Security Light Shielding: San Jose vs Sunnyvale

My neighbor's floodlight shines into my San Jose bedroom; what can I do?

First ask them to shield or aim the fixture downward. If unresolved, file a Code Enforcement complaint at sanjoseca.gov/codeenforcement. Inspectors verify light trespass, document foot-candles at the property line, and issue corrective notices.

Are motion-activated security lights allowed?

Yes, motion-activated fixtures are encouraged because they limit overall light pollution. They still must be shielded, aimed downward, and not produce excessive trespass. Brief activation by motion is preferred over dusk-to-dawn floodlighting under San Jose lighting standards.

What is special about lighting in East San Jose hills?

Properties near Mt. Hamilton lie in the protective area for Lick Observatory. Astronomers need dark skies, so the county and city encourage low-Kelvin amber LEDs, full-cutoff fixtures, and curfews on outdoor lighting after a set evening hour.

Can I install a bright LED floodlight aimed at my back yard?

Yes if it is shielded so the light source is not visible from the property line and does not exceed the County's lumen limits. Aim must be downward, and motion-sensor activation is strongly preferred.

Are existing unshielded security lights grandfathered?

Existing fixtures may continue until they fail or are replaced, but neighbors can still file a light-trespass complaint under the County nuisance code if the fixture causes documented glare across the property line.
