Construction in Riverside is permitted 7:00 AM to 7:00 PM Monday through Saturday and prohibited on Sundays and federal holidays, per RMC Chapter 7.35.
Riverside Municipal Code Chapter 7.35 exempts construction activity from general noise limits only when it occurs between 7:00 AM and 7:00 PM Monday through Saturday. Construction, excavation, grading, demolition, or alteration work on buildings is prohibited on Sundays and federal holidays absent a special permit from the Building and Safety Division. Contractors using impact tools, pile drivers, or large diesel equipment outside these hours require written authorization and must post notification to adjacent properties.
