Molluso Holdings
Hazard, tax, flood and environmental data resolved to the parcel, straight from the county and federal systems of record. Take it as an API, or as a finished report under your own brand.
The disclosure industry runs on a small number of wholesale data vendors, and most of the price on a property report is the cost of that file rather than the cost of producing the report. Everybody buys the same data, so nobody has an advantage.
We built the layer underneath instead. County secured rolls, CDIAC filings, state hazard layers and federal environmental databases, assembled parcel by parcel and reconciled against each other. That is unglamorous work, and it is the whole moat.
Two modes on every hazard
Centroid and polygon
A large or irregular parcel can sit with its centroid outside a zone while most of its footprint is inside. Both results come back on every call, because that disagreement is where defensibility lives.
Priced per parcel
Not per report
Repeat lookups on the same parcel inside the same month are free. In a business where a property gets pulled more than once per transaction, that changes the real cost more than the headline rate does.
Product architecture
Four report products, one engine underneath. Same parcel resolution, same sources, packaged for whoever is buying.
California natural hazard disclosure
The six statutory hazards under Civil Code 1103, the supplemental tax notice, and the full assessment picture. Delivered as a substituted disclosure or as raw data under your own brand.
Determination and certification
FEMA NFHL at the parcel polygon, not the centroid alone. Built for lenders who need a defensible determination on volume and a turnaround measured in seconds.
Ownership, tax and assessment
Owner of record, assessed values, the full secured roll breakdown including Mello Roos, 1915 Act assessments and PACE liens, reconciled against the county source.
Environmental and proximity
Seven federal and state environmental databases, each queried at its own statutory search radius, plus the proximity layers a commercial buyer asks about.
NHDdata is the California NHD product line under the umbrella. Same team, same engine, same reports.
No resold aggregate file sitting between us and the source. Every layer traces to the agency that publishes it.
Statutory hazard layers are statewide in California. Parcel level Mello Roos coverage is deepest where county ingestion is complete and expands continuously. We will show you the real coverage map for your footprint rather than claim blanket coverage.
For platforms and lenders
A metered REST API with bearer key auth, per customer pricing, prepaid credits, idempotency keys, request tracing and webhook delivery. Or a white labelled report that goes out under your name with your logo on the cover.
If you already produce property reports, this is the layer underneath them. Your customer never knows we exist.
Request accessEndpoints
Priced per parcel per month, with repeat lookups on the same parcel free inside the month. Volume pricing on request.
Send a county and a handful of APNs. We will run them and send back what comes out, next to whatever you use today.
