Full Breakdown
Section 17-70(j) of the Kirkwood Code folds construction noise into the general disturbing-noises ordinance at Section 17-69. m. on Sunday. Outside those hours, running noisy construction machinery is a violation regardless of how loud the equipment actually is, since the subsection ties the offense to the clock rather than a decibel reading. is not in violation the way a private contractor pouring concrete at that hour would be. The current hours were set by Ordinance No. 10714 on May 20, 2021, replacing whatever window preceded it.
Kirkwood Police and Code Enforcement field complaints about after-hours construction noise, and because Chapter 17 does not assign this subsection its own fine, a violation is punished under the general penalty at Section 1-14: not less than $5 nor more than $1,000, imprisonment up to three months, or both, with each day outside the permitted window counted as a separate offense.
