For complete information on voting and elections, see the Lake County Clerk's web site or the State Board of Elections web site.

Who Can Vote?

All citizens of the United States 18 years old by the election date who have resided in the precinct for 30 days prior to the election and are properly registered are eligible to vote in any national, state, or local election. In even-numbered years, 17-year-olds can vote if they will be 18 by the date of the general election.

When to Register

Voter registration is open any time up to 28 days preceding an election. This break allows time for the voter files to be prepared for the election. During this time, no new registrations, changes of addresses, or other administrative changes can be made to the voters' files. Regular registration reopens the second day after the election.

Legislation adopted in 2015 provides that unregistered qualified individuals may register to vote in their respective precincts on election day. These qualified individuals must provide two forms of identification, one that shows their signature, to complete the registration and then receive their appropriate ballot.

Grace Period Registration
Grace period registration is available Lake County Clerk's office, 18 N. County St., Waukegan, after the close of registration 27 days before each election. A voter who registers or changes address during this grace period must vote at the time of registration.
