In Adams County, Washington, the Building Division of the Adams County Building and Planning Department is responsible for enforcing building codes and safety standards. This division oversees permit applications, plan reviews, and inspections for construction projects. It is important to note that Adams County, Washington, is distinct from Adams County, Colorado, and users should ensure they are accessing information for the correct jurisdiction.
Permit Requirements for Unincorporated Areas
The Adams County Building Division reviews permit applications for all building projects located within the unincorporated areas of the county, as well as the Towns of Lind, Hatton, and Washtucna. Generally, most types of construction work, including repairs and additions, require a building permit. Because HVAC installations involve mechanical, electrical, and structural components, property owners should contact the Building Division directly to confirm if their specific HVAC project requires a permit. For work involving factory-assembled structures or manufactured homes, such as furnace changes, permits are often required through the Washington State Department of Labor and Industries.

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.
