                                                          Under your fact pattern, ypu can serve an IL eviction notice by (i) certified mail (w/return receipt) or (ii) personal service (handing it to the defendant).  It is highly recommended that you get a third party server to complete option (ii), and attest in an affidavit to tenant's receipt.  Otherwise, your service may be deemed ineffective by the court.
