Frequently asked about Brooklyn landlord data

How many landlords does MetroDeeds track in Brooklyn?

MetroDeeds tracks 871 residential property operators with at least one building registered in Brooklyn. The cohort is filtered to named operators (with personal HPD accountability) holding two or more properties citywide. Multi-borough operators count toward this total if any of their portfolio sits inside Brooklyn; the same operator can also appear on other borough hub pages. Single-family owner-occupants and one-off LLCs are filtered out by the manager-suppression rules.

Who is the worst landlord in Brooklyn?

By open HPD violation count, the highest-distress operator with a Brooklyn presence today is MOSHE PILLER, carrying 76,468 open code violations across 60 buildings (distress score 98 of 100). The full distress ranking is recomputed nightly and the operator’s individual profile breaks down which violations are Class A, B, or C. MOSHE PILLER may operate in multiple boroughs — this list filters by Brooklyn property presence, not borough-of-residence.

How many HPD violations are open in Brooklyn?

Across the 871 tracked operators with a Brooklyn presence, MetroDeeds counts 2,892,618 open HPD code violations citywide as of the most recent nightly compute. This figure rolls up Class A (non-hazardous), Class B (hazardous), and Class C (immediately hazardous) violations and reflects whole-portfolio counts — multi-borough operators contribute their full violation total here. The HPD violation source dataset publishes daily on NYC Open Data; the borough hub refreshes every six hours.

How often is Brooklyn data updated?

MetroDeeds runs a full nightly compute job at 4 AM ET that refreshes every operator’s violation count, property count, distress score, last acquisition date, and flag set. The borough hub page reads from that cache and re-renders every six hours via Next.js incremental static regeneration. Changes to underlying NYC Open Data (HPD violations, ACRIS deeds, OCA evictions, 311 complaints) flow through within 1–2 nightly runs of source-data publication.

Can I download Brooklyn landlord data?

Free MetroDeeds accounts get 3 full due-diligence reports — no credit card required — and can browse the full Brooklyn operator list at any time. Scout+ ($49.99/mo) unlocks unfiltered deed history, $/SF context, and full owner-of-record names. Pro ($149.99/mo) adds bulk CSV export of operator and deed data plus PDF portfolio reports. Enterprise ($499.99/mo) adds programmatic API access for automated workflows.

What's the difference between Brooklyn HPD violations and DOB violations?

HPD (Department of Housing Preservation and Development) issues violations for tenant-facing housing-quality issues — heat, hot water, mold, leaks, pests, locks, peeling paint, broken windows. DOB (Department of Buildings) issues violations for construction-code and safety issues — illegal alterations, unsafe scaffolding, unregistered work, expired permits. MetroDeeds’ distress score weighs HPD violations because they reflect tenant-experienced conditions; DOB violations are tracked separately on each operator’s profile page under the Construction & Permits section.
