Soft Story Seismic Retrofit

On October 9, 2015 Los Angeles City Council adopted Ordinance No.183893 - Amending Division 93 and 95 of Article I of Chapter IX of the LAMC to establish mandatory standards for earthquake hazard reduction in existing wood-frame buildings with soft, weak, or open-front walls and existing non-ductile concrete buildings, and amending Sections 152.02, 152.04, 152.05 and 152.08 of Article 2 of Chapter XV of the LAMC to grant authority to the Rental Adjustment Commission to modify Tenant Habitability Program requirements for purposes of implementing seismic retrofit mandates. Ordinance has been in effect since November 22, 2015.

 

An example of a building containing a soft story would be a wood-frame building with more than one story that typically has extensive ground story windows, garage doors, or open-air spaces such as parking or other similar open floor plan with little or no enclosing solid wall, that lead to a relatively soft or weak lateral load resisting system in the lower story. We are FEMA trained and a preferred contractor for California's Brace&Bolt program.
