Protected-tree rules
Every Alameda County city with a tree ordinance protects trees above a size or species threshold, which means neither neighbor can remove, and often cannot heavily prune, the tree in dispute without a permit, whatever they agree between themselves. Thresholds, species lists, measurement rules, fees and penalties are catalogued city by city on Urban Forestry Guide, and the report cites the rule that applies to your tree.
What disputes look like here
East Bay hills disputes are view disputes and fire-fuel disputes in the same yard: Monterey pines, eucalyptus and acacias blocking Bay views in Oakland and Berkeley, and the same trees as ladder fuel in the wildland-urban interface. Oakland's view ordinance exempts coast live oak and bay laurel; Berkeley protects only coast live oak on private land. Flatland disputes are the usual roots, fences and sewer laterals, and both Oakland and Berkeley have private sewer lateral ordinances that shape who pays.
