Some RestrictionsBarking Dogs
Tustin formally adopted Orange County's Barking Dog Ordinance by reference into the Tustin City Code (Animals chapter), so OC Animal Care enforces it inside the city. A dog is a barking-dog nuisance with 30+ minutes of incessant barking, or 60+ minutes of accumulated intermittent barking, in a 24-hour period. Civil fines escalate with repeat citations.

Some RestrictionsAircraft Noise
Aircraft-in-flight noise is federally preempted: the FAA and pilot-in-command have sole jurisdiction over flight paths, so Tustin cannot regulate overflights. Section 4617(j) of the Tustin City Code exempts activity preempted by state or federal law. Former MCAS Tustin closed in 1999; nearby John Wayne Airport has an 11 p.m.-7 a.m. jet curfew set by the County.

Few RestrictionsIndustrial Noise
Industrial property in Tustin (Noise Zone 3) is capped at 70 dB(A) at any time under Section 4614, but fixed noise sources such as compressors, fans, generators and HVAC must still not push a quieter neighboring zone over its own limit. Tustin Legacy mixes uses, so a Zone 5 mixed-use ceiling of 60 dB(A) may apply at sensitive boundaries.

Some RestrictionsOutdoor Music
Outdoor music in Tustin is held to the Section 4614 exterior limits reduced 5 dB(A) because it is music. Permitted outdoor gatherings, public dances, shows and entertainment events run under a city permit (Tustin City Code Art. 3, Ch. 2) are exempt from the decibel standards under Section 4617(b). Other venues are bound by their zone's limits.

Some RestrictionsVehicle Noise
Tustin's noise chapter does not set vehicle-specific decibel limits; loud exhaust and muffler enforcement on public roads is controlled by the California Vehicle Code (Secs. 27150-27151), which preempts local muffler rules. Stationary or property-based vehicle noise (idling, repairs) still falls under Tustin City Code Section 4614's zone limits.
