No one was injured after relatives moved a 94-year-old woman from the Wynnefield property over concerns about a visible crack.
PHILADELPHIA, PA — A home in the city’s Wynnefield neighborhood partially collapsed late Saturday, only hours after a 94-year-old resident left because her family was concerned about the building’s condition, according to city officials and local news reports.
The collapse occurred at the corner of Bryn Mawr and Woodbine avenues on July 25. The roof and part of the front wall came down, scattering debris across the property. No one was inside, and no injuries were reported. Officials ordered the unstable structure demolished, and crews began removing it Sunday morning.
A relative of the woman who had been living in the home said she left earlier Saturday after the family noticed a crack along the front of the building. The Philadelphia Department of Licenses and Inspections said the property’s owner had died and the owner’s grandmother had continued living there until relatives became worried about its structural condition.
One next-door neighbor told WPVI-TV that the resident had moved out only a couple of hours before the collapse. The neighbor said the noise sounded like thunder and shook the adjoining home strongly enough that she checked the weather on her phone.
Local reports gave different times for when the failure began. CBS Philadelphia reported that the house started collapsing shortly after 8:30 p.m., while other reports said emergency crews were called to the intersection at about 11 p.m. Saturday. All accounts agreed that the property was empty when the major collapse occurred.
Inspectors found that the main roof and the front wall of the building had collapsed, according to the Department of Licenses and Inspections. The department placed the property under an emergency demolition order because of what it described as significant structural instability and the need to protect the public.
Philadelphia Gas Works shut off the gas line to the property as crews secured the area. Utility services were also disconnected to reduce risks to firefighters, inspectors and demolition workers. Heavy equipment was brought to the site Sunday to take down the remaining portions of the house.
NBC10 reported that the property had no existing permits, violations or investigations recorded by Licenses and Inspections before the collapse. Officials had not announced a cause as of Monday, and it was not immediately clear how long the crack had been visible or whether the building had received a recent structural inspection.
The collapse alarmed residents in a neighborhood where many homes have stood for decades. Laurie Lindsey, a nearby resident, told NBC10 that the incident was shocking and sad because the house had been there for more than 60 years. Another resident, Carter Borden, told WPVI-TV that the failure made him think about possible hidden problems in other older houses.
State Sen. Vincent Hughes, whose district includes the area, called for a complete investigation. Hughes said findings from the investigation could help officials decide how to address and invest in aging properties throughout the community.
Demolition of the damaged home was underway Sunday, while the cause of the collapse remained under investigation. City officials had not released additional information about the property’s condition or announced whether nearby homes would require structural evaluations.
