Starting out as an apartment building owner and manager in the 1970s, the Katz Group transitioned into single family and multi-family development in the late ‘80s. Over the past 30 years, affiliated companies have developed more than 1,000 single family and multi-family homes and condominiums in eastern Massachusetts and the Seacoast of New Hampshire. Today, the company focuses on multifamily “stacked-flats” close to city centers.  Our mission statement is simple – overbuild each home, sell at a fair price, and deliver an unmatched customer experience. We accomplish this through a high degree of principal involvement and a vertically integrated approach. We procure and permit the land, act as our own general contractor, directly service each of our homes, and participate heavily in the marketing and sales of our homes. Our success and reputation have been established through long standing and unique relationships with our key subcontractors, suppliers and financial partners.
