Lake Havasu City, AZ Outdoor Lighting: Light Trespass & Shielding (2026)

Beyond the bare-bulb, downward-direction, and recessed-fixture rules of Section 14.04.05.C.2.b, the code publishes side-by-side illustrations captioned "Does not comply, Light trespass" and "Complies, No light trespass" so applicants and inspectors can compare a noncompliant spill of light onto a neighboring lot against a shielded fixture that keeps illumination on-site. Fixtures on automobile service station and convenience store canopies get a related rule in division C.2.c: the light source may not protrude downward beyond the canopy ceiling, the same trespass concern applied to a common commercial fixture type.

All of this sits under the shielding standard in division C.2.a, which forces any source over 375 lumens into an IESNA full cut-off fixture with a cutoff angle no steeper than 90 degrees specifically to minimize glare and unnecessary diffusion onto adjacent property. Division B.1 adds a timing backstop for the same nuisance: outdoor facilities normally expected to close by midnight may not stay illuminated after midnight unless another provision allows it. The shielding and trespass rules apply citywide except for the narrow exceptions in division A.2 for street lighting, temporary construction or event lighting, and lighting regulated by the Federal Aviation Administration.
