Berkeley FAQ
Can I prune my neighbor's tree overhanging my yard?
Under California law you may prune to the property line without permit, but you cannot damage the tree's health. For protected species, seek city guidance first to avoid liability.
Do I need a permit for fire-safety pruning?
No permit is needed for pruning required by PRC 4291 defensible space, even on protected trees, provided the work is limited to hazard reduction and done by a qualified arborist.
Oakland FAQ
Can I trim my own backyard oak without a permit?
Light maintenance pruning is allowed, but removing more than 25 percent of the live crown or any structural limb on a coast live oak 4 inches or larger requires a Tree Removal Permit.
What about a dead or dangerous tree?
Dead trees and imminent hazards can be removed without prior permit, but the owner must notify Tree Services within 48 hours and provide photos or an arborist statement documenting the condition.
