A Private Pricing Opinion — what your apartment at 601 Baltic would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
601 Baltic is a ten-story condominium on Baltic Street between Third and Fourth Avenues, built by a developer that also designed it. It has 21 homes and one commercial unit. Sponsor marketing places it in Boerum Hill; the Attorney General's geocoder places it in Gowanus; both are accurate for a site on the seam.
It shares a tax block with 610 Warren Street, a 2017 condominium with a live 421-a exemption. The two are separate condominiums in every legal respect, with separate declarations and no shared instrument of record. 601 Baltic carries no abatement, so its tax line does not step up later.
The building suits buyers who want a recently completed condominium of about two dozen homes near the Fourth Avenue subway lines, with outdoor space on the roof and, in select homes, private cabanas.
Architecture and residences
Per published construction reporting, the exterior is brick with oversized casement windows and metal fin accents, with the entrance at the southwest corner under a glass and metal canopy. DOB's construction record spans a 2018 new-building application through completion in 2021 on PLUTO, with a temporary certificate of occupancy disclosed to buyers in August 2024. Our profile of the adjacent block records the final certificate of occupancy as issued April 2, 2025.
Sponsor materials describe fluted-wood, satin-gray kitchen cabinetry with quartzite counters, Miele and Fisher & Paykel appliances, honed marble baths, wide-plank floors, in-unit washer and dryer, individually controlled air conditioning and private storage included in the purchase price. Resales offered have been mostly one- and two-bedroom residences of about 700 to 750 square feet; the larger homes are two- and three-bedroom residences and penthouses. Published sources conflict on the unit count (21, 22 and 25 appear) and on the story count (9 and 10); the plan and DOB carry 21 residences, one commercial unit and ten stories.
Offering and pricing
Per the offering plan filed with the New York State Attorney General, the plan was submitted May 19, 2023 at $31.83 million and accepted October 12, 2023 at $32.42 million for 21 residential units and one commercial unit, an average of about $1.47 million per unit.
Amendment 1 (accepted May 3, 2024) declared the plan effective with five units, or 24 percent, in contract, updated taxes, changed the sponsor control period and added a mortgage recording tax credit. Amendment 2 (accepted September 17, 2024) disclosed the temporary certificate of occupancy and a $5,000 escrow for the permanent certificate. Amendment 3 (accepted February 4, 2025) updated sponsor financial disclosures and sponsor-controlled board information. The record shows five units sold; it has not been updated.
Published records show one-bedroom closings around $1.0 million and two-bedroom closings around $1.1 million to $1.16 million between July 2024 and January 2026, roughly $1,400 to $1,560 per square foot. Those figures are not verified against recorded deeds and are not a price list. Current asking prices had not been published as of October 2026.

What to know if you’re buying
Deposit and contract. Sponsor contracts typically take a 10 percent deposit, usually split in two payments. The plan sets this building's terms.
Closing costs. In sponsor sales the buyer customarily pays New York City and New York State transfer taxes. The New York State mansion tax applies to purchases of $1 million or more and rises in steps on higher prices. Reported one- and two-bedroom prices of about $1 million put the threshold in play.
Certificate of occupancy. The plan disclosed a temporary certificate in August 2024. A buyer today should confirm that the permanent certificate is in place and that the escrow is released.
Common charges and taxes. Published common charges run from about $820 to $880 a month on one- and two-bedrooms. Read the plan's budget and the amended tax figures. With no abatement, the current tax line is the long-run line.
Board control. Amendments 1 and 3 changed and updated sponsor-control terms. Ask when owners elect a majority of the board.
What to know if you’re selling
The plan record shows five units sold and has not been updated, so a resale may compete with sponsor inventory on the same line. Confirm what the sponsor still holds. Reference recorded closings, not listing prices, and cite the absence of a tax step-up, which separates the building from its abatement-bearing neighbor.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
