Summary
Kansas City regulates generator noise under its general sound level limits, not a dedicated rule: except data centers get a narrow exemption for backup generator noise during power outages, exempt from the 80 dBA cap when measured at the property line.
Data centers (facilities operated by a business engaged primarily in data processing, hosting, and related services with installed electrical equipment having the capacity to draw at least 50 MW of demand) that are not exceeding sound levels of 80 dBA when measured at their real property boundary, excluding all ambient noise and noise caused by generators in the event of a power outage or interruption.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 139 | Zoning and Development Code: Supplement 38).
Full Breakdown
Kansas City's noise code (Ch. 46) has no standalone generator ordinance. Sec. 46-4 subjects every sound source, including standby and portable generators, to Table I's decibel limits, 60 dBA daytime and 55 dBA nighttime outdoors on residential receiving property, measured at the boundary. The only generator-specific carve-out is Sec. 46-26(8): data centers drawing at least 50 MW stay exempt from the code's 80 dBA cap for noise their backup generators make during a power outage or interruption. Homeowners and contractors get no such exemption; ordinary generator noise is measured like any other sound source.
Violations & Fines
Violations bring a director-of-health administrative citation: $100 for a first offense, $100–$300 for a second, $300–$500 for a third, and $500–$1,000 for a fourth or later violation, with each day counting as a separate offense.
