The 58-year-old Lodi driver was hospitalized with a wrist injury and chest pains after the mishap at the Prospect Towers Apartments on Prospect Avenue around 2 p.m., police said.
The driver was backing out of a space when her 2012 Nissan Altima struck a parked car, authorities said.
She then hit the accelerator instead of the brake, sending the sedan through a fence, over a retaining wall, through the parking lot and into a building entrance, where it damaged a support column, they said.
She was brought to Hackensack University Medical Center.
A city building inspector was summoned.
