Integration details
Description
Look up US property by street address or parcel number. For each property, L3R returns: 1. What's there: property type, number of buildings, floors, year built, and the official name when it has one. 2. Which parcel: the county parcel number and a stable L3R property key. 3. Where it is: location, plus Census tract, place, and county with 2020–2024 survey figures (population, housing, tenure, income, home value, rent). Coverage parcel numbers for about 124 million properties in 2,216 / 3,222 US counties; Census figures for all 50 states, DC, and Puerto Rico. Building facts come from open public sources, so they are held for many properties, but not all. Free and read-only, with no account needed. One address per call. L3R never returns owners, values, sales, or parcel outlines. Built by L3R, real property intelligence. For municipal code, permits, and rights, see Athena at 3drights.com.
