Eugene, Oregon HVAC Local Permit Ordinances and Codes
Eugene, Oregon HVAC Permit Ordinances
In Eugene, Oregon, HVAC installations and modifications are regulated by the City of Eugene's Building and Permit Services department, which acts as the Authority Having Jurisdiction (AHJ). The state of Oregon administers the mechanical permitting system through the Oregon Mechanical Specialty Code (OMSC), but local jurisdictions like Eugene are responsible for issuing permits and conducting inspections.
Permit requirements can vary based on the type of HVAC project. Generally, permits are required for installations or changes to heating or cooling systems that involve venting, unvented appliances, wood stoves, gas piping, or exhaust systems. Even simple equipment replacements, like a furnace swap in a single-family home, typically require a mechanical permit and inspection.
Specific Local Zoning or Fee Nuances for Eugene:
Eugene's Community Development Department publishes a separate fee schedule for permits, which differs from statewide schedules. Permit fees are generally based on the value of the work performed for commercial projects, while residential projects may have specific fee structures. For commercial mechanical, fire systems, or medical gas permits, fees are calculated based on the date of application submittal and the estimated total project value.
The City of Eugene offers online tools and calculators to help estimate permit fees, such as the Commercial Mechanical Fee Calculator and the Residential Permit Fee Estimating Worksheet. Specialty permits, including electrical, mechanical, and plumbing permits that do not require a plan review, can be submitted online through the eBuild system.
While specific zoning ordinances directly related to HVAC installations are not detailed in the provided search results, Eugene's general zoning code governs land use, lot size, building setbacks, and height restrictions. Any HVAC installation must comply with these overarching zoning regulations. For detailed information on specific zoning requirements or fee schedules, it is recommended to contact the City of Eugene's Building and Permit Services directly.

Lane County HVAC Permit Requirements
Lane County, Oregon, requires permits for most HVAC installations, alterations, and replacements. The county's Building & Safety Division is responsible for issuing these permits and ensuring compliance with the Oregon Mechanical Specialty Code (OMSC).
Unincorporated Areas
Properties in unincorporated areas of Lane County are subject to the same permit requirements as those within city limits. The Authority Having Jurisdiction (AHJ) for these areas is typically the county itself.
Permit Application Process
- Permits can be applied for online through the ePASS or ePermitting websites, in person, by mail, or by email for Building and Sanitation permits only.
- Contractors should use ePermitting for residential mechanical, electrical, and plumbing permits, as well as commercial electrical permits. Homeowners and other agents can use the ePASS website for other permit types.
- Required documentation may include scaled site plans, equipment information/spec sheets, ComCheck data/Energy Envelope, Manual J load calculations, REScheck compliance, equipment efficiency specs, and duct design plans, depending on the project.
- Permit fees vary based on the project's approximate construction cost, planning fees, and sanitation fees. A permit fee calculator is available on the Lane County website.
When Permits Are Required
- Installation or alteration of any part of a heating or cooling system that requires venting.
- Installation or modification of systems that include ductwork.
- Installation, repair, or alteration of gas piping.
- Installation of wood stoves or fireplace inserts.
- Replacement of HVAC equipment, as this is generally not exempt from permitting in Oregon.

However, the replacement, alteration, or new installation of HVAC equipment is generally not exempt.

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.
