Navajo County, AZ Outdoor Lighting: Billboard Lighting (2026)

Section 1706 sets the full permit standard for Outdoor Advertising Signs (billboards) along the unincorporated county's highways, and item 1(i) folds lighting directly into that permit: any light source illuminating the billboard face has to be mounted at the top of the structure rather than ground-mounted floodlighting from below, and it has to be shielded in compliance with Navajo County's own lighting regulations under Article 18, plus whatever additional restriction ADOT imposes where the billboard sits in ADOT-regulated right-of-way. 3, which requires outdoor fixtures to be aimed and shielded so illumination stays within the property boundary rather than spilling onto the highway or a neighboring parcel, and Section 1803's cap on unshielded illumination of a structure to small fixtures only.

The billboard-specific lighting requirement sits alongside the sign's other maintenance duty in item 1(j): billboards must be kept to a professional standard of structural integrity and appearance. Both duties feed the same enforcement mechanism in Section 1706's closing paragraph, which lets the Director recommend the Board of Supervisors revoke a Billboard Permit for any uncured noncompliance, lighting included.
