About the office
Members of the Texas State Senate serve four-year terms and are not subject to term limits. Texas legislators assume office at the beginning of the legislative session, which starts at noon on the second Tuesday in January in the year after the election.[1][2]
One-half of the Senate membership is elected every two years in even-numbered years, with the exception that all 31 Senate seats are up for election for the first legislature following the decennial census in order to reflect the newly redrawn districts. After the initial election, the Senate is divided by lot into two classes, with one class having a re-election after two years and the other having a re-election after four years.[3]
Qualifications
To be eligible to serve in the Texas State Senate, a candidate must be:[4]
- A U.S. citizen
- A qualified elector
- 26 years old before the general election
- A five-year resident of Texas before the general election
- A district resident for one year prior to the general election

Vacancies
If there is a vacancy in the Texas State Legislature, the governor must call a special election to fill the vacant seat.[6] A governor's proclamation to hold a special election must be delivered to county judges in the legislative district no later than 36 days before the scheduled election.[7]
The secretary of state can declare a candidate duly elected in a special election if there is no opposition.[8]

District map
Redistricting
- See also: Redistricting in Texas
In Texas, both congressional and state legislative district boundaries are drawn by the Texas State Legislature. These lines are subject to veto by the governor.[9]
If the state legislature is unable to approve a state legislative redistricting plan, a backup commission must draw the lines (the backup commission is not involved in congressional redistricting). This backup commission, established in 1948, comprises the following members:[9]
- Lieutenant governor
- Speaker of the Texas House of Representatives
- Attorney general
- State comptroller
- Commissioner of the General Land Office
The Texas Constitution requires that state legislative districts be contiguous and "that they preserve whole counties when population mandates permit."[9]
2020-2023
Texas renewed its state legislative district boundaries in June 2023 for use in 2024 and until the 2030 census. These districts were the same as those enacted by the state in October 2021. Gov. Greg Abbott (R) signed HB 1000 — establishing state House district boundaries — on June 12, 2023, and he allowed SB 375 — establishing state Senate district boundaries — to become law without his signature on June 18, 2023.[10][11]
The Texas Tribune's James Barragan wrote in January 2023 that Senate Legislative Redistricting Committee Chairwoman Joan Huffman (R) said the state was re-doing the redistricting process "to ensure that Legislature had met its constitutional requirement to apportion districts in the first regular session after the publishing of the results of the federal census, which is done every 10 years. Because of the pandemic, census numbers were not released until after the end of the last regularly scheduled legislative session on May 31, 2021. Redistricted maps were passed in a subsequent special session that year."[12] Texas had originally enacted new state legislative districts on October 25, 2021.
Below are the maps in effect before and after the 2020 redistricting cycle. The map on the right was in effect for Texas' 2024 state legislative elections.
