Founded in 1923, the Joseph J. Duffy Co. has become a specialist in multi-unit residential construction, including affordable multi-family, senior, retirement, assisted, supportive and independent living facilities. We also provide new construction, renovation and construction management services for all types of commercial property types.  Our bonded projects have ranged up to $50 million.

We don't build buildings. We build your building. At Joseph J. Duffy Co., we work with developers, architects, consultants and others to make sure it's the building you envisioned, you planned - and that will meet your design and functional goals and budget.

In that process, we work to make a meaningful and measurable difference in the long and often-times complex building process - from planning to construction to ultimate use. Because we understand that building is much more than construction, we do more than construct a building.

The JJDuffy difference is evident in our
