Full Breakdown

Section 6.68.090(e) exempts construction, repair, remodeling, demolition, paving or grading noise from the chapter's decibel limits only while it stays within permitted hours: not between 8 p.m. and 6 a.m. weekdays, not from Friday 8 p.m. through Saturday 7 a.m., not from Saturday 8 p.m. through Sunday 7 a.m., and not after 8 p.m. any Sunday. An exception lets a contractor push past 8 p.m. to finish an unforeseen critical phase already underway.

Violations & Fines

Work outside the exempted hours loses the noise exemption and is enforceable as an infraction under § 6.68.230.

Frequently Asked Questions

Can a contractor ever work past 8 p.m.?
Yes, if an unforeseen condition means an in-progress phase must be finished, § 6.68.090(e) lets work continue until that phase concludes.
Does the exemption cover weekend daytime work?
Yes, construction noise is exempt during permitted daytime hours; it's only the evening/overnight and Sunday-evening windows that are barred.
