Illinois voters may opt to vote-by-mail in all elections

11. You can deal with this

When you go to vote, tell the Election Judge your son no longer lives at the address as well as date he moved (month/year is sufficient). I review the list of eligible votes in my precinct (judge) to ensure a) people I know died are not on the list or b) people I know have moved (like from my neighborhood).

You can also notify the Election office for your county. If you still continue to get a voter card after doing one/both of the above, Illinois Board of Elections is your next step.

As to your rental, I'm surprised. Visit your local Post Office and I suspect you can fill out a form to notify addressee is no longer there. I did this to forward a deceased relatives mail to another relative (medical bills, final utility bills).
