The DeMatteis Organizations

Operating as a fully integrated, full-service enterprise, DeMatteis has the resources and experience to cover the full spectrum of construction and real estate development.

General Contractor:

Leon D. DeMatteis Construction Corporation (LDDCC), the construction affiliate of The DeMatteis Organizations, is responsible for the construction of all DeMatteis sponsored projects. Working closely with our subcontractors to make sure milestones are met, our construction arm is able to deliver time and time again for the owner. “Building Green” has become a prominent aspect in the construction industry, and DeMatteis has been able to showcase its creative problem solving capabilities in working with cutting edge and first of its kind sustainable technologies.

Building Green Projects

Construction Management:

With its owner/developer’s eye for detail, DeMatteis provides an invaluable ingredient to successful development by preparing precise budget estimates and reliable project schedules to preserve the reliability of the largest component of a development budget – “the cost of construction.” By also having some LEED certified personnel, we are able to maintain the strict requirements that follow certain programs to achieve the target rating of a green project.


The DeMatteis Organizations has established itself as a regional leader in middle income and luxury housing, as well as office properties. As owner and developer, DeMatteis has had their finger on the ever-changing skyline of the city. Whether it was numerous successful Mitchell-Lama housing towers to a more recently unique NYCECF “combined occupancy” project that consisted of a luxury residential tower and a middle school on the Upper East Side of Manhattan. DeMatteis has also taken its development expertise out of state and worked successfully with regionally based developers in Virginia, Georgia, and Florida.

Design Build:

Having in-house registered architects on the development team allow DeMatteis to have a significant role in the pre-construction aspect of a development project. Designing and building a structure with the highest and best use in mind, we are able to find the maximum amount of buildable feet for a structure to be successful.

Property Management:

An affiliate of The DeMatteis Organizations, R/Y Management Co., Inc. is one of the premier management companies in the New York metropolitan area. As a privately held, full service property management company, R/Y manages over 10,000 townhouses, rental apartments, cooperatives and condominiums, including numerous affordable residential units for DeMatteis Affiliates and third party owners.

Another wholly owned affiliate, DM Airport, LTD. (DMAL) has operated the Morristown Municipal Airport for over thirty years. Under a unique ninety nine year lease/operating agreement, DMAL is responsible for all facets of the Airport’s operation, management, and development.
