Summary
Detroit caps light spillover from non-residential and commercial lighting, including security lighting, at 0.5 foot-candles on neighboring property lines and bans strobe lights visible from adjacent lots under the zoning code's performance standards.
Glare is illumination that is caused by all types of lighting and from high temperature processes such as welding or metallurgical refining. Glare may not directly, or indirectly from reflection, cause illumination on other properties that is in excess of a measurement of 0.5 foot-candles of light; ... Strobe lights that are visible from another property are not allowed.

Full Breakdown
Detroit City Code § 50-14-590 sets a citywide glare standard: light from any source, including security lighting, may not cause illumination on a neighboring property in excess of 0.5 foot-candles, measured at the property line or at habitable levels of a building. Strobe lights visible from another property are banned outright. The standard applies to non-residential uses in every zoning district under Article XIV's Operational Performance Standards. Separately, § 50-14-236 requires off-street parking lot lighting to be shielded away from adjoining residential lots, and § 50-12-401 requires urban-farm lighting to stay within the property line. The Buildings, Safety Engineering and Environmental Department enforces compliance.
Violations & Fines
Violations are blight infractions enforced by BSEED; each uncorrected day counts as a separate violation. Unpermitted or noncompliant land uses draw escalating civil fines, generally $250 to $1,000 per offense, under Sec. 50-5-24 through 50-5-28.
