All reasonable measures shall be taken to ensure that the off-site spillover of light and nightglow are minimized to the greatest extent possible.

Full Breakdown
Section 50-14-418 of the zoning code sets a general illumination standard for all non-residential development in Detroit: reasonable measures must be taken to keep off-site light spillover and nightglow to a minimum. It applies citywide to non-residential uses in residential and business districts, the SD1, SD2, and SD4 special districts, and nonindustrial Planned Developments, per Sections 50-14-411 and 50-14-412. The Planning and Development Department reviews compliance during site plan review; the standard sets no footcandle ceiling, unlike Section 50-14-413's footcandle floors for parking-lot and path lighting.
Violations & Fines
No fixed penalty is specified in this section; enforcement runs through the zoning site plan review and permitting process, and the Planning and Development Department can withhold approval for a lighting plan that fails to minimize spillover.
