Detention Center 1 Overview
Cameron County Detention Center 1 is listed by the Cameron County Sheriff's Office contact page as a separate jail contact at 1145 E. Harrison St., Brownsville, TX 78520, with phone number (956) 544-0836. The operator is the Cameron County Sheriff's Office. The researched county material does not publish a separate public Detention Center 1 page with independent housing descriptions, visitation hours, pod details, or capacity figures.
Because the county treats Detention Center 1 as part of the broader county jail system, the same roster, visitation, mail, commissary, medical, and phone rules should be used unless facility staff gives a more specific instruction. That matters for anyone checking custody after a new arrest. A roster entry can confirm that a person is in the Cameron County jail system, but the public table fields captured in research were Picture, BookingDt, Defendant, BookingNumber, SONumber, and Charges. No public building column was captured.
Detention Center 1 should not be confused with the court record offices near the same Brownsville civic area. Jail custody is handled by the sheriff. Court records after a jail arrest may later move through the District Clerk, County Clerk, or Tyler Smart Search depending on the court and case type. The jail roster gives the arrest-side booking record, while the court system answers whether a charge has been filed, set for hearing, amended, or dismissed.
The official sheriff contact table is the source that separates Detention Center 1 from other Cameron County jail contacts. The image below comes from the county Sheriff's Office contact information page.
Use that source when the question is where to call, and use the roster when the question is whether a person appears in county jail custody.
Detention Center 1 Population
Official sources found for this project do not give a Detention Center 1 bed count, housing count, or average daily population. The Texas Commission on Jail Standards reports Cameron County as a county jail system with countywide capacity. The June 1, 2026 TCJS current population workbook lists Cameron County at 1,746 beds and 1,514 total jail inmates, equal to 86.7 percent of countywide capacity. Those numbers should not be read as a Detention Center 1 building count.
The lack of a building-specific population number affects how a Detention Center 1 inmate lookup should be handled. The TCJS report explains the scale of Cameron County jail custody, and the sheriff roster identifies current and recent people housed in the county jails. Neither source replaces a direct call to (956) 544-0836 when a visitor needs to know whether the person is in Detention Center 1 or has been moved within the jail system.
Detention Center 1 Lookup
Start with the Cameron County Inmates List. The county says users can type in the search box to instantly filter the list. The direct roster shows booking photos, booking dates, defendant names, booking numbers, SO numbers, and charges. It also states that the roster is updated every two hours. Those are strong public lookup features, but they are not a substitute for facility confirmation.
The county roster scope is narrow in an important way. Cameron County says the roster is not a comprehensive listing of all inmates being held and that it does not include federal prisoners or detainees. A person held for ICE, BOP, U.S. Marshals, or after state-prison transfer may need a different locator. For state sentenced custody, use the Texas Department of Criminal Justice search. For immigration custody, use ICE ODLS. For county custody at Detention Center 1, follow the roster with a facility call.
- Open the county inmate-list page and read the scope notice before searching.
- Search by defendant name first, then try booking number or SO number if known.
- Review BookingDt and Charges as booking information, not proof of guilt.
- Call Detention Center 1 at (956) 544-0836 to confirm the building and visit route.
- If the roster is blank, check TDCJ, BOP, ICE, VINELink, or the county public-records request channel depending on the custody issue.
| Roster Field | How It Helps | Detention Center 1 Limit |
|---|---|---|
| Picture | Helps compare identity | Does not prove current building |
| BookingDt | Shows recent booking timing | Not a housing assignment |
| BookingNumber | Useful for jail calls and records requests | Format details not published |
| SONumber | Useful sheriff identifier | Still needs staff confirmation |
| Charges | Shows arrest-side reference charges | Court charges may later change |
Detention Center 1 Contact
Use the Detention Center 1 phone number for building-specific questions. If the issue is a court case, filed charge, or hearing date, move from the jail roster to the court record channels. If the issue is a public record that is not visible online, Cameron County uses NextRequest as a countywide public-records intake route, while prosecutor and court records use different offices.

Detention Center 1 Visits
Detention Center 1 uses the countywide visitation rules found in Cameron County jail sources unless staff provides a different instruction. Adult visitors need valid photo ID. Visitors must be on the inmate's visitation list, although a shift supervisor may approve a visit when no list is in the system. Visitors must sign in 20 minutes before visitation begins and no more than one hour before the visit begins.
The county rules are strict about clothing and items. No purses, wallets, bags, phones, electronics, recording devices, writing instruments, lighters, weapons, liquids, or food may be taken into the visitation lobby or area. Clothing cannot be revealing, backless, strapless, low cut, wide neck, transparent, or marked with obscene, offensive, or gang-related language or drawings. Shorts, skirts, and dresses must be at least two inches under the knee in a normal standing position.
| Topic | County Rule | Before Visiting Detention Center 1 |
|---|---|---|
| Adult ID | Valid photo ID required | Bring ID that matches the visitor list |
| Arrival | Sign in 20 minutes early | Call for the correct entry point |
| Late arrival | Late visitors are not permitted | Leave time for downtown parking |
| Visitor list | Name must be on the inmate list unless approved | Confirm before traveling |
| Rule violations | Visits can be cancelled for up to 30 days or longer | Follow staff orders at sign-in |
The visitor rules image is taken from the official Cameron County Rules of Visitation page.
The same rules are the best researched source for Detention Center 1 because no separate public Detention Center 1 visit page was located.
Detention Center 1 Mail
Countywide mail and money rules apply to Detention Center 1 unless staff says otherwise. Incoming mail is inspected. Greeting cards larger than 5 by 7 inches are returned, internet printouts are returned, and inmates may possess up to three pictures at one time. Pictures cannot contain nudity or sexually explicit material. Books and subscriptions must come directly from a publisher or bookstore and must be soft backed.
Money orders and certified checks for inmate trust funds are mailed to the Cameron County Jail Division trust fund address in Olmito. The payment must be made payable to the inmate and include the inmate name and inmate ID number. Cash is not accepted by mail. Trust-fund balances are returned at release or transfer, and transfers between inmates are not allowed under the researched jail rules.

Detention Center 1 Booking
County jail booking and classification happen inside the sheriff jail system, and the public source does not isolate that process by Detention Center 1. The important public markers are the roster fields and the phone access rule. Once booking is complete, inmates receive telephone access, and private-use phones are available in housing areas. That timing can matter when family members are waiting for a call after arrest.
The roster is not the end of the court process. A booking charge may be a starting allegation or arrest-side reference. Magistrate review, bail decisions, prosecutor screening, and clerk filings can change what appears later in court records. Use Cameron County Court Records After Jail Arrest when the question shifts from custody location to filed charges or hearings.
Note: Call Detention Center 1 before a visit because the public roster does not show the building assignment.
About Detention Center 1
Detention Center 1 is one of the official Cameron County jail contact points on Harrison Street. Its public footprint is smaller than the countywide jail pages, so accurate use depends on separating what is known from what is not published. The address and phone are published. The countywide custody role is clear. Separate bed count, program details, and housing-unit assignments were not located in official public sources.
For practical use, the Detention Center 1 sequence is simple: search the county roster, save the booking number or SO number, call the facility, then use the records or court channel only if the question moves beyond current custody. That sequence protects against a common mistake in Cameron County searches, where a person may be in the jail system but not at the building a visitor first assumes.
