Byrd Unit

TDCJ's male diagnostic intake unit in Huntsville, where men entering Texas prison custody are received, classified, and assigned a unit.

Overview

The Byrd Unit — officially the James “Jay” H. Byrd Unit — is TDCJ’s designated Diagnostic Intake Facility for men. TDCJ describes intake as the stage where people are photographed, iris scanned, and fingerprinted; given physical, dental, and eye examinations; tested for medical, mental health, and educational needs; and interviewed about their history. The results drive the classification decision that determines custody level and the unit where the person will actually serve their sentence.

TDCJ’s handbook describes intake as taking “the first few weeks.” Because stays are short, the unit page lists no educational programs and no community work projects — Byrd is a processing stop, not a destination. The State Classification Committee assigns the first unit, and people do not choose where they are sent.

What Makes Byrd Unit Different

• It is the front door of the Texas prison system for men: a designated Diagnostic Intake Facility where newly sentenced people are received and classified before transfer.
• Visiting is restricted during intake by statewide policy — the rules below are the page’s most important content for families of someone who just entered TDCJ custody.
• TDCJ does not notify families of the unit assignment or a transfer. Policy makes the incarcerated person responsible for telling the people on their visitor list, and families can check the assigned unit themselves through the TDCJ inmate locator or the information line at (936) 295-6371 or (800) 535-0283, Monday-Friday 8 a.m.-5 p.m.
• It sits inside Huntsville’s cluster of prisons — TDCJ lists seven units in the city of Huntsville alone, and Byrd is about two road miles from the Huntsville “Walls” Unit, so confirming the exact unit matters.
• The unit also hosts TDCJ’s Central Region offender transportation operation, established on a site dating to 1964.

Visiting Hours and Procedures

TDCJ’s statewide visitation policy (I-218) sets specific rules for people in intake, and they control what is possible at Byrd.

TDCJ’s family guide also excludes people in intake from the standard one-visit-per-week entitlement, and TDCJ does not publish how long visitor-list processing typically takes. Whether a family gets a general visit before the person transfers depends on that processing — which is why calling the unit first matters. Statewide rules — approval, ID, prohibited items, and dress code — are covered by the card above and in Visiting in Texas.

A phone number must be on the person’s approved contact list before calls can connect, and that approval also takes time during intake. Calls are placed by the incarcerated person on TDCJ’s Securus phone system; account setup and rates are covered in Phone & Video Calls.

Getting There and Parking

Byrd is on FM 247 just north of downtown Huntsville, with the I-45 corridor as the main approach from every direction.

TDCJ does not publish visitor parking details for the unit. There is no fixed-route bus service in Huntsville; Brazos Transit District operates shared-ride, advance-reservation service covering Walker County.

Nearby Services

Huntsville’s services cluster along I-45, including chain hotels (Best Western, Holiday Inn Express & Suites, Hampton Inn & Suites, Fairfield Inn & Suites). Hospitality House, at 912 10th Street, is a donation-based guest house specifically for families of people incarcerated in the Texas prison system — it accepts guests Thursday through Saturday nights, allots stay length by travel distance, and recommends early reservations because weekend waiting lists are common; (936) 291-6196.

Huntsville Memorial Hospital on Memorial Hospital Drive operates a 24-hour emergency room.

For support beyond the unit itself, the Texas Inmate Families Association is a statewide nonprofit focused on education, advocacy, and prison-system navigation for families with someone in TDCJ custody; its helpline is (512) 371-0900.
