Corvallis, OR Noise from Specific Sources: Low-Frequency Bass Limits (2026)

Corvallis regulates loud amplified sound, including bass-heavy systems, through two linked provisions in Chapter 5.03.030. Section 5.03.030.020.10 sets baseline maximum sound levels without a permit: 65 dBA daytime and 60 dBA nighttime (10:00 p.m. to 7:00 a.m.) in residential zones and 'all other areas,' measured at the receiving property line; 70/65 dBA in commercial, office, and mixed-use zones measured at the nearest residentially zoned property line; and 75/70 dBA in industrial zones. Anyone who wants to exceed those limits, for example running a concert PA system or a bass-heavy speaker rig, must obtain an amplified sound permit from the City Manager under Section 5.03.030.030, after paying the fee set in Chapter 8.03.

The permitted sound still cannot exceed 80 dBA at the receiving property line, and street traffic cannot be obstructed. Critically for bass complaints, the City Manager can attach 'limitations on low frequency amplification' as a permit condition, along with restrictions on hours of operation, speaker placement, event duration or frequency, sound monitoring, advance notice to neighboring properties, and a designated on-site contact. Failure to comply with any permit condition, including a low-frequency limitation, is itself a separate violation of Section 5.03.030.030. Unlawful amplified sound under Section 5.03.030.020.10 is a Class C Misdemeanor, while other unlawful noise under Chapter 5.03.030 is a Class A Infraction. This chapter was substantially rewritten by Ordinance No. 2026-12, Section 1 (Exhibit A), adopted March 16, 2026.
