Relevant Illinois State Law

Notwithstanding any other provision of this Code to the contrary, each election authority shall establish procedures for the registration of voters and for change of address during the period from the close of registration for an election until and including the day of the election. During this grace period, an unregistered qualified elector may register to vote, and a registered voter may submit a change of address form, in person in the office of the election authority, at a permanent polling place established under Section 19A-10, at any other early voting site beginning 15 days prior to the election, at a polling place on election day, or at a voter registration location specifically designated for this purpose by the election authority. Grace period registration and changes of address shall also be conducted for eligible residents in connection with voting at facilities under Section 19-12.2 of this Code. The election authority shall register that individual, or change a registered voter's address, in the same manner as otherwise provided by this Article for registration and change of address.

If a voter who registers or changes address during this grace period wishes to vote at the election or primary occurring during the grace period, he or she must do so by grace period voting. The election authority shall offer in-person grace period voting at the authority's office, any permanent polling place established under Section 19A-10, and at any other early voting site beginning 15 days prior to the election, at a polling place on election day, where grace period registration is required by this Section; and may offer in-person grace period voting at additional hours and locations specifically designated for the purpose of grace period voting by the election authority. The election authority may allow grace period voting by mail only if the election authority has no ballots prepared at the authority's office. Grace period voting shall be in a manner substantially similar to voting under Article 19A.

  • (i) the election authority's main office and
  • (ii) a polling place in each municipality where 20% or more of the county's residents reside if the election authority's main office is not located in that municipality.

The election authority may establish other grace period registration and voting sites on election day provided that the election authority has met the notice requirements of Section 19A-25 for permanent and temporary early voting sites.
