Data Sources

Building facts (year built, units, floors, zoning, lot area, owner of record) are sourced from NYC PLUTO (Department of City Planning). Deed transfers and consideration amounts come from NYC ACRIS (Department of Finance); NYC ACRIS coverage extends back to 1966, so an absence in the 5-year window typically means the BBL has not transacted recently or the most recent recorded document is not a DEED type. Open housing-maintenance violations are pulled daily from the NYC HPD violations feed. Assessed values are published by the NYC Department of Finance; building class is assigned by Finance and recorded in PLUTO. PLUTO ownership reflects the most recent Department of Finance refresh; for buildings transferred within the last 6 months, MetroDeeds prefers the deed grantee as the current owner.
