A Landmark Brooklyn Heights Building Becomes 61 Condos at 98 Montague Street

Nov 1

98 Montague Street, the former Hotel Bossert, is a 1909 building on Brooklyn Heights' main commercial street being converted into 61 condos, about a 4-minute walk from the N and R at Court Street. The developer is SomeraRoad. It's far larger than the boutique buildings I usually track, and large condo offerings almost never come up in Brooklyn Heights.

Where Things Stand

The offering plan for 98 Montague Street was submitted to the New York State Attorney General on June 3, 2026, and is awaiting acceptance. No homes are for sale yet, there is no public pricing, and reservations can't be taken. Across the 54 Brooklyn projects I've tracked from filing to acceptance since 2023, most were accepted 5 to 9 months after filing (about 7 and a half months on average), which points to acceptance between roughly November 2026 and March 2027. In October 2026, a new DOB job was filed to convert the existing 14-story hotel into residences with a one-story addition, so construction still has a way to go after acceptance. Given the scale, expect a longer, more structured sales rollout when it begins. Join my early access list below and you'll hear about pricing and launch timing before it reaches StreetEasy.

What We Know So Far

Likely mix: a range of sizes including three- and four-bedroom homes. The final mix comes with the accepted plan.

What's next: Attorney General review typically takes several months, and pricing becomes public at acceptance.

Buying in a New Development?

New construction works differently than a resale: offering plans, sponsor contracts, closing costs and timelines all have their own rules.

A Closer Look at the Building

At 61 homes, this is not a boutique building, and that's what makes it notable for Brooklyn Heights, where most new condos come as two to four homes inside a townhouse. A building this size likely means an elevator, staff and shared amenities, though the full amenity package isn't public yet. SomeraRoad is developing the project. The plan will confirm finishes, common charges and the final unit mix.

Brooklyn Heights Highlights

Brooklyn Heights is the borough's most historic neighborhood and home to New York City's first designated historic district. The Promenade and its harbor views, tree-lined streets of 19th-century townhouses, and quick access to Downtown Brooklyn and Lower Manhattan make it one of the most enduring addresses in the city.

The N and R at Court Street, about a 4-minute walk
The 2 and 3 at Clark Street, about 5 minutes, and the 4 and 5 at Borough Hall, about 7 minutes
The A, C and F at High Street and Jay Street-MetroTech, a short walk away
Montague Street shops, the Promenade and Brooklyn Bridge Park, all at the door

Katie's Take

I track every new development filing in Brooklyn, and here's how this one compares: every other condo filing in Brooklyn Heights right now is two to four homes in a townhouse, like 103 Joralemon Street and 138 Joralemon Street, while this one has 61. That scale means a real range of layouts and likely an elevator and amenities, which the townhouse conversions can't offer. If you want Brooklyn Heights without a walk-up, this and 205 Montague Street are the two buildings to follow.
