A Private Pricing Opinion — what your apartment at 333 14th Street 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.
333 14th Street is a seven-residence condominium on a mid-block South Slope street, about 150 feet east of Sixth Avenue. The new-building application dates to October 2014, and the permit issued in January 2017. City land-use records already carry a 2017 year built. The condominium offering came much later: the sponsor submitted the plan to the Attorney General in March 2023, and it was accepted in November 2024.
The building has an automated parking garage. City records attribute about 7,025 of its 27,440 square feet to garage space, and listing records market individual spaces separately. Off-street parking that can be bought with the apartment is uncommon on a South Slope side street.
The offering is priced well above the neighborhood's small-building average. The current total of $30.4 million works out to about $4.34 million per residence, against a sponsor-marketed range of $2.49 million to $3.495 million. Those two figures do not reconcile, and a buyer should ask why before relying on either.
Architecture and residences
The Department of Buildings filing describes a four-story, 40-foot residential building with seven dwelling units and 22,939 square feet of construction floor area in an R6B district. The filing lists American Development Group LLC as owner and Adam Kushner, RA, as architect of record. The lot is irregular, with 25.8 feet of frontage in city land-use data and 50 feet of frontage on the builders' pavement plan; the building sits about 148 feet from Sixth Avenue.
Unit counts differ by source. The offering plan record shows seven residential units and eight units in all; the new-building filing shows seven dwelling units; PLUTO shows 10. One listing portal gives the building six stories against the filing's four. The plan's Schedule A is the reference for what is being sold.
Listing records describe Residence 2F as a three-bedroom of about 1,463 square feet. Parking is in an automated garage marketed under the name The Vault.
Offering and pricing
Per the offering plan filed with the New York State Attorney General (plan CD230086), the plan was submitted March 29, 2023 and accepted November 12, 2024, with 333 Park Slope Condos LLC as sponsor. The record lists eight units, seven of them residential. The initial total offering price was $17,905,000; the current total is $30,385,000, an increase of $12,480,000, or 70%. The record shows no effective date and no units sold as of October 2026. The amendment-by-amendment detail behind the increase was not available in this review.
The sponsor has marketed the seven residences from $2,490,000 to $3,495,000. Even with every residence at the top of that range, the total would be about $24.5 million. Parking spaces, listed at $200,000 and $225,000, do not close the gap to $30.4 million. Read the amendments for the current price schedule.
| Residence | Layout | Size | Ask | $/sf | Note |
|---|---|---|---|---|---|
| 2F | 3 bed | 1,463 sf | $2,490,000 | $1,702 | Listed November 18, 2024 |
| 2F | 3 bed | 1,463 sf | $1,995,000 | $1,364 | Shown on other listing records; date not confirmed |
| Parking 1 | Automated space | — | $200,000 | — | In contract per one listing record |
| Parking 2 | Automated space | — | $225,000 | — | Listing record |
These are asking prices, not contract prices. Listing records give Residence 2F common charges of $829 a month and real estate taxes of about $1,203 a month, about $2,032 a month combined.

What to know if you’re buying
The plan is not effective. The sponsor cannot close until it declares the plan effective by amendment, which requires a minimum share of units under contract. Until then, a contract binds the buyer to the plan's terms, but closing dates are open.
Price schedule. The 70% increase in the total offering price and the mismatch with the marketed range both point to the amendments. Ask sponsor counsel for the current Schedule A before negotiating.
Certificate of occupancy. The Department of Buildings shows the new-building job with its permit in place and no sign-off recorded in the city's older filing system as of October 2026. Ask whether a temporary or final certificate of occupancy has issued.
Closing costs. In sponsor sales the buyer customarily pays the New York State transfer tax (0.4%, or 0.65% at $3 million and above) and the New York City real property transfer tax (1.425% above $500,000), plus the mansion tax, which is 1.25% between $2 million and $3 million and 1.5% between $3 million and $5 million. Use the calculators below.
Parking. Spaces are sold separately. Confirm whether each is its own condominium unit or a limited common element, and what it adds to common charges and taxes.

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.
