University's recent sympathetic restoration of its similarly challenging Brutalist landmark, the Art and Architecture Building by architect Paul Rudolph. In 2009 a major exhibition of the original design drawings for City Hall, now part of the archive of Historic New England, was mounted at the Wentworth Institute of Technology. In 2015, Boston Globe columnist Dante Ramos wrote that "if we see the enduring value in Heroic-era architecture, we can also hope for a measure of boldness — and recognize the downside of being too timid." A 2019 essay by Anthony Flint argued that City Hall is "an elegant, successful work of architecture." In 2019, a commemorative pin was produced in honor of the building's 50th anniversary. In an essay written during the anniversary year, architect Aaron Betsky wrote that City Hall "is one of the last concrete examples of government willing to fight for what it thinks is right, which is, or should be, or common good."

The changes in style coincided with political changes, as Kevin White's mayoral administration ended. Under subsequent administrations, which focused on neighborhoods rather than the center city, and decentralization instead of centralized civic power, funding was funneled away from City Hall.
