MDG Design & Construction

What MDG Design & Construction does

MDG Design & Construction is a privately held, Woodbury, New York-based affordable housing developer and general contractor founded in 1988. The firm specializes in two core service lines: occupied housing rehabilitation and new construction of multifamily affordable developments. Its flagship offering is occupied rehabilitation, in which residents remain in place during comprehensive unit and building upgrades; MDG deploys four proprietary methodologies for this work — Checkerboarding, Hospitality Suite, Relocation, and Apartment Alter Ego — and claims 23,500+ occupied units rehabilitated at over $3.9 billion in hard costs. Revenue is generated through construction fees, developer fees, and project management services on government-funded housing projects, supplemented by joint venture structures (notably RDC Development with Wavecrest Management) that co-execute PACT/RAD conversions.

The go-to-market is relationship-driven and government-focused. MDG participates in competitive procurements and partnerships with NYCHA, the U.S. Virgin Islands Housing Authority, Troy Housing Authority, and HUD, operating under the federal Rental Assistance Demonstration (RAD) and NYCHA's Permanent Affordability Commitment Together (PACT) programs. Notable projects include Ocean Bay/Bayside Apartments ($560M, completed 2019 — the largest single-site RAD conversion in the U.S.), Williamsburg Houses ($492M, completed 2024), Eastchester Gardens ($391M, in construction), Bay View Houses ($757M financing closed 2025), and Walter I.M. Hodge Pavilion ($116.7M, USVI). The company is family-controlled (Rooney family: Matthew Rooney as CEO, Michael T. Rooney Sr. as Founding Principal), with 101-250 employees and offices in Woodbury. In 2025 alone, it closed financing on over $1.4 billion of concurrent PACT projects, with multiple awards from the New York Housing Conference, NAHRO, AHTCC, Preservation League of New York State, and Novogradac recognizing both project execution and the firm's leadership.

Revenue model

1. Construction and Development Services: MDG serves as the general contractor and developer for affordable housing rehabilitation and new construction projects. Revenue is generated through construction fees, developer fees, and project management services on government-funded housing projects through PACT/RAD programs.
2. Joint Venture Partnerships: MDG forms joint ventures (such as RDC Development with Wavecrest Management) to undertake PACT projects. These partnerships allow the company to share risk and reward on large-scale redevelopment projects.
3. Property Rehabilitation (RAD/PACT Program): Revenue generated from comprehensive renovations of public housing properties through the federal Rental Assistance Demonstration program, where private developers partner with housing authorities to fund repairs using private capital.
