A home undergoing a major remodeling project collapsed late Monday night, tumbling down a hillside in San Francisco's Twin Peaks neighborhood, authorities said.
San Francisco police said they began getting phone calls at about 10:30 p.m. reporting the collapse of the residence in the 100 block of Crown Terrace.
Fortunately, no one was in the home at the time of the collapse. A nearby home, however, had to be evacuated.
The home was owned by San Francisco Port Commissioner Mel Murphy and was in the process of a major expansion from a two-story structure to four stories. Construction crews were in the process of adding 4,000 square feet to the home.
Building inspectors were set to examine the rubble in an attempt to determine the cause of the collapse.
Records show the home was originally built in 1941 and that Murphy had originally sought permission to demolish and replace it with a new structure.
Some tragedies at hospitals might be unavoidable, but a mother and father who lost their 21 month old daughter at Children's Hospital Oakland say it's what happened after their daughter's death that has continued to torment them.
