Shasta County, CA Noise Ordinances: Construction Hours (2026)

Research of the Shasta County (California) code and General Plan found no blanket county-wide ordinance setting permitted construction or grading hours for the unincorporated area. The General Plan Noise Element (Section 5.11) sets exterior noise performance standards for new development, but those address the finished project's ongoing noise rather than temporary construction activity, which is typically handled on a case-by-case basis. The County's grading ordinance (Title 12) does impose a seasonal timing rule: grading planned between October 15 and May 1 generally requires a Wet Weather Erosion Control Plan (Section 12.12.070). That is an erosion and stormwater control measure, not a noise or daily-hours restriction. Where a project could create significant construction noise near homes, the County addresses it through conditions of approval, use permits, and CEQA mitigation rather than a stand-alone ordinance. Property owners should confirm any hour restrictions attached to their specific building or grading permit with the Shasta County Building Division (1855 Placer Street, Suite 102, Redding) and check whether their project lies within an incorporated city (Redding, Anderson, Shasta Lake), which has separate rules.
