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

Cities that permit STRs commonly attach quiet-hours and good-neighbor conditions to the permit. Tustin has no STR permit and therefore no STR-specific noise condition. Per the City's official FAQ, short-term rentals are prohibited and any sub-30-day residential rental is a banned hotel/motel use. Noise from any property in Tustin — owner-occupied, long-term rental, or an illegal short-term rental — is governed by the City's general noise regulations in the Tustin City Code (the Public Welfare provisions, Article 6 of the City Code, address noise). These set citywide standards on excessive, disturbing, and nuisance noise and are enforced by Code Enforcement and the Police Department. They are not tailored to vacation rentals and do not establish STR-only quiet hours or require a posted house-rules noise policy, because no lawful STR exists to attach such conditions to. In practice, complaints about a party house or noisy illegal rental are handled two ways: the noise itself is cited under the general noise ordinance, and the underlying unpermitted transient use is pursued by Code Enforcement as a prohibited hotel/motel use in a residential district. A homeowner who instead rents long-term (30 days or more) is simply a normal residential occupant subject to the same general noise rules as any neighbor.
