Boulder County Inmate Population Overview
The Boulder County inmate population is anchored by the Boulder County Jail, the secure county facility operated by the Boulder County Sheriff's Office. Local jail custody includes adults booked after arrest, people held on Boulder County warrants, pretrial detainees waiting for court action, and people serving local jail sentences. The public jail report is not a static roster. Boulder County uses an embedded Power BI reporting tool with Search Inmates, Bookings, Listing Report, Releases, Historical Statistics, and Jail Population tabs.
Local custody is broader than the jail alone. Boulder County also uses the Joe Pelle Center for alternative sentencing, Work Release, Day Reporting, Electronic Home Monitoring, and Community Corrections. ICCS-Boulder and Longmont Community Treatment Center are contracted residential community-corrections facilities. Those programs are not searched like standard jail housing. Sentenced state prisoners move into Colorado Department of Corrections custody, and no CDOC prison was identified inside Boulder County in the official facility lists reviewed.
Boulder County Inmate Population Statistics
Recent Boulder County inmate population figures should be read as averages and trend measures unless the county's live report is checked directly. The official jail history page gives the bed count, while the Vera Institute county dataset supplies recent average jail population values for Boulder County. Those sources point to a jail that has held hundreds of people on an average day while remaining below its official rated capacity in the recent captured data.
| Measure | Figure | Source / Year |
|---|---|---|
| Boulder County Jail current rated capacity | 543 beds | Boulder County Jail History page, accessed 2026 |
| Jail opening date | January 1988 | Boulder County Jail History page |
| Original jail design capacity | 287 beds | Boulder County Jail History page |
| Average jail population | 358 | Vera Institute county dataset, 2024 |
| Average jail population | 323 | Vera Institute county dataset, 2025 |
| 2025 capacity use | About 59.5% | Computed from 323 average population and 543-bed capacity |
Boulder County Jail Population Trends
The Vera trend line shows the Boulder County jail average rising from 2021 through 2024, then dropping in 2025. The 2024 value of 358 was the highest recent Vera value captured in the research file. The 2025 value of 323 is lower than 2024 and is also below the official 543-bed capacity. That does not mean day-to-day custody is simple. A jail average can sit below capacity while individual booking, bond, court, medical, classification, or transport issues still affect people in custody.
The county's own reporting changed in 2024. A Boulder County Sheriff's Office announcement said the enhanced daily booking and listing reports added fields such as sex or gender, sentencing status, ethnicity, race, arresting agency, length of stay, and historical jail statistics. That makes the local jail report an important inmate-population source even when live dashboard values must be checked in the report itself.
The Colorado state HB19-1297 jail data dashboard is another official way to review county jail measures by time and county.
The state dashboard is useful for jail-population context, but the Boulder County Power BI report remains the local route for current jail listing, booking, release, and population tabs.
| Year | Average Jail Population | Rated Capacity | Jail Population Rate |
|---|---|---|---|
| 2021 | 311.25 | 543 | 136.6 |
| 2022 | 328.75 | 543 | 144.29 |
| 2023 | 329.75 | 543 | 145.24 |
| 2024 | 358 | 543 | 157.68 |
| 2025 | 323 | 543 | Not populated in captured row |
Boulder County Inmate Population Makeup
The captured Vera dataset fields show most Boulder County jail custody as pretrial in 2024. The 2024 row lists a total jail population of 358, a pretrial field of 348.75, and a sentenced field of 37. The 2025 row lists a total of 323, a pretrial field of 279, and a sentenced field of 88. Those fields should be read with care because dataset categories may overlap, round, or use definitions that do not add cleanly.
- Sex fields: Vera's 2025 row lists 270 male and 51.5 female in the captured Boulder County fields.
- Race and ethnicity fields: Captured 2025 fields include Black, Latinx, and White values, but categories should not be forced to total exactly.
- Custody status: The county report and Vera data both support a distinction between pretrial and sentenced jail custody.
- Other systems: State prison, federal, and ICE custody are searched outside the Boulder County jail report.
Note: Treat Vera values as trend data, not as a live head count for a person currently held at the jail.
Boulder County Jail Capacity
The Boulder County Jail opened in January 1988 with an original 287-bed design capacity. The official jail history source gives the current capacity as 543 beds. Recent Vera averages of 358 in 2024 and 323 in 2025 are below that rated capacity, so the captured data does not support a claim that the jail was overcrowded in those average-year figures. It also should not be read as proof that every day, unit, or custody class has spare space.
The official jail page identifies the facility and links jail programs and related custody resources.
The official facility source supports the jail's role as the secure local custody center, while population averages and historical statistics must be read from the reporting sources.
Boulder County Inmate Record Laws
Colorado law separates general public records, criminal justice records, court records, and sealed records. Current jail listing data is published through the sheriff's jail report. Older bookings, case reports, mugshots, body-worn-camera footage, and sheriff-held records route to the Sheriff's Records Division and the official records portal. Formal charges and court files route to Boulder County Combined Court and the Colorado Judicial Branch.
