Full Breakdown
050, Outdoor Lighting, addresses light trespass, meaning light crossing onto a neighboring parcel, separately from the dark-sky rule that governs light aimed skyward. 1 requires all lights on a property to be directed, oriented, and shielded to prevent light trespass or glare onto adjacent properties, the public right-of-way, and driveway areas, a general performance duty that applies to every outdoor fixture citywide. 3 footcandles at the property line, and pole or wall-mounted fixtures cannot exceed 20 feet in height, or the height of the roof eave if attached to a single-family home.
b, with pole heights topping out at 25 feet in most nonresidential districts and 30 feet in manufacturing zones. 3 only if there's no light trespass or spillover onto adjacent properties, on top of separate mounting-height and wattage caps. 5. A lighting plan prepared by a qualified lighting engineer is required with most new-construction entitlement applications so the Community Development Department can confirm compliance before fixtures go in.
Violations & Fines
A homeowner or business whose outdoor lighting measures above 0.3 footcandles (residential) or one footcandle (nonresidential, on adjacent residential land) at the property line is in violation of Section 17.60.050, as is any fixture aimed or unshielded so it casts glare directly onto a neighbor's yard, a driveway, or the public right-of-way. The Community Development Department reviews compliance at entitlement and can require re-aiming, shielding retrofits, or fixture replacement through code enforcement.
