Method
How it was counted.
Source: Maricopa County Assessor's Office parcels (mcassessor.maricopa.gov), the county assessor's own parcel data. Counted 2026-10-06 with Tracer’s Request Data filters, government owners and mailing addresses abroad left out.
A complete record has an owner name, a property address that starts with a house number, and a mailing street with a 5-digit ZIP. Out-of-state reads the mailing ZIP. Company owners are a text match on the owner name (LLC, INC, CORP, LP, TRUST, PROPERTIES, HOLDINGS or INVESTMENTS). Owners of 3+ group the exact owner name. “Share complete” is the county’s complete records against every row we store for it.
There’s no single-family column: Maricopa County's parcels in this data carry no property type yet. Arizona’s data here carries no homestead flag, so no column says whether the owner lives in the property.
