Kent, WA Outdoor Lighting: Light Trespass & Shielding (2026)

050, the city's citywide performance standards chapter, which was written to keep land uses from creating dangerous, injurious, noxious or objectionable conditions, including glare alongside noise, vibration, odor and hazardous substances. Subsection (C) fixes where compliance is measured: in every district, at the property lines or lot lines, or at a 50-foot buffer setback line for a hazardous substance land use facility. Subsection (D)(3) then bars any direct or sky-reflected glare, whether from floodlights or from high-temperature processes such as combustion or welding, that is visible at that measurement point, but carves out an exception for signs or building floodlighting otherwise permitted for advertising or protection purposes.

090(G) requires that lighting of any parking lot or storage area illuminate only that lot or storage area and be designed and located to avoid undue glare or reflection onto adjoining properties or public rights-of-way, and bars light standards from interfering with parking stalls, maneuvering areas, or ingress and egress. 050(B). The planning director reviews lighting plans for compliance during permit review; a property owner who believes a neighboring use is casting glare across the line can raise it as a performance-standard issue under Title 15.
