Summary

In unincorporated Los Angeles County land inside a mapped Significant Ecological Area, removing, pruning past 25% of foliage, or encroaching on a tree from the County's SEA Protected Tree List requires a Protected Tree Permit; taking more than two or any Heritage Tree needs a full SEA Conditional Use Permit.

City-specific rules exist: Inglewood, Los Angeles, El Monte, Pasadena, Palmdale, Pomona, and Glendale have their own protected tree species rules that differ from Los Angeles County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Full Breakdown

LA County Code Chapter 22.102 regulates development inside mapped Significant Ecological Areas (SEAs) within the unincorporated county. A Protected Tree Permit, reviewed by Regional Planning, covers pruning over two inches or 25% of foliage, protected-zone encroachment up to 30%, or removing up to two non-Heritage SEA Protected Trees. Removing more than two, or any tree designated a Heritage Tree, requires a full SEA Conditional Use Permit with a public hearing. Removed trees must be replaced with the same native species at a 2:1 ratio, monitored seven years, or funded through the County's Protected Tree Fund. The chapter binds only unincorporated SEA land, not the City of Los Angeles or other cities.

Violations & Fines

Each protected tree cut, damaged, removed, or relocated without a permit is a separate violation under § 22.102.070.H, enforceable as a misdemeanor or civil penalty by Regional Planning and County Counsel.

Frequently Asked Questions

Does this rule apply inside the City of Los Angeles?

What happens if I remove a SEA Protected Tree without a permit?
Each tree cut, damaged, or removed without a Protected Tree Permit or SEA CUP is a separate code violation, enforceable by Regional Planning and County Counsel.
