Again, we apologize for the construction confusion! If you are visiting the courthouse, the best, and only, construction-free entrance to use is through the annex off the parking lot on the north side of the building. All other entrances are currently under some type of construction. PLEASE do not use the east door at this time. We have heavy construction just inside the entrance!

We are moving upstairs! Thank you for your patience as our office will be closed Tuesday May 19th, and Wednesday May 20th to settle in. Come visit us on 2nd floor of the courthouse later in the week.

"Where do I go?" A lot of changes are happening in the courthouse! Here is what you need to know when you come to the courthouse. First, construction is still happening, just on a smaller scale. Please be mindful of signs and barricades. Second, the Treasurer's Office and State's Attorney's Office are in the annex. You can use that entrance, or you can enter through the courthouse by using the brick archway. For security purposes, we will be restricting entrance to the courthouse via the door on the EAST side of the building or from inside through the annex.
