Summary
Linn County has no blanket dark-sky ordinance, but its zoning code requires off-street parking lighting to be shielded and aimed downward and away from neighboring homes and public streets so it doesn't become a nuisance.

Full Breakdown
Linn County Code § 107-93(e)(5)g requires that lighting used to illuminate off-street parking areas be directed downward and away from residential properties and public streets so it doesn't create a nuisance: a shielding standard, not a lumens cap or curfew. Institutional facilities like school transportation and maintenance centers carry a stricter rule elsewhere in the code requiring full-cutoff fixtures with no upward light spill. There's no countywide dark-sky ordinance covering all outdoor lighting on private residential property in unincorporated Linn County; this section reaches parking-area lighting specifically.
Violations & Fines
Off-street parking lighting that spills glare onto neighboring homes or public streets instead of shining downward is a code violation the county can require the property owner to correct.
