Lake County, CA Short-Term Rentals: Noise Rules (2026)

Because Lake County has not adopted a short-term rental ordinance, there are no STR-specific quiet hours or decibel limits aimed at vacation-rental guests in the unincorporated area. Noise from a rental home is instead governed by the County's general regulatory framework. The Zoning Ordinance's performance standards in Article 41 establish baseline limits on objectionable conditions, and several use standards in Article 27 cross-reference the County's noise limit at Section 21-41.11 (for example, recycling centers must not exceed those noise levels). Conduct that creates a public nuisance - loud parties, amplified music, or disturbances late at night - can be addressed by the Lake County Sheriff and through the County's nuisance-abatement authority regardless of whether the property is a short-term rental. Operators of a recognized Bed and Breakfast or Bed and Breakfast Inn must also meet the general performance standards of Article 41 as a condition of their zoning approval. Owners of vacation properties around Clear Lake, Kelseyville, Cobb, and Hidden Valley Lake should set clear house rules limiting late-night noise and amplified sound, since neighbor complaints are handled under these general nuisance and performance provisions rather than a tailored STR noise ordinance.
