Construction hours in Anza, CA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Construction noise in unincorporated Riverside County is generally limited to 6:00 a.m. to 6:00 p.m. Monday through Saturday, with no work allowed on Sundays or federal holidays.
Under Riverside County Ordinance No. 847, construction, demolition, grading, and related activity using powered tools or heavy equipment is restricted to daytime hours to protect residential areas. The standard permitted window is 6:00 a.m. to 6:00 p.m. Monday through Saturday; Sunday and federal holiday work is prohibited unless specifically authorized by the Building and Safety Department or the grading permit.

Interior work inside a closed structure that does not emit noise beyond the property line is generally allowed outside these hours. Contractors working on county capital projects may have separate hour conditions in their permits. Violations are enforced through Code Enforcement citations and can include stop-work orders for repeat offenders.
Administrative citations start around $100 and increase with repeat violations; serious or repeated violations can trigger stop-work orders and permit review.
