Administrative rules are effective for specific periods of time. To determine a past obligation, or requirement, you may need to research historical administrative rules. The information on this page introduces you to the resources available.

There are a couple of things to keep in mind:

  • the office does not have the resources to conduct research for you, but will help you by appointment do your own research as resources and publication deadlines allow;
  • while some documents are available online going as far back as 1995, the Utah State Bulletin is available (PDF) from 01/01/1998, to the present;
  • electronic finding aids are available at the office for rules filed after July 1, 1987;
  • researching rules prior to July 1, 1987, will require you to visit the office and use paper finding aids (this will take time);
  • reviewing documents older than 2006, will require you to visit the Utah State Archives Research Center (300 S Rio Grande St., Salt Lake City, UT  84101, 801-533-3535).

To research an administrative rule, you will need to know as much information as possible. Any of the following information will be helpful:

  • the name of the regulating agency;
  • the date the rule was filed;
  • the File Number (a five-digit number assigned by the Office of Administrative Rules)
  • the date the rule was published in the Utah State Bulletin;
  • the date the rule was made effective;
  • the code reference (begins with an "R").


The Office of Administrative Rules has generated an MD5 hash for some of the files that can be downloaded from it's website. An MD5 hash is, in essence, a signature for a file. You can confirm the integrity of the files you download by comparing the MD5 hash the office generated with one that you generate. Various software packages are available that permit you to generate an MD5 hash such as MD5Summer (graphical user interface), winMD5Sum (graphical user interface), MD5SUMS (no graphical user interface), or File Checksum Integrity Verifier (no graphical user interface). If the hashes do not match exactly, then the integrity of the file is in question. Please contact the Office of Administrative Rules immediately if the hash numbers do not match.

  • 2016 Bulletin Indexes (PDF) indexing changes effective from 01/02/2016 through the current issue of the Bulletin.

Historical Indexes
