Property Valuation Details

Official physical address of the property.

County name — Harris, Montgomery, Fort Bend, or Waller.

latstringoptional

Latitude in decimal degrees. Skips the internal geocode step when provided.

lonstringoptional

Longitude in decimal degrees. Pair with lat.

floodstringoptional

Set to "0" or "false" to skip the FEMA NFHL per-property flood zone lookup.

multiple_lossstringoptional

Set to "0" or "false" to skip the OpenFEMA NFIP multiple-loss ZIP aggregate.

The history[] array depth varies by CAD — HCAD typically returns 5+ years, while some counties return only the current year. Check isSupported in the response to confirm the county returned live data vs. a mock fallback.
