About the Jefferson County Detention Center

The 24-bed Jefferson County Detention Center is responsible for the housing and care of those who are accused or convicted of committing a misdemeanor or felony in Jefferson County as they wait for their trial or as they serve their sentence, usually less than one year. 

It serves many law enforcement organizations including the Sheriff’s Department, local police, Immigration, and other surrounding counties as needed.

If you have questions regarding an inmate or the programs and services provided, the staff can be reached at 406-225-4091, and an online listing of all the detainees is published for your own investigation.

Upon intake, the booking process is completed, which includes a medical screening, fingerprinting and mugshots, DNA sample, along with an assessment to determine security needs, medical needs, mental health requirements, and housing assignment. 

Staff is available to transport all inmates to court dates and any medical appointments or emergency needs, as well as inspecting all mail for contraband, receiving commissary funds and other money for inmates, maintaining the safety of the community and the security of the facility, and other tasks. 

The Jefferson County Detention Center also provides several other services to inmates including basic needs in meals, laundry, and hygiene items, and programs including AA, counseling, religious programs, education, recreation, and opportunities to grow social and life skills. 

Along with the efforts made by the staff, reduced recidivism is seen when inmates are able to stay in contact and supported by their family or friends who are not incarcerated so mail, phones, and visits are provided. 

Visits are in person, and are via video and an account is created online to book and complete visits, allowing both visitors and inmates to schedule a visit. 

Phone accounts are also registered online, and allow for inmates to make outgoing calls during the daytime and evening hours when they are not participating in a task or program. 

Information for money for an inmate’s commissary can be found on our Inmate Money page. 

All personal mail is sent to: 

Inmate's Full Name & Inmate ID #

Inmate Bail and Bonding

How to pay bail in Jefferson County for an arrestee

Once an individual is booked at Jefferson County Detention Center in Boulder, options for their release include:

1. Release without paying bail, with a commitment to appear in court.
2. Continued detention until their court date.
3. Release upon paying a bail or bond. Call 406-225-4091 for the bail amount.

Bail can be paid through various methods.

  • Bring the full cash bond to the jail's bonding window or the clerk of court and pay by cash, cashier's check or money order; many jails also take debit or credit cards for a fee through a lobby kiosk or an online bond vendor, and staff will need the inmate's full name and booking number (jail: 406-225-4091).
  • A licensed bail bondsman in Jefferson County can assist with the process.
  • An owner can often pledge land or a home as bond collateral by proving clear title and equity worth at least the bond, frequently double the bond, with a deed and a recent tax or appraisal value; the court that set bail must approve the property before release.
