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

San Ramon restricts construction hours to protect residential peace and quiet, with standard hours of 7:30 AM to 5:30 PM Monday through Friday and 9:00 AM to 5:00 PM Saturday. Sunday and holiday construction is prohibited outright, including Memorial Day, Independence Day, Labor Day, Thanksgiving, Christmas, and New Year's Day. Restrictions cover all construction activity audible beyond the project property line: power tools, pneumatic equipment, heavy equipment, delivery of materials, grading, paving, pile driving, and generator use. Interior construction that is fully enclosed and inaudible at the property line may proceed outside these hours. Emergency repairs to utilities, structures posing immediate hazard, or urgent weatherproofing are exempt but should be reported to the Building Division. Major developments like Bishop Ranch expansions and Dougherty Valley residential projects operate under Conditional Use Permits that may specify additional construction management requirements, including staging hour restrictions, haul route timing, and neighborhood notification requirements. The City Engineer may issue a written exemption for specific projects requiring after-hours work (e.g., freeway-adjacent paving that requires lane closures), typically with 72-hour advance public notice. Violations carry administrative citations starting at $100, with general contractors held responsible for subcontractor compliance. Repeated violations can trigger stop-work orders issued by the Building Division. Homeowners doing their own work are subject to the same hour restrictions as licensed contractors.
