Iowa Administrative Code

Administrative Rules Shown by Effective Date

Pursuant to Iowa Code section 17A.5(2), an adopted rule, with certain exceptions, may become effective at the earliest 35 days after publication in the Iowa Administrative Bulletin (IAB). A rule so adopted (or amended or rescinded) is codified and published in the Iowa Administrative Code (IAC) concurrently with the IAB, which means that in most cases, an adopted rule is not in effect on the day it is published (e.g., a rule adopted through the regular rulemaking process and published in the IAB and IAC on July 5, 2017, would not become effective until August 9, 2017).

To view an Executive Branch agency’s chapter or rule by reverse chronological order of effective date(s), select the agency from the drop-down menu below, then the chapter and, if applicable, the desired rule. A history of rulemakings* that affect the selected chapter or rule will then be generated in chart form. The chart will include the effective date, as well as the ARC number, publication date and subject of the rulemaking, PDF (and RTF, when available) of the selected agency, chapter, or rule as published in the IAC.

*The rulemaking data displayed below pertains only to rulemakings published on and after July 2, 2008. To access data pertaining to rulemakings published prior to July 2, 2008, or for assistance with interpreting the data or with other research of administrative rules, please contact the Publications Editing Office (Administrative Code) at AdminCode@legis.iowa.gov.

Pending or future rulemakings, or delays or suspensions by the General Assembly’s Administrative Rules Review Committee, that may affect the selected chapter or rule can be monitored by using the Rules Tracker tool, which is updated biweekly on the same day that the IAB is published.
