Brentwood prohibits short-term rentals citywide under Municipal Code Chapter 17.796 (Ord. 1079, adopted Dec 10, 2024), so STR-specific noise rules do not apply. Any rental of 30 days or fewer is unlawful, leaving Brentwood's general noise ordinance to govern occupant conduct at long-term rentals.
Because Brentwood's Municipal Code Chapter 17.796 (added by Ordinance No. 1079, adopted December 10, 2024) makes it unlawful to offer, advertise, or rent any dwelling for 30 consecutive days or fewer, the city does not maintain STR-specific quiet hours, occupancy caps, or party-house rules of the kind found in Contra Costa County's unincorporated STR ordinance (Chapter 88-32, Ord. 2020-12). Operators cannot create a local STR-noise compliance plan because hosting itself is prohibited, including hosted stays and stays in ADUs. For dwellings rented for 31 or more days, ordinary city noise standards apply through the general nuisance provisions and any applicable amplified-sound rules in the Municipal Code. Neighbors who experience suspected unlawful short-term rental activity report it to the City of Brentwood for code enforcement under Chapter 17.796.
Operating, advertising, or booking a stay of 30 days or fewer is itself a code violation regardless of noise. The city may pursue administrative citations, fines, civil remedies, and nuisance abatement; each day a violation continues can be treated as a separate offense.
