The building, 285 Madison Ave., partially reopened on Jan. 3 after Hart, 44, was crushed to death on Dec. 14, but the lower floors remained closed while repairs were made on the elevator that killed Hart and an investigation was conducted.
Some employees at Y&R — which set up in temporary offices on Park Avenue — started working in the building again in early January, but the company reportedly moved all employees back into their offices over Presidents Day Weekend.
“It's actually nice being back because it's our home and familiar and everything," a Y&R employee told NY1. "There's a lot of still sadness and everything, but I think within time that things are going to be a little bit more normal."
Y&R, which owns the building, was hit with 11 Department of Buildings violations after the incident.
The building has had 56 elevator violations since 1989, according to the DOB's website.
