Methodology

Know what you’re looking at.

Our sources, dates and open questions help you use the research with confidence.

123 researched profiles in the current scope · Scope reviewed 2026-09-09 · Snapshot, not live inventory or an official census

01

What the Atlas covers

We research condominium buildings in ZIP codes 11101 and 11109, checking names, alternate addresses and legal phases to avoid duplicate profiles. The Atlas is an evolving building guide, not an official census or live listing feed.

02

Building features and individual homes

Filters use reviewed building-level sources. A balcony, terrace or layout in one residence does not establish a feature in every home. Every profile uses the same building fact fields; residence-specific case studies are presented separately. Confirm current services, fees and the details of the home you are considering.

03

Public records and private documents

Profiles link to dated public records for condominium identity, occupancy, energy, façade and safety filings where matched. A missing match is an unanswered question, not proof that a record does not exist. Private building documents are not published. Transaction-specific document review belongs with the appropriate client relationship and professional advisers.

04

Development & permit watch

A project enters the public watchlist only after we match a condominium offering with a recorded acceptance date in the New York Attorney General database. A building-permit filing alone does not qualify. Permit milestones are shown separately, with sources and review dates; they do not establish current construction progress, completion or availability.

05

What still needs checking

Conflicting counts and dates are withheld or flagged. On-site pool Yes/No labels reflect the team’s building knowledge, reaffirmed October 28, 2026. Other unresolved amenities are labeled Not confirmed. Public sales information is dated and does not replace a current availability check. Public records and historical prices do not establish the value, condition or legal status of a specific home. Your attorney, lender and other advisers confirm the matters relevant to your purchase or sale.
