Elections and Voting - 2021 Election Guide

To Register to Vote

To register to vote, you must:

  • be a U.S. citizen; 
  • be at least 18 years of age by election day; 
  • live in your precinct at least 30 days before the election; 
  • not be in prison/jail serving time for a conviction; 
  • not claim the right to vote elsewhere. 


Registration During Early Voting

Early Voting extends the registration period by allowing voters to register and vote until the Monday before an election. Guidelines limit when and where Early Voting registrants can vote – during the Early Voting period, voters must register and vote in person at one of the Clerk’s designated Early Voting locations.

Individuals wishing to vote during the Early Voting must bring two pieces of identification to register, one with a current address. Registrants must immediately cast their ballot after registering to vote.

Election Day Registration and Voting

On Election Day, voters who are not registered to vote can register and vote at their home precinct only. Any voter who is not registered and needs to know where to go to register and vote on Election Day can utilize the Clerk’s online Your Voter Information Tool to find their proper polling place by address or birthday.

Voters planning on registering to vote or updating their address on Election Day must bring two pieces of identification to register, one with a current address.
