853 Carroll Street

The building's age is not settled in the records. PLUTO carries 1920, which for older Brooklyn row houses is often an estimate. Listing records describe it as an 1888 Romanesque Revival house built by the developer Harvey Murdock, and the Landmarks Preservation Commission's historic-district photo records, as indexed, give the same date and builder. Sales materials also credit the design to C.P.H. Gilbert; the commission's index record names a different architect, so we do not repeat the Gilbert attribution. Confirm the architect against the 1973 Park Slope Historic District designation report before relying on it.

Department of Buildings filings describe a five-story, 50-foot residential building with five dwelling units both before and after the work. The renovation (job 321925440) was filed in 2019, permitted in June 2022, and signed off in May 2024 at an estimated cost of $195,000. It covered kitchens, baths and minor interior work; it did not add units or floor area. A condominium subdivision into lots 1301–1305 was filed in March 2024, and the declaration was recorded in April 2024.

PLUTO gives about 5,240 square feet of building area on a 21-by-100-foot lot. Listing records describe the parlor unit at roughly 2,650 square feet and list a garden, and a penthouse on the top floor. Unit sizes were not confirmed against the offering plan's Schedule A.

Because the building is in a historic district, facade, window and rooftop work requires Landmarks Preservation Commission approval.

Per the offering plan filed with the New York State Attorney General (plan CD230177), the plan was submitted July 10, 2023 and accepted January 17, 2024 at a total offering price of $9,280,000, with 853 Carroll Street LLC as sponsor, for five residential units. The Attorney General's database shows no effective date and no units sold. The recorded deeds show the sponsor closing on every unit, so the database is out of date. Amendments were not reviewed; the Attorney General's online record returned no data when we checked in October 2026.

Sponsor deeds recorded in ACRIS:

• Unit 3: $1,614,600, deed dated May 30, 2024
• Unit 2: $1,700,000, deed dated June 14, 2024
• Unit 4: $1,400,000, deed dated November 7, 2024
• Unit 1: $3,039,237.50, deed dated July 10, 2025
• Unit G: $721,175, deed dated July 10, 2025, to the same buyer as unit 1

Units 1 and G were deeded the same day to the same buyer for a combined $3,760,412.50; listing records had also marketed the two as a combination. Listing records had shown the parlor unit at $3,999,000 and later $3,650,000 before the close.

The first resale followed in February 2026: unit 4 sold for $1,675,000, 19.6 percent above its $1,400,000 sponsor price fifteen months earlier. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $1,811/sf (recorded) across 1 sale. Median listing discount 3.5% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01068-7504; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

It is a resale building now. The sponsor has no unsold inventory left, so there is no offering plan pricing to negotiate against. Price against the five sponsor deeds and the unit 4 resale.

Five owners carry everything. Any roof, facade or boiler cost is split five ways, and one owner of units 1 and G holds two of the five lots. Ask for the budget, the reserve balance and how common charges are allocated between those two lots.

Landmark work. Exterior work goes through the Landmarks Preservation Commission, which adds time and cost.

Closing costs. On a resale the buyer pays the state mansion tax of 1% at $1 million and above; the seller customarily pays the transfer taxes. Use the calculators below.

Taxes. No exemption appears in the records reviewed. Confirm the current assessment on each unit lot.

Recorded comparables are recent and specific. All six recorded sales here date from 2024 or later: five sponsor deeds and one resale that gained 19.6 percent in fifteen months. A buyer's broker will use all of them.
