After a major earthquake, many residential tenants are likely to be displaced from damaged buildings. Tenants of soft-story buildings – multi-unit, wood-frame residential buildings with a first story that lacks adequate strength or stiffness to prevent leaning or collapse in an earthquake – are particularly vulnerable. The Mandatory Seismic Retrofit Ordinance requires that older wood-frame buildings with 5 or more residential units that are vulnerable to major seismic events be seismically retrofitted.
