For nearly three decades, Stagg Group has steadily grown into one of the most capable and respected real estate organizations in the New York metropolitan area. What began as a hands-on development effort focused on small multifamily projects has evolved into a fully integrated real estate powerhouse, one defined by scale, long-term thinking, and a deep commitment to community.
That growth has been entirely organic. Built project by project and neighborhood by neighborhood, Stagg Group’s trajectory reflects a disciplined approach to development, grounded in experience and guided by the belief that real estate can and should strengthen the communities it serves.
From Modest Beginnings to Metropolitan Scale
Stagg Group’s story began in the mid-1990s, when founder Mark Stagg launched the company with a focus on small multifamily residential projects. Those early developments were grounded in practical experience and a deep understanding of local housing needs, particularly for working families throughout New York City.
By the early 2000’s, under Mark Stagg’s leadership, the firm had formalized and expanded its operations, setting the stage for what would become a period of sustained growth and increasing complexity. Over time, Stagg Group transitioned from smaller projects to large-scale developments that require sophisticated planning, financing, construction, and long-term operational oversight.
Today, Stagg Group oversees approximately 2 million square feet of residential housing and manages more than 5,000 apartments across New York City and Westchester County. Its portfolio includes affordable housing, workforce housing, and market-rate residences, as well as select commercial, educational, and governmental projects. The company now routinely delivers developments with hundreds of units at a time, projects that demand both technical precision and a strong sense of stewardship.
A Vertically Integrated Platform Built for Scale
One of Stagg Group’s defining strengths is its vertically integrated structure. Unlike firms that outsource major components of the development process, Stagg Group manages projects end-to-end, with in-house expertise spanning development, construction, and property management.
This integrated approach allows the company to maintain high standards at every phase of a project’s lifecycle. From site acquisition and financing to construction execution and day-to-day property operations, Stagg Group’s teams collaborate closely to ensure efficiency, accountability, and long-term performance.
Just as importantly, vertical integration allows the firm to remain deeply responsive to residents’ needs. Property management is not an afterthought, it is a core competency. Stagg Group’s management teams focus on creating well-maintained, professionally operated buildings where residents feel supported, heard, and secure.
Strategic Partnerships and Collaborative Development
As Stagg Group has grown, so too has its ability to collaborate successfully with other leading real estate organizations. In recent years, the firm has become a sought-after development partner, working alongside prominent entities to deliver high-impact projects that serve both public and private needs.
A notable example is Stagg Group’s partnership includes their work on the new Westchester Family Court Building on Garden Street in New Rochelle. This modern civic facility represents a significant public investment and reflects Stagg Group’s capacity to execute complex governmental projects with multiple stakeholders.
In addition to the courthouse, the partnership also includes a major residential tower on an adjacent property, further demonstrating Stagg Group’s versatility and its ability to deliver both civic and residential developments at scale. These collaborations underscore the firm’s reputation as a reliable, capable partner for projects that require deep experience and disciplined execution.
Leadership Recognized Across New York
Mark Stagg’s leadership has not gone unnoticed. Over the years, he has been named multiple times to City & State’s Bronx Power 100 and Westchester Power 100 lists, recognitions reserved for individuals who exert meaningful influence on the economic, civic, and development landscape of their regions.
These honors reflect not only Stagg Group’s scale and success, but also Mark Stagg’s long-standing engagement with the communities where the firm operates, as well as his role in shaping housing and development outcomes across New York.
Commitment to Community and Philanthropy
Beyond development, Stagg Group is deeply committed to giving back. The firm and its leadership have consistently supported local nonprofits and charitable initiatives, including the Juvenile Diabetes Research Foundation and a wide range of community-based organizations. Stagg is widely known and beloved for their frequent initiatives supporting their local communities, including their annual Thanksgiving Turkey Giveaways, that have grown in scale over the decades, to now support many thousands of people every year.
Most recently, Stagg Group and Mark Stagg were honored for their support of March of Dimes, helping raise more than $1.3 million at the 2025 March of Dimes Real Estate Awards Breakfast. The recognition highlighted the firm’s belief that success carries responsibility, and that strong communities are built through both housing and humanitarian investment.
Looking Ahead
As Stagg Group looks to the future, its path forward is defined by experience rather than ambition alone. With decades of institutional knowledge, a fully integrated operating platform, strong development partnerships, and a deep bench of professionals, the firm is well positioned to continue delivering high-quality housing and impactful projects throughout the New York region.
Yet despite its growth, Stagg Group has retained the values that shaped its earliest work: attention to detail, respect for residents, and an understanding that real estate development plays a lasting role in people’s lives.
After nearly thirty years, Stagg Group stands as a model of steady, purpose-driven growth—building not just buildings, but enduring communities and partnerships across New York.
