Summary
Rochester's only numeric decibel standard in the Zoning Code applies to public utility facilities, not to noise generally. Section 120-144H caps utility noise at 66 decibels by day and 45 decibels at night, measured at the lot line of any adjoining residential or planned development property. The City's general noise law elsewhere uses distance and time-of-day audibility tests instead of a dB meter.
The level of noise emanating from such use shall not exceed 66 decibels (dB) by day and 45 dB by night measured at any lot line which is also the lot line of a property in a residential or planned development zoning district, or a permitted or specially permitted residential use in any other zoning district, if the residential use was established prior to the establishment of the utility.

Full Breakdown
Rochester regulates noise two different ways depending on the source. m. Chapter 75 has no numeric dB threshold anywhere in its text. The Zoning Code takes a different approach for one specific use: public utilities. ' The same section requires utility structures to sit back at least 25 feet from all property lines, prohibits parking or storage in the front setback, requires screening and landscaping, and bans outdoor storage of vehicles and equipment on the site. Because the dB cap is tied to Subsection H's specific use category, it does not apply to bars, construction sites, traffic, or residential noise generally; those fall back on the audibility-based rules in Chapter 75.
Violations & Fines
Exceeding the 66/45 dB limit at a protected lot line is a zoning violation for the utility operator, enforced by the Director of Zoning and Permitting under §§ 120-203 through 120-206. City Court violations carry a fine of up to $500 or 15 days in jail per offense under Municipal Code § 52-3A(1), with each day of the exceedance a separate offense. Noise complaints against non-utility sources are instead handled under Chapter 75's audibility standard.
