There was a partial collapse of a structure under construction in San Francisco's Lower Nob Hill neighborhood Saturday morning.

The structure fell pushing scaffolding to the ground as well.

Fire and police were dispatched to the building at 676 Geary Street around 9:15 a.m. on reports of fallen scaffolding and a partial building collapse, San Francisco fire Lt. Robert Lopez said.

Fire crews arriving on the scene found the partial building and scaffolding collapse knocked down a light post, but did not cause any injuries to the construction crew working there, he said.

Several cars parked in front of the house were also damaged.

Building inspectors and personnel from the San Francisco Department of Public Works were also called to the scene.

It is unclear what caused the structural collapse, Lopez said.
