Summary
In the City of Monterey Park, Section 4.50.100(a) allows construction noise only between seven a.m. and seven p.m. Monday through Friday, and between nine a.m. and six p.m. on Saturdays, Sundays and holidays, exempting job sites from the chapter's regular dBA limits during those windows only.
(a) Construction Activities. Construction activities between seven a.m. and seven p.m. Monday through Friday, and between nine a.m. and six p.m. on Saturdays, Sundays and Holidays. Persons responsible for construction activities lasting longer than three days, for example and without limitation, the general contractor or property owner, must post notice at all entrances to the construction site listing the noise limitations on construction set forth in this chapter. Such notice must be titled in letters at least one inch in height and be placed at least five feet above ground level. Construction activities lasting longer than three days will require a temporary noise permit pursuant to this chapter.
Full Breakdown
Section 4.50.100 lists activities that are excused from the chapter's numeric noise level limits but must still follow the conditions the section sets out, and construction activities are the first of them. Under subsection (a), construction work is confined to seven a.m. to seven p.m. Monday through Friday, and nine a.m. to six p.m. on Saturdays, Sundays and the code's list of holidays (New Year's Day, Martin Luther King Day, Presidents' Day, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving and Christmas Day, per Section 4.50.020).
Any job that runs longer than three days triggers two further duties: the general contractor or property owner must post a notice at every site entrance, titled in letters at least one inch tall and placed at least five feet above ground, listing the construction noise limits, and the job also needs a temporary noise permit under the chapter. 'Construction activities' is defined broadly to include grading, demolition, alteration, repair or remodeling of existing structures and the use of power equipment for those activities, but the definition specifically excludes radios or other amplified music played on a construction site, which remain subject to the chapter's ordinary noise disturbance rules rather than the construction exception (Section 4.50.020).
Violations & Fines
Construction noise outside the seven a.m. to seven p.m. weekday window, or the nine a.m. to six p.m. weekend and holiday window, is a Chapter 4.50 noise disturbance. Since that chapter is not a designated infraction under Section 4.10.030, a violation defaults to the code's general misdemeanor penalty of up to $1,000 in fines, up to six months in jail, or both, under Section 4.10.020, in addition to any administrative citation the city elects to issue under Chapter 4.20.
