Their working relationship is a new one for City Hall.
"It's unusual for New York City," said Jamie Chandler, political science professor at Hunter College. "He'll need to be careful. ... She is not mayor, he is. They need to walk a fine line."
De Blasio, an outspoken liberal, ran as the opposite of billionaire Mayor Michael Bloomberg, pledging to listen to the working-class New Yorkers who felt Bloomberg's 12 years in office were biased toward Manhattan elites.
Bloomberg ran the city like the CEO he was, empowering his commissioners and deputy mayors to handle day-to-day operations.
Bloomberg, who never worked in government before taking office in 2002, surrounded himself with like-minded people from the corporate world, who believed that data-driven solutions could be found for most city problems.
That engineer-like approach helped drive down crime and improve most city services, but its implementation sometimes seemed cold.
De Blasio, 52, wants it clear that all lines of authority run to him.
"Having worked in New York City government as long I have, I'm going to take a very hands-on approach," de Blasio said while announcing the first members of his transition team.
He learned his management methods from some of his party's power players. He worked in Bill Clinton's administration, where his boss was Andrew Cuomo, now New York's governor. De Blasio later managed Hillary Rodham Clinton's Senate campaign.
De Blasio's first four appointments to his transition staff three women, two of them minorities were an obvious nod to make his team look like the city it serves. But more tellingly, the way those people were selected revealed the outsized role his wife could play in the administration.
"The people who are standing here are standing here because she and I made that decision together," de Blasio said, "and we'll continue that practice."
