Noise from Specific Sources in Tracy, CA

Every city handles noise from specific sources a little differently. In Tracy, California, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Delivery Truck Noise

Tracy specifically regulates delivery-related noise between businesses and nearby homes. Municipal Code 4.12.820(i) requires delivery vehicle engines to shut off while stationary outside the 6:00 a.m.-11:00 p.m. business window, bars loading and unloading noise near residences between 10:00 p.m. and 7:00 a.m., and limits refrigeration units running overnight within 75 feet of homes.

Key details: Engine-off requirement: Outside 6:00 a.m.-11:00 p.m.. Loading/unloading curfew: 10:00 p.m.-7:00 a.m.. Refrigeration units: Off overnight within 75 ft of homes. Governing section: TMC 4.12.820(i). First-offense fine: Up to $100.

Violating any part of TMC 4.12.820(i), whether an idling delivery engine, late-night loading noise, or an overnight refrigeration unit, is an infraction under TMC 1.04.030: up to $100 for a first offense, $200 for a second within 12 months, and $500 for each additional violation, rising to a misdemeanor (up to $1,000 or six months in jail) after two convictions for the same provision.

HVAC & Mechanical Noise

Air conditioners, condensers, heat pumps, and other permanent mechanical equipment in Tracy fall under the city's noise control ordinance, which caps the one-hour average sound level measured at the property line: 55 decibels in residential zones, 65 in commercial zones, and 75 in industrial and agricultural zones. HVAC equipment gets no time-of-day or minor-maintenance exemption.

Key details: Residential zone limit: 55 dB at property line. Commercial zone limit: 65 dB at property line. Industrial/Ag/AMO limit: 75 dB at property line. Enforcing official: Community Development Director. Max civil penalty: $1,000 per violation per day.

A noise violation under Chapter 4.12 is a criminal infraction or misdemeanor under Section 1.16.020, prosecutable by the City Attorney or District Attorney with discretion to charge it as an infraction. The City may instead pursue civil enforcement under Section 1.16.060(b), which authorizes a court to assess a civil penalty of up to $1,000 per violation for each day the noise continues. The City can also issue an administrative citation under Chapter 1.28, with the fine amount set by a Council-adopted fee schedule and due within 30 days; a cited owner may request a hearing to contest the citation within that same 30-day window.

The Bottom Line

Tracy's noise from specific sources rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Tracy is broadly strict or permissive.
