Tree removal permit rules in Los Angeles, CA — sometimes called heritage tree, protected tree, or street tree ordinances — list which trees require a permit before you can cut them down.
LAMC Article 6 (Sections 46.00-46.06) established by Ordinance 177404 requires a permit from the Board of Public Works for removal or relocation of any protected tree. Protected species include California native oaks, Southern California Black Walnut, Western Sycamore, and California Bay measuring 4+ inches cumulative diameter at 4.5 feet above ground.
The Protected Tree Ordinance (Ord. 177404) broadly defines 'removal' to include any act causing tree death, including root damage from grading, application of toxic substances, or equipment compaction within the drip line. Applications require a tree report from a certified arborist or qualified tree expert with 4+ years of experience. Street trees are separately managed by StreetsLA and require a different removal authorization. When removal is permitted, replacement plantings of at least 15-gallon specimens are required, with ratios up to 4:1 determined by the Board of Public Works. Illegal removal can result in building permits being withheld for up to 10 years under LAMC 46.06.
Illegal removal of a protected tree can result in building permits being withheld for up to 10 years (LAMC 46.06). Violators must replace trees at a 4:1 ratio per Board of Public Works policy. Additional penalties include fines and potential misdemeanor charges. Each tree illegally removed constitutes a separate offense.
