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.

Yes, up to the property line, without harming the tree's health. Giving the neighbor notice first avoids disputes.
