About Vacant Property Indicators
Vacant Property Indicators is the City of Philadelphia's published view of which parcels are likely vacant. It ships as three companion ArcGIS Feature Services. We treat the building layer as the canonical dataset for the catalog, and consume the other two directly in stories.
Three layers
- Vacant_Indicators_Bldg — ~8,146 polygons. One row per vacant building. OPA/LNI keyed, council district, zoning base district, zip. FeatureServer →
- Vacant_Indicators_Land — vacant lots. Same schema shape as the building layer. FeatureServer →
- Vacant_Block_Percent_Combined — ~22,619 census
block polygons. Each carries
parcelcount,combinedvaccount, andcombinedvacpercentage. The denominator-aware view: how much of the block is vacant, not just how many vacant items sit on it. FeatureServer →
Caveats
"Vacant" here is an indicator inferred from city records (no building permit activity, no
occupancy signal, distressed visual condition, etc), not a confirmed inspection finding.
Records refresh on the date_update column; historical
change is not preserved on the public service. For longitudinal change, pair with L&I complaints
/ violations or external assessment-history snapshots.
