Edison Properties, the privately owned real estate holding and development company that has had a presence in Newark for more than 60 years, officially announced it will be moving its headquarters to Ironside Newark, the former warehouse the company is modernizing into a state-of-the-art office complex.

The move, long expected, will take place in early 2019.

Edison Properties Executive Chairman Robert Selsam said the move reinforces the company’s longtime commitment to Newark.

“Edison Properties traces its beginnings to a single parking lot in Newark more than 60 years ago and has always remained deeply committed to the city’s success,” Selsam said in a statement.

“We are extremely excited to start a new chapter in our company’s history at Ironside Newark and continue playing a role in Newark’s resurgence.”

Edison Properties’ new offices will occupy 39,709 square feet. It is relocating from its longtime office space on Washington Street.

The company began redeveloping the former Newark Warehouse into Ironside Newark — the city’s first speculative office project in more than 30 years — in Spring 2017.

The property has attracted several tenants, including Mars Wrigley Confectionery’s North American headquarters. Its latest tenant, Bloomfield-based law firm Pearlman & Miranda, also was announced Thursday.

Edison Properties said the building’s state-of-the-art loft-style office space is 72 percent leased.
