A plan shows each building, its owner and the records behind it.

From BlockLot's nightly deal index (2026-10-10): each lot's public records — DOF's roll and sales, PLUTO's zoning, the owners' , liens, permits and violations. A match is a lot worth a look, not a building for sale. Owners are named as on each building's page.

Every number on this page is over the lots fronting the street segments that meet here (DCP's LION node 0014557), on every corner. A corner is named by PAD's corner code for the block's corner lot, in the street grid's own directions (Astoria's grid is turned, so its "north" is not the compass's); where PAD gives none, or two blocks claim one corner, by the corner lot's bearing on the tax map, turned to the same grid.

A mortgage recorded within 90 days after a deed on the same lot is counted as financing that purchase; any other is a refinance — our reading, not ACRIS's. ACRIS files a document against the first lot it names, so a blanket mortgage over several lots counts once. Since 2024-10-10.

around here the property page's comps engine, seeded with this area's census tract and building classes

Class family	Peer set	Sales	Median price	Median $/sq ft	Median $/unit

C (12 lots of class C here)	same census tract, 18 months	••	••	••	••
G (11 lots of class G here)	same census tract, 18 months	••	••	••	—

Each family is compared within its own class letter (a walk-up with walk-ups), on the comps ladder's tract rungs: 18 months, widening to 24 and 36 only when fewer than four sales qualify. Every quality filter applies. Highlighted rows are on this area.

A plan shows each sale, its price, buyer and seller, the lenders and the comparable sales.

Ownership who holds each lot now — the latest deed over a stale roll, the property page's rule

58 owners hold 71 lots · 9 hold more than one (22 lots) · the largest holds 4 (6%)

The three largest owners here own 23 other buildings across the city (their owner groups, as the property page's portfolio card counts them).

A plan shows which lots, and why.

Open means what the property page means: an HPD litigation pending, a vacate order not rescinded (FDNY: not dismissed or rescinded), arrears in DOF's latest extract, a federal lien neither released nor lapsed and matched to an owner by name and address. Open violations are counted by the distress score's own rule, never as raw rows. Exemption removals are withheld while their reading is checked, as on the property page.

Development potential zoning and floor area from PLUTO; flood and evacuation zones; street widths

126,129 sq ft of on 32 lots · 7 (77,607 sq ft) · 2 (5 lots, 9,385 sq ft)

= the FAR that governs the building (residential, commercial or community facility, the property page's rule) × lot area − built floor area. None is given for an over-built lot, a mixed-use, special-purpose or split-zoned lot, or public land (parks, airports, utilities, transport, government sites, land owned by the city, state or federal government). Rough: no bonus, inclusionary or transfer rule, no overlay or district-boundary adjustment, no zoning-lot merger. A soft site is built to under 50% of that maximum. An assemblage candidate is a group of lots sharing tax-map edges where each neighbouring pair is under-built or held by one owner group.
