Big Horn County, Wyoming Plumbing Permit Requirements

Big Horn County, Wyoming, does not have its own building codes for development in unincorporated areas. However, contractors are required to follow all applicable electrical and fire protection codes. For properties within town limits, it is necessary to contact the respective municipality for their specific building codes or requirements.

For any construction or development project in rural Big Horn County, a Development Permit Application must be completed and submitted to the Land Planning Department. This permit process helps determine if the project is affected by floodplain or airport zones and guides through related issues such as county road access, addressing, and septic systems.

In unincorporated areas of Big Horn County, specific plumbing permit requirements are not detailed. However, it is recommended to adhere to national building code standards for any improvement projects, especially if the property is intended for future sale. While minor repairs may not require a permit, new construction or system alterations likely will.

State-Level Plumbing Code Adoption in Wyoming

Wyoming does not mandate a single, uniform statewide plumbing code that is enforced by the state government for all construction. Instead, the state operates under a decentralized system where building codes, including plumbing standards, are primarily adopted and enforced at the local level by individual cities and counties. While the state government, through the Department of Fire Prevention and Electrical Safety, adopts specific building codes (such as the International Building Code) for state-regulated facilities, these state-level adoptions do not automatically impose a statewide plumbing code on all local jurisdictions.

Primary State Agencies and Regulatory Framework

The regulatory authority for building and fire safety at the state level is the Wyoming Department of Fire Prevention and Electrical Safety, overseen by the Council on Fire Prevention and Electrical Safety in Buildings. This council adopts specific model codes (such as the 2024 International Building Code and related I-Codes) that apply to state-regulated structures. However, for most residential and commercial construction, local municipalities and counties have the authority to adopt and amend their own plumbing codes. Consequently, contractors and property owners must consult their local building department to determine which specific edition of a plumbing code (e.g., the International Plumbing Code or Uniform Plumbing Code) is in effect in their specific jurisdiction.
