BEAVER DAM, Wis. (AP) — The former MetalFab property in Beaver Dam will be auctioned next month. Dodge County has owned the 140,000-square manufacturing plant since 1995 after foreclosing on it to satisfy tax liens. MacFab Metal Products has been leasing the building since 2006. But, county administrator James Mielke says it owes the county past due rent. It vacated the building last month. The property will be placed on Wisconsin Surplus Online starting around April 7th and ending a month later. The sale of the building is subject to county board approval.
