Galt, CA Outdoor Lighting: Light Trespass (2026)

Galt does not set a specific numeric foot-candle limit for residential light trespass, but unwanted light spilling onto a neighbor bedroom window or outdoor living area may be abated as a nuisance under the Galt Municipal Code general nuisance provisions and California Civil Code Section 3479. Commercial developments must meet photometric property-line limits (typically 0.1 to 0.5 foot-candles) established during design review. For existing residential fixtures, code enforcement staff will document the lighting condition, consult with both property owners, and typically request voluntary shielding, aiming adjustments, or timer installation before issuing formal citations. Common remedies include adding a hood or baffle, lowering fixture height, installing a motion sensor so lights are not on continuously, or replacing bulbs with lower-lumen options. Festival and holiday lighting is generally tolerated for limited periods but extended bright-light installations that affect a neighbor year-round may be subject to complaint. Commercial signage lighting is regulated through the sign code and building permits.
