Sumter County, FL Outdoor Lighting: Light Trespass & Shielding (2026)

Sec. 13-730(b), titled 'Excessive lighting/illumination,' requires that lighting facilities and other uses be arranged and operated so as to prevent direct glare or hazardous interference of any kind to adjoining streets and residentially designated property. The section then draws a specific line for spillover onto a neighbor's land: lighting on any parcel that unnecessarily illuminates another parcel and substantially interferes with the use or enjoyment of that parcel is prohibited outright. The code defines what counts as 'unnecessary' illumination rather than leaving it to interpretation: lighting unnecessarily illuminates another parcel if it clearly exceeds what is needed to satisfy the other lighting requirements of the chapter, such as the foot-candle minimums in Table 730A, or if those same requirements could be met another way that would not substantially interfere with the neighboring property's use or enjoyment.

Because this section sits inside Division 4, 'Safety and Nuisance Standards,' of Article VII of the Land Development Code, a light-trespass complaint is treated as a nuisance issue tied directly to the site design and photometric plan Development Services already reviews for a project under Sec. 13-730(c), so a fixture that was approved as meeting the minimum foot-candle table can still be found in violation if it is aimed or positioned to flood a neighboring residential lot.
