Quick answer
A mechanical permit is required for residential HVAC work in Eugene, and the city issues it as a trade permit through eBuild with no plan review for straightforward jobs. Fees are charged per piece of equipment, but because every residential item costs less than the $114.50 minimum permit fee, a typical single-appliance replacement lands on that minimum. Filters, volume dampers, fresh air intakes, duct work, thermostats and control units are folded into the base fee rather than charged separately.

What an HVAC permit costs in Eugene
How to apply in Eugene
In Eugene, a residential HVAC (mechanical) permit application must identify the covered equipment and scope of work, since installing, altering, or replacing a heating or cooling system is regulated work that cannot start until the application is submitted and the permit issued. The equipment itself must be picked by a real sizing calculation rather than a rule of thumb.
What most HVAC permit applications include:
- For Eugene, a mechanical permit is required before anyone may install, alter, repair, remove, convert, or replace a heating, ventilating, or air conditioning system regulated by the code, and the work may not begin until the application is submitted and the permit is issued (IRC R105.1).
- For Eugene, the application identifies the specific equipment being installed, such as a furnace, heat pump, or air conditioner, since the unit must be installed according to its listing and the manufacturer's installation instructions (IRC M1401.1).
- For Eugene, the proposed equipment location must leave the clearances needed to clean coils and replace filters, blowers, motors, and controls after installation (IRC M1401.2).
- For Eugene, the application carries the equipment sizing basis: ACCA Manual J building loads and Manual S equipment selection, or another approved sizing method, not a rule of thumb (IRC M1401.3).
- For a split system, the work covered by the permit includes refrigerant suction line insulation, since the piping is inspected against that standard once installed (IRC M1411.6).

Inspections and closing out your permit
In Eugene, mechanical work gets a rough in inspection after the ductwork, refrigerant lines, and gas piping are in but before they are covered or concealed, followed by a final inspection that confirms the equipment operates correctly and its clearances, combustion air, and condensate disposal are in place. A straight equipment changeout with no new ductwork commonly gets a single final inspection instead of a separate rough in trip.
- In Eugene: rough inspection of the mechanical and gas systems must be made before the work is covered or concealed, before fixtures or appliances are set or installed, and before the framing inspection (IRC R109.1.2).
- In Eugene: where a cooling coil is added to an existing warm air furnace, the rough in confirms the coil is not installed upstream of the heat exchanger unless the furnace is listed for it, and that the blower can handle the added static pressure (IRC M1411.2).
- In Eugene: the rough in and final both confirm the appliance access opening and working space are large enough to service the unit (IRC M1305.1).
- In Eugene: at final inspection, the inspector verifies the equipment has adequate combustion air, with openings kept clear for the distance the code requires (IRC M1402.3).
- In Eugene: final inspection also checks that the condensate line drains to an approved point of disposal with the required slope and does not create a nuisance (IRC M1411.3).
- In Eugene: for a straight equipment changeout with no new ductwork, many permit offices require only a single final inspection, while a new installation still gets a rough in inspection before the final (common local inspection practice).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Eugene permit portal or by phone at 541-682-5086.

- Confirm the requirement. Yes, a permit is required. Usually needed: Before installing or replacing a furnace, heat pump, air conditioner, air handler, woodstove, fireplace insert or gas boiler, before running new or altered gas piping, and before altering or adding to existing duct work.
- Budget the fee. Eugene's Residential Mechanical Permit Application (Form #F-304, updated July 2026) prices one- and two-family work per item: exhaust and ventilation (clothes dryer exhaust, exhaust fan, kitchen hood, whole-house ventilation) $22.95; fuel burning equipment (woodstove, fireplace insert, gas furnace, gas boiler, includes vents and flues) $44.30; other equipment (electric furnace, heat pump outdoor unit, ductless heat pump indoor units, air handlers, air conditioner) $30.35; gas piping system, new or altered, any number of outlets, $24.30; alterations and additions to existing duct work $28.10.

- Where do you apply for an HVAC permit in Eugene?
- You can apply through the Eugene permit portal or contact the City of Eugene Building and Permit Services, Planning and Development Department directly. The links are listed on this page.
- Can a homeowner pull an HVAC permit themselves in Eugene?
- Under Oregon law (ORS 701.010(7); ORS 701.325(1), (2), (3)): A homeowner may pull the permit and do the work. ORS 701.010(7) exempts from Construction Contractors Board licensing a person performing work on property that person owns, or on that person's own residence whether or not they own it, so no CCB license is needed to act as your own builder. That exemption does not cover someone working in the pursuit of an independent business with intent to offer the structure for sale. Oregon does require a signed disclosure at the counter: ORS 701.325(1) makes every city, county, or state permit office collect a written statement signed by the applicant, and an applicant claiming a licensing exemption must state the basis for it. ORS 701.325(2) requires the office to give the applicant the Information Notice to Property Owners About Construction Responsibilities and withhold the residential building permit until the applicant signs a statement, one option of which is that they are performing work on property they own or a residence they live in or will live in, and that any contractors they hire will be CCB licensed and properly endorsed. The Information Notice itself is a CCB rule form under ORS 701.325(3) covering payroll tax, workers' compensation, and liability and property damage insurance responsibilities.
