A Private Pricing Opinion — what your apartment at 308 N7, the marketing name; press coverage during construction used N7 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.
308 North 7th Street is the last generation of Williamsburg condominium to carry the old 421-a program. The DOB application was filed in December 2014 and foundation work in October 2015, ahead of the end-of-2015 cutoff for starting construction under the old program. The building did not deliver until 2019. The result is a 2019 building with a tax benefit designed for a 2015 start, and eight years of it are still to run.
For a buyer, that benefit is the central number, and it is not the same for every apartment. The exemption is capped per unit, so the smaller residences are almost fully exempt on their added value today while the larger ones already pay tax on assessed value above the cap. Two apartments on the same floor can carry very different bills.
The sponsor, N7 Owner LLC, sold the building to separate buyers between April 2019 and June 2021, per ACRIS. It holds nothing today. The Department of Finance classifies one penthouse as a condominium rental unit (class RR), meaning it is recorded as rented out. That is one unit of 45, and the building is not a rental wrapper.
Architecture and unit composition
Isaac & Stern designed a masonry building in two registers: a ground floor in dark herringbone brick, and a pale, distressed brick above, cut with oversized metal-framed windows, per press coverage. The massing steps back in terraces, which is what gives so many apartments private outdoor space.
The 45 residences run from one to three bedrooms, per published marketing materials. The three garden-level homes (A, E and F) sit at the base with private garden space. Floors two through seven hold between five and eight apartments each, thinning as the building steps back, and the three penthouses sit at the top. Kitchens carry custom oak cabinetry, Arabescato Corchia marble counters and Bosch appliances, per published marketing materials.
Parking and cabanas are not condominium units. Marketing described an indoor garage of 23 spaces and cabanas for purchase, but ACRIS and the Department of Finance show only the 45 residences. The spaces and cabanas are therefore held some other way: by license, lease, or as limited common elements assigned to particular apartments. Ask how a given space or cabana is held, whether it transfers with the apartment, and what it costs each month.
The block has changed since the building opened. A separate seven-story rental building was completed next door at 304 North 7th Street in 2024, per city records. It is a different tax lot and not part of the condominium, but it affects light and outlook on the west side of the building.
Building operations
A 45-residence building with an attended lobby, a top-floor amenity floor and a garage runs a fuller budget than a walk-in boutique building. We have no financial statements on file. Ask for the current budget, the reserve balance and any assessment history, and ask how garage and cabana income, if any, flows into the budget.
At nine stories, the building is subject to Local Law 11, the city's façade inspection program for buildings over six stories. Ask for the most recent filing, or the date the first one is due, and its classification. On a stepped building, terrace waterproofing and roof membranes over occupied space are the maintenance items to watch.
The tax position
Department of Finance records show a 15-year 421-a exemption with a cap on every residence (code 5118, "421A 15 YR CAP"). 421-a is the state program that exempted the added value of new construction from property tax for a fixed term. This is the pre-2016 program, not 421-a(16), the Affordable New York program that replaced it. The benefit began in 2019/20. It runs at full value, up to the cap, for eleven years through 2029/30, then steps down to 80, 60, 40 and 20 percent over the following four years. From 2034/35 the building is fully taxed.
The cap is what buyers miss. The exemption covers each unit's added value only up to a fixed ceiling of assessed value. The ceiling began at $65,000 per unit and has risen about 3 percent a year; on the 2026/27 roll it is $110,658. Nineteen of the 45 residences fall under it and pay tax only on a small base value. The other 26 exceed it and pay tax on everything above the cap, so their bills are already much higher than the smaller units' and will rise further when the step-down begins.
Pull the tax record for the specific unit. A tax figure from a neighbor's listing, or from a smaller apartment, will not apply.
Recent sales
308 North 7th Street trades as late-cycle Williamsburg new construction, priced in dollars per square foot, with premiums for private outdoor space, the garden homes and the penthouses. Resale pricing here has to account for the tax schedule. A buyer is paying for eight more years of benefit on a small unit, and for a partial benefit on a large one, and those are different values. Index market statements to 2025, the last complete year. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
Model the tax bill through 2034. Take the current bill, then add the step-downs from 2030/31. On a capped unit, the increase starts from a higher base.
Find out how parking and cabanas are held. Neither is a deeded unit. Get the license or assignment in writing before you price it in.
Get the offering plan and the declaration. We have not reviewed either. They set the leasing, pet and alteration rules and the working-capital contribution.
Check the terrace. Private outdoor space is the building's selling point. Confirm what is exclusive to the unit, who maintains the membrane, and whether there is any open leak history.
What to know if you’re selling
Show the tax schedule with the listing. Buyers will find the cap. Present the current bill and the step-down together, and explain why a large unit's bill is higher than a small neighbor's.
Sell the outdoor space. Twenty-nine of 45 residences have it; if yours does, photograph and measure it.
Document parking or cabana rights. If a space or cabana goes with the apartment, have the paperwork ready. It is not in the deed.

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.
