CAL FIRE's 100-foot defensible-space guidance stops at the property line
CAL FIRE’s public guidance points many fire-risk homes toward a 100-foot defensible-space zone around a structure. The practical wording matters: keep reducing potential fuel within 100 feet or to the property line.
So yes, the work can extend well past the patio. But no, that does not mean you can clear a neighbor’s land without permission. Start with your own property, then check local fire rules if the risk crosses fences.
