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

030 lists 'Activities Prohibited' and 'Quiet Hours' as items 10 and 11 among the minimum standards every registered short-term rental must meet. Item 10 bars using the rental for commercial purposes or for events likely to result in violations of traffic, parking, noise, or other standards regulating the residential use and character of the neighborhood, expressly naming 'most weddings, corporate events, and parties' as examples of prohibited events. m. The host must brief guests on these limits in advance: item 6 requires a guest manual covering noise and quiet hours that is provided to every guest with the booking confirmation and displayed prominently in the unit.

020 is the enforcement backstop for noise complaints in real time, since that person must respond within sixty minutes to any complaint about the rental's operation or a guest's conduct and take remedial action, which for a noise complaint means addressing the disturbance directly with the guests during the quiet-hours window. A pattern of noise-related violations documented by City citation also counts toward the two-violation threshold that can lead to registration denial or revocation.
