A Private Pricing Opinion — what your apartment at 90 Eighth Avenue 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.
Most of Park Slope's housing is brownstones and six-story walk-ups. Its prewar elevator buildings are concentrated in a few blocks near Grand Army Plaza, and 90 Eighth Avenue is one of them: an eleven-story Sugarman & Berger apartment house from 1927, one block from the park. It combines two things that are hard to find together here — a full-height prewar building with a doorman, and a location inside the historic district, with the landmark protection that comes with it.
The architect matters for comparison. Sugarman & Berger were among the busiest apartment-house designers in New York in the 1920s, and the same year they designed 1 Plaza Street West, the sixteen-story neo-Gothic cooperative on the Plaza. Both buildings have the firm's usual planning: apartments off a central elevator core, a limestone base with brick above, and terra-cotta trim. 90 Eighth Avenue is the smaller and quieter of the two, on a residential side street.
The ownership history is typical of Brooklyn's 1980s conversion wave. The rental building changed hands several times in the late 1970s, and in September 1981 the sponsor, 90 Eighth Avenue Associates, conveyed it to the tenant corporation. The "Housing Co." in the corporation's name tends to confuse buyers' attorneys. It is not an HDFC and not a limited-equity co-op. Shares have sold to unrelated buyers in the open market throughout the ACRIS record.
Then there is bulk. The building has about 73,400 square feet on an 11,286-square-foot lot, more than twice what a simple lot-area comparison with current residential zoning gives; that comparison does not establish legal zoning floor area or permitted future work. The historic district also puts exterior change under Landmarks review.
Architecture and unit composition
The building sits on a long, narrow lot — 66 feet on Eighth Avenue and 171 feet down President Street. Most apartments therefore face the side street, and the avenue frontage is held by the corner lines. The limestone base and buff-brick shaft follow the Sugarman & Berger pattern, and LPC records note terra-cotta trim. Records from the city's façade-inspection cycles show repair filings in 2010, 2012, 2015 and 2021, a suspended scaffold for façade work in 2024 and a sidewalk shed in 2025; completion and current condition need confirming.
The apartment lines run from A to G on the lower floors, and the unit mix is wide. Listing records describe classic-seven layouts over 2,000 square feet with long galleries, three- and four-bedroom apartments, and beamed ceilings over nine feet. The building also has one-bedrooms and small ground-floor units — ACRIS records a unit designated 1BB. Owners have combined apartments over the years (1E and 1F were combined under a 2015 filing), and a steady flow of renovation filings shows buyers updating kitchens and baths; condition varies by apartment and needs checking.
The ground floor has held professional offices, which the Department of Finance counts as three non-residential units. A May 2026 Department of Buildings filing proposes converting one of those offices into a residential unit, with an amended certificate of occupancy — the same move 9 Prospect Park West has made with its ground-floor medical suites. It is worth asking whether the corporation owns that space and plans to sell it.
Building operations
Taxes and abatements. The Department of Finance's historical J-51 file shows three awards on this lot. The first, starting in 1981 alongside the conversion, was a 12-year abatement on about $45,600 of certified work and was fully used by tax year 1991. The second, starting in 1994, was a 14-year abatement on about $102,400 of work and was last applied in 2004. The third, starting in 2002, was a 14-year abatement on about $32,400 and was last applied in tax year 2014. The exemption roll for 2021/22 through 2027/28 shows no J-51 or other building-level benefit, only personal exemptions held by individual shareholders. There is no scheduled burn-off to plan for: the tax bill already reflects its full, unabated level. The co-op abatement for owner-occupants is separate and depends on each shareholder's primary residence, so confirm it on the current bill.
Underlying mortgage. The corporation took a $750,000 loan in March 2023. In October 2025 it recorded a new mortgage of about $542,000 and a consolidation agreement bringing the underlying debt to $2.5 million, per ACRIS. The recorded documents do not state the rate or maturity. Ask the managing agent for both, along with amortization and any credit line.
Systems. Department of Buildings records show a new dual-fuel burner and a gas service in 2012, a chimney liner in 2011 and a boiler-room wall replacement in 2020. Every permit is filed as landmarked, which is expected.

Facade safety — Local Law 11
The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2025–30. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

What to know if you’re buying
Get the policy stack in writing early. The flip tax, sublet rules, pied-à-terre and trust/LLC policy, and the board's financing ceiling are not established in the reviewed material. Listing records cite 20 percent down, but confirm it with the managing agent before you make an offer.
Confirm Landmarks requirements for the actual scope. Window, through-wall air-conditioning and other exterior alterations generally need LPC approval; qualifying maintenance may be exempt and some work can receive staff approval. Interior work requiring a DOB permit also needs LPC approval, alongside applicable board requirements.
Ask about the 2025 refinancing. A $2.5 million consolidated mortgage is modest for a 57-unit building, but its terms affect maintenance.
Ask about the ground floor. If the corporation is converting a professional suite into an apartment, find out who owns it, how shares will be allocated, and whether sale proceeds will go to reserves.
What to know if you’re selling
Lead with the architect and the district. A Sugarman & Berger building inside the Park Slope Historic District, one block from the park, is a verifiable story that few competing buildings can tell.
Price your line, not the building. Use same-line and same-layout sales. The size range here makes building-wide averages misleading.
Have the board package requirements ready. Buyers should get the application requirements, the financing limit and any transfer fee in the first conversation.

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.
