Rochester's Noise from Specific Sources: The Rules That Matter

Rochester maintains 123 local ordinances across all categories, and 3 of those deal specifically with noise from specific sources. Here is a breakdown of what the city actually requires, what is prohibited, and where Rochester falls on the strict-to-permissive spectrum compared to other cities.

HVAC & Mechanical Noise

Rochester's excessive-noise ordinance flatly exempts air conditioners from its property-line noise thresholds, so a running AC unit cannot be cited under the general curfew the way other sound sources can, per Municipal Code § 75-4B(6); other noise-sensitive protections in the chapter still apply.

Key details: Governing section: § 75-4B(6), Municipal Code. Exemption scope: Full exemption, no time-of-day limit. Compare to leaf blowers: § 75-4B(5) is limited to 8 a.m.-sunset. Other route: § 75-11 bars noise near schools, hospitals.

Because § 75-4B(6) exempts air conditioners outright, the City cannot cite a unit under the general excessive-noise penalties in § 13A-11 for simply running. A complaint alleging AC noise near a protected use like a hospital or school under § 75-11, or a separate property-nuisance claim, would instead carry whatever penalty applies to that other section.

Rochester is more permissive than most cities when it comes to hvac & mechanical noise. That said, there are still limits.

Delivery Truck Noise

Rochester's Noise chapter singles out loading and unloading for its own rule: City Code § 75-13 bars excessive noise from unloading a delivery vehicle or from opening, unloading or breaking down bales, boxes, crates and containers. The section carries no separate decibel or time standard, so what counts as "excessive" is judged case by case rather than against a fixed threshold like the tests written for other noise sources.

Key details: Governing section: City Code § 75-13. Covered activity: Loading/unloading vehicles, boxes, crates. Time restriction: None; applies at any hour. Enforcing agency: Chief of Police / Neighborhood Service Centers. First-offense fine: $25 ($50 if defaulted).

A § 75-13 loading-noise violation is referred to the Municipal Code Violations Bureau, where § 13A-11's general schedule applies: $25 for a first offense ($50 if defaulted), $35 for a second ($70 defaulted), and $65 for a third or subsequent offense ($130 defaulted). Because the section has no time-of-day exemption, excessive crate or pallet noise from an early-morning delivery is treated the same as noise at midday.

Rochester is more permissive than most cities when it comes to delivery truck noise. That said, there are still limits.

Generator Noise

Rochester's citywide noise ordinance bars "excessive noise" audible beyond a property line at night or 50 feet away by day, but City Code § 75-4B(8) specifically carves emergency generators out of that ban. The exemption applies to true emergency units; a generator run for convenience rather than an outage can still trigger the general excessive-noise standard.

Key details: Exempt source: Emergency generators, § 75-4B(8). General noise curfew: 10 p.m.-8 a.m. at property line. Daytime standard: Audible 50 ft, 8 a.m.-10 p.m.. Enforcing agency: Chief of Police / Neighborhood Service Centers. First-offense penalty: $25 ($50 if defaulted).

Running a true emergency generator carries no citywide noise penalty in Rochester; § 75-4B(8) exempts it outright. Noise that does violate Chapter 75, including generator use found not to qualify as an emergency, routes through the Municipal Code Violations Bureau under the § 13A-11 general schedule: $25/$50 for a first offense, $35/$70 for a second, $65/$130 for a third or later offense (initial penalty/default penalty).

Rochester is more permissive than most cities when it comes to generator noise. That said, there are still limits.

The Bottom Line

Compared to many U.S. cities, Rochester gives residents more room on noise from specific sources. 3 of the 3 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

Keep in mind that Rochester can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
