166 Montague Street is a residential conversion of the Franklin Trust Company Building on Montague Street. The building went up in 1891 as the home of the Franklin Trust Company, on the corner where Montague meets Clinton in the middle of what nineteenth-century Brooklyn called its bank row. George L. Morse designed it: ten stories of Romanesque Revival masonry with a carved arched entrance, a hipped red-tile roof carrying dormers, and a bust of Benjamin Franklin over the doors — a building whose entire architectural argument was that the institution behind it was solvent, permanent and civic.

The institution was, for a while. The Franklin Trust Company operated from 1888 until 1920, drawing its board from families whose names are still on the neighborhood's streets — Low, Pierrepont, Woodward, Packard, Hulburt. In 1920 it merged into the State Bank of America; that corporate line ran on through the First National City Bank of New York in 1955 and into Citibank by 1976. The building spent most of the twentieth century as offices above ground-floor retail, the condition it was in when it was designated as part of the Brooklyn Heights Historic District in 1965 and the condition it stayed in for another four decades.

The residential conversion is recent and well documented. Montague Realty LLC filed a condominium offering plan accepted April 28, 2008, with Rothzeid Kaiserman Thomson & Bee as sponsor's architect. The plan offered twenty-four residences against an aggregate offering price of $26,060,000, held back a retail unit in the cellar and basement and an office unit occupying the remaining cellar, the first floor and the mezzanine, and warned purchasers plainly that this was an existing building — that most structural components would not be altered and that floors and walls in an 1891 masonry structure may not be level or flat. The condominium was declared effective on January 4, 2010, the date of the first closing; a final certificate of occupancy issued April 27, 2011.

The history combines a bank-building conversion with condominium ownership. The first is genuine landmark architecture at residential scale — a designated nineteenth-century bank building whose street elevations are protected twice over, by LPC jurisdiction and by a façade conservation easement granted to the National Architecture Trust. The second is condominium ownership, whose specific rights and obligations should be read in the governing documents. Compare its architecture with identified Brooklyn Heights condominiums; leasing is permitted with conditions, and financing, trust and non-resident ownership rules should be confirmed in the current declaration and bylaws.

The countervailing facts belong in the same paragraph. This is a mixed-use condominium — retail below, an office unit at the base — and the plan is explicit that the sponsor makes no representation about noise from either. There was no initial reserve fund, and the first audit noted that no study of future major repairs and replacements had been performed; the plan's own answer to a future capital need was an assessment. The sponsor supported the residential section with a $75,000 annual contribution for the first three years and disclosed in advance that common charges would need to rise roughly 5 percent in 2013 when that support ended. None of this is disqualifying for a 2026 buyer, and all of it belongs in the current financial statements rather than the 2008 paperwork.

Architecture and unit composition

Morse's exterior is the reason to be here. The masonry, arched entrance, tile roof and dormers define this ten-story 1891 commercial building’s street presence. Because the street-facing façades are protected both by the historic district and by the conservation easement, they cannot be altered or replaced beyond ordinary repair and maintenance without approval — a durable constraint on the building and a durable guarantee to the buyer. The building is over six stories, so Local Law 11 cyclical façade inspection applies.

Inside, the unit plan follows the floor. The second floor was cut as loft apartments: 2A at roughly 1,562 square feet as a two-bedroom, two-bath loft; 2B at 983; 2C at 1,044; and 2D at 884 as a studio with a bath and a half and a sleeping loft. Floors three through eight run a conventional mix — one-bedrooms of roughly 699 to 838 square feet and two-bedrooms of roughly 1,218 to 1,242 — with three-bedroom, two-and-a-half-bath configurations of about 1,536 to 1,656 square feet on the upper floors. The top of the building carries the two most distinctive homes: a three-bedroom of about 1,550 square feet and penthouse 9C at roughly 1,863 square feet with a 260-square-foot terrace, offered at $1,986,000 when the plan came out. Residential floor area runs a little over 27,600 square feet against roughly 9,900 square feet of commercial space.

Layout quality varies more than square footage does. A gut conversion inside a nineteenth-century office structure produces irregular window placement, deep floor plates on some lines, and ceiling conditions that differ floor to floor. Read the plans in Part II of the offering plan against the specific unit before any offer.

