Voting Precincts in Sebastian — Sebastian, Florida

Sebastian, incorporated in Indian River County on Florida's Treasure Coast, is the most populous city in the county, with an estimated 25,759 residents as of the U.S. Census Bureau ACS 2023. All electoral functions serving Sebastian — voter registration, precinct boundary assignment, polling place designation, and early voting administration — are the responsibility of Indian River County rather than the city government. The Indian River County Supervisor of Elections operates as the sole authority for these functions within Sebastian's boundaries, as documented on the City of Sebastian's Election Information page. The Florida Division of Elections provides a statewide precinct lookup tool, last updated April 9, 2026, that covers Indian River County precincts including those serving Sebastian. Sebastian's median age of 57.6, substantially above Florida's statewide median of approximately 42, reflects a large retiree population and shapes the electorate that participates across the city's polling places.

The Indian River County Supervisor of Elections is Leslie Rossway Swan, whose office is located at 4375 43rd Avenue, Vero Beach, FL 32967. Swan was first appointed to the position on March 7, 2011, subsequently elected in 2012, and ran unopposed in 2016, 2020, and 2024, according to the Supervisor's official biography. The office can be reached by phone at 772-226-4700 and administers the full range of electoral services for Sebastian residents, including voter registration, precinct assignments, absentee and mail ballot processing, early voting site management, and Election Day polling place operations, as documented by the Florida Division of Elections.

The Florida Division of Elections, a division of the Florida Department of State, maintains a Voter Precinct Lookup tool that was last updated April 9, 2026, and covers all registered voters in Indian River County. That tool allows a registered voter to identify their specific precinct number and assigned polling location by entering their registration details. The Indian River County Supervisor of Elections website (voteindianriver.gov) is the county-level authoritative source for current precinct boundaries, polling place addresses, early voting schedules, and candidate filing information.

Sebastian is served by multiple Indian River County precincts. The VoterFocus Precinct Directory for Indian River County documents several polling locations within Sebastian's boundaries. Precinct 5 uses 1805 N Central Avenue, Sebastian, FL 32958 as its polling place. Precinct 7 uses 281 Delaware Avenue, Sebastian, FL 32958. The Sebastian Elks Lodge is also listed in the VoterFocus county precinct directory as a polling location serving the Sebastian area.

Precinct boundaries in Indian River County are established and maintained by the Supervisor of Elections office and are subject to revision following decennial census-based redistricting. Registered voters in Sebastian are assigned to a specific precinct based on their residential address; that assignment determines both the Election Day polling place and the ballot style received, which may include county, state, and federal races with varying district boundaries. The county-administered precinct finder at voteindianriver.gov is the definitive tool for confirming a given address's current precinct assignment.

Sebastian City Hall Council Chambers, located at 1225 Main Street, has served as an early voting location for primary elections, as documented on the City of Sebastian's Election Information page. Early voting schedules, including specific dates and hours, are set by the Indian River County Supervisor of Elections office and vary by election cycle; the Supervisor's website (voteindianriver.gov) is the authoritative source for current early voting information.

Voter registration for Sebastian residents is administered entirely by the Indian River County Supervisor of Elections. The North Indian River County Library, located at 1001 Sebastian Boulevard, is listed by the Supervisor of Elections office as a voter registration site, providing a locally accessible point for residents to submit or update registrations. Florida maintains a statewide voter registration system, and registration status can be verified through the Florida Division of Elections or the county Supervisor's office. Voters who move within Sebastian may need to update their registration to ensure accurate precinct assignment; address changes that cross precinct boundaries alter a voter's assigned polling place.

Sebastian's municipal elections are distinct in structure from county and state races, though they use the same county-administered precincts and polling infrastructure. The City of Sebastian operates under a council-manager form of government, as documented in the City's Annual Comprehensive Financial Report and on the City Council page. The five-member City Council is elected at large by Sebastian voters, meaning all registered voters in the city — regardless of precinct — are eligible to vote in all council seat races. Following each annual election, the seated council elects a Mayor and Vice Mayor at a Special Meeting; the Mayor is therefore not directly elected by the public but chosen by fellow council members from among themselves.

The City Manager is appointed by the City Council and serves as the Chief Operating Officer for day-to-day city operations, according to the City Manager's office page. Municipal election ballots — administered through the county's precinct system — cover only council seats and any city ballot measures; county, state, and federal offices appear on the same ballot in general and primary elections where those races are concurrent. Candidate filing and ballot preparation for city races are coordinated between the City of Sebastian and the Indian River County Supervisor of Elections.

In March 2026, the Indian River County Supervisor of Elections office issued a press release noting a candidate petition deadline of May 11, 2026, signaling an active 2026 election cycle for county and state offices whose districts encompass Sebastian precincts. Sebastian residents participate in those races through the same Precinct 5, Precinct 7, and other county-designated polling places used for all Indian River County elections.

The City of Sebastian held a Regular City Council Meeting on November 12, 2025, as documented in the city's Agenda Center. Leslie Rossway Swan, who has served as Supervisor of Elections since her appointment on March 7, 2011, ran unopposed in the 2024 election cycle, maintaining continuity in county electoral administration through the current period. The Florida Division of Elections statewide precinct lookup tool was last updated April 9, 2026, and remains the state-level resource for confirming precinct assignments in Indian River County ahead of upcoming 2026 contests.
