Adams Slavin was hired to undertake a $24 million renovation of the building's interior. As part of the renovation, corridors were narrowed and partitions between offices were removed to create more office space; vinyl floor tiles and recessed lighting were installed; and the outdated plumbing system was replaced. The project increased interior capacity to 6,500 employees. During this time, Civic Fame was also renovated. The building had been cleaned by 1975 at a cost of $300,000, though more funds for the renovation had also been appropriated. A piece of granite fell from the Municipal Building in 1987, landing on a ramp on the Brooklyn Bridge, although no one was injured. However, a subsequent investigation found other loose rocks on the facade, and as a result, netting was placed on the facade. In 1988, workers began placing scaffolding along the building's entire facade in preparation for the first large-scale restoration of the facade, which was to begin the next year. The renovation was expected to cost $58 million and required of steel tubes to support the massive scaffolds. The facade restoration was undertaken by the architects Wank Adams Slavin. Another restoration of Civic Fame took place during this time. On October 14, 2015, the building was renamed after David N. Dinkins, New York City's first African-American mayor.

These include the large gilded Civic Fame statue at the top of the building; smaller sculptural groups; and plaques and coats-of-arms representing the various governments that have ruled Manhattan.

The statue is a gilded copper figure, made from about 500 pieces of hammered copper executed by the Manhattan firm of Broschart & Braun. The statue is variously reported to be supported on an iron skeleton and made over a steel frame. Civic Fame has been variously described as the largest or second-largest statue in Manhattan, depending on whether the larger Statue of Liberty is considered as being in Manhattan. It is similar in style to the Statue of Liberty. The statue was designed by Adolph Alexander Weinman (1870–1952). It was commissioned by New York City at a cost of $9,000 () to celebrate the consolidation of the five boroughs into the City of New York. The figure—described as "graceful and unusually charming"—is barefoot and balances upon
