NYC Landlord Registry Lead List — HPD Portfolio Contacts

Build bulk landlord and managing-agent contact lead lists from New York City's legally mandated HPD (Housing Preservation & Development) registration data — with the one filter no flat data dump gives you: portfolio size per landlord. Ask for "owners of 5–50 Bronx buildings" and get one clean lead record per unique contact, with their filed business address and a rollup of every building they're registered on.

Every residential building with 3+ units (and many 1–2 unit non-owner-occupied buildings) in NYC must register annually with HPD and name an owner, head officer, and managing agent. That makes this the most complete, legally mandated landlord contact registry in the United States — refreshed continuously on NYC Open Data.

Who it's for

• Property-management companies prospecting owners in a target borough / portfolio band
• Insurance brokers (landlord policies, umbrella, builders risk) building call lists
• Lenders & mortgage brokers targeting multi-building owners for refi outreach
• Contractors, roofers, boiler/elevator service companies selling to building operators
• Proptech sales teams who need decision-maker (HeadOfficer / Agent) leads, not LLC shells
• Real-estate investors & brokers mapping who actually controls a neighborhood

What it does (the transform)

1. Pulls HPD Multiple Dwelling Registrations for your borough/ZIP (dataset tesw-yqqr).
2. Filters to current registrations only — registration end date on/after the dataset's own latest filing date (anchored to the data, not the wall clock; NYC registrations run in annual cycles ending September 1). Set includeExpired: true to keep lapsed registrations too.
3. Pulls the matching HPD Registration Contacts (dataset feu5-w2e2) in batched SoQL IN (...) queries, joined on registrationid.
4. Groups by normalized contact identity — corporation name (case/punctuation normalized) or person first+last name, plus filed business address — so the same management company across 40 buildings becomes ONE lead with buildings_count: 40.
5. Applies your lead filters: contact types, min/max portfolio size, entities only.
6. Outputs leads sorted by portfolio size (largest first), capped at maxResults.

FAQ

How do I get a list of NYC landlords by portfolio size? Set minPortfolioBuildings / maxPortfolioBuildings (e.g. 5–50) and a borough. Portfolio size is computed within the scanned area, so a Bronx run counts Bronx buildings.

Is this data legal to use for outreach? The addresses are business addresses filed under NYC Housing Maintenance Code §27-2097, published as public open data by the City of New York precisely so the public can identify who is responsible for a building. No phone numbers or emails are in the source; this actor republishes only what the city publishes.

Which contact type should I target? HeadOfficer (the decision-maker behind the owning entity) and Agent (the managing agent who buys services day-to-day) are the highest-value roles. CorporateOwner rows give you the owning LLC itself.

Does it include expired registrations? No — by default only current-cycle registrations (end date on/after the dataset's latest filing date). Set includeExpired: true to include lapsed ones, e.g. to prospect owners who fell out of compliance.

Can I run it city-wide? Yes — leave borough empty. Expect a much longer run (~165k current registrations across all five boroughs); borough-by-borough runs are faster and cheaper.

What about new-landlord alerts? A delta mode (only contacts on registrations filed since your last run) is planned for v1.1.

Pricing

Pay-per-result: you're charged only for the lead records actually pushed to the dataset. Runs that match nothing cost only the minimal actor start.

Data sources

• HPD Multiple Dwelling Registrations (tesw-yqqr)
• HPD Registration Contacts (feu5-w2e2)

Both are keyless, public NYC Open Data (Socrata) endpoints maintained by the NYC Department of Housing Preservation & Development.

Actor	What it adds
NYC Distressed Property Leads	Which of those buildings are actually under pressure (violations, liens, evictions)
NYC ACRIS Deed Transfer Intel	Whether the owner has been buying or selling, with price and cash/LLC flags
Parcel Owner Lookup	Address → owner of record for one-off checks

Typical play: build a portfolio-banded contact list here → screen those BBLs for distress → time the outreach against recent ACRIS activity.