Key Statutes:
C.R.S. § 24-72-201 et seq. sets Colorado's general public-records inspection framework under CORA.
C.R.S. § 24-72-301 et seq. governs criminal justice records held by law-enforcement, jail, sheriff, and prosecutorial agencies.
C.R.S. § 24-72-305 and § 24-72-305.5 address criminal justice record access, denial authority, and booking photographs.
C.R.S. § 2-3-1901 and § 2-3-1901.5 create Colorado jail-standards oversight, with statewide compliance rules beginning July 1, 2026.
Boulder County and State Prison Custody
The Boulder County inmate population in the county jail report does not become the state prison population unless a person is sentenced and transferred into Colorado Department of Corrections custody. The CDOC Offender Search is the correct statewide lookup for sentenced state prisoners. CDOC search fields include DOCNO, last name, first name, gender, and CAPTCHA when the public page requires it.
No Colorado DOC prison was identified inside Boulder County from the official CDOC facilities list reviewed. A Boulder County case can still lead to CDOC custody after conviction and sentencing. Once transfer occurs, county jail visitation, mail, and deposit rules stop being the right instructions. CDOC uses its own visitor approval, inmate mail, phone, and money processes.
Search Boulder County Inmates
The official Boulder County inmate search begins at the county's Listing and Booking Reports page. The embedded report is the county's public channel for current inmates, bookings, listing records, releases, historical statistics, and jail population views. If the embedded frame does not load, the direct Power BI report URL in the county page is the next official route.
The county report is better described as a set of reports than a single roster page. The Search Inmates tab is the direct current-custody path. The Listing Report tab has wider fields, including inmate number, booked date, physical description fields, charges, arresting agency, court date, scheduled end date, bond amount, and pay-bond display. The Bookings and Releases tabs help when a person was recently booked or has left custody.
- Open the official Boulder County Listing and Booking Reports page.
- Use the Search Inmates tab for someone currently lodged in the Boulder County Jail.
- Type any part of the person's name in the Search Name field and select the matching name from the list.
- Use Listing Report, Bookings, or Releases when a booking number, release date, court date, or broader field set is needed.
- Sort by column headings, use Reset Page to clear report filters, and check spelling variations if no result appears.
- Call the Records Division or jail line for older bookings or records not displayed online.
Boulder County Roster Search Fields
The jail report's search controls are specific to the Power BI interface. A user does not open a profile page in the way many county roster sites work. The person types part of a name, selects a matching name from the list, and reads the table fields that appear in the report. The public report text says the data is informational and may contain inaccuracies or omissions.
The county report landing page is the source for the current jail reporting tool.
The screenshot shows why Boulder County lookup instructions should mention report tabs, not just a last-name box.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Search Name | Power BI slicer/search list | Unspecified | Type any part of a name, then select the matching name from the list. |
| Page navigation | Tab/page buttons | Optional | Search Inmates, Bookings, Listing Report, Releases, Historical Statistics, Jail Population. |
| Reset Page | Button | Optional | Clears or resets report page state. |
| Column headings | Sortable table headers | Optional | Select a heading to change sort order between ascending and descending. |
Boulder County Inmate Record Fields
Boulder County's public jail report is a table-entry system. It did not show a separate public inmate profile URL, a mugshot field, or a public housing-unit field in the inspected inventory. Its strengths are booking data, release data, charges, arresting agency, bond amount, court date, demographic fields, and historical population reporting. Booking # and Inmate Number appear in different tabs, so they should not be treated as the same identifier unless the county states that.
| Field | What It Shows |
|---|---|
| Name | Inmate or booked person's name in report tables. |
| Admission date | Current inmate admission date on the Search Inmates view. |
| Booking # | Booking identifier on Bookings and Releases views. |
| Inmate Number | Identifier shown on the Listing Report. |
| Charges / Offense | Booking or listed charge field, not always the final court-filed charge. |
| Court Date | Scheduled court date on the Listing Report when available. |
| Bond Amount | Bond amount tied to the booking or custody entry where shown. |
| Release Date / Resolved Reason | Release or resolution fields shown in release and booking views. |
Older Boulder County Inmate Records
A current-inmate search can fail because the person bonded out, was released, was transferred, is listed under a different spelling, or is outside Boulder County custody. The official fallback is not a commercial inmate-search site. Boulder County's report text routes older jail bookings to the Sheriff's Records Division at 303-441-3600. Requests for case reports, mugshots, or body-worn-camera footage go through the Sheriff's Records Request portal.
VINELink Colorado is available as a custody-status notification channel. It does not replace the jail report, CDOC search, BOP locator, ICE ODLS, or court docket search. It is most useful when a person wants notification about custody status changes after identifying the right custody system.
