The Wolff Co. has relocated its downtown offices and has sold the Argonne Commercial Center to another real estate investment group, says Aaron Lake, a real estate broker who has handled a number of recent transactions involving the Wolff Co. and current and former Wolff Co. properties.

The Wolff Co., a prominent real estate development company with Spokane roots, has leased 3,900 square feet of office space on the eighth floor of the Washington Trust Financial Center, at 717 W. Sprague, where it has moved its Spokane operations from smaller quarters at 220 W. Main, Lake says.

“The Wolff Co.’s move into Class A space is intended to accommodate expected growth,” says Lake, who is based in the Spokane office of Seattle-based commercial real estate brokerage Leavitt Capital Cos.

Commercial real estate agents Cody George and Doug Dittamore, both of the Spokane-based brokerage Kiemle & Hagood Co., represented Washington Trust Bank in the transaction, Lake says.

In a separate transaction, Hovde Orchards LLC has bought the three-building, 137,400-square-foot Argonne Commercial Center, at 9514 E. Montgomery, Lake says.

Hovde Orchards, which is headed by David Hovde and Gerald Hovde, of Ephrata, Wash., paid $3.4 million for the complex, state and county records show.

Leavitt Capital became active in the Spokane market in 2013 when it bought the 500,000-square-foot Central Business Park, at 11016 E. Montgomery, from the Wolff Co. and took over management of the Wolff Co.’s remaining nonresidential commercial properties in Spokane.

At the Central Business Park, Leavitt recently negotiated a lease for 15,000 square feet of space that will be occupied by Bismarck N.D.-based Harlow’s Bus Sales. That company sells and services school buses and provides transportation services to school districts.

Lake and Earl Engel, of the Spokane-based brokerage NAI Black, negotiated the lease.

In another transaction involving a Wolff Co. property, Innovel Solutions Inc., a Chicago-based logistics services provider, has leased 21,700 square feet of space in the Aero Road Business Center, at 10424 W. Aero Road, and the company has moved its Spokane office there from a smaller space in the Spokane Business & Industrial Park, at 3808 N. Sullivan Road.

Lake says Innovel Solutions had done business as Sears Logistics Inc. prior to the move.

Grant Person and Darren Slackman, both of NAI Black, also were involved in the Innovel lease negotiations.

Also at the Aero Road Business Center, 509 Inc., a branded snowmobile video and accessories seller and distributor, has expanded, leasing 2,000 square feet of office space to bring its total space there to more than 30,000 square feet, Lake says.

He adds that Riverstone Residential Group LLC, a Dallas-based apartment-management company, has leased 3,100 square feet of office space in the Wolff Co.-owned Hutchinson Office Building, at 1825 N. Hutchinson, and plans to move its Spokane office there from smaller quarters at 220 W. Main.

Alvin J. Wolff founded the Wolff Co. here in 1948. The company moved to Scottsdale, Ariz., in 2000.

The company currently is focusing on developing and managing multifamily properties, rather than nonresidential commercial properties.

In recent years, the Wolff Co. expanded its apartment holdings here when it developed the $24 million, 216-unit River House apartment complex in Spokane Valley and the $25.7 million, 256-unit Pine Valley Ranch Apartment complex just south of Spokane Valley.
