Who's Really Building Brooklyn's Condos?

Condo Book Research · Updated Oct 10, 2026 · 4 min read

Shopping for a new Brooklyn condo? The company behind the building matters as much as the finishes. We read Brooklyn's condo offering plans to see which developers build the most, where, and at what prices.

When you buy in a new condo, you're buying from a sponsor: usually a company set up for that one building. The real question is who stands behind it. The offering plan (the disclosure document every NYC condo sponsor files with the state Attorney General) often says, naming the firm the sponsor belongs to or whose principals run it.

We read Brooklyn's condo offering plans, 4,918 of them, and tied 395 to a named development company. That's 305 companies, and 76 of them have filed for two or more Brooklyn buildings. Here's who they are and what it means for you.

The Most Active Brooklyn Condo Developers

Minerva Capital Holdings leads, with 15 Brooklyn buildings and 67 homes. The ten most active developers account for 22% of the Brooklyn plans we could tie to a company.

Brooklyn Is Built by Small Developers

The busiest developers build small. The median building from the top ten has just 7 homes. These are boutique walk-ups and mid-rise buildings on side streets, not towers. For you, that means fewer neighbors to share costs with, and a first-year budget that leans on each owner more. See how much condo common charges should be.

Who Builds the Big Ones

Count homes instead of buildings and the list changes. RAL Companies & Affiliates is behind 575 homes in just 2 Brooklyn buildings. The developers behind the most Brooklyn condo homes:

• RAL Companies & Affiliates: 575 homes in 2 buildings
• CIM Group: 571 homes in 2 buildings
• Livwrk: 571 homes in 2 buildings
• Douglaston Development: 557 homes in 1 building
• Velin Ventures: 557 homes in 1 building

Big buildings often have more than one developer, so a building can appear under each partner.

Who's Building Now

Since 2021, 1,087 Brooklyn condo plans have been filed or accepted. Minerva Capital Holdings has the most of the developers we could identify, with 10. The most active since then:

Where They Build

The top ten developers' buildings cluster in Park Slope (14 buildings), Bed-Stuy and Bushwick. Many developers stick to one or two neighborhoods they know; the table above shows where each one builds most.

What Buyers Have Paid

Among developers with at least three Brooklyn buildings that have recorded sales, buyers paid the most at Bluefield Holdings's buildings: an average $1,608 per square foot across 7 buildings. That's the closing price recorded with the city divided by the home's size in Schedule A (the plan's list of every unit, its size and the sponsor's price). The Sales & Sellout page has the figures for each building.

What to Check About a Developer

• Who is the sponsor, really? Look in the offering plan's "Identity of Parties" section for the principals and the company they run.
• What else have they built? Visit one of their finished buildings and ask owners how the first years went.
• How did those buildings sell? Check whether earlier buildings closed out or still have unsold homes.
• Are there amendments? Changes to prices, budget or timing are filed as amendments. Ask your attorney to read the latest one.
• Who did they hire? The architect, managing agent and sales team are named in the plan. See whether the developer rehires the same firms.

Common Questions

Who are the biggest condo developers in Brooklyn?

By number of buildings, Minerva Capital Holdings leads with 15 Brooklyn offering plans. By number of homes, RAL Companies & Affiliates leads with 575.

How do I find out who developed a condo building?

Read the offering plan's section on the sponsor and its principals. Each building page on The Condo Book Project shows the developer when the plan names one, with the page it comes from.

Why isn't a developer I know on the list?

Many plans name only people and one-building companies, not a parent firm, so we can't tie them to a developer. Plans whose pages aren't searchable yet aren't included either.

Developers are the companies the offering plan names as behind the sponsor, read from the plan text with the page cited, plus hand-checked entries for large plans; a firm's affiliates are counted together, as on our developers page. Buildings are Brooklyn condo offering plans filed with the NY Attorney General, each counted once; homes are residential units on the plan's AG record. Years are when plans were accepted (or submitted, if not yet accepted). Neighborhoods are NYC Neighborhood Tabulation Areas. Prices are recorded sponsor closings in ACRIS (the city's property records) per Schedule A square foot, for buildings with at least three such sales. Pictures are 3D massing drawings, not photos.
