I found this info (Landlord Remedies Section 5-12.130 City of Chicago) so I think I could qualify under number 3.
Abandonment. Abandonment of the dwelling unit shall be deemed to have occurred when:
(1)Actual notice has been provided to the landlord by the tenant indicating the tenant's intention not to return to the dwelling unit; or
(2)All persons entitled under a rental agreement to occupy the dwelling unit have been absent from the unit for a period of 21 days or for one rental period when the rental agreement is for less than a month, and such persons have removed their personal property from the premises, and rent for that period is unpaid; or
(3)All persons entitled under a rental agreement to occupy the dwelling unit have been absent from the unit for a period of 32 days, and rent for that period is unpaid.
Notwithstanding the above, abandonment of the dwelling unit shall not be deemed to have occurred if any person entitled to occupancy has provided the landlord a written notice indicating that he still intends to occupy the unit and makes full payment of all amounts due to the landlord.
If the tenant abandons the dwelling unit, the landlord shall make a good faith effort to re-rent it at a fair rental, which shall be the rent charged for comparable dwelling units in the premises or in the same neighborhood. If the landlord succeeds in re-renting the dwelling unit at a: air rental, the tenant shall be liable for the amount by which the rent due from the date of abandonment to the termination of the initial rental agreement exceeds the fair rental subsequently received by the landlord from the date of abandonment to the termination of the initial rental agreement. If the landlord makes a good faith effort to re-rent the dwelling unit at a fair rental and is unsuccessful, the tenant shall be liable for the rent due for the period of the rental agreement. The tenant shall also be liable for the reasonable advertising expenses and reasonable redecoration costs incurred by the landlord pursuant to this subsection.
