IDAPA is the Idaho Administrative Procedure Act, the state law codified at Idaho Code Title 67, Chapter 52 that controls how executive branch agencies write rules, enforce them, and resolve disputes with the people those rules affect. The same acronym also labels every administrative rule the state publishes, so an “IDAPA number” is simply the citation to a specific regulation adopted under the act. The framework applies to nearly every department in state government and sets uniform procedures for drafting a regulation, challenging an agency decision, and taking that decision to court.
How to Read an IDAPA Citation
Every Idaho administrative rule carries a unique identifier built from three pairs of digits separated by periods. The first pair identifies the agency, the second identifies the division or title within that agency, and the third identifies the specific chapter of rules. IDAPA 44.01.01, for example, refers to the rules of the Office of the Administrative Rules Coordinator (agency 44), division 01, chapter 01.1Office of the Administrative Rules Coordinator. IDAPA 44.01.01 – Rules of the Administrative Rules Coordinator Inside each chapter, individual sections run from 000 to 999, with further numeric and alphabetic subdivisions.
That structure is what lets lawyers, businesses, and ordinary citizens pinpoint a single rule across thousands of pages of state regulation. The Office of the Administrative Rules Coordinator manages the filing and indexing of every rule so that agencies do not duplicate or contradict each other.2Office of the Administrative Rules Coordinator.

How an Idaho Agency Makes a Rule
Rulemaking under IDAPA moves through recognizable stages, and the stage a rule is in tells you whether it is already binding, still open for comment, or waiting on the legislature.
Negotiated Rulemaking
Before an agency can formally propose a new rule or amend an existing one, it must decide whether negotiated rulemaking is feasible. Under Idaho Code 67-5220, negotiated rulemaking is a collaborative process in which the agency works with interested parties to reach consensus on the content of a rule before any formal proposal is published. The agency announces the effort in the Idaho Administrative Bulletin, describing the subject matter, the statutory authority, and how the public can take part.
During the process, the agency has to give the public a reasonable chance to respond, hold meetings with interested parties, share the non-exempt information it is relying on, and prepare a written summary of any issues left unresolved. If the agency decides negotiated rulemaking is not feasible, it must explain that choice in the notice of proposed rulemaking and move straight into the formal process.
Proposed, Pending, and Final Rules
Once negotiated rulemaking ends or is bypassed, the agency publishes a proposed rule in the Idaho Administrative Bulletin. The public then has at least 21 days to submit written comments or ask to present arguments orally, as required by Idaho Code 67-5222.
After weighing public input, the agency may adopt the rule as a pending rule. A pending rule has been formally approved by the agency but has not yet taken effect, because it still needs legislative review. Idaho’s germane legislative committees examine every pending rule to confirm it stays within the agency’s statutory authority and matches what lawmakers intended when they delegated rulemaking power.3Office of the Administrative Rules Coordinator. Legislative Rules Review Books Only after surviving that review does the pending rule become a final rule with the full force of law.4Idaho Department of Lands. About Rulemaking
Temporary Rules
Sometimes an agency needs a rule in place right away. Idaho Code 67-5226 allows temporary rules, but only if the Governor finds at least one of three conditions: the rule is needed to protect public health, safety, or welfare; it is necessary to comply with deadlines in new federal or state law; or it reduces a regulatory burden on individuals or businesses. A temporary rule takes effect as soon as it is adopted. It still goes through legislative review, and it expires if the legislature does not approve it during the next session.
Challenging an Agency Decision: Contested Cases
When an agency action directly affects someone’s rights or interests, that person can challenge the decision through a contested case hearing. Idaho Code 67-5240 defines a contested case as any agency proceeding that may result in the issuance of an order, which covers professional license revocations, permit denials, regulatory fines, and similar actions.5Idaho State Legislature. Idaho Code 67-5240 – Contested Cases Idaho’s Office of Administrative Hearings provides independent hearing officers to decide these disputes.6Office of Administrative Hearings. Office of Administrative Hearings
A contested case hearing looks much like a trial. A presiding officer runs the proceeding, requires full disclosure of relevant facts, and allows cross-examination where appropriate. Each party gets a chance to respond, present evidence, and make arguments.7Idaho State Legislature. Idaho Code 67-5242 – Procedures in Contested Cases
After the hearing, the presiding officer issues a preliminary order based solely on the evidence in the record. That preliminary order automatically becomes final unless a party appeals it to the head of the agency, who then issues the final order. Every order must include a reasoned statement supporting the decision, findings of fact tied to the record, and a description of the procedures and deadlines for seeking further review.8Idaho State Legislature. Idaho Code 67-5248 – Contents of Orders
Asking an Agency for a Ruling Before a Dispute
Not every interaction has to start with a fight. Under Idaho Code 67-5232, anyone can petition an agency for a declaratory ruling on how a statute or rule applies to a specific set of facts. A business unsure whether a regulation covers its operations can ask the agency to say so in advance, rather than risk a violation and litigate it later.
A petition for a declaratory ruling has to identify who you are and your interest in the matter, describe the ruling you want, and point to the specific statute or rule in question along with the facts behind the request. You can include citations to case law or other legal authority to strengthen your position.9Legal Information Institute. Idaho Admin Code r. 62.01.01.725 – Form and Contents of Petitions for Declaratory Rulings
Taking an Agency to Court: Judicial Review
A final agency order is not the last word. Under Idaho Code 67-5270, a person harmed by a final agency action can petition a district court for judicial review.10Idaho State Legislature. Idaho Code 67-5270 – Right of Review You have to exhaust all administrative remedies inside the agency first, as Idaho Code 67-5271 requires. The petition must be filed within 28 days of the final action, an order denying reconsideration, or the agency’s failure to act on a reconsideration request within 21 days, whichever comes last.
You file in the district court of the county where the hearing was held, where the final action was taken, where you reside or operate your principal place of business in Idaho, or where any real or personal property at issue is located.11Idaho State Legislature. Idaho Code 67-5272 – Venue, Form of Action
The court does not retry the case or hear new evidence. It reviews the agency’s record and can set the decision aside only on specific grounds: the action violated constitutional or statutory provisions, exceeded the agency’s authority, was made through unlawful procedures, or was arbitrary and capricious. When the agency was required to issue an order, the court can also reverse if the findings are not supported by substantial evidence in the record as a whole.12Idaho State Legislature. Idaho Code 67-5279 – Scope of Review, Type of Relief
One feature sets Idaho apart from many states. Idaho Code 67-5279 directs judges to interpret statutes and rules independently rather than defer to the agency’s reading, and to resolve any remaining doubt in favor of an interpretation that limits agency power and maximizes individual liberty. Even with that standard, the court will only overturn an action if the challenger shows that their substantial rights were actually prejudiced.
Where to Find Idaho’s Rules
Every rulemaking step is documented in the Idaho Administrative Bulletin, which publishes notices of proposed changes, public hearing schedules, and the text of temporary and pending rules. The full Idaho Administrative Code, with every current rule in force, is available online through the Office of the Administrative Rules Coordinator.2Office of the Administrative Rules Coordinator. Welcome to the Office of the Administrative Rules Coordinator Those resources let you look up the exact requirements an agency is enforcing, check that it followed proper procedure, and track proposed changes before they take effect.
