Corona Municipal Code Chapter 17.36 (Outdoor Lighting) and Title 17 zoning standards require shielded, downward-directed exterior lighting on commercial and multifamily properties to minimize light pollution and glare. Corona is not a designated Dark Sky community, but lighting must not trespass onto adjacent residential properties.
Corona's outdoor lighting standards in Municipal Code Chapter 17.36 and the city zoning code require all new commercial, industrial, and multifamily exterior lighting to be fully shielded so that no light source is directly visible from off-site, with all light directed downward toward the surface being illuminated. Maximum lumens per fixture, mounting heights, and luminance levels are specified by zoning district. Parking lot lighting must use full cutoff fixtures and turn off or dim significantly within 30 minutes after closing for non-24-hour businesses. Decorative landscape lighting is exempt if total wattage stays below specified limits. Single-family residential lighting is largely exempt from shielding requirements but cannot create a nuisance. The city is not designated by the International Dark-Sky Association, but the lighting standards align with general dark-sky principles to reduce skyglow over the Cleveland National Forest. Color temperature recommendations favor warmer (3000K or below) lighting to reduce blue-light pollution. Light intrusion across property lines into residential windows or yards is enforceable under both the lighting code and general nuisance provisions. New developments require photometric plans showing illuminance levels at property lines do not exceed 0.5 foot-candles in residential adjacency areas.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Corona code enforcement directly for current fines, enforcement procedures, and hearing options.
