The Trump administration is offering the Washington, DC headquarters of the Department of Housing and Urban Development for sale as it seeks to reduce its real estate footprint for a shrinking federal workforce.

The federal housing agency says its 1968 building faces more than $500 million in deferred maintenance. It also says current staff take up only half the space.

Even with HUD employees returning to the office full-time, the department’s Brutalist headquarters is only half-occupied.
