Castaic FAQ
Do I need a permit to remove a tree in LA County?
Only for protected oak trees (native oaks 8+ inches in trunk diameter). Non-oak trees on private property generally do not require a permit. Contact the Department of Regional Planning at (213) 974-6411 to verify your tree's status.
Can I remove a dead or dangerous oak tree without a permit?
Emergency removal of an immediately hazardous tree is allowed but you must provide after-the-fact documentation (photos, arborist report) to the Department of Regional Planning within 5 days.
What if I want to build where an oak tree is?
The department will review whether the project can be redesigned to preserve the tree. If removal is the only option, expect replacement planting requirements (2:1 to 10:1 ratio), an arborist report, and a monitoring period.
Los Angeles FAQ
When do I need a permit to remove a tree?
When trunk diameter exceeds the threshold (typically 6 to 12 inches). Check Los Angeles tree ordinance for exact size.
