Costa Mesa FAQ

Can I trim my own oak tree?

Routine pruning of healthy trees on your own parcel is generally allowed, but heavy pruning into the main canopy or root zone may trigger county review on hillside lots.

What if a protected tree is dying?

Document the condition with an arborist report and contact OC Planning. Hazardous tree removal is typically permitted but may still require replacement planting.
