A Private Pricing Opinion — what your apartment at The 99 2nd Place Condominium 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.
420 Court Street is a four-residence condominium on the corner of Court Street and 2nd Place, filed with the Attorney General as The 99 2nd Place Condominium. The lot held a one-story bank branch, per Department of Buildings records. Rather than demolish it, the sponsor withdrew a 2021 demolition application and refiled the project as a new building that keeps elements of the old structure, rising to six stories.
The offering total is $16.49 million across six units, four of them residential. That is about $2.75 million per unit if the total were spread evenly, but the plan's two non-residential units take a share the public record does not break out, so the per-residence figure is likely higher. No asking prices were published as of October 2026.
The sponsor group also built 379 12th Street in Park Slope, which sold its six residences between December 2025 and March 2026, with the same architect. That building is the closest guide to how this one may be priced and finished.
Architecture and residences
Design Studio Associates filed the job in January 2022 as an alteration requiring a new certificate of occupancy: the existing one-story, 20-foot commercial building becomes a six-story, 70-foot mixed-use building with four dwelling units and about 14,734 square feet of construction floor area. The first permit issued in May 2024. The corner lot has about 158 feet of combined street frontage, per a sidewalk filing.
The Department of Buildings completed the allocation of condominium lot numbers in May 2026, and a second allocation filing has been with an examiner since October 2026. No certificate of occupancy appears yet. Unit sizes, layouts and finishes have not been published; Schedule A of the plan states them.
Offering and pricing
Per the offering plan filed with the New York State Attorney General (plan CD250302), the plan was submitted September 12, 2025 and accepted June 23, 2026, with 420 Court Street LLC as sponsor. The record lists six units, four residential. The total offering price is $16,490,000, up $1,844,000, or 12.6%, from the initial $14,646,000. The amendments behind the increase were not available for this review. The plan has not been declared effective, and no units are recorded as sold.
No asking prices or recorded sales were found as of October 2026. For a reference point, the sponsor group's 379 12th Street recorded six sales from $1.93 million to $2.85 million, about $1,290 per square foot for the larger lower duplexes and $1,650 to $1,830 for the upper homes, in a three-story building with a penthouse.

What to know if you’re buying
The plan is not yet effective. A contract signed now becomes binding only when the sponsor declares the plan effective, which requires a minimum share of units in contract. Your deposit stays in escrow until then. Read the effectiveness terms and the sponsor's right to abandon the plan.
The non-residential units. Ask what the two non-residential units are, who uses them, and how common charges and the building's insurance are split between the residential and commercial sides.
Delivery and the certificate of occupancy. Closings follow a temporary or final certificate of occupancy. Ask for the sponsor's target date and the status of the open Department of Buildings filings.
Closing costs. In sponsor sales the buyer customarily pays the New York State transfer tax (0.4%, or 0.65% at $3 million or more) and the New York City real property transfer tax (1.425% above $500,000), plus the state mansion tax: 1.25% from $2 million and 1.5% from $3 million. Use the calculators below.
Carrying costs and abatement. The plan's budget sets common charges and projected taxes. No tax abatement has been confirmed in this review.

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.
