PORTLAND, Ore.-- Multnomah County Commissioners started the process Thursday of selling the historic downtown courthouse and a building that now houses health services.

A vote to list them officially as surplus properties started the process of selling the buildings.

The courthouse at 1021 SW 4th Ave., built in two phases from 1909 to 1914, is on the National Register of Historic Places. The McCoy building at 426 SW Stark St., was built in 1923.

With the vote triggered a 60-day period of public comment before they go on the market. The county plans an open house in May to explain this process and to take additional comment.

The 292,717 square foot courthouse, built in the neo-classical style, has 39 courtrooms on eight floors. The county determined in 2013 that retrofitting the building to meet earthquake standards was too costly.
