Lexington, KY Noise from Specific Sources: HVAC & Mechanical Noise (2026)

The LFUCG Code of Ordinances Chapter 14, Sections 14-70 through 14-80 regulate noise in Lexington. The ordinance does not set specific decibel limits for HVAC equipment. Instead, it uses a subjective standard: sound that annoys or disturbs a reasonable person of normal sensitivities constitutes a noise disturbance. Section 14-72 lists specific prohibited acts including operating machinery with rotating or reciprocating parts that creates a disturbance across dwelling unit boundaries. Mechanically powered devices used outdoors that create a noise disturbance are specifically prohibited between 11:00 PM and 7:00 AM, and before 9:00 AM on Saturdays and Sundays. HVAC condensers, compressors, and heat pump units would fall under these general provisions when they create sound audible across property lines at a level that disturbs neighbors. The mayor may grant variances under Section 14-74 for documented health hazards or unreasonable economic hardship. Complaints about HVAC noise can be filed through LexCall 311 at (859) 425-2255 for Code Enforcement follow-up, or through the Lexington Police non-emergency line at (859) 258-3600 for after-hours disturbances. Fines range from fifty to five hundred dollars per violation. Kentucky state law under KRS 525.060 also addresses unreasonable noise as part of disorderly conduct provisions.