Boulder County Jail vs DOC Search
The county jail report covers local custody and recent jail reporting. The state prison locator covers sentenced state prisoners after CDOC admission. Federal and immigration custody use separate systems. This distinction matters in Boulder County because the local facility map does not include a state prison, BOP prison, or ICE detention center inside the county.
| Question | Boulder County Jail Report | CDOC Offender Search |
|---|---|---|
| Who is covered? | People in or recently reported through Boulder County jail custody and release reports. | Sentenced state prisoners in Colorado DOC custody. |
| Search fields | Search Name slicer and report tabs. | DOCNO, last name, first name, gender, CAPTCHA. |
| Booking data | Booking #, booked date, arresting agency, charge, bond, and release fields. | Not a county booking report. |
| Visitation | Remote video visitation through HomeWAV for the county jail. | CDOC visitor application and facility-specific approval. |
| Money | JailATM for county jail commissary deposits. | JPay or Western Union through CDOC's Inmate Bank process. |
State Federal and ICE Searches
Federal custody is separate from Boulder County jail custody. The BOP Inmate Locator covers federal inmates incarcerated from 1982 to the present and returns fields such as name, register number, age, race, sex, release date, and location. Federal pretrial custody can involve the U.S. Marshals Service, which does not provide the same kind of general public detainee locator as BOP.
Immigration detention uses ICE ODLS. No ICE detention facility was identified in Boulder County. The nearest official ICE detention facility found in the research was the Denver Contract Detention Facility in Aurora. ICE ODLS is for immigration custody, not Boulder County criminal charges, jail bond, or local court dates.
- Pretrial detainee
- A person held before case disposition or sentencing.
- Sentenced inmate
- A person serving a sentence after conviction.
- Detainer
- A hold or notice from another agency that may affect release.
- Community corrections
- Residential or non-residential supervision used as prison diversion or prison-to-community transition.
Boulder County Detention Facilities
Boulder County has one primary secure jail and three local community-custody or community-corrections facilities in the facility map. The jail is searched through the county report. The Joe Pelle Center, ICCS-Boulder, and Longmont Community Treatment Center are tied to alternative sentencing, work release, residential community corrections, and transition programs rather than a normal public jail roster.
- Boulder County Jail holds adults in secure county custody after arrest, on warrants, before court, and on local jail sentences.
- Joe Pelle Center serves Community Corrections, Work Release, Day Reporting, and Electronic Home Monitoring clients.
- ICCS-Boulder is a contracted residential community-corrections halfway house serving adults with felony cases or transition placements.
- Longmont Community Treatment Center is a Longmont residential community-corrections facility operated under county contract.
Boulder County Bond and Release
Bond affects the Boulder County inmate population because many people are held only until bond, release conditions, or a court order changes. The jail FAQ says newly arrested inmates who have not bonded usually see a judge within 48 hours of arriving at the jail, not counting weekends and holidays. The DA's county-court materials explain that a Bond Commissioner reviews cases after arrest where allowed, and some cases, including domestic-violence arrests, may wait for judge review before bond is set.
Cash bonds can be posted at the Boulder County Jail at any time by cash, credit card, or cashier's check. Personal checks are not accepted. A hold, warrant, federal issue, immigration matter, or another agency's detainer may keep a person in custody even when a local bond question appears resolved.
Boulder County Jail Programs
The jail programs page lists educational, recreational, religious, substance-abuse, mental-health-related, and volunteer-led services. Availability can depend on custody status, staffing, classification, and current facility rules. The Joe Pelle Center adds a distinct local alternative-sentencing layer by supporting Work Release, Day Reporting, Electronic Home Monitoring, and Community Corrections rather than only secure jail housing.
The county's Joe Pelle Center page describes the alternative-sentencing facility and its program role.
That facility is part of the local custody picture, but it should not be confused with the secure jail roster.
Boulder County Inmate Population FAQ
How big is the Boulder County inmate population?
The captured Vera dataset lists a 2025 average jail population of 323 and a 2024 average of 358. Those are average trend figures, not a live count. The live local picture should be checked in the Boulder County jail report's current and population tabs.
How do I search Boulder County inmates?
Use the county's Listing and Booking Reports page. The Search Inmates tab is for current Boulder County Jail custody. The Bookings, Listing Report, and Releases tabs provide other fields that may help when the person is no longer in current custody.
Does the Boulder County roster show mugshots?
The inspected public report fields did not show a mugshot or booking-photo field. Boulder County report text routes mugshot, case report, and body-worn camera requests to the Sheriff's Records Request portal.
Where do sentenced state prisoners appear?
Sentenced state prisoners are searched through Colorado DOC Offender Search after they enter CDOC custody. The Boulder County jail report is not the ongoing state prison locator.
Is there a Boulder County Sheriff inmate-search app?
No official Boulder County Sheriff inmate-search app was confirmed from official pages in the research pass. Use the official web report, jail phone line, Records Division, and state or federal locators instead.
