Short-term rentals are entirely prohibited in Concord, so STR-specific noise rules do not exist. Any unpermitted rental under 30 days is itself a zoning violation. Concord's general noise ordinance (Municipal Code Ch. 9.05) and 10 PM-7 AM quiet hours still apply to all residential properties.
Concord uses a permissive zoning code: only uses expressly listed in the Development Code are allowed, and short-term rentals are not listed as a permitted use in any residential or mixed-use zone. The city's planning division confirms that renting all or any portion of a property for fewer than 30 days, or listing on Airbnb, VRBO, Swimply, HomeToGo, or any similar platform, is prohibited citywide. Because no STR program exists, there is no STR-specific quiet-hours regime, no occupancy-based decibel cap, no dedicated complaint hotline for guests, and no STR permit that can be revoked for noise. Standard noise rules under Concord Municipal Code Chapter 9.05 apply to every dwelling: residential quiet hours run 10 PM to 7 AM, with a nighttime exterior limit of 45 dBA at residential property lines and a daytime limit of 60 dBA. Disturbances at an unpermitted STR can be reported to Concord PD's non-emergency line at (925) 671-3333 or through the Concord Connect app, and the underlying STR use itself can be reported to Planning at zoning@cityofconcord.org. Operators advertising or running an STR may also be treated as landlords under Concord's Residential Tenant Protection Program (Municipal Code Ch. 19.40), which can trigger relocation-payment obligations when occupants leave.
Operating an STR is itself a zoning violation regardless of noise. Noise breaches can lead to citations under Ch. 9.05, misdemeanor charges under California Penal Code 415 for repeat or willful disturbances, and code-enforcement abatement of the underlying use.
