Tracy's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Tracy, California, there are 8 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.

Barking Dogs

Tracy declares it a nuisance, and unlawful, to keep or permit any animal, poultry, or household pet on your property that disturbs a neighborhood's peace with barking or other noise, under a standalone animal-noise provision separate from the City's general noise ordinance.

Key details: Standard: any sound that disturbs neighborhood peace. Covers: dogs, poultry, and all household pets. Legal effect: declared a public nuisance, unlawful. No numeric limit: disturbance-based, not decibel-based. In force since: prior code § 5-2.306, recodified 2021.

Keeping or permitting a barking dog or other noisy animal that disturbs a neighborhood is unlawful under Section 5.08.250 as a declared public nuisance, independent of any separate noise-ordinance citation. The Animal Services Officer or a Police Officer acting in that capacity can investigate a complaint and act on it using the enforcement powers set out for the Office of Animal Services in Section 5.08.120.

Decibel Limits

Tracy caps environmental noise by zone under a one-hour average sound-level standard: 55 decibels in residential districts, 65 in commercial districts, and 75 in industrial, agricultural and Aggregate Mineral Overlay zones. Repeated violations trigger a Community Development Director noncompliance notice and a required compliance, extension, objection or variation response within thirty days.

Key details: Residential limit: 55 dB one-hour average. Commercial limit: 65 dB one-hour average. Industrial/agricultural limit: 75 dB one-hour average. Noncompliance trigger: 3+ days in any 30-day period. Boundary properties: limit is arithmetic mean of zones.

Exceeding the § 4.12.750 decibel limit for the applicable zone is enforceable under §§ 4.12.860-4.12.870 as an infraction, misdemeanor, or public nuisance subject to summary judicial abatement by restraining order, injunction, or assessment. Anyone who exceeds the limit on three or more days in a thirty-day period first receives a Community Development Director notice of noncompliance under § 4.12.780 and has thirty days to comply, seek an extension, contest the findings, or apply to the Planning Commission for a variation before further enforcement follows.

Amplified Music & Outdoor Sound

Amplified sound is banned in Tracy's parks and at special events unless the city first approves it as part of a permit. TMC 4.16.150 covers parks, and TMC 4.40.140 covers street events, and in both cases the Parks and Community Services Director can cap the maximum decibel level and dictate the sound system's location to protect neighboring areas.

Key details: Park rule: Amplified sound banned without a facility permit. Event rule: Same ban for street/right-of-way events, TMC 4.40.140. Volume control: Director sets decibel limit per permit condition. Disclosure: Sound equipment must be listed on the application. Enforcement: Charged as a permit violation, not standalone.

Using amplified sound without the required permit condition is enforced as a violation of the underlying facility permit (TMC 4.16.050) or special event permit (TMC 4.40.030), not as a stand-alone offense. A park facility violation escalates under the citywide infraction schedule in TMC 1.04.030, from a $100 fine on a first offense to a misdemeanor on a third within twelve months; a special-event violation is charged directly as a misdemeanor under TMC 4.40.180, punishable by up to $1,000 or six months in jail.

Aircraft Noise

Tracy Municipal Code Article 27 creates an Airport Overlay Zone (AO) around Tracy Municipal Airport that layers extra restrictions on top of the underlying zoning. Under section 10.08.3620(f), no noise-sensitive use, as defined in the General Plan, may be built inside the airport's 1997 60 dB Noise Contour Line unless the structure incorporates sound-attenuating construction practices.

Key details: Noise threshold: 1997 60 dB Noise Contour Line. Governing zone: Airport Overlay Zone (AO), Article 27. Requirement: Sound-attenuating construction for noise-sensitive uses. Density cap, inner 5,000 ft: 25 people per acre. Structural coverage cap, inner 5,000 ft: 25% of net lot area.

Because AO Zone limits control except where a use conflicts with the underlying zoning per 10.08.3620, a noise-sensitive project that skips sound attenuation inside the 60 dB contour is not a permitted use, and the Community Development Department can withhold site plan and building permit approval. Projects that proceed without the required construction measures face standard Tracy Municipal Code zoning enforcement, including stop-work orders and required retrofits before occupancy is certified.

