Washington, Chelan County Hvac Permit Regulations and County Ordinances for Unincorporated Areas
Chelan County Building and Safety Division
The Chelan County Department of Community Development, specifically its Building Division, is responsible for overseeing building and construction activities in unincorporated areas of the county. This division administers and enforces various codes, including the International Mechanical Code, to ensure public health, safety, and welfare. Their responsibilities include permit application intake, plan reviews, permit issuance, and conducting inspections during construction.
Permit Requirements for Unincorporated Areas
In unincorporated Chelan County, a mechanical permit is generally required for the installation, alteration, or replacement of HVAC systems, including furnaces and heat pumps. Property owners or their authorized agents must obtain these permits before beginning work. The permit process ensures that the installation complies with adopted state and county codes. Applicants are typically required to submit a mechanical permit application, which may include site plans detailing the location of equipment, such as heat pumps or air conditioning units, in relation to structures and property lines. It is important to note that if a property is located within an incorporated city, the city's own building department—not the county—handles the permitting process.

The following statewide building codes and regulations apply universally to all jurisdictions within Washington:
Washington Hvac Legislation, Codes, and Guidelines
Washington State HVAC Building Codes and Legislation
The Washington State Building Code is established by the state legislature under the Revised Code of Washington (RCW) Chapter 19.27. This statute mandates the adoption of specific national model codes, which are then amended at the state level to meet Washington's unique requirements for safety, energy efficiency, and indoor air quality.
As of the current standards, Washington utilizes the 2021 editions of the International Code Council (ICC) model codes, including the 2021 International Mechanical Code (IMC) and the 2021 International Residential Code (IRC). Additionally, Washington maintains its own state-specific energy and ventilation standards, known as the Washington State Energy Code (WSEC) and the Washington State Ventilation and Indoor Air Quality Code, which are codified in Title 51 of the Washington Administrative Code (WAC).
The primary agency responsible for the development, adoption, and amendment of these codes is the Washington State Building Code Council (SBCC). The SBCC is a governor-appointed body that advises the legislature on building code issues and ensures that the state's construction standards remain consistent and effective across all local jurisdictions. While the state sets these minimum requirements, local cities and counties are responsible for the enforcement of these codes and may adopt local amendments, provided they are not less restrictive than the state-level standards and, in many cases, receive approval from the SBCC.
