2 rules for unincorporated Lassen County, California.
Verified from official government sources
Despite Lassen County's rural high-desert dark skies, no dedicated dark-sky or outdoor-lighting ordinance was located in the county's Zoning Code (Title 18). There is no county-wide requirement that fixtures be shielded or that lumens be capped. General zoning standards and nuisance law are the main backstops.
Lassen County does not publish a numeric light-trespass standard (no foot-candle limit at the property line). Light spilling onto neighboring property is addressed through general nuisance and code-enforcement principles and, for permitted projects, through conditions of approval - not a dedicated lighting ordinance.
