345 Clinton Avenue (Clinton Hill Co-ops, South Campus)

The South Campus occupies Block 1944 between Clinton, Waverly, Lafayette and Greene Avenues, with a fifth building at 325 Clinton Avenue on the block to the north, over the Lafayette Avenue subway entrance. The Department of Finance records 424 apartments on the tax lot addressed 345 Clinton Avenue; the offering plan's site plan shows the South Campus buildings running 96 to 112 apartments each across 12 to 14 stories.

Floor-to-floor heights run approximately 8 feet 10 inches. Each floor is served by two elevators and a scissor-stair pair off a central corridor, with the compactor chute in a small ventilated room between the elevators. Apartments were delivered with wood parquet floors, plaster walls and ceilings, wood pantry, wall and base cabinets, gas ranges and tiled bathrooms; first-floor lobbies and corridors are terrazzo with stenciled plaster. The share schedule for the South Campus buildings concentrates in 2½-, 3½- and 4½-room apartments, with larger lines dispersed through the upper floors.

Because the plans repeat across twelve buildings, the differentiators inside the inventory are floor, exposure — courtyard and Waverly Avenue versus Clinton Avenue — line, and renovation state. There is no in-unit laundry anywhere in the complex; washing machines and dryers are prohibited in apartments and the laundry rooms are the substitute.

345 Clinton Avenue is the plant building for its section. The offering-plan engineer's report described four Kewanee boilers built in 1946 and converted from coal to oil in the cellar, supplying South Campus steam heat and domestic hot-water heating through underground mains. It described domestic water pumped to a 20,000-gallon Rosenwach wood tank above each building's elevator machine room and heating controls zoned by outdoor-air and condensate sensors. Those historical specifications do not establish which equipment remains in service. Confirm the current plant, replacements, operating condition, noise and service access, together with the capital plan.

The capital history is documented in the plan. A GMAC first mortgage closing March 31, 1997 carried a $4,336,600 repair escrow for asbestos abatement, paving, repointing and masonry, boiler repairs, roof work, elevator renovation and replacement, Local Law 10 work and electrical wiring and metering, together with a monthly replacement-reserve deposit; the audited statements for the year ending March 31, 1999 record that mortgage maturing April 1, 2027. Any 2026 buyer should ask management directly for the corporation's current debt position, maturity and refinancing plan.

Maintenance ran at approximately $8.417 per share per month as of February 1, 2020 per the plan's twenty-fourth amendment. The board seats seventeen directors, and the amendment states expressly that neither the sponsor, the co-sponsors nor other holders of unsold shares have ever controlled it. As of February 1, 2020 the sponsor group held 144 apartments, a co-sponsor group held 61, and the corporation itself owned 16; those units are rented, and the current figures should be requested at contract because lenders weigh them. Management history and current agent details are maintained in The Roebling Research Library and confirmed with clients during diligence.

Purchaser review: Full cooperative board approval, with application and interview.

Subletting: Board resolution, or written consent or vote of holders of at least 66⅔ percent of outstanding shares, with conditions the board may impose; only resident shareholder-directors vote on sublet consent.

Pets: Permitted with the board's express written permission, revocable. Dogs must be carried or leashed in common areas and on the grounds; walking on the lawns and relief anywhere on cooperative property are prohibited.

Smoking: Permitted only inside apartments purchased before June 9, 2014; every apartment sold after that date is smoke-free. Smoking is prohibited in all indoor common areas, in courtyards, on terraces and roofs, in parking areas, and within 25 feet of building doors.

Washer/dryer: Prohibited in apartments.

Insurance: Shareholders must carry comprehensive liability and property damage coverage of at least $500,000, with the board able to require up to $1,000,000.

Alterations and exterior work: Structural, plumbing and electrical alterations require board consent; because the building sits inside the Clinton Hill Historic District, exterior and window work also requires LPC approval.

Flip tax / transfer fee: None enacted as of the 2000 restated plan; the board retains the right to impose one on net profit up to 10 percent of gross selling price without a two-thirds vote. Confirm current policy, move fees and assessments in writing.

Recent sales

Recent transfers at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $902/sf (floor-adjusted) across 3 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 0.0% from the last ask.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01944-0004). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.

You are inside the historic district here. Designated November 10, 1981, the Clinton Hill Historic District takes in the South Campus. Window replacement and any exterior alteration go through Landmarks, and that is a scheduling and budget fact worth knowing before you plan work.

This building carries the South Campus plant. The historical engineer's report located four 1946 boilers and the section's heating controls in the cellar. Confirm the equipment now in service, its condition, replacements and the capital plan.

The rulebook is restrictive by design. Two-thirds shareholder consent for sublets absent a board resolution, no washers or dryers, and a smoke-free apartment if you buy today.

Ask about the mortgage. The 1997 first mortgage was recorded as maturing April 1, 2027. Get the corporation's current debt and refinancing plan, then run True Monthly Carrying Cost analysis against the apartment's maintenance and any assessment.

The G train is around the corner. Clinton–Washington Avenues on Lafayette Avenue is a block away, with the C at Lafayette Avenue and Fulton Street a short walk south.

Lead with the district. A landmarked apartment on the Clinton Avenue mansion row is a sentence most large Brooklyn co-op listings cannot write. Pair it with the Harrison, Fouilhoux & Abramovitz attribution.

Show the plan, not just the rooms. The stepped elevation that puts nearly every apartment on a corner with cross ventilation is a design argument a buyer can verify standing in the apartment.

Stage the courtyard side. The eight-to-nine-foot grade drop from Clinton Avenue into the landscaped court is the South Campus's best feature and the hardest one to convey in a floor plan.

Price per room against the complex and its peers. The right comparables are the other Clinton Hill Co-ops buildings and the large Clinton Hill and Fort Greene cooperatives, adjusted for the historic district position.

Disclose the plant and the house rules up front. Both come out in diligence; leading with them protects the deal.
