Jefferson County, AL Outdoor Lighting: Light Trespass (2026)

Birmingham Code and Jefferson County zoning provisions prohibit light trespass - artificial illumination crossing onto neighboring property and causing nuisance conditions. Residential property line illumination limits typically 0.5 to 1.0 foot-candles measured at grade. Security lights including motion-activated floodlights must be aimed and shielded to illuminate only the owner's property. Floodlights deliberately aimed at neighboring homes or driveways, sometimes following neighbor disputes, are prohibited under Birmingham's general nuisance provisions and specific lighting standards. String lights, landscape lighting, and decorative illumination must not create glare for neighbors or vehicles on adjacent streets. Holiday lighting during the November-January season typically receives informal exemption from strict enforcement. Commercial properties face stricter standards with measured lumen limits at property boundaries (typically 0.1 to 0.5 fc depending on zone adjacency). Mountain Brook enforces some of the metro's most restrictive residential lighting standards through zoning and HOA covenants. Greystone, Ross Bridge, and Liberty Park HOAs commonly require submitted lighting plans for estate-scale landscape lighting. Complaint enforcement is common - disputes between neighbors over bright security lighting are among the most frequent code complaints in Birmingham suburbs. Resolution typically involves aiming, shielding, or replacing fixtures with downward-directed alternatives.
