How CityLens ranks and qualifies parcelsView methodology and limitationsHide methodology
Source records
Current parcel facts combine NYC PLUTO (including E-designations and restrictive declarations), ACRIS ownership, DOB project activity, LPC constraints, and available CityLens aerial-change observations. Source dates remain visible on every parcel.

Archived snapshots teach the order; current official facts are scored at inference. The 2024→2025 result describes the selected rolling procedure; not this final refit's current hit rate. The current list reserves 250 qualified leads per borough before merit-fill.
Historical benchmark hit rate
In the historical 2024→2025 benchmark, 34 of the top 100 received a DOB new-building filing (34%; observed 95% interval 25.5–43.7%), and 104 of the top 1000 did so (10.4%; observed 95% interval 8.7–12.4%), versus a 0.124% eligible-population base rate. These outcomes have been inspected during model development and are not an independent current-accuracy estimate. The ranges quantify fixed-list outcome uncertainty only; they do not include model selection, spatial dependence, dataset shift, or current acquisition outcomes.
Live cohort monitor overdue
Evidence has not advanced for 9 days; the weekly freshness limit is 8 days. The last accepted observation date is Oct 26, 2026.
Historical validation remains available, but live cohort metrics are stale and must not be treated as current accuracy. Investigate the monitor or official DOB source before relying on them.
Required diligence
Administrative lots, active projects, stale ownership, zoning overlays, environmental-designation requirements, tenancy, and site conditions can invalidate a lead. Verify official records and professional advice before outreach or underwriting.
