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.
Fremont FAQ
Can I trim my own non-heritage tree any time?
Yes, routine maintenance pruning (up to 25 percent of the canopy, shaping, deadwood) on non-heritage trees needs no permit. Schedule major work in late fall or winter to minimize stress and avoid bird nesting season.
What if a neighbor tree drops leaves or fruit on my yard?
Leaf and fruit drop is not actionable in California. You can trim overhanging branches to the property line at your cost. Damaging the tree can expose you to treble damages under Civil Code 3346.
