No. §8.36.050(C)(1) bars power construction equipment outside residential areas before 6:00 a.m. on weekdays, before 8:00 a.m. on weekends, or after 7:00 p.m. any day, unless the Chief Building Official grants a written variance under §8.36.050(C)(2).

Do construction-hour rules apply on commercial sites?
The §8.36.050(C)(1) restriction applies to construction or repair work 'in or adjacent to a residential area.' Sites that are not adjacent to residences default to the general dBA limits in §8.36.040, which are higher in commercial and industrial zones.
