Los Angeles County
South Gate is a dense urban LA County city and is NOT within a Very High Fire Hazard Severity Zone, so the 100-foot defensible space rule of Public Resources Code §4291 does not apply. However, the California Fire Code §304 (adopted via South Gate Municipal Code Title 9) prohibits accumulation of combustible vegetation and rubbish on private property, and South Gate enforces weed abatement and property maintenance under its nuisance/property maintenance authority.

Altadena FAQ
How much brush clearance is required in Altadena?
200 feet of defensible space around any structure if you are in a Very High Fire Hazard Severity Zone, per LA County Fire and California PRC 4291.
South Gate FAQ
Do I need 100 feet of defensible space around my home in South Gate?
No. PRC 4291's 100-foot defensible space rule applies only to State Responsibility Area land and to Very High Fire Hazard Severity Zones. South Gate's urban footprint is not in a VHFHSZ, so the 100-foot rule does not apply. You must still keep dry weeds, vines, and combustible debris off your lot under California Fire Code §304.
What happens if my vacant lot gets overgrown?
Code Enforcement will issue a notice giving you a deadline to abate. If you don't comply, the city can contract the abatement and bill you, with the amount becoming a lien on the property under Government Code §38773.5.
Are tree-trimming standards regulated under fire code?
California Fire Code §304.1.2 authorizes removal of vegetation that creates a fire hazard, but routine tree trimming in South Gate falls under Title 11 zoning and parkway tree rules, not fire code.
