Pick the situation. The period on each card is Illinois's minimum β your lease can require more, never less.
No statewide period; 2 days in Chicago.
Allowed. Tell the tenant afterwards what happened and what was done.
Repairs, inspections, showing the unit to prospective tenants, buyers or contractors, and supplying agreed services.
