Scottsdale prohibits light trespass — the spillover of artificial light onto neighboring properties — under its outdoor lighting ordinance (Sections 7.600-7.604). All exterior lighting must be designed and aimed to prevent glare and light intrusion beyond property boundaries.
Scottsdale's outdoor lighting ordinance explicitly addresses light trespass as part of its comprehensive lighting regulations. All exterior lighting must be designed to prevent light from spilling onto adjacent properties or public areas in a manner that creates glare or nuisance. Full cutoff fixtures directed downward are required for all outdoor lights over 3 feet in height. The ordinance references IESNA standards for acceptable light levels at property boundaries. Residential properties may complain about light trespass from commercial properties, street lights, or neighboring residences. Code enforcement investigates light trespass complaints and may require modification or replacement of non-compliant fixtures. The ESLO overlay areas have additional sensitivity to light impacts due to the proximity of natural desert areas and wildlife habitats. Security lighting must also comply with anti-trespass requirements — motion-activated lights are acceptable but must be aimed downward.
Light trespass complaints may result in code enforcement action requiring modification or replacement of offending light fixtures.
