This is an example program page. I've built pages like this from public records for several health departments and lead programs that bought or are trialing the kit. I'll build one for your area too, at no cost.

You tell us the county, city, or ZIP codes you cover. We pull the public records: the year every home was built from the county assessor, Census figures on housing age and poverty, and HUD's lists of federally assisted housing. Older homes are far more likely to have lead paint, so we rank each neighborhood and each home by when it was built, using the model I published in AGU GeoHealth in October 2026 (how the model works).

You get a page like this one for your area, a map down to the individual house where the county publishes build years, a ranked address list sent to your staff directly and not published, printable handouts, and a few free kits to try. All of it is free, with no purchase required.

Lead risk in Philadelphia, building by building.

This is a map of lead-paint risk taken all the way down to individual homes, here in North Philadelphia. Each dot is a real property from the City of Philadelphia's own assessment records, colored by the decade it was built. Older homes are far more likely to contain lead paint, so the age of a building is a strong first guess at where the hazards are.

Built from the City of Philadelphia OPA Properties Public dataset (OpenDataPhilly). Year built is an assessor value, mostly estimated, used for era bucketing. Lead-paint-by-era rates from the HUD National Survey of Lead and Allergens in Housing. This is a screening tool that shows where to look first, not a diagnosis of any specific home.
