MDG is your complete solution for affordable housing.

MDG Design & Construction is a leading affordable housing-only contracting and development firm specializing in the rehabilitation and new construction of affordable residential apartment buildings. Since 1988, MDG has completed over 900 buildings, 23,500 units, and invested over $3.9 billion in NYC's underserved communities – all affordable housing – and has completed 46 Low-Income Housing Tax Credit (LIHTC) projects, totaling more than 10,000 units. Currently, MDG has over $10 billion and over 5,000 affordable housing units in predevelopment; three projects in construction with 2,000+ historic tax credit units; and three projects in design/development with 2,500+ historic tax credit units, including NYS Housing Finance Authority's first historic lease pass through deal.

MDG combines the experience of many decades of affordable housing development and construction with the nimbleness, flexibility, ease of decision making, and motivation of a tightly held owner-operated business. Michael Rooney Sr. and Nicola DeAcetis, the founders of MDG, have been and continue to be involved in every single project, along with CEO Matthew Rooney, bringing their expertise and leadership to the development team.

Because of the direct ownership and involvement of the MDG principals, we are always focused on the extreme long-term across all elements of a project, our reputation, and our relationships. As a for-profit firm with a “double bottom line,” the success of MDG is evidence that doing the right thing by our partners and our residents is also the right business decision.


MDG’s quality is unparalleled.

At MDG, we are committed to excellence at all stages of our business. From personalized service for our tenants and partners to high quality, market-rate finishes at our developments, we create homes that our residents are proud to live in.

In an ever-evolving world, we pride ourselves in conducting business with the highest degree of integrity and ethics, safeguarding our workers, and ensuring that those we work with, including subcontractors and vendors, uphold our standards. As such, we have developed and instituted state-of-the-art wage compliance monitoring programs—the strictest in the City—that are now the standard in the governmentally assisted construction industry.


MDG puts people first.

MDG was formed in 1988 by our two principals, driven by a genuine passion to create affordable housing that low-income New Yorkers would be proud to call home.

Today, whether creating homeownership opportunities or rescuing distressed buildings, the people-first philosophy inspired by our principals almost 30 years ago continues to guide MDG’s work, allowing us to successfully restore neighborhoods and improve the lives of residents.

  • Open-door approach: We take care of our residents by proactively soliciting feedback and listening to their concerns to meet their needs and create homes they love.

  • Partner collaboration: We put our partners’ needs first, identifying their priorities, presenting holistic solutions, preparing for any contingencies, and advising on the best course of action.

  • Dedication to staff and community: We treat our staff like family by providing job opportunities, a supportive work environment, and training in the neighborhoods where we work. Through extensive community outreach, we hire locally and are a leader in hiring MWBEs for our projects.
