77 Mercer Street

The facade is cast iron, per LPC's designation record, on a fifty-foot frontage divided into two bays with separate entrances — a composition that reads as a pair of adjoining store buildings and was likely built to be leased that way. LPC's record does not assign the building a primary style, which is itself informative: it is a competent commercial front of its decade rather than a signature work, and its value in the district is contextual.

Above the ground floor, the building is a five-level residential stack of half-floor lofts, two to a floor, running 2N and 2S through 6N and 6S in the recorded unit schedule. Loft proportions govern: deep floor plates, high ceilings, large window openings on the Mercer Street elevation, and structural columns that dictate where walls can and cannot go. Interior alteration filings on record include the installation of new glass partitions and a spiral stair within one apartment, which is the ordinary vocabulary of loft renovation here. The eleven storage units in the condominium's unit schedule are separately deeded — a buyer should establish at contract whether a storage unit conveys with the apartment or has to be bought.

Public records show envelope work filed over the years. DOB filings show sidewalk sheds and facade repair in 2000 and again in 2006, a new cornice filed in 2008, and reconstruction of the sidewalk vault — waterproofing membrane, steps, diamond plate — filed in 2009. Interior retail fit-outs at the base were filed in 2013 and 2014. There is no record of an open Alteration Type 1 or of a building running on temporary certificates of occupancy; completion of the filed work and current condition need confirming from recent engineering reports and board materials.

The reviewed records do not establish the condominium's operating budget, reserve position, common-charge history, or whether any assessment is live. Nothing about staffing, amenities, or a service program is documented either. For a building of this size those questions are answered only by the offering plan, the current budget and the most recent financial statement, and they should be requested from the managing agent before an offer is made.

Landmark review is the operative constraint. Exterior alterations — including storefront, windows, ironwork, cornice and rooftop mechanical equipment — generally need LPC approval before the relevant DOB permit. Eligible visible work may be approved by staff, and some maintenance is exempt; confirm whether the proposed scope requires a Certificate of Appropriateness, Certificate of No Effect or Permit for Minor Work. LPC's permit database shows an active filing history for lots across this block. Budget the review time into any renovation schedule.

Confirm the remaining policy terms. Pet rules, sublet terms, pied-à-terre treatment, LLC and trust purchases, minimum down payment, and any resale capital contribution are governed by the offering plan, the by-laws and the house rules, which were not established by the reviewed material. Condominium tenure alone does not establish subletting, non-primary occupancy or entity-purchase permissions. Confirm each with the managing agent.

Recent sales

Recent closings 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 (2024) cleared a median $1,918/sf (recorded) across 2 sales. Median listing discount 3.0% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00485-7501; each condominium apartment is its own tax lot). 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 from recorded condo declarations and offering plans.

Reconcile the address before you order anything. Title, tax bills, assessment records and PLUTO may return 73 Mercer Street. That is this building. Give your attorney the BBL — 1-00485-7501 — rather than the street address.

Underwrite the actual tax bill. The roll shows no exemption to model, no burn-off date, and no step-up; check the current bill for any abatement. Run the True Monthly Carrying Cost Calculator against the actual current tax bill.

Ask for the commercial picture. Roughly a third of the building's gross area is retail, held in two ground-floor commercial units. How that space is owned, what it contributes to common expense, and whether it is vacant are questions the offering plan and the current budget answer and the public record does not.

Landmark status is a renovation cost and a schedule. Windows, storefront and any street-visible rooftop equipment go through LPC. Price the approvals and the delay, not just the work.

Lead with the plate and the block. A fifty-foot-wide half-floor loft on a Belgian-block stretch of Mercer inside the Cast Iron District is a specific product with a specific buyer. Photograph the width and the light; that is what is being bought.

Have the documents ready. In a ten-unit building with no published policy stack, the buyers who move fastest are the ones whose attorneys get the offering plan, by-laws, house rules, budget and most recent financial statement without a delay. Assemble them before listing.

Be direct about services. Buyers cross-shopping full-service loft condominiums will ask. A clear answer early is worth more than a vague one late.
