Tinley Park Vital Records
The Cook County Clerk Bureau of Vital Records handles all birth, death, and marriage records for Tinley Park. The office is at 118 N. Clark St., Room 120, Chicago, IL 60602. Call (312) 603-5656 for questions. Like most suburbs in Cook County, Tinley Park does not run its own vital records office. Everything goes through the county.
Cook County birth and death records start from 1871 and 1872. The Great Chicago Fire destroyed what came before. Birth and marriage records cost $15 for the first copy and $4 for each one after. Death records are $17 first and $6 each extra. These fees are the same across all of Cook County. You can mail requests to the clerk at P.O. Box A3390, Chicago, IL 60690. Walk-in service at the Clark Street office is usually faster. Mail takes about 20 business days, and genealogy requests often take longer than that.
Under the Vital Records Act (410 ILCS 535), genealogical copies are available for births 75 or more years old, deaths 20 or more years old, and marriages 50 or more years old. These copies get stamped "For Genealogical Purposes Only" and cannot be used for legal ID. You must request them by mail. They cannot be ordered online or through VitalChek.
Note: Suburban Cook County death records from 1910 to 1915 are missing from the county files, so check IDPH or IRAD for that gap.
State Genealogy Records for Tinley Park
The Illinois Department of Public Health holds birth and death records from 1916 forward for the entire state. If the Cook County Clerk does not have the record you need, IDPH is the next place to try. The IDPH genealogy page explains how to submit a request by mail. Genealogical copies cost $10 for a birth and $10 for a death. Processing takes about 12 weeks. There is no status check while your request is being handled.
You can order certified copies of recent birth and death records through VitalChek, which is the authorized online partner for IDPH. But genealogical copies cannot go through VitalChek. Those must be mailed in. The VitalChek site is still useful for getting certified copies when you need them fast and are willing to pay the extra handling fee.
The Illinois State Archives has free online databases that can help with Tinley Park genealogy. The Statewide Marriage Index goes from 1763 to 1900. The Death Index covers 1916 to 1950 in one file, and 1951 to 1972 in another. Public domain land sale records are searchable too. All of these are free and open to anyone. No account is needed.
Regional Archives for Tinley Park
The IRAD depository for Cook County is at Northeastern Illinois University, Ronald Williams Library, 5500 N. St. Louis Ave., Chicago, IL 60625. Call (773) 442-4506 to ask about hours and record availability. IRAD holds historical local government records for Cook County and Chicago, including older vital records, land deeds, naturalization records, and probate files. Research in person is free.
You can submit up to two names per mail or phone request at no charge. The Local Records Act (50 ILCS 205) provides the legal basis for preserving these records through the IRAD system. If a Tinley Park record is too old for the county clerk to locate, it may have been sent to IRAD for long-term storage. Checking there is a good step when the usual sources fall short.
How to Search Tinley Park Records
Start with what you know. Get the full name, an approximate date, and the type of record you need. Then figure out which office holds it. For most Tinley Park vital records, that means the Cook County Clerk. For records from 1916 forward, both Cook County and IDPH may have copies. For pre-1916 records, the county clerk or IRAD are your best bet.

Cook County Court Records
