Built for the whole United States · launching in Phoenix

Open access to hidden land value, parcel by parcel.

LotAtlas is building an atlas of every parcel in the United States — reading the public record on assessments, sales, ownership, zoning, and incentives to surface the sites that are underbuilt, mispriced, incentive-qualified, or changing. County by county, starting with Maricopa County (Phoenix).

You're on the list. We'll write when there's something real to show.

What we track

Every screen ends in a parcel list

Not dashboards — candidates. Each screen reads the public record one way and comes back as a ranked list of specific parcels.

Four screens: triple-stack incentive parcels, faith-housing sites, solar roof candidates, and legalization windows, each producing a parcel list

Four ownership diagrams: same mailing address across parcels, adjacent control, absentee ownership, and concentrated landlords

Four capacity diagrams: ADU room to build, soft sites built below their zoning envelope, stacked incentives, and multiple kinds of upside

Four before-and-after maps: a recent sale, new construction, a demolition signal, and a zoning or assessment shift

Four maps: finding hidden land value on a block, ownership patterns pointing to one owner, spotting assessment gaps, and tracking what changed

Four assessment diagrams: over-assessed parcels versus nearby sales, ranked appeal candidates, land versus improvement value, and tax-basis divergence patterns

Coverage

The whole USA. County by county.

LotAtlas is built for the entire United States — every county publishes the records we read. We're rolling it out one county at a time, and the first is Maricopa County (Phoenix): one of the fastest-growing metros in the country and one of the best-kept public parcel rolls anywhere.

Growth this fast leaves the record full of lag: lots built decades below what zoning now allows, assessments trailing a moving market, incentive boundaries nobody has screened parcel by parcel. LotAtlas reads all of it, for every parcel in the county, and keeps reading as it changes.

More counties follow in launch order. Maricopa is where we prove it.
