For the past year-plus that I’ve been commuting to downtown, I had often admired this trim little building standing by itself on a trapezoidal pentagonal lot on the northwest corner of 9th Street and Massachusetts Avenue, N.W. A plaque at the corner identifies it with the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada.
Alas, last week I noticed construction fencing walling off the building. The lights were still on inside the building, but I feared that it would soon go under the ball. The Circulator stop out front has been decommissioned.
That seems less likely, since the building is listed (item 74002154) in the National Register of Historic Places as the American Federation of Labor building. The Sullivanesque edifice was built in 1915 by Milburn, Heister & Company, and served as headquarters for the AF of L for 40 years until its merger with the CIO, at which point the plumbers moved in.
The United Association is now headquartered in Annapolis. I didn’t track down the current owner or tenants.
