What this is, and isn't Zone Zero Check is an independent, AI-assisted informational tool. It is not affiliated with CAL FIRE or the State of California, and it does not satisfy the official Defensible Space Inspection required under Civil Code §1102.19 (AB 38) for a home sale. That documentation comes only from CAL FIRE or your local fire department, request it directly at fire.ca.gov/dspace. Think of this as getting ready before that visit, not a substitute for it.
