The crash happened on 4th Avenue and East 26th Street around 7 a.m.
It appears the bus hit a small one-story commercial building on a local street in a residential neighborhood.
Officials say the bus was on a hill and slid backward due to ice, crashing a rug business called the Barefoot Rug Company.
The driver, who was the only one on board, sustained minor injuries.
The bus was operating on the 704 line, a local line through Bergen and Passaic counties. It was at the end of its route.
The buildings department will evaluate the structural integrity of the building.
