What Retrofit?
November of 2015, the Los Angeles City council adopted ordinance No. 183893, creating mandatory standards for earthquake hazard reduction in wood frame buildings with soft, weak, or open-front walls and non-ductile concrete buildings built prior to 1978. This ordinance was put in place after a series of collapses of multifamily apartment complexes, beginning with the collapse of the Northridge meadows in 1994. If a permit for the construction of a new building was applied for before January 1978, the city concludes that the ground floor, or "tuck under" portion of the structure contains open floor space, such as parking, that causes soft, weak or open-front wall lines, therefore requiring a seismic retrofit.
