Full Breakdown
Fountain Valley does not write its construction rule as a standalone curfew. Section 6.28.070(5) of the Municipal Code exempts construction noise from Chapter 6.28 when the work happens inside set hours: seven a.m. to eight p.m. Monday through Friday, nine a.m. through eight p.m. on Saturday, and at no time on Sunday or any legal holiday. The exemption covers noise sources associated with the construction, repair, remodeling or grading of any real property, and it expressly counts saws, buffers, sanders, drills, sprayers and similar activity.
The practical effect is that work inside the window is shielded from the numeric limits, while work outside it is not. Section 6.28.050 caps exterior noise on residential property at 55 dB(A) from 7 a.m. to 10 p.m. and 50 dB(A) from 10 p.m. to 7 a.m., and Section 6.28.060 sets interior limits of 55 and 45 dB(A). A crew running a saw at 6:30 a.m. on a weekday, or a sander on a Sunday, is measured against those numbers. Section 6.28.145 separately bars loud, unnecessary and unusual noise that disturbs the peace of a residential neighborhood.
Grading has its own definition in Section 6.28.020: any excavating or filling of earth material conducted at a site to prepare it for construction or other improvements. Emergency machinery, vehicles or work, meaning efforts to protect, provide or restore safe conditions or to restore utility service, are exempt under Section 6.28.070(4) without the hour limits.
Landscape crews follow a different schedule. Section 6.28.070(9) allows landscape maintenance between seven a.m. and eight p.m. Monday through Friday, nine a.m. through eight p.m. on Saturday, and nine a.m. through six p.m. on Sundays and legal holidays, but leaf blowers are excluded and run under Chapter 6.10.
A contractor who cannot meet the hours can apply for a variance from the health officer under Section 6.28.120 with a seventy-five dollar fee. The application does not stop prosecution until a variance is granted.
Violations & Fines
Chapter 6.28 violations are misdemeanors under Section 6.28.150, and each day a violation continues is a separate offense. Section 1.16.010 sets the misdemeanor ceiling at a one thousand dollar fine, six months in County Jail, or both, and allows the prosecutor to charge an infraction instead, with fines of one hundred, two hundred and five hundred dollars for successive violations within one year.
