No. Chapter 88-32 does not set a numerical decibel limit or a county-wide quiet-hours window. The operating standard is that excessive noise inconsistent with residential use is prohibited.

Who responds to a noisy short-term rental complaint in unincorporated Contra Costa County?

The Contra Costa County Sheriff's Office responds to active disturbances and can cite under California Penal Code 415 (disturbing the peace).

Do these rules apply inside cities like Walnut Creek or Concord?
