Beaverton, Oregon HVAC Local Permit Ordinances and Codes
Beaverton, Oregon HVAC Permit Ordinances
In Beaverton, Oregon, the Building Division of the Community Development Department is the Authority Having Jurisdiction (AHJ) responsible for issuing building, mechanical, electrical, plumbing, fire systems, and demolition permits. They enforce the State of Oregon Building Codes, which govern construction standards. All permit applications, payments, and inspection requests are handled electronically through the Beaverton Electronic Permitting System (BEPS).
For HVAC work, a mechanical permit is generally required. However, if the work involves detached one- and two-family dwellings, townhouses, or accessory structures, or if it's limited to replacing furnaces, air conditioners, and heat pumps in multi-family buildings, a full plan review may not be necessary, and a mechanical trade permit can be obtained instead.
Specific Local Zoning or Fee Nuances:
Beaverton's Development Code, specifically Chapter 20, outlines zoning regulations, including allowed uses per zone, density, and other standards. Zoning maps are available to identify the zone applied to a property.
Regarding fees, Beaverton has a comprehensive fee schedule. Building permit fees are generally valuation-based and may include additional plan review and state surcharge components. Specific fee schedules for building permits, system development charges, and other related services are available. It's important to note that as of February 1, 2026, new comprehensive fee schedules have taken effect, with significant increases to many Planning application fees to better align with the city's costs for processing these applications.
A 12% surcharge is applied by the State of Oregon to all building, plumbing, electrical, and mechanical permits.
For specific details on permit costs and fee structures, it is recommended to consult the official Beaverton fee schedules or contact the Building Division directly.

Oregon, Washington Hvac Permit Regulations and County Ordinances for Unincorporated Areas
Oregon HVAC Permit Requirements
In Oregon, HVAC permit requirements are generally handled at the county or municipal level, with the state's Building Codes Division (BCD) setting the overarching framework. For properties in unincorporated areas, the BCD may directly handle permits, or the county may act as the authority having jurisdiction (AHJ). A mechanical permit is typically required for the installation, alteration, or repair of any part of a heating or cooling system, including ductwork and venting. This also extends to gas piping, furnaces, heat pumps, and air conditioning units. Even for like-for-like replacements of existing residential equipment, a permit is generally necessary. Homeowners performing their own mechanical work are still required to obtain the necessary permits and pass inspections, though they may be exempt from contractor licensing requirements under certain conditions. Permit fees vary by jurisdiction.
Washington HVAC Permit Requirements
In Washington, HVAC permit requirements are enforced at the county and municipal level, following the framework of the Washington State Building Code Act. Local jurisdictions (cities and counties) act as the AHJ for mechanical permits. Electrical aspects of HVAC installations are under the jurisdiction of the L&I Electrical Division. Permits are required for new HVAC installations, system replacements involving new equipment, and modifications to ductwork exceeding a certain size. Minor repairs, such as thermostat replacements, generally do not require a permit. For properties in unincorporated areas, the county building department serves as the AHJ. Washington's energy code compliance is closely linked to permit requirements, mandating that all permitted HVAC installations meet minimum equipment efficiency standards.
Unincorporated Areas
Oregon: In unincorporated areas of Oregon, the county typically serves as the authority having jurisdiction (AHJ) for building and safety matters, including HVAC permits. However, in some instances, the Oregon Building Codes Division (BCD) may directly handle permits for these areas. It is crucial to contact the specific county's building department to confirm their procedures.
Washington: In Washington, counties are responsible for enforcing building codes and issuing permits in unincorporated areas. Therefore, for properties outside of city limits, the county building department will be the primary point of contact for HVAC permit requirements and inspections.

Oregon Hvac Legislation, Codes, and Guidelines
Oregon HVAC Building Codes and Legislation
Oregon regulates heating, ventilation, and air conditioning (HVAC) systems through a series of state-specific specialty codes. These codes are updated periodically to incorporate modern standards, energy efficiency requirements, and safety protocols. As of April 2026, the primary codes governing mechanical systems in the state include the 2025 Oregon Mechanical Specialty Code (OMSC) and the 2023 Oregon Residential Specialty Code (ORSC).
The 2025 OMSC, which became mandatory on April 1, 2026, is based on the 2024 editions of the International Mechanical Code (IMC) and the International Fuel Gas Code (IFGC), with specific Oregon amendments. For residential construction, the 2023 ORSC provides the governing standards. Recent legislative and regulatory updates have introduced significant changes, including new requirements for heat pumps in certain new residential construction projects where split-system air conditioning is installed, aimed at improving energy efficiency and reducing long-term utility costs for homeowners.
Primary Regulatory Agencies
The administration and adoption of these building codes are managed by the following state entities:
- Oregon Building Codes Division (BCD): A division within the Department of Consumer and Business Services, the BCD is the primary agency responsible for adopting, administering, and enforcing the state's specialty codes, including the mechanical and residential codes.
- Residential and Manufactured Structures Board (RMSB): This board works with the BCD to review and approve updates to residential building codes, including recent measures regarding energy-efficient HVAC and heat pump mandates.
- Mechanical Board: This board collaborates with the BCD to adopt and administer the Oregon Mechanical Specialty Code.
- Construction Contractors Board (CCB): While the BCD sets the technical standards, the CCB is responsible for issuing specialty contracting licenses for HVAC work in the state.
