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

Section 27-2592(g)(1) sets the town's baseline light trespass standard: off-site light spillage is measured against Table 1 of the lighting regulations, and the maximum footcandle spilled onto another property, including streets, rights-of-way, road easements and alleys, cannot exceed 0.3 footcandle. Section 27-2592(g)(2) tightens that standard for residential neighbors: no off-site light spillage is permitted at all when a residential use sits next to another residential use, and where a residential use spills light onto a nonresidential property, the maximum cannot exceed the minimum footcandle requirement listed for that adjacent lighting zone in Table 1.

Compliance is verified through the photometric plan process in section 27-2592(e): every development application must submit a lighting plan calculated on a ten-foot by ten-foot grid, and section 27-2592(h) sets the field measurement method, reading the light meter at ground level with the light source on, then off, and comparing the difference against the estimated light loss factor of the fixture. Because the off-site cap works from Table 1's lighting zones, an office parking lot bordering a residential lot has to hold its property-line footcandle at or below the stricter residential ceiling, not the higher nonresidential maximum that applies elsewhere on the same site. Section 27-2592(i) also requires developments to keep open parking lots and access areas lit at no less than 50 percent of the Table 1 requirement from dusk to dawn or outside normal business hours, even as the spillage cap keeps that light from crossing onto the neighbor's land.
