Mercer Street between Spring and Broome is one of the few blocks in SoHo where the nineteenth-century commercial street survives more or less whole: Belgian block underfoot, loading platforms and areaways at the sidewalk, cast-iron fronts rising five and six stories on both sides with almost no infill from the twentieth century. 77 Mercer is a working part of that wall rather than a standout on it, and that is the accurate way to describe the building. It was built in 1875–76 to the designs of Jesse W. Powers for John Ruszits as a commercial store building, one of the many mercantile structures thrown up in the district during its dry-goods decades, and it was still a commercial property when the Landmarks Preservation Commission drew the SoHo–Cast Iron Historic District around it in August 1973.
The thing that makes the building legible today is its width. Most SoHo lots are twenty-five feet. This one is fifty — a double lot with a hundred-foot depth — and the facade is composed as two bays with separate entrances, which is why the address confusion exists in the first place. The Department of Finance chose the low house number for its records and calls the lot 73 Mercer Street; LPC designated it as 73–77 Mercer Street; the condominium, the DOB filings and every recorded deed use 77 Mercer Street. A buyer pulling city data on this building will find the tax bill, the assessment, and the PLUTO record filed under an address that does not appear on the front door. It is the same building.
What the fifty-foot width buys residentially is the plan. Ten apartments across five upper floors means two per floor, each occupying half of a 50-by-100 footprint — the classic SoHo half-floor loft, with the north units facing one exposure and the south units the other, ceiling heights carried over from mercantile construction, and column-and-beam structure that tolerates open plans. Below them, two ground-floor commercial units and the retail frontage account for roughly a third of the building's gross area, which matters to the condominium's budget: a meaningful share of common expense is carried by commercial space rather than by the ten residences alone.
The tax posture is worth stating plainly because it runs against what buyers expect from converted product. There is no abatement here and there never was one in the current records — no 421-a, no J-51 phasing out, no ICAP. The residences are taxed at full assessment and have been. Buyers underwriting against abated new-development inventory elsewhere downtown will find the monthly number at 77 Mercer higher relative to price than the comparison implies, and it does not step up later because it never stepped down.
Architecture and unit composition
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.
Building operations and capital posture
Public records document a building that has attended to its envelope rather than deferred it. DOB filings show sidewalk sheds and facade repair in 2000 and again in 2006, a new cornice installed in 2008, and reconstruction of the sidewalk vault — waterproofing membrane, steps, diamond plate — 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.
What public records do not show is 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.
Policy framework
Landmark review is the operative constraint. Anything visible from the street — storefront, windows, ironwork, cornice, rooftop mechanical equipment with a sightline to Mercer Street — needs an LPC permit before the Department of Buildings will issue one. Work that changes what is visible requires a Certificate of Appropriateness; work that does not can often proceed under a Certificate of No Effect or a minor-work permit. LPC's permit database shows an active filing history for lots across this block. Budget the review time into any renovation schedule.
The remaining policy stack is not published. 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, none of which appear in public records for this building. The condominium structure ordinarily permits subletting, non-primary occupancy and entity purchase subject to a right of first refusal — but that is the form's default, not a documented fact about this building. Confirm each with the managing agent.

77 Mercer trades as SoHo half-floor loft product: whole-side apartments in a landmarked cast-iron building on a cobblestone block, priced on square footage, ceiling height, exposure and the quality of the last renovation rather than on services, which the building does not sell. Recent activity has centered in the mid-$3 million range. That places it below the district's marquee full-service loft condominiums and above the walk-up co-op tier — the pricing of a boutique, low-density, landmarked building with real floor plates and a modest service program. Condition is the largest single variable in this building type; a renovated half-floor and an original one on the same line are not the same product. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
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 taxes at full assessment. There is no abatement to model, no burn-off date, and no step-up. 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.
What to know if you’re selling
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.

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.
