Tree removal permit rules in Los Angeles County, CA — sometimes called heritage tree, protected tree, or street tree ordinances — list which trees require a permit before you can cut them down.
LA County Code Title 22, Chapter 22.174 protects oak trees in unincorporated areas. Removing, damaging, or encroaching on any oak tree 8 inches or more in diameter requires an Oak Tree Permit from the Department of Regional Planning.
Chapter 22.174 of the LA County Zoning Code establishes the Oak Tree Permit process for unincorporated areas. No person shall cut, destroy, remove, relocate, inflict damage, or encroach into the protected zone of any tree of the oak genus which is 25 inches or more in circumference (8 inches in diameter) measured at 4.5 feet above mean natural grade. For multi-trunk oaks, combined circumference of any two trunks must be at least 38 inches (12 inches diameter). An Oak Tree Permit application is reviewed by the Department of Regional Planning. Conditions typically include replacement tree planting at ratios of 2:1 or greater, tree protection plans during construction, and bonding for replacement monitoring. Approved permits expire within one year if not used. Heritage oaks receive additional protections.
Removal without permit is a misdemeanor. Fines up to $1,000 per tree and/or six months in jail. Replacement tree planting of 10:1 or more may be ordered. Civil penalties for environmental damage may be imposed separately.
