Antioch FAQ
Do I need a permit to remove a dead oak tree?
Yes, but dead/hazardous-tree permits are typically expedited and may be free. Document the condition with photos and an ISA-certified arborist report before removal to avoid enforcement.
Can I prune a protected tree without a permit?
Routine pruning is allowed, but removal of more than 25 percent of the canopy or major scaffold limbs requires a permit and arborist oversight to avoid effectively killing the tree.
