The Williamson County Inmate Population
The Williamson County inmate population is centered on the Williamson County Jail in Georgetown, which is run by the Williamson County Sheriff's Office Corrections Bureau. The jail holds pretrial detainees, local misdemeanor inmates, county jail sentences, parole violators, state jail felony cases awaiting action, and other local holds. State and federal systems add separate layers. Bartlett Unit is a Texas Department of Criminal Justice prison inside Williamson County, T. Don Hutto Detention Center is an ICE civil immigration facility in Taylor, and Central Texas Treatment Center is a residential community-corrections program in Granger.
The county jail count rises or falls when arrests increase, bond decisions change, cases move through court, people are released, and sentenced inmates transfer to TDCJ. The Texas Commission on Jail Standards reports jail population and capacity data for the county jail. The official Corrections Bureau page also gives local operating details, including jail capacity, approximate daily population, booking and release duties, bonds, visitation, mail, inmate money, and commissary services.
Williamson County Inmate Population Statistics
The strongest current figures come from the Texas Commission on Jail Standards population reports and the official Williamson County Corrections Bureau page. TCJS reported 649 people in the Williamson County Jail on June 1, 2026. The same state workbook listed 1,104 rated beds, which placed the jail at 58.786 percent of capacity. A separate TCJS incarceration-rate workbook used an average daily population of 666 and a county population base of 727,480 for June 2026.

Those workbooks are the source to check when comparing a local jail count with rated capacity or statewide jail reporting categories.
Williamson County Inmate Population Trends
The current TCJS workbook extract shows the Williamson County inmate population moving upward after 2023, then easing slightly in the first half of 2026. The average monthly total was 586 across four available 2022 rows and 582 across twelve 2023 rows. It rose to 594 in 2024 and 664 in 2025. Through the first six reported 2026 rows, the average was 644. The research did not locate a current county consent decree, overcrowding order, or new jail construction plan tied to those counts.
| Year | Average Reported Monthly Jail Population | Notes |
|---|---|---|
| 2022 | 586 | Four available monthly Williamson rows, range 567 to 615 |
| 2023 | 582 | Twelve rows, range 544 to 617 |
| 2024 | 594 | Twelve rows, range 522 to 665 |
| 2025 | 664 | Twelve rows, range 603 to 726 |
| 2026 | 644 | First six reported rows through June 1, 2026, range 620 to 665 |
Who Makes Up the Williamson County Inmate Population
The June 1, 2026 TCJS classification row shows that felony pretrial custody is the largest published category in the Williamson County inmate population. TCJS counted 349 local pretrial felons, 74 pretrial Class A/B misdemeanants, 68 pretrial state jail felons, 61 convicted felons or parole violators sentenced to TDCJ divisions, and 31 parole violators with a new charge. The same row also counted 19 convicted misdemeanants, 13 convicted state jail felons sentenced to state jail time, seven pretrial Class C misdemeanants, seven convicted felons sentenced to county jail time, six parole violators or blue warrants, one bench warrant, and ten others.
- Pretrial felony custody was the largest single category, with 349 people in the TCJS June 2026 row.
- Pretrial misdemeanors included Class C and Class A/B groups, which TCJS reports separately.
- State-transfer categories included TDCJ-sentenced felons, state jail felons, parole violators, and blue-warrant holds.
- Other custody groups can reflect court, agency, or classification details that do not fit the main categories.
Williamson County Jail Capacity
Williamson County was well below rated jail capacity in the June 2026 TCJS data. The official Corrections Bureau page says the direct-supervision expansion opened in late 2003 and gave the jail bed space for 1,104 inmates. TCJS used the same rated capacity in the June 1, 2026 workbook. With 649 people in jail on that date, the county was below 60 percent of rated capacity. That number does not mean no housing, medical, staffing, or classification pressure exists inside the jail. It does mean the sourced countywide jail-population data did not show overcrowding by bed count on that date.
The Williamson County Corrections Bureau page also documents the local jail functions behind the count.
That county page is the practical source for jail capacity, visitation, mail, deposits, commissary, and the jail information phone line.
Laws Governing Williamson County Inmates
Texas law controls how jail records, arrest information, capacity reporting, bail, and post-arrest court steps work. The Texas Public Information Act governs requests to Texas government bodies. Government Code 552.108 can protect some law-enforcement and prosecution material, but subsection 552.108(c) says the law-enforcement exception does not remove basic information about an arrested person, an arrest, or a crime. That distinction matters when a full file is withheld but basic booking information may still be available.
Key Statutes:
Texas Government Code Chapter 511 creates the Texas Commission on Jail Standards, the agency behind jail standards and population reporting.
Texas Local Government Code Chapter 351 covers county jail authority and the sheriff's jail-custody duties.
Texas Code of Criminal Procedure Article 15.17 requires prompt magistrate warnings after arrest and affects early bond decisions.
Texas Code of Criminal Procedure Chapter 49 includes death-investigation provisions relevant to deaths in custody.
Williamson County State Prison Population
State-prison custody is not part of the county jail roster, even when the prison is physically in Williamson County. Bartlett Unit is a TDCJ prison in Bartlett with a listed capacity of 1,049 and male G1-G2, transient, and restrictive-housing custody levels. A person sentenced from a Williamson County case may be assigned to Bartlett or to another TDCJ unit after intake, classification, bed-space review, health needs, security level, and program needs. The correct tool for that custody stage is the TDCJ Inmate Search, not the county jail lookup.
