These facts are for the listing's map point, which can sit off the lot. A zone line can also cross a lot, and agencies revise their maps. In cities, the fire zone line follows the State Fire Marshal's 2025 map; each city adopts its own map and may add areas. These lines are not a Natural Hazard Disclosure. Check the official maps and the seller's disclosures before you rely on them.
