Official sources and limits (9)
Official identifiers and dated extracts establish a research starting point. They do not replace the current offering plan, management package, contract review, inspection, title search or advice from the buyer’s attorney and other professionals.
- Facts and evidence states checked 2026-09-09; refresh time-sensitive details before publication.
- This minimum profile uses a verified condominium identity and public evidence; unresolved or time-sensitive details are intentionally omitted or qualified.
- ACRIS records the current condominium declaration and maps on February 9, 1995. The older address-matched NYAG filing C810285 was a withdrawn cooperative proposal and is excluded from the condominium identity.
- Labels marked “some/select residences” are unit-level opportunities, not building-wide promises.
- Derived labels follow the research workbook’s stated official-data thresholds and limitations.
- Staffing, amenity access and operating details should be confirmed with current management.
- Residential and total condominium-unit counts can differ when commercial, parking or storage units are separately designated.
