Lake County, CA Noise Ordinances: Outdoor Music (2026)

Outdoor and event music in unincorporated Lake County is regulated by the same Section 41.11 Performance Standards that govern other noise sources. The receiving-property-line one-hour Leq limits apply: 55 dBA day / 45 dBA night in residential and agricultural districts, with 57/50 dBA where the receptor is a dwelling or other sensitive use (Tables 11.1 and 11.2). The key carve-out is Section 41.11(e)(4), which exempts only 'non-electronically amplified sounds at sporting, amusement, and entertainment events' - acoustic crowd noise and unamplified performance, but not electronically amplified outdoor concerts or DJ systems. Because Lake County is a rural-resort area with wineries, resorts, and outdoor venues, larger outdoor-music uses are commonly authorized and conditioned through a use permit; the Chapter 13 nuisance definition (Section 13-3.1(e)(9)) expressly excludes noise 'already regulated through an approved use permit,' so a venue operating within its permit conditions is compliant, while an unpermitted or out-of-condition event remains subject to nuisance abatement. Section 41.11(f) lets the Zoning Administrator or Planning Commission conditionally authorize exceptions to the noise limits for infrequent noise as part of a use permit. These standards apply only in the unincorporated areas, not in Lakeport or Clearlake.
