Nevada Administrative Code (NAC): Adoption and Challenges

The Nevada Administrative Code, or NAC, is the official collection of all codified regulations created by Nevada’s executive branch agencies. These regulations fill in the practical details that state statutes leave open, covering licensing requirements, environmental standards, gaming rules, and much else. The Legislative Counsel Bureau classifies, arranges, and publishes the NAC, which makes it the authoritative place to find the specific rules agencies enforce day to day.¹

How the NAC Relates to the Nevada Revised Statutes

Nevada law operates on two levels. The Nevada Revised Statutes (NRS) are the broad laws passed by the Legislature. The NAC contains the detailed regulations agencies write to carry those laws out. A statute might say the state will regulate air quality; the corresponding NAC chapter spells out the specific emission limits, testing schedules, and permit applications that businesses actually deal with.

This two-tier system exists because legislators cannot anticipate every technical detail a regulatory program requires. The Legislature delegates authority to agencies with the relevant expertise. NRS Chapter 233B, the Nevada Administrative Procedure Act, establishes the rules that govern this delegation and the process agencies must follow when creating regulations.²

A regulation can never contradict or exceed the authority granted by its parent statute. If an agency writes a rule that goes beyond what the Legislature authorized, that rule can be struck down through legislative review or challenged in court. Nevada courts look to the enabling statute first when evaluating whether an agency stayed within its lane.

How the NAC Is Organized

NAC chapter numbers mirror the NRS chapters that authorize them. If you are looking at NRS Chapter 445A, the implementing regulations sit in NAC Chapter 445A. One caveat matters: while the chapter numbers match, the individual section numbers within those chapters do not. You need to browse or search within the correct NAC chapter rather than assuming a section-for-section match.³

The current text of the NAC lives on the Nevada Legislature’s website, where you can search by keyword, pull up a specific chapter, or browse the full index. The Legislative Counsel is responsible for numbering, formatting, and including each permanent regulation in the code.²

Finding Regulations That Are Not Yet Codified

The NAC contains only permanent regulations in their final, codified form. Newly adopted rules can take time to appear there. To track what is in progress, Nevada publishes the Nevada Administrative Register, a separate compilation of proposed, adopted, emergency, and temporary regulations along with the notices and informational statements that accompany them.⁴ If a rule has recently changed or is still working its way through adoption, the Register is where to look.

How Agencies Create and Adopt Regulations

The Administrative Procedure Act lays out a mandatory sequence that every agency must follow to create or change a permanent regulation. Skipping steps can make the resulting rule vulnerable to challenge.

Drafting and Legislative Counsel Review

An agency begins by submitting its proposed regulation to the Legislative Counsel Bureau. The Legislative Counsel reviews the language, revises it if necessary, and determines whether the proposal stays within the legal authority the Legislature granted. Agencies do not need to submit polished legal text at this stage; a summary of what the agency wants to accomplish can be enough, since the Legislative Counsel Bureau will rework the language anyway.⁵

Public Notice, Workshops, and Hearings

After the Legislative Counsel approves or revises the proposed text, the agency must give at least 30 days’ public notice before its first hearing on the regulation. The agency also must post the version it plans to consider on its website at least three working days before the hearing.²

During this period, the agency holds public workshops and hearings where anyone can comment on the proposed rule. Agencies are required to respond to the comments they receive before formally adopting the regulation, so public participation can genuinely shape the final text.

Small Business Impact Evaluation

Before holding a workshop, the agency must determine whether the proposed regulation is likely to impose a direct and significant economic burden on small businesses or directly restrict their formation, operation, or expansion. If either answer is yes, the agency must prepare a small business impact statement that summarizes the expected burden and considers ways to reduce it.²

Legislative Commission Approval

Formal adoption by the agency is not the final step. The agency must submit the adopted regulation and an informational statement to the Legislative Counsel, who forwards it to the Legislative Commission for review. The Commission reviews the regulation at its next regularly scheduled meeting (if received more than 10 working days before that meeting) or refers it to its Subcommittee to Review Regulations.²

If the Commission or Subcommittee approves the regulation, the Legislative Counsel files it with the Secretary of State and the regulation becomes enforceable. If the Commission objects, finding that the regulation exceeds the agency’s statutory authority or is inconsistent with legislative intent, the regulation is returned to the agency with a notice of objection. This review power gives the Legislature an ongoing check on executive branch rulemaking between legislative sessions.

Emergency and Temporary Regulations

Not every situation allows for the full permanent rulemaking process. Nevada provides two faster paths, each with built-in limits.

Emergency Regulations

When an agency determines that an emergency exists, it submits a written statement explaining the emergency to the Governor. If the Governor endorses the statement in writing, the regulation can take effect immediately upon filing with the Secretary of State, without prior public notice or hearing. An emergency regulation lasts no longer than 120 days, and an agency can use the emergency procedure only once for the same regulation.² If the agency wants the rule to survive past 120 days, it must separately adopt a permanent or temporary version through the regular process. Once that replacement regulation takes effect, the emergency version expires.

Temporary Regulations

Agencies can adopt temporary regulations between August 1 of an even-numbered year and July 1 of the following odd-numbered year without going through the full rulemaking procedure. These temporary regulations expire by limitation on November 1 of the odd-numbered year. The window aligns roughly with the period between legislative sessions, letting agencies act on new laws without waiting for the full permanent process. A substantively identical permanent regulation can then be adopted to replace the temporary one.²

How to Petition for a Regulatory Change

You do not have to wait for an agency to decide a regulation needs updating. Under NRS 233B.100, any interested person can petition an agency to adopt, amend, or repeal a regulation. The petition must include relevant data, views, and arguments supporting the requested change. Each agency sets its own form and submission procedure, so check the specific agency’s website before filing.⁶

Once the agency receives your petition, it has 30 days to either deny it in writing (with an explanation of its reasons) or begin formal rulemaking proceedings. There is no guarantee the agency will agree with you, but the denial must be substantive. If the agency does initiate rulemaking, the proposal follows the same notice-and-hearing process described above.⁶

Challenging a Regulation in Court

If you believe a regulation is invalid because it violates the Nevada Constitution, conflicts with a state statute, or exceeds the agency’s authority, you can file a declaratory judgment action in district court. You can file in Carson City or in the county where you live. Before going to court, you must first ask the agency itself to rule on the regulation’s validity. The agency whose regulation you are challenging becomes a party to the lawsuit, and you must also serve a copy of the complaint on the Attorney General.⁷

If the court finds that the regulation violates constitutional or statutory provisions, or that the agency exceeded its statutory authority, the court will declare the regulation invalid. Agencies can also file their own declaratory judgment actions to establish that their regulations are valid, an option they occasionally use when a rule’s legality is in doubt.

Watch the deadline. Challenges based on procedural defects in how a regulation was adopted must be filed within two years of the regulation’s effective date. After that window closes, you can no longer argue that the agency failed to follow the notice, hearing, or other procedural requirements of the Administrative Procedure Act. Challenges based on the substance of the regulation, meaning claims that it exceeds authority or violates the constitution, are not subject to this two-year limit.⁸
