Blaine, MN Outdoor Lighting: Light Trespass & Shielding (2026)

Blaine's light trespass standard sits in Sec. 129-2(c), immediately following the fixture-shielding rule in subsection (a). No light or combination of lights, including illuminated signs, casting light onto a public street may exceed a one footcandle meter reading measured at the edge of the roadway. A stricter limit applies where light crosses onto homes: no light or combination of lights casting light on a residentially zoned property may exceed 0.4 footcandle measured at the residential property line. Both readings must be taken after dark at the property line or roadway edge, giving code enforcement a fixed, measurable test rather than a subjective glare standard.

The section also gives the city discretion to limit the hours of operation of outdoor lighting if doing so is deemed necessary to reduce impacts on the surrounding neighborhood, a tool the city can apply to specific sites such as ballfields or drive-through businesses near residences. Sec. 129-2(d) reinforces the limit with a separate glare rule: direct or sky-reflected glare from floodlights or high-temperature processes like combustion or welding cannot be directed onto any adjoining property, flickering or flashing lights are barred outright, and a fixture cannot be sited so its light source or reflected image is directly viewable from off the site.

Compliance is verified through the light distribution plan required under Sec. 129-2(f) for new or substantially expanded commercial, industrial, or multifamily developments, which must show projected footcandle levels at the property boundaries.
