Chicago Lease Failure to Provide Heat Disclosure - Remedy

[Frank S.]

Hey, 

I always include the heat disclosure on my leases. It only takes a few clicks online. 

What are the remedies for a Tenant where the Heat Disclosure wasn't provided? I know of a case with a lease starting in August. The heat hasn't been used,  but the disclosure wasn't provided. 

Can they terminate the Lease by notification?

Can they sue to get all of their money back?

Or,

Is this a minor offense of the

Chicago Residential Landlord and Tenant Ordinance (RLTO) and remedy is just a fee?

Thanks
