A Soft-Story building is a multi-story structure built with a first floor that is much less rigid (soft) than the floors above, such as in an apartment with tuck under parking. They can and have failed in significant seismic activity due to un-reinforced openings on the ground floor, which caused far more movement than the soft story building could withstand, resulting in the upper floors collapsing on top of it.


In 2015, the City of Los Angeles signed into law, the Mandatory Retrofit Program under Ordinance 183893, requiring the retrofitting of wood-frame apartment buildings to withstand a major earthquake. Structures that are in danger of catastrophic damage in the event of an earthquake are required to comply with the retrofit ordinance.
