Costa Mesa FAQ
Do I need a permit to remove a tree in Costa Mesa?
If the tree was required by a site plan, landscaping condition, or planning approval, yes. You must obtain written approval from the Planning Division and may need an arborist report. Trees not subject to planning conditions may generally be removed without a permit unless they qualify as heritage trees.
Can I trim a tree in the parkway strip in front of my house?
No. Parkway and street trees are city property maintained by the Public Works Department. Do not trim or alter them yourself. Request city tree maintenance by calling Public Works at (714) 754-5343.
What happens if I remove a tree without approval?
You may face code enforcement action requiring replacement trees at a ratio determined by the city. For city-owned street trees, you may be liable for the full replacement cost calculated by ISA valuation methods, which can be very expensive for mature trees.
