Port St. Lucie, FL Outdoor Lighting: Light Trespass & Shielding (2026)

Sec. 221(B)(7) requires that wherever artificial outdoor lighting is installed, it be designed so no light source becomes a visible nuisance to adjoining residentially used or zoned property, and so that fixtures shield public streets, highways, and adjacent properties from direct glare or hazardous interference. Citywide, mounting height for outdoor fixtures tops out at 25 feet above grade or pavement. For commercial properties that back up to or sit beside residentially zoned land, the code layers in distance-based height steps: fixtures within 50 feet of the front property line may reach 25 feet if shielded from the street, fixtures in the middle zone drop to a 20-foot cap, and any fixture within 75 feet of the rear property line abutting a residence is capped at just 6 feet or the height of the buffer wall, whichever applies.

All outdoor lighting must use concealed-source, cut-off fixtures where the lens does not project below the fixture's opaque housing, mounted with a zero-degree tilt, and building-mounted fixtures on the rear or sides of buildings next to residential zoning are barred outright except where another ordinance requires them. Ground-mounted flood and spot lights must point toward the building or wall they illuminate rather than outward. Parks and recreational uses are exempt. Existing fixtures installed before the ordinance may keep operating, but any replaced, relocated fixture, or an existing fixture found to glare onto a home or create a traffic hazard, must be shielded or redirected within 90 days of the city's notification.
