Eugene, OR Noise from Specific Sources: HVAC & Mechanical Noise (2026)

750(f) targets fixed residential mechanical equipment, listing heat pumps, residential fans, air conditioners, stationary pumps, stationary cooling towers, stationary compressors, and similar devices, alone or in combination. If that equipment was installed after the effective date of the ordinance that added this subsection, Eugene bars operating it in a way that pushes the maximum noise level above 60 dBA at any point on the property line of the affected residential property. Because the limit is tied to the property line rather than a fixed distance from the unit, a compressor placed close to a shared lot line faces a tighter practical limit than one set back from neighbors.

The subsection was adopted by Ordinance No. 20680, enacted January 23, 2023, effective January 24, 2023, so equipment installed on or after that date is subject to the 60 dBA ceiling; the code text does not extend the limit to equipment installed earlier. 750(f) sits among the section's other specific prohibitions, including exhaust, idling, loading, construction, leaf blowers, and warning devices, all enforced the same way. 020, and neighborhood and adjacent-owner notice, with a decision due within 14 to 30 days.
