Full Breakdown
Chapter 8.80 of the Riverside County Code sets a countywide shielding-and-aim standard for outdoor lighting in unincorporated areas: fixtures must be located, adequately shielded, and directed so no direct light falls outside the parcel of origin or onto a public right-of-way, and luminaires cannot blink, flash, or rotate. Section 8.80.080 confirms motion- or noise-triggered security lighting is not exempt, it must meet the same shielding standard as any other fixture. Nonconforming lights installed before the 2011 ordinance had three to six months to comply. The Sheriff and Code Enforcement enforce the chapter; exemptions cover law enforcement, public property, monuments, holiday lights, and agricultural operations.

First violation in 180 days: infraction, minimum $100 fine. Second: minimum $250. Third and further violations within 180 days: misdemeanor, minimum $500 fine or up to six months in jail.
