Full Breakdown
City Code section 4-5-4E, inside chapter 5's Noise Control Ordinance, makes it a prohibited act to operate or permit the operation of "any tools or equipment used in construction, drilling or demolition work" between 11:00 P.M. and 7:00 A.M. on weekdays, or at any time on Sundays or holidays, if the resulting sound crosses a residential real property boundary or reaches into a city council-designated noise sensitive zone above the Table II decibel caps referenced in the section. The carve-out for "domestic power tools" means a homeowner running a drill or circular saw in a garage is treated differently from a contractor's job-site equipment, though the exemption does not extend to commercial construction crews.
Because the restriction is tied to a residential property boundary rather than the job site itself, a crew working downtown away from housing faces a different practical exposure than one adjacent to a residential block. There is no permit process in the noise chapter to extend construction hours past the cutoff; the only relief is the general hardship variance route in section 4-5-5, under which the mayor weighs the burden on the contractor against the disturbance to residents before granting any conditioned, time-limited exception.
Violations & Fines
A crew running construction equipment past the weeknight cutoff or on a Sunday or holiday commits a municipal infraction under section 4-5-7, fined under section 1-3-2C, with each additional day of the violation treated as a separate offense. Enforcement officers can also issue a section 4-5-8 abatement order requiring compliance before any citation is filed, and the city or a resident can pursue an injunction under section 4-5-9 against a repeat offender.
