San Jacinto, CA Noise Ordinances: Construction Hours (2026)

San Jacinto Municipal Code § 8.40.090 sets the hours for construction activity noise. The erection (including excavation), demolition, alteration or repair of any building must occur between seven a.m. and seven p.m. on weekdays and Saturdays, and between nine a.m. and six p.m. on Sundays and holidays. Section 8.40.070(D) routes noise from construction, repair, remodeling, demolition or grading of any real property to this section rather than to the stationary decibel table.

The one built-in relief is a temporary use permit issued by the community development director or a designee. It requires a showing of sufficient need due to hot or inclement weather, the use of an unusually long process material, or other circumstances of unusual and compelling nature. Subsection B puts responsibility on the people directing the work: no landowner, construction company owner, contractor, subcontractor or employer can permit anyone working under their direction and control to operate a tool, equipment or machine in violation of the section.

The exceptions in subsection C are narrow. Emergency construction work by a private party is outside the hours when the city manager or a designee authorizes it. Public works by public employees or contractors are excepted, but that exception does not reach the City of San Jacinto, its employees, contractors or agents unless the city manager or a department head finds the work immediately necessary to maintain public services, the work cannot feasibly be done during normal business hours, or the city council has approved project specifications, contract provisions or an environmental document authorizing the off-hours work. Any construction that complies with the noise limits in § 8.40.040 or § 8.40.050 is also excepted. Work in public rights-of-way is exempted from the chapter by § 8.40.070(E), and other public agencies and utility companies can work at different hours in cases of necessity or emergency under § 8.40.100.
