San Jose FAQ
Can I trim my neighbor oak branches hanging over my yard?
California common law allows trimming branches back to the property line at your expense, without damaging tree health. For heritage oaks, excessive pruning could trigger violation even on your own side.
Do I need a permit to trim dead branches?
No. Dead, diseased, and hazardous branch removal is generally exempt. Document the hazard with photos, and consider hiring a certified arborist for heritage trees to avoid disputes.

Routine maintenance pruning is allowed, but if the tree meets heritage size and you remove over 25 percent of the canopy you need a permit.
Who trims the street tree in front of my house?