Building operations

The condominium began operating on January 4, 2010 with United Management Corp., a sponsor affiliate, as managing agent — disclosed as a related-party transaction in the first audited financial statement. Sponsor control of the board was set by the plan to end five years after the first conveyance or on the sale of half the common interests, whichever came first, and the sponsor held three of five seats as late as March 2012. The sell-down took time, as it did for any conversion that hit the market in 2008: at December 31, 2010 the sponsor still owned 42 percent of the residential units together with the office and retail units, and by February 2012 fourteen units remained unsold. That transitional period is the context for the early financial statements and should be read as history; confirm the sponsor's remaining position, if any, in diligence.

The operating budget is small and legible. The 2012 budget projected $360,828 in revenue — $256,697 from residential common charges, $21,457 from the office unit, $7,774 from the retail unit and the sponsor's $75,000 contribution — against $300,500 of operating expenditure, led by utilities at $85,000 and payroll at $82,500. Certain costs sit with residential owners alone: staff wages, electricity, water and sewer, HVAC and gym maintenance, rooftop and landscaping. The Roebling Research Library holds the offering plan and amendments one through eight, the declaration and by-laws, the house rules, and financial statements through 2014–15; current financials, the reserve position and the latest façade cycle are reviewed with clients during diligence.

Policy framework

Ownership form and leasing: Condominium. A unit owner takes fee title, and the sale or rental of a unit is subject to a right of first refusal in favor of the Board of Managers rather than to a cooperative approval process. Gifts, devise and intestate transfer are unrestricted under the plan; mortgage financing is at the owner's discretion, subject to common charges being current. Confirm current by-law provisions and any minimum lease term with management.

Pets: Dogs, cats or other common household pets permitted, not more than two per unit, subject to board rules on size and permitted noise; dogs carried or leashed anywhere in the common elements.

House rules: No change may be made to the façade; ground-floor commercial tenancy carries a carve-out for storefront signage and awnings. No signage, aerials or window displays from residential units. Board consent is required to decorate or furnish any common element.

Working capital and reserves: Each purchaser contributed one month's common charges at closing, and no flip tax or transfer fee is documented in the plan. The plan provided for no initial reserve fund, and the first audit recorded that no study of future major repairs and replacements had been prepared; ask for the current reserve balance, any study completed since, and the assessment history.

Taxes: A J-51 application was pending at conversion, and Schedule A projected each unit's taxes both with and without the exemption. Model the actual current bill rather than any plan-era figure.

Market read. Most recent trades (2024) cleared a median $1,223/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 3.2% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying

You are buying a condominium in a co-op neighborhood. That is most of the value: right of first refusal instead of co-op board approval, and owner leasing permitted with conditions. Confirm closing timing and entity or trust ownership rules in the declaration, bylaws and house rules.

Reconcile the unit count and read your unit's plan. Twenty-three residential units in city records and in the condominium's own audited statement; twenty-four in the 2008 plan; twenty-five in the architect's project description. Confirm the schedule and common interest for your specific unit against Schedule A.

Reserves and assessments deserve a hard look. No initial reserve fund, no reserve study at inception, and a small unit count mean capital events land heavily. Ask for the reserve balance, the assessment history since 2010, and any engineer's report.

The façade answers to two authorities. The historic district and a private conservation easement both govern the street elevations, and Local Law 11 inspection applies. That protects the architecture and disciplines the capital budget; find out where the building stands in its current cycle.

Model the tax bill, and understand the mixed-use base. The conversion-era application does not establish an award or expiry. J-51 improvement-value exemptions and cost-based abatements have distinct terms; verify the grant certificate and current bill before modeling benefits. A retail unit in the cellar and basement and an office unit at the first floor and mezzanine are part of the condominium, and the plan disclaims any representation about noise or traffic from either.

What to know if you’re selling

Lead with the building, then the apartment. Franklin Trust Company, 1891, George L. Morse, Romanesque Revival, hipped tile roof, Benjamin Franklin over the door. Present those documented architectural details without inferring rarity or a buyer-specific price premium.

State the ownership form and actual rules. Explain deeded ownership and the operative review procedures; confirm entity, trust, pied-à-terre and leasing rules rather than inferring permission from condominium status.

Price on the line, not the building average. A second-floor loft, a balcony unit, an upper-floor three-bedroom and the penthouse are four different products. Anchor to the closest same-line sale and adjust for condition and exposure.

Have the building's papers ready, and photograph the landmark. Current financials, reserve information, the façade easement and the latest Local Law 11 status support buyers’ legal review; providing them early does not prevent renegotiation. The entrance arch and the roofline belong in the marketing above the kitchen.
