Eastvale, CA Outdoor Lighting: Dark Sky Rules (2026)

The City of Eastvale addresses outdoor lighting and night-sky protection through Zoning Code Section 120.05.050. The core requirement, in subsection (d)(2), is that all outdoor lighting be constructed with full shielding and/or recessed to reduce light trespass to adjoining properties, which is the central dark-sky principle of directing light downward rather than out and up. Freestanding light fixtures are limited in height under subsection (d)(4) to 18 feet where they abut residential zones and 24 feet in other locations, keeping light sources lower near homes. For larger lighting installations such as athletic facilities, subsection (d)(8) imposes a curfew: sports-field lights must be turned off within one hour after the end of the event and in no case later than 11:00 p.m., which limits late-night skyglow. The code also addresses glare from athletic facilities, requiring measures to minimize off-site glare. While Eastvale is not a formally designated International Dark-Sky community, these shielding, height, and curfew provisions function as practical dark-sky controls. Homeowners installing yard, façade, or driveway lighting should choose fully shielded fixtures, aim them downward, and avoid spilling light onto neighboring properties. New commercial and residential development lighting plans are reviewed against Section 120.05.050 during the entitlement and building permit process.