Leaf Blower Rules

Tracy exempts leaf blowers, lawn mowers, and other minor-maintenance equipment from its general noise prohibition, but only between 7:00 a.m. and 10:00 p.m. Municipal Code 4.12.840 applies that same window on weekdays, weekends, and federal holidays, so yard equipment noise outside those hours loses its exemption.

Key details: Exempt hours: 7:00 a.m. to 10:00 p.m.. Applies on: Weekdays, weekends, and federal holidays. Governing section: TMC 4.12.840. Equipment named: Lawn mowers, power-brushes, leaf blowers. Outside the window: Exemption does not apply.

Yard equipment noise outside the 7:00 a.m. to 10:00 p.m. window loses its TMC 4.12.840 exemption and can be cited as an infraction under the general noise prohibition, punishable under TMC 1.04.030 by up to $100 for a first offense, $200 for a second within 12 months, and $500 for each further violation in that period, becoming a misdemeanor after two convictions.

Construction Hours

Tracy bars heavy construction-type equipment noise overnight. Municipal Code 4.12.820(h) prohibits operating a pneumatic or air hammer, pile driver, steam shovel, derrick, or hoist between 10:00 p.m. and 7:00 a.m. when the noise is loud or unusual, complementing the City's separate 7:00 a.m.-10:00 p.m. window for minor property-improvement noise under Section 4.12.840.

Key details: Heavy-equipment curfew: 10:00 p.m. to 7:00 a.m.. Governing section: TMC 4.12.820(h). Minor-improvement window: 7:00 a.m.-10:00 p.m. (TMC 4.12.840). Equipment named: Pile drivers, air hammers, derricks, hoists. Nuisance notice trigger: 3+ violations in 30 days.

Operating pile drivers or similar heavy equipment during the 10:00 p.m. to 7:00 a.m. curfew is an infraction under TMC 1.04.030, punishable by up to $100 for a first violation, $200 for a second within 12 months, and $500 for each further violation in that period, escalating to a misdemeanor (up to $1,000 or six months in jail) after two convictions for the same provision.

Quiet Hours

Tracy bars loud noise between 10:00 p.m. and 7:00 a.m. under Municipal Code Section 4.12.820, singling out yelling, shouting, hooting and singing on public streets during those hours as an automatic violation of the City's general noise prohibition, backed by the citywide nuisance-noise ban in Section 4.12.810.

Key details: Curfew window: 10:00 p.m. to 7:00 a.m.. Governing section: TMC 4.12.820(d). First-offense fine: Up to $100. Repeat fines: $200, then $500. Misdemeanor threshold: 2 convictions in 12 months.

A citation under TMC 4.12.820(d) is an infraction under the City's general penalty code, TMC 1.04.030: up to $100 for a first violation, $200 for a second within 12 months, and $500 for each further violation in that period. A person convicted twice within 12 months for the same provision is guilty of a misdemeanor, punishable by up to $1,000 and six months in jail. Each day a violation continues counts as a separate offense under TMC 1.04.020.

Vehicle Noise

Tracy's noise ordinance separately bans unnecessary horn use and excessive exhaust noise from vehicles. Municipal Code 4.12.820(a) makes it unlawful to sound a horn except as a danger warning or in an unreasonably loud, harsh, or prolonged manner, while 4.12.820(f) requires a working muffler on any stationary engine, motorboat, or motor vehicle.

Key details: Horn use allowed: Only as a danger warning. Muffler requirement: Required on all vehicles/engines. Governing section: TMC 4.12.820(a), (f). First-offense fine: Up to $100. Repeat fines: $200, then $500.

A horn or exhaust-noise citation under TMC 4.12.820(a) or (f) is an infraction under TMC 1.04.030, punishable by up to $100 for a first offense, $200 for a second within 12 months, and $500 for each additional violation in that period. Two convictions for the same provision within 12 months make a further violation a misdemeanor, carrying up to a $1,000 fine, six months in jail, or both.

The Bottom Line

Tracy's noise ordinances 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.
