail classification is a separate, local process, and the state prison classification described above only begins once a sentenced person is committed to the Department of Corrections.

How federal classification works

Federal classification, run by the Bureau of Prisons, uses a structured, points based system that applies the same way nationwide. At intake, the Bureau scores each person on factors like the severity of the offense, criminal history, any history of violence or escape, and the length of the sentence, and that score places them in one of several security levels, from minimum security camps, to low and medium security institutions, to high security penitentiaries, plus administrative facilities for special needs such as medical care or pretrial detention. The Bureau then designates the person to a specific facility, ideally within 500 miles of home, though the actual placement depends on bed space, security level, and program or medical needs, so a person may be sent far from home. Custody is reviewed over time, and good conduct and program participation can lower a person's security level and open the door to a transfer to a less restrictive facility. The biggest practical difference from the state system is that the rules are uniform nationwide and a person can be designated anywhere in the country, so families with a federal case should be prepared for placement that may have little to do with where they live.

The bottom line

Classification is what decides where your person lands in Montana, which assesses each new commitment, runs men through the diagnostic intake unit at the state prison in Deer Lodge, and assigns a custody level from minimum to maximum, with placement spread across the state prison, pre release centers, regional facilities, and contracted prisons. Montana has a death row but has not carried out an execution in many years. A person does not choose their facility and, in a large rural state with few facilities, can be held many hours from home, but steady good conduct lowers the custody level over time and opens the door to lower security and pre release. County jails run a simpler, local classification, and federal classification uses a uniform, points based national system. The most useful things a family can do are wait for the permanent placement after assessment and intake, learn the person's custody level and what it allows, and understand that classification is reviewed and can change. This is general information about how classification works and not legal advice, and because policies change, the department, the Bureau of Prisons, or the specific facility is the right source for current specifics.
