Clark County requires outdoor lights, except seasonal holiday lights, to be directed or shielded to minimize glare visible from streets, nearby dwellings, and above the fixtures. This shielding standard applies across residential and rural zoning districts in the county code. The county has no separate formal dark-sky ordinance.
The county's zoning district standards (for example CCC 40.210.020 for rural districts) require that outdoor lights, except seasonal holiday lights, be directed or shielded to minimize glare visible from streets, nearby dwellings, and above the fixtures. The 'above the fixtures' language limits uplight and light pollution, functioning as the county's dark-sky-style rule. Illuminated signs face parallel limits under CCC 40.310.010 and must not be a nuisance to nearby residences. Clark County has not adopted a standalone International Dark-Sky ordinance, so this shielding requirement in the Unified Development Code is the operative standard for reducing skyglow.
Unshielded outdoor lighting that casts glare onto streets, neighboring homes, or upward violates the district lighting standard and can be addressed through Community Development code enforcement.
