Choose DDA because of the quality of the physical plant, the creative structure that gives efficient cost of occupancy, and the hands on approach of property management that makes sure all tenant concerns are addressed. The DDA promise is to provide the most cost effective approach to occupancy costs, while delivering the value a tenant or partner demands.

Just like you, we’re in it for the long term because we are also owner, investor and developer. By not being a public company, we are able to offer tremendous amounts of flexibility to everyone who builds with us. Last but not least, we believe in building businesses as if we’re building a home for all that work there.

Good reputations and good images aren’t cheap—otherwise everyone would have them.

In addition to development, Delle Donne & Associates is a full service asset management organization, which provides property management services for retail, office and industrial properties that are located throughout New Castle County.

As an affiliate to entities that own real estate, DDA is philosophically geared towards ownership management of real estate, maximizing income and protecting asset values. DDA’s objective is to meet the goals of the owner by paying careful attention to detail and understanding ownership circumstances which surround the various projects. We then try to custom tailor our approach to suit their circumstances.

DDA’s management objective is to maximize income through cost control, and maximize revenue through aggressive leasing, while being sensitive to long-term asset values as positive short-term strategic decisions can have negative, long-term consequences. DDA has a thorough working knowledge of the market and is able to provide an optimum balance to short and long term planning.

DDA has managed a real estate portfolio consisting of over 2,000,000 square feet occupied by approximately 200 different tenants. The company employs a full time staff of professionals who provide management, accounting, leasing, financing and construction services.

The company is supported by in-house management personnel whose responsibilities are to:

  • Competitively bid and award all contract services for the properties.
  • Oversee building and grounds maintenance through coordination of manpower and vendor services.
  • Oversee legal, insurance and code compliance.

The financial structure of any given deal must address the cost of the physical plant, as well as the utility to the end user. Delle Donne & Associates has a track record of optimizing these two variables – tenant satisfaction and the cost of occupancy, to ensure our partners jointly benefit as well.
