Summary
Downey exempts permitted construction, repair, and remodeling noise from its general noise chapter, but only if a valid City permit for the work is on hand; even then, work is barred between 9:00 p.m. and 7:00 a.m. except emergencies, and construction noise can never exceed 85 db(A) at any property boundary, per Municipal Code § 4606.5.
Construction, repair or remodeling equipment and devices and other related construction noise sources shall be exempted from the provisions of this chapter provided a valid permit for such construction, repair, or remodeling shall have been obtained from the City. In any circumstance other than emergency work, no repair or remodeling shall take place between the hours of 9:00 p.m. of one day and 7:00 a.m. of the following day, and no repair or remodeling shall exceed 85 db(A) across any property boundary at any time during the course of a 24-hour day.
