The giant Robert C. Weaver Federal Building has been HUD’s headquarters since it opened on Sept. 9, 1968. On Wednesday, HUD Secretary Scott Turner announced an end to that chapter, citing “serious concerns” with the building, including “health hazards, leaks, and structural and maintenance failures.”
