Summary
Kansas City's noise code does not apply to construction work at all: no decibel limit and no nighttime cutoff for genuine site-preparation, building, or demolition activity anywhere in the city.
The provisions of the noise code shall not apply to:
(1)The emission of sound for the purpose of alerting persons to the existence of an emergency;(2)The emission of sound in the performance of emergency work;(3)Construction work, as defined in section 46-3;(4)The unamplified human voice;(5)Interstate railway locomotives and cars;(6)Activities for which the director has issued either a special variance or special permit pursuant to the noise code;(7)Noise disturbances that are the result of any act of God, war, labor disturbance, riot, catastrophe or other cause beyond the control of a person; or(8)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.

Full Breakdown
City Code § 46-26 lists the activities the noise control code does not cover, and item (3) is "Construction work, as defined in section 46-3." Section 46-3 defines "Construction" broadly, site preparation, assembly, erection, repair, alteration, or demolition of rights-of-way, structures, or utilities, so bulldozers, saws, generators, and other job-site equipment fall outside Chapter 46's Table I decibel limits and its 10:00 p.m.–7:00 a.m. quiet hours. Section 46-5(2) separately excuses loading and unloading of materials "in the performance of construction work" from the late-night loading restriction that otherwise applies citywide.
Violations & Fines
Not applicable to genuine construction activity: it is exempt. Work that doesn't fit the § 46-3 definition (e.g., ordinary domestic power tools) loses the exemption and falls under the standard noise limits, enforced by administrative citation starting at $100 for a first offense under § 46-39.
