Towns in Kings County: Hanford, Lemoore, Corcoran.
Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA's countywide study for Kings County has 64 FIRM panels, the newest effective September 2015; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Kings house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the California county parcel layers (each county publishes its own), so a Kings lot shows the same lines the county assessor draws. Kings County covers about 890,222 acres of land and 782 acres of water.
Mapped lines are approximate. The Kings County assessor keeps the parcel record (Kings County website); a licensed surveyor sets the true corners.
Zoning
Kings County zones its unincorporated land, and Hanford, Lemoore, Corcoran each zone the land inside their limits. ParcelSheet shows the use the county assessor lists for the lot and links the county planning department for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under California's Planning and Zoning Law (Government Code Title 7, Division 1, starting at section 65000), local governments can allow an accessory dwelling unit on a lot with a house. Whether a Kings lot can add one depends on its district; the county planning department has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
