Despite its dark Trinity Alps skies, unincorporated Trinity County has no countywide dark-sky ordinance setting fixture-shielding or color-temperature standards for general outdoor lighting. The zoning code's glare performance standard bars direct or reflected glare visible across a property line, and shielded, downcast lighting is required for specific uses such as cannabis, agritourism, and telecommunications facilities.
Unincorporated Trinity County has no dedicated light-trespass ordinance for ordinary residential lighting, but its zoning code glare standard effectively limits spillover by barring direct or reflected glare visible across a property line.
