How this page is made

Buildings are attributed to this portfolio by the registered managing agent named in their HPD registrations — the entity responsible for day-to-day operations. Ownership LLCs are listed on each building's own page. Every figure is computed mechanically from records published by the City of New York and recomputed weekly, so a portfolio that fixes its buildings improves here. Corrections: support@mice.nyc.
