San Jose FAQ
Can I leave my Christmas lights up all year in San Jose?
Technically yes if unlit, but running them year-round loses the seasonal exemption and turns them into permanent outdoor lighting subject to fixture, shielding, and Kelvin standards. Most homeowners take displays down by mid-January.
Are synchronized music light shows legal?
Yes, but audio output is regulated under SJMC noise rules. Late-night runs after 10 p.m. can violate quiet hours and amplified-sound limits. Crowds blocking the public street may also draw nuisance enforcement from SJPD.
Do I need a permit for an inflatable lawn display?
No permit is needed for residential seasonal displays on private property. The display must not block driver sightlines, encroach into the public right of way, or interfere with utility access. HOAs may impose their own rules.
Sunnyvale FAQ
Can I leave holiday lights up year-round in unincorporated Santa Clara County?
You can, but once the seasonal window ends, the lights must meet the County's permanent-fixture standards on color temperature, shielding, and brightness. Most consumer string lighting passes the brightness check easily.
Do animated drive-by displays need a permit?
Residential displays do not need a permit, but if traffic creates safety problems the County can require a traffic-management plan, additional off-street parking, or limit display hours under the public-nuisance authority.
