Eastvale Zoning Code Section 120.05.050 limits light spilling onto neighboring property: fixtures must be fully shielded or recessed, and illumination measured at the nearest residential structure or rear-yard setback line may not exceed one-tenth (0.1) footcandle, roughly the brightness of ambient moonlight.
The City of Eastvale sets a specific, measurable light-trespass standard in Zoning Code Section 120.05.050. The general rule in subsection (d)(2) requires all outdoor lighting to be constructed with full shielding and/or recessed to reduce light trespass to adjoining properties. The numeric standard appears in subsection (d)(3): illumination measured at the nearest residential structure or the rear-yard setback line of an adjacent residential property may not exceed the moon's potential ambient illumination of one-tenth (0.1) footcandle. In plain terms, light crossing onto a neighboring home or yard cannot be brighter than soft moonlight. This gives both residents and code enforcement an objective threshold to evaluate complaints about glare from a neighbor's floodlights, security lights, or commercial parking-lot lighting. The code pairs this with the fixture-height limits in subsection (d)(4) (18 feet near residential zones, 24 feet elsewhere) and, for athletic facilities, a requirement to minimize off-site glare and to turn lights off no later than 11:00 p.m. When light-trespass complaints arise, the city can require the property owner to re-aim, shield, or replace fixtures to bring the measured spillover at the property line within the 0.1-footcandle limit. Homeowners can avoid problems by choosing fully shielded, downward-aimed fixtures, using motion sensors and timers, and positioning lights so the beam stays on their own property.
Lighting that exceeds 0.1 footcandle at a neighbor's residence or rear-yard setback line, or unshielded fixtures causing glare, can result in code enforcement notices and orders to shield, re-aim, dim, or replace the offending fixtures.
