150 North 5th Street (The Rialto)

The structure is a 1910 industrial building of roughly 36,600 square feet, reskinned rather than restored. The street elevation is flat and modern, with thin projecting window frames, a rounded and windowed bay, and stepped terraces above — a contemporary façade on an early-twentieth-century frame. The alteration filings show new structural steel installed through the building, new mechanical ductwork, fans and chillers, and a full new plumbing riser system, so the conversion was a deep intervention rather than a partition job.

Residences run across four floors in a lettering scheme that skips letters on every floor, the ordinary signature of a plan revised during construction. Units range from roughly 810 to 1,840 square feet on the current roll. The largest are duplexes, and the plans carry coffered ceilings and large low-E windows, with fireplaces in some residences. Because the lot is deep and mid-block, exposure and floor position matter more here than they do in a shallow street-facing building, and two residences of identical square footage on the same floor can be very different apartments.

Vertical circulation is a single elevator serving thirty-one residences on four floors — appropriate to the scale and worth confirming as to age and service history, since the equipment dates to the 2006–09 conversion.

The Rialto runs as a boutique building. The amenity set — virtual doorman, package room, elevator, common garden, shared roof deck — defines the listed services, but does not establish their cost or management quality. There is no commercial tenant to subsidize the budget and no garage to maintain; confirm expenses and any other income in the current budget rather than inferring low overhead.

Capital activity in the record is light and recent. A lobby and corridor renovation was filed in 2021 covering new finishes, fixtures and millwork, with no exterior scope. Nothing in the current Department of Buildings file indicates an open façade job or a sidewalk shed. The absence of an open filing does not establish façade condition. At the documented four-story height, periodic FISP filing is not triggered by height alone; the program applies to buildings higher than six stories. Request current façade maintenance records, the budget, reserves, assessments and elevator service history.

One structural item belongs on every diligence list here. ACRIS shows a small group of units held under common single-purpose limited-liability-company ownership since the mid-2010s, financed together and refinanced together in 2020 and again in 2022. A block of investor-held units inside a thirty-one-unit condominium affects the owner-occupancy ratio, and the owner-occupancy ratio affects conforming and jumbo financing. Ask the managing agent for the current figure before you go to a lender, not after.

Ownership form: Condominium. Sales and leases are governed by the declaration and by-laws and, as is standard, a board right of first refusal rather than a cooperative approval.

Pets, subletting, pied-à-terre, LLC and trust purchasers, flip tax, financing minimums: Not documented in the materials on file. Read the current declaration, by-laws and house rules, and confirm anything policy-related with the managing agent before you rely on it.

Real estate taxes: No building-wide exemption or abatement on the FY2027 roll. The 421-a fifteen-year benefit ran from 2011 and has expired (final benefit year FY2025, 2024/25, on the Department of Finance exemption roll; confirm on the unit's bills). Underwrite the current full assessment on the specific unit, and check any tax figure quoted from before the FY2026 roll against the current bill.

Ground floor: The condominium contains no commercial unit. Every one of the thirty-one lots is a residence.

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 (2026 to date) cleared a median $1,536/sf (floor-adjusted) across 1 sale. 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 1.8% 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 3-02344-7502; 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.

Re-underwrite the taxes from scratch. The 421-a exemption has expired. Pull the current tax bill for the specific unit and compare it with the tax component of any carrying-cost number computed from an older bill; take common charges and assessments separately.

Ask for the owner-occupancy ratio in writing. A block of LLC-held units in a thirty-one-unit condominium is a financing question before it is anything else. Your lender will ask; ask first.

Read the declaration for policy. The policy terms have not been verified from the offering plan. Pets, sublets, pied-à-terre use and any resale contribution have to be confirmed from the governing documents and the managing agent.

Price the duplexes separately. Multi-level residences on a deep four-story plate are a different product from a simplex of the same footprint and should not be compared to one.

Ask about the elevator and the roof. One cab, thirty-one units, equipment dating to the conversion. Get the service history and the reserve position.

Lead with the fact that the cliff is behind you. This building’s recorded 421-a benefit has ended; compare the actual schedules of competing buildings rather than assuming most still have a step-down ahead. Say so, with the roll year, and let buyers check it.

Tell the conversion story properly. The family that manufactured furniture on this site since 1939, on land they had owned since 1983, converted their own plant when the 2005 rezoning made it possible, and named the building for the company. It is a better and truer story than "loft conversion."

Photograph the volume. Coffered ceilings, wide glazing and multi-level plans do not read on a floor plan. Wide shots, and a plan that shows how deep the apartment runs.

Document the renovation. Permits, invoices and dates. In a nearly twenty-year-old conversion, buyers assume the worst about the mechanicals unless shown otherwise.

If you're considering The Rialto, also evaluate:

• The Mill Building (85 North 3rd Street) — a non-eviction conversion of a 1910 industrial loft building a few blocks south; the closest peer by vintage and product
• 55 Berry Street (Berry Street Lofts) — the Northside conversion carried out by BSA variance two years before the rezoning; the same building type on a different regulatory path
• 161 Grand Street (The Solita) — a boutique conversion alternative in Manhattan, rather than Williamsburg
• Warehouse 11 (214 North 11th Street) — Northside new construction answering a loft brief
• 125 North 10th Street — the 85-residence 2007 Northside condominium; the amenity-first post-rezoning alternative
• 49 North 8th Street (North8) — post-rezoning new construction with an enclosed garage, two blocks north
• The Esquire Building (330 Wythe Avenue) — the 75-residence Southside industrial conversion; the larger loft alternative
• The Gretsch (60 Broadway) — the 1916 instrument factory converted in 2003; the marquee Brooklyn loft conversion
• Austin Nichols House (184 Kent Avenue) — the 1915 warehouse converted in 2016; loft conversion at scale, on a much later basis