How to Search Williamson County Inmates
The official local route begins at the county's Court Case Lookup page, which links to criminal case records, civil and probate records, and Jail Lookup. Use Jail Lookup for current county custody. Use the criminal case portal when the question is about charges filed in court after booking. The jail lookup runs through an ASP.NET PublicAccess system, so a browser may need to accept terms or create a session before the search form loads.
The direct county-linked jail lookup page is shown in the official jail lookup portal screenshot below.
The portal is the first place to check for a local booking before moving to state, federal, or immigration locators.
- Open the county Court Case Lookup page and choose Jail Lookup for current custody.
- Search by the most exact name or identifier available, including a booking or case number if known.
- Try spelling variants, because county record systems may index names differently from police paperwork.
- Call the jail information line if a new arrest does not appear after booking or magistration delay.
- Use TDCJ, BOP, or ICE if the person is no longer in county jail custody.
Current Williamson County Inmate Lookup
The Williamson County jail lookup is best for people currently booked into the county jail after arrest by a sheriff's deputy, city police officer, state trooper, or other local agency. The research did not expose a stable full field list from command-line inspection because the portal redirected through session pages. The safest search approach is to start with full legal name, then add a booking number or case number if the family, attorney, bond paperwork, or court notice has one.
| Field Label | Type | Required | Notes |
|---|---|---|---|
| Search category / Jail Lookup | Portal mode | Yes | County page links to Jail Lookup from Court Case Lookup. |
| Name fields | Text | Unspecified | Use full legal name and spelling variants. |
| Booking or jail identifiers | Text | Unspecified | Use exact booking or case numbers when known. |
| Search / Submit | Button | Unspecified | Button label was not reliably captured due session redirects. |
Past Williamson County Inmate Records
A released person may no longer appear in the jail lookup. The research did not locate an official separate daily booking report or archive for old Williamson County jail bookings. For historical booking records, use a written request to the office that maintains the record and include the person's full name, date of birth if lawful to provide, booking date, arresting agency, case number, and the exact record sought. The county public-information page says requests must be in writing and can be routed by approved hand-delivery, mail, or email channels for the County Attorney process.
What a Williamson County Inmate Record Shows
The public sample profile fields were not fully confirmed during research, so no page should promise every Williamson County inmate record displays a mugshot, housing unit, bond, or court date. The underlying jail process does support basic booking, charge, bond, property, money, court movement, visitation, mail, and release functions. The criminal case portal is separate and should be used for filed charges after prosecutor review.
| Field | What It May Show | Research Status |
|---|---|---|
| Name | Person booked or held | Official lookup exists |
| Booking number | Jail booking identifier | Not confirmed from public sample |
| Charges | Booking allegations, holds, or warrants | Confirm through portal result |
| Bond | Bond amount or hold status | Jail processes bonds, display not confirmed |
| Mugshot | Booking photo if the portal displays it | Not confirmed |
| Release/status | In custody, released, transferred, or other status | Exact values not confirmed |
County Jail vs State Prison
Many Williamson County inmate population searches fail because the wrong custody system is used. The county jail lookup covers local jail custody after arrest and for short local sentences. TDCJ covers sentenced state-prison custody after the person has moved into the state system. BOP covers many sentenced federal prisoners from 1982 to present. ICE ODLS covers immigration detainees, including detainees at T. Don Hutto when they are in ICE civil custody.
| Custody Type | Where to Look | What It Covers |
|---|---|---|
| County jail | Williamson County Jail Lookup | Recent arrests, pretrial detainees, local jail sentences, holds |
| State prison | Texas Department of Criminal Justice locator | Sentenced state prisoners after transfer and classification |
| Federal prison | Federal BOP inmate locator | Federal prisoners, mainly sentenced custody from 1982 forward |
| Immigration detention | ICE Online Detainee Locator System | ICE civil detention by A-number or biographical search |
State and Federal Search
Use the TDCJ Inmate Search for a sentenced Texas prisoner. It accepts name, TDCJ number, or SID number. Use the Federal Bureau of Prisons inmate locator for many federal prisoners, but do not expect it to list every federal pretrial hold. Use ICE ODLS for immigration custody, either by A-number and country of birth or by biographical details. VINELink can help with custody notifications, but it does not replace the official roster or locator of record.
Williamson County Detention Facilities
The Williamson County inmate population is spread across different custody systems, so the facility name matters before any search begins. The county jail is the primary local booking site. Bartlett is a state-prison unit. T. Don Hutto is ICE civil immigration detention. Central Texas Treatment Center is a residential treatment and community-supervision placement, not an ordinary jail roster facility.
- Williamson County Jail holds local pretrial detainees, local sentences, bonds, releases, and other county jail custody.
- Bartlett Unit houses male sentenced TDCJ prisoners and is searched through the state locator.
- T. Don Hutto Detention Center holds ICE civil immigration detainees and is searched through ICE ODLS.
- Central Texas Treatment Center serves court-ordered treatment participants under community supervision.
Williamson County Custody Terms
Several record terms mean different things in jail, court, and prison systems. These definitions help separate booking status from court status and state custody.
- Booking
- Jail intake after arrest, including identification, property, fingerprints, photo, charge entry, and screening.
- Magistration
- The early Article 15.17 appearance where warnings, counsel rights, and bail matters are addressed.
- Detainer
- A hold request from another agency that may block release even after local bond is posted.
- Blue warrant
- A Texas parole violation warrant that can keep a person in custody.
- Expunction
- A Chapter 55 court process that can destroy or return qualifying criminal records.
