Phoenix Teardown Index
13,691 Phoenix-area teardown-profile parcels
We scanned all 1,742,670 Maricopa County parcels and found
13,691 with a teardown profile — land worth far more than the aging building
on it, the structural signature of a redevelopment site. This is a city-by-city
census of every one, not a sample. Built from public assessor records, fully
reproducible, updated 2026-06-26.

Methodology — reproducible from public data
Data vintage: 2026-06-26 · Source: Maricopa County Assessor (public records).
Maricopa County parcels where the land value is more than 70% of total assessed value (land + improvement) and the structure was built between year 1 and 1979 — i.e. an aging building on land worth far more than the house, the structural profile of a teardown/redevelopment candidate. Reproducible from public Maricopa County Assessor data.
Exact rule: market = 'Maricopa' AND land_value / (land_value + improvement_value) > 0.70 AND year_built BETWEEN 1 AND 1979.
Every figure on this page is a city-level aggregate of public records — no individual parcels, addresses, or owners are published. The parcel count, median build year, and land-share columns reproduce directly from the public Maricopa County Assessor data using the rule above. The Opportunity-Zone column additionally joins each parcel to the public U.S. Treasury Opportunity Zone census-tract designations; the out-of-state column uses the assessor's owner mailing-address state. All three sources are public, so every figure remains independently reproducible.
This census is a deliberately strict structural profile (land worth far more than an aging building). Our calibrated redevelopment signal flags 30,517 Maricopa parcels as teardown candidates — broader, because it also catches partial-teardown / value-add cases the strict land-share rule misses. That signal is not just a heuristic: on a leakage-safe retrospective backtest it concentrates real demolitions and new-SFR permits at 2.95× the base rate in its top decile.
