About LandBrief

LandBrief is a free reference site for United States parcel records: who owns a piece of land, how big it is, what the county assesses it at, and where it sits. The site currently publishes more than 85 million parcel records compiled from more than 1,900 county datasets across 45 states, browsable by state, county, city, and owner. The exact, current figures are on the data sources page, which is generated from the same database that serves every other page here.

Why this site exists

Parcel records are public, but they are scattered across thousands of county websites running different software, with different search forms, different export formats, and in many cases no way to browse at all — you can look up a parcel you already know, but not see a county whole. LandBrief compiles county assessor and GIS records into one place with one consistent structure, so that a rancher can see who holds the land around theirs, a buyer can see what a county actually looks like parcel by parcel, and a researcher or journalist can ask questions like “who are the largest landowners in this county?” and get an answer with sources attached.

Who runs it

LandBrief is built and operated by Dynamo Foundry LLC, a company that works with geospatial and public-records data. The site is free to use and is supported by advertising. Advertisers have no influence over the records shown, the rankings computed, or anything else on a page — the editorial policy spells that out.

What LandBrief is not

LandBrief is a compilation of public records, not the official record. Counties amend their rolls continuously, and every dataset here carries the date of the assessor roll it came from — some counties deliver new data often, others rarely. Before acting on anything you find here — a purchase, a boundary question, a legal matter — verify it with the county assessor or recorder, whose office holds the authoritative version. How each figure on this site is derived, including the cases where we withhold a county’s own numbers because they fail basic sanity checks, is documented on the methodology page.

Questions, corrections, and record-removal requests all go through the contact page. How we handle personal information is covered by the privacy policy.
