Light trespass is handled by city zoning, not Anoka County. Blaine, Coon Rapids, and other cities require outdoor lighting to be shielded and directed so it does not shine onto neighboring residential property or create glare across lot lines. Many Minnesota cities cap spillover light at their property boundaries.
Anoka County does not regulate residential light trespass inside cities; your city zoning code does. Standard Minnesota municipal practice requires all exterior lighting to be shielded and arranged so illumination is reflected away from adjacent residences and does not cast objectionable glare across property lines. Many Minnesota cities set a numeric spillover limit at the property line and a separate limit measured from the centerline of a public street, and require security and floodlight fixtures to be aimed and shielded. Enforcement is usually complaint-driven: if a neighbor's light shines into your home, the city can require the fixture to be shielded, re-aimed, or dimmed. Confirm the exact foot-candle limits with Blaine, Coon Rapids, or your city.
Persistent light spilling onto a neighbor can be cited as a zoning or nuisance violation; the city may order the owner to shield, redirect, or reduce the light, with fines under city ordinance.
