Do I need a permit to cut down a tree?

---

Registered heritage trees, trees that provide land stability, are of a protected species or size, or provide visual screening/and or privacy are subject to tree removal permits. Each tree removal permit is subject to individual consideration and approved or denied on a case by case basis by the Planning Division. Some factors used to determine tree removal approval include hazardous situations, number of trees on a property, damage to existing structures, and reasonable development. Prior to removing any tree on your property, you are advised to contact the Planning Division at (925) 674-7205 to verify your tree does not require a removal permit.

Do my neighbors need a tree permit to remove a tree? When do they need a permit and what is the process and timeline involved?

---

The Tree Protection and Preservation Ordinance (Chapter 816-6) defines a protected tree. A tree is either protected or not protected based on its characteristics (e.g. trunk size, species) and the characteristics of the property on which it is located. The Ordinance requires that the property owner obtain a tree permit from the county before trenching, grading or filling within the dripline of any protected tree or before cutting down, destroying, trimming by topping or removal of any protected tree.
