Summary
Unincorporated Shasta County has no county-wide ordinance fixing construction hours. Construction timing is controlled project-by-project through use permits and environmental review; the County's only timing-related grading rule is a seasonal wet-weather window, not a noise limit.
Noise from construction activities is generated by two primary sources: 1) the transport of workers and equipment to construction sites, and 2) the noise related to active construction equipment. These noise sources can be a nuisance to local residents and businesses or unbearable to sensitive receptors. [Mitigation is applied through conditions of approval consistent with the General Plan Noise Element Section 5.11 standards of 55 dBA daytime / 50 dBA nighttime at noise-sensitive receivers.]

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.
Violations & Fines
There is no general construction-hours ordinance to violate; restrictions are enforced as conditions of a project's permit or CEQA mitigation. Off-hours construction that becomes a disturbance can still be addressed by the Sheriff under California Penal Code Section 415 or as a nuisance under County Code Chapter 8.28.
