Our Champaign County landlord-tenant attorneys discuss the time needed to give a tenant to move out in Illinois. In Illinois, if there is no lease or if the lease does not specify a move out date, the Landlord must give at least 30 days of notice to a tenant that the landlord wants to move out. This notice must be in writing and must arrive to the tenant at least 30 days prior to their move out date. The written notice must also include a specific move out date for when the tenant must be out of the property and their tenancy has ended.
