Pursuant to Chicago RLTO Section 5-12-030(a), “dwelling unit” is not limited to the apartment or condominium rented by the tenant. Dwelling Unit also includes the common areas of the building, parking facilities, and mailboxes. A Chicago landlord has a duty to make disclosures about code violations affecting the “dwelling unit” and common areas under Chicago RLTO Section 5-12-100(a). Because of the broad scope of “dwelling unit” under this section, a landlord’s duty may extend to disclosure of code violations affecting “appurtenant buildings” to the tenant’s building if those buildings are part of the same complex.
Pursuant to Chicago RLTO Section 5-12-030(b) a “landlord” includes agents and successors in interest. This broad definition helps relieve tenants of the impossible burden of discovering undisclosed owners. Chicago RLTO Section 5-12-090 makes an Agent who signs a rental agreement for an undisclosed landlord liable as a landlord themselves.
Pursuant to Chicago RLTO Section 5-12-030(c) “owner” is broadly defined under the Chicago RLTO. Anyone who has just “part” of the legal title to the property is an “owner,” and thus liable as a “landlord.” There is no de minimus exception under the Chicago RLTO. This definition allows Chicago tenants to sue one of many partners or trust beneficiaries for return of the whole security deposit.
Pursuant to Chicago RLTO Section 5-12-030(d) “person” is defined as any legal entity, human or not.
Pursuant to Chicago RLTO Section 5-12-030(f) “Rent” is defined as anything a landlord gets in exchange for letting the tenant stay in their apartment.
Pursuant to Chicago RLTO Section 5-12-030(g) a “rental agreement” does not have to be in writing.
