What Ginsburg Development Companies does

Ginsburg Development Companies (GDC) is a family-controlled, vertically integrated real estate development company founded in 1963 by architect Martin Ginsburg and headquartered in Valhalla, New York. The company designs, builds, owns, and manages a portfolio of luxury residential rental communities, commercial properties, and a boutique hospitality asset across Westchester and Rockland Counties in the Hudson Valley region of New York. GDC's residential rental portfolio comprises approximately 1,900+ units across 14+ properties ranging from 36-unit boutique buildings to a 330-unit flagship (River Tides at Greystone), all positioned along the Hudson River waterfront or adjacent to Metro-North train stations. Commercial holdings include the 50 Main office building (95% leased), 11 Martine (anchored by the Westchester County Department of Health), a medical office building (984 Associates), and retail centers totaling more than 416,000 square feet.

GDC operates as its own general contractor and maintains in-house property management through GDC Property Management, enabling vertical integration across the development lifecycle. Its commercial revenue stream is anchored by long-term office leases to government and private tenants, while the residential segment provides distributed recurring rental income at market-leading rents. The hospitality vertical, established through the redevelopment of the former St. Mary's Convent into The Abbey Inn & Spa in Peekskill (including the Apropos farm-to-table restaurant), generates additional revenue from hotel stays, dining, weddings, and corporate events. The company has also expanded into for-sale housing with Stone Hollow at Cornwall (29 homes, 2022), signaling modest product-line diversification.

GDC's go-to-market relies on direct leasing through in-house teams, a dedicated GDC Rentals website (gdcrentals.com), and brand recognition reinforced by four consecutive years of Westchester Magazine "Best Residential Apartment Developer" recognition (2020-2023) and prior National Association of Home Builders design awards. The company is privately held, has no disclosed institutional investors or funding rounds, and continues to be led by founder Martin Ginsburg, with active expansion underway through Bridgewater North (208 units) targeted to begin construction in 2026.

Broad incumbents

• The Related Companies: Large, vertically integrated real estate developer active across luxury residential, commercial, and mixed-use developments in the New York metro area and nationally. Comparable to GDC as an integrated owner/developer/manager in NY multifamily and mixed-use, though at much greater scale and geographic breadth.
• AvalonBay Communities: Public multifamily REIT with deep NYC metro and Hudson Valley exposure operating Class A rental apartment communities. Comparable to GDC in the premium garden-style and mid/high-rise multifamily niche on a regional basis, though at significantly larger scale and as a public REIT.
• Equity Residential: Public multifamily REIT concentrated in coastal urban markets including NYC metro, focused on high-quality rental apartments. Comparable to GDC's Class A urban and suburban luxury rental product in the Northeast, though at much larger scale.
• Toll Brothers: National luxury homebuilder (and via Toll Brothers Apartment Living, luxury multifamily developer/operator) active in the Northeast including NY/NJ/CT. Comparable on luxury positioning and multifamily development in Westchester-adjacent markets, though primarily a for-sale builder rather than rental operator.
• Brookfield Property Partners: Global real estate owner/operator with major office, retail, and multifamily assets including significant NY metro holdings. Comparable to GDC's diversified residential/commercial portfolio and vertical operating model, though at vastly larger scale and global reach.
• Greystar Real Estate Partners: Largest US multifamily property manager, developer, and operator with active NY metro presence. Comparable to GDC's in-house property management capability and resident-service orientation across luxury apartments in the Northeast.

Direct peers

• L+M Development Partners: Privately held NY-based real estate developer of mixed-income, market-rate, and affordable multifamily and mixed-use properties across the NY metro. Comparable to GDC as a regional NY metro developer/owner focused on multifamily and mixed-use, with a similar private operating model.
• LCOR: National real estate investment, development, and management firm focused on multifamily and mixed-use assets in transit-oriented and urban infill locations. Comparable to GDC's transit-oriented, water-adjacent luxury multifamily strategy and vertical integration model.

Regional players

• Vornado Realty Trust: NYC-focused REIT anchored by Class A office and high-end retail in Manhattan. Comparable to GDC's ownership of premier Westchester County office product (50 Main) and downtown White Plains positioning, though concentrated in Manhattan rather than the northern suburbs.

Others

• Simon Property Group: Largest US REIT focused on retail real estate including regional malls and lifestyle centers. Comparable only loosely — to GDC's retail holdings (Mount Vernon South/North big-box centers) — given Simon's pure-retail focus and REIT structure vs. GDC's integrated operating model.
