One of Wisconsin's largest privately held companies — owned by politically active billionaire Diane Hendricks — plans to open its first Milwaukee location on the city's far northwest side.

ABC Supply Co. plans to lease a building at 11200 W. Heather Ave. for a 61,900-square-foot distribution center with a 6,200-square-foot office.

Beloit-based ABC Supply, which sells roofing, siding and other building materials, plans to initially have 15 to 25 employees at the operation, located within Towne Corporate Park-Granville business park.

That workforce could eventually expand to around 30 employees, said Dan Jeziorski, an ABC Supply real estate asset manager.

The company plans to lease the building for 15 years, with around $1.5 million in renovations happening at the property, Jeziorski said at a Monday Plan Commission hearing.

The commission approved plans for the site, which will include an outdoor storage area.

The building was previously leased to a mechanical heat-treating company and has been vacant for three years.

ABC Supply is No. 2 on this year's Wisconsin 75.

The Wisconsin 75 is an annual list of the state's 75 largest private and closely held companies ranked by revenue. The list is prepared by consulting firm Deloitte.

The companies are ranked by annual revenue, with Milwaukee's Northwestern Mutual Life Insurance Co. the top-ranked listing.

ABC Supply has around 800 locations nationwide totaling more than 14,000 employees, Jeziorski said.

Hendricks is the company's co-founder. She is known for her philanthropy as well as making large donations to Republican political candidates.
