Attention legal experts regarding Illinois laws and lease agreements?

Seems very odd that a car parked with a valid pass visible would be towed if parked in a proper parking space. Usually when they issue these passes they also ask for the tag number of the car that it will be used for, so they can match them up. So something does not seem right here, or they improperly towed him.

You do need to add him as an authorized resident right away. This is not "getting him on the lease", but rather is the landlord giving him permission to reside on the premises for more than a few days and not be considered a trespasser. So do this right away.

While there, ask them about the towing. They will best be able to tell you what the situation was that caused them to have it towed. Until you do that, you and we can only make guesses.

Yes the fact remains that he is not on the lease & is an unauthorized tenant. If the parking pass was not properly displayed then yes they have every right to tow it.

Yes marital status is a protected class in some states NOT all and being married does not make him a legal resident. It just makes it illegal to discriminate based on being married or not. He can still be required to be on the lease.

"Martial Status" is a protective class, also if the LL/management has known for years of your Husband living in the rental and has done nothing then legal theory of Laches can come into play as well

If he's not a legal resident, he can have his car towed. You can also be evicted for having an illegal occupant living on the property.
