Dark Sky Rules

Unincorporated Lake County's UDO has no general residential dark-sky ordinance. The only codified downward-shielding standard applies to solar farms, which must shield operational lighting away from adjacent properties and aim it downward. For homes, standards come from your city or town; the county limits commercial-style lighting on home occupations.

Outdoor Lighting and Dark-Sky Standards

Some Restrictions

Light Trespass & Shielding

Unincorporated Lake County's UDO sets no numeric residential light-trespass (foot-candle) limit. Its enforceable trespass-type controls are narrow: solar-farm lighting must be shielded and aimed downward, home occupations may not add commercial-like exterior lighting, and glare mitigation is a screening goal. Persistent glare onto a neighbor is generally a nuisance matter.
