South Gate Municipal Code Chapter 5.33 (Tree Preservation and Protection) requires a permit from the Director of Public Works before any person may plant, remove, relocate, damage, excessively prune, cut, or encroach into the protected zone of any 'public tree.' A 'public tree' is broadly defined as any plant normally reaching mature heights of 15 feet or more with one-half or more of its trunk or branches on or above public property — which covers all street/parkway trees lining South Gate's ~15,900 parkway-tree urban forest. Private-property trees are not generally regulated by Chapter 5.33 absent a planning condition.

Altadena FAQ
Can I cut down an oak on my Altadena property?
Only with an Oak Tree Permit from LA County Planning if the oak is ≥8 in diameter at breast height — Section 22.174.040.
South Gate FAQ
Do I need a permit to remove a tree in my own back yard in South Gate?
Chapter 5.33 regulates 'public trees' — trees with one-half or more of the trunk or branches on or above public property (street parkways, parks, civic facilities). A tree fully on your private property is generally outside Chapter 5.33, but if it overhangs the parkway, was required by a planning/landscape condition of approval, or is a parkway tree in front of your house, you must get a permit from the Public Works Director first.
Can I trim the parkway tree in front of my house?
Not without a permit. SGMC 5.33 prohibits any person other than city staff from pruning, cutting, or encroaching into the protected zone of a public tree without first obtaining a permit from the Director of Public Works. Even minor 'excessive pruning' triggers the civil penalty (full tree restitution value plus install cost).
What if the tree is damaging my sidewalk or sewer line?
Contact South Gate Public Works (323) 563-9500. The city maintains a tree-service schedule for its ~17,500-tree urban forest and can inspect and authorize remediation. Do not remove or root-prune unilaterally — that triggers the Chapter 5.33 civil penalty and possible misdemeanor charge.
