These county ordinances apply to unincorporated areas of Dallas County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Full Breakdown

Texas SB 4, enacted in 2017 and largely upheld by the Fifth Circuit, requires local law enforcement to honor ICE civil immigration detainer requests, prohibits policies restricting officers from inquiring about immigration status, and authorizes removal from office of sheriffs or officials who adopt sanctuary practices. Dallas County Sheriff's Office complies by holding individuals subject to ICE detainers up to 48 hours past their release date and notifying ICE before release. Dallas County is not a sanctuary jurisdiction. Earlier county practices that limited cooperation were withdrawn after SB 4. Civil penalties for non-compliant counties run $1,500 to $25,500 per day, plus loss of state grant funding under Texas Government Code Chapter 752.

Violations & Fines

Officials adopting sanctuary policies face civil penalties of $1,500 to $25,500 per day, removal from office under SB 4, and loss of state funding. Individuals harmed by violations of detainer rules may sue under Texas Tort Claims Act.

Frequently Asked Questions

Will Dallas County Sheriff hold me for ICE if I post bond?
Yes if ICE has filed a detainer. Under Texas SB 4, the Sheriff must hold you up to 48 hours past your scheduled release while ICE takes custody. Local refusal would trigger state penalties and removal from office.
Can a Dallas County city create its own sanctuary policy?
No. SB 4 preempts any city, county, or sheriff policy that limits cooperation with federal immigration enforcement. Officials adopting such a policy face civil penalties, removal, and loss of state funding.
