SAN FRANCISCO (KCBS) – Owners of so-called ‘soft-story’ building, prone to being severly damaged in an earthquake, can expect to be hearing from the city of San Francisco over the next few months.
In April, San Francisco formally adopted a strict retrofit law; it applies to an estimated 3,000 buildings deemed prone to collapse in a major earthquake. More specifically, the subject properties were built before 1978, stand at least three stories high, and are comprised of five or more dwelling units.READ MORE: UPDATE: Judge Denies Bail for Los Gatos Mom Accused of Hosting Drunken Teen Sex Parties
Such structures are referred to as soft-story buildings. They are made of wood framing and generally include a garage, large windows or similar ground floor openings.
The concern is that, in an earthquake, the bottom floor of a soft story building won’t withstand the shaking, allowing the building to collapse or “pancake.”
