CountyTaxDatabase
For NHD providers

The Mello-Roos data straight from the clerks who issue it.

California Tax Data sells data at $25–35 per report. We undercut by ~95% — and our data is fresher because it comes directly from the municipality, the moment the clerk uploads. One API call per parcel. Authoritative.
