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 Tulare County has 226 FIRM panels, the newest effective December 2012; 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 Tulare 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 Tulare lot shows the same lines the county assessor draws. Tulare County covers about 3,087,294 acres of land and 9,209 acres of water.
Mapped lines are approximate. The Tulare County assessor keeps the parcel record (Tulare County website); a licensed surveyor sets the true corners.
Zoning
Tulare County zones its unincorporated land, and Visalia, Tulare, Porterville 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 Tulare 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.
Septic and soil
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Tulare County is soil survey area CA659, Tulare County, Western Part, California, last updated September 2026, on Web Soil Survey.
