Kent treats neighbor light complaints as code nuisances. Lighting that directly shines onto another residential property, especially into windows, can be ordered corrected.
Light trespass (spillover onto neighboring property) is actionable in Kent under nuisance provisions of Kent City Code and the general property maintenance code. The most common triggers are security floodlights mounted high on garages that shine straight into a neighbor's second-floor bedroom, string lighting blasting into a backyard, and commercial parking-lot lighting adjacent to single-family homes. Kent Code Enforcement typically responds to a complaint by asking the offending owner to reposition, shield, or add a lower-wattage lamp. Continued violations after written notice can lead to civil infractions. On commercial sites the design standards in KCC 15 require full-cutoff fixtures and maximum foot-candle readings at the property line (commonly 0.5 fc at a residential boundary). Motion-sensor lights that trigger repeatedly due to wildlife can be asked to be re-aimed or time-limited.
