Legal Question in Landlord & Tenant Law in Illinois

Unfortunately, you've given us insufficient information to give you a definite answer. For instance, if you have a written year's lease and it expires July 31, 2025, the most warning landlords need to give tenants about future rent increases is typically 60 days, so your landlord is giving you more like 150-180 days, which is very generous. Which leads me to believe that you may have lived in the apartment for some time, perhaps at a rate that the landlord has been able to live with, but sees that this coming year no longer can. I have no idea. And, if you only have a month-to-month arrangement, technically the landlord only has to give you "30 days' notice" - which would take effect March 1st, so again it appears the landlord is actually trying to be very kindly giving you this much advance notice. But that shouldn't stop you from talking to him and making your case. If there's something else going on, such as that you have a lease that goes beyond August 1st and shows the $930 rate, then the landlord may not have the right to raise the rent. So you may want to take the lease, if there is one, to a local attorney to review.
