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

Martinez has not adopted an Airbnb/VRBO-specific ordinance. Instead, noise from any rental dwelling is governed by Chapter 8.34 (Noise Control) of the Martinez Municipal Code, which is intended to implement the goals of the city's Noise Element by prescribing standards prohibiting detrimental levels of noise. Chapter 8.34 generally prohibits unreasonable, excessive, or annoying noise from any residential property, including amplified music, parties, and outdoor gatherings, and is enforced by the Martinez Police Department for active disturbances and by Code Enforcement for repeat patterns. Because the Contra Costa County STR ordinance (Ordinance 2020-12 / Chapter 88-32) applies only to unincorporated areas, the county's quiet-hours, occupancy and event-prohibition rules are not directly enforceable inside Martinez city limits. Where a Martinez dwelling operates under the city's bed-and-breakfast framework cross-referenced in MMC Section 22.04.051, conditions of approval typically require operators to manage guest behavior, post house rules, and provide a contact for complaints; a documented pattern of nuisance noise can support revocation of the underlying entitlement. Hosts should also be aware that California Civil Code's nuisance provisions and the city's general nuisance abatement procedures (Title 1) can be used by neighbors and by the city to address chronic noise from any rental, regardless of whether the use is formally registered.
