Nevada Administrative Code (NAC) Research Guide

The Nevada Administrative Code (NAC) was ratified in 1987. New rules are sent to the Legislative Counsel Bureau and the Secretary of State. If you need old rules or want to know why a rule changed, you might have to contact the agency that made the rule. New or changed rules are published in the Nevada Register before they are added to the NAC. Each part of the NAC shows when it was added or changed and by which agency.

The NAC was ratified in 1987. When new regulations are adopted, copies are sent to both the Legislative Counsel Bureau and the Secretary of State.

Accessing Historical Regulations

• The Law Library can provide copies of historical regulations.
• For information on the intent behind a regulation or amendment, you may need to contact the adopting agency directly.

Updating the NAC

• The NAC is periodically updated after new or amended regulations are filed with the Secretary of State.
• To view the text of new or amended regulations before they're added to the NAC, check the Nevada Register of Administrative Regulations (available at the Law Library).

NAC and NRS Numbers

• NAC chapters correspond to chapters in the Nevada Revised Statutes (NRS).
• However, NAC section numbers do not match NRS section numbers.

Source Notes

Each NAC section has a source note that includes:

• The adopting agency
• The effective date of the section
• Dates of any amendments

Finding a NAC Chapter

Here is an example of NAC 341.015: 

The historical note will be at the end of each section. In this example, the Planning Board Policy, Procedures and Rules added this section in 1962; it was then amended in 1972, 1973, 1978, 1994, 2004, 2008 and 2012. 

When a regulation is amended, updates are published. The Law Library receives updated pages along with a "Letter of Transmittal."

The Letter of Transmittal includes:

• Contact information for the Legislative Counsel Bureau
• New chapters to be added
• Chapters to be removed or amended
• Any temporary regulations

The Law Library keeps a binder with all Letters of Transmittal, along with the amended and repealed chapters of the NAC. The Nevada Library Cooperative has some Letters of Transmittal in their collection, which can be found on the Superseded NAC page.
