  "articleBody": "Seismic retrofitting is the process of strengthening an existing building so it better resists earthquake forces, typically by improving the way seismic loads are transferred from the structure to the foundation. California building departments and engineering guidance describe retrofits as reinforcing structural elements so that during shaking, loads are redistributed through shear walls, braced frames, collectors, and properly anchored foundations instead of causing collapse or severe damage. In practical terms, this can include bolting wood sills to foundations, adding plywood shear walls, steel moment frames, column jacketing, diaphragm strengthening, and anchoring parapets. In Los Angeles County, seismic retrofitting is not just a best practice; in several cases it is mandated by local codes and ordinances. The Los Angeles County Building Code includes Chapter 95, which sets requirements for older concrete tilt‑up buildings permitted before April 13, 1975, including structural analysis, anchorage, and strengthening or demolition where deficiencies are found, according to LA County Public Works’ published FAQs. The County has also introduced an ordinance to mandate seismic retrofit of certain high‑rise nonductile concrete buildings in unincorporated areas and County‑owned facilities, requiring structural evaluations and completion of retrofits to minimum safety standards within specified timeframes, as described by the Los Angeles County Board of Supervisors’ public notice. Within the City of Los Angeles, separate from County unincorporated areas, mandatory programs target wood‑frame soft‑story buildings and older concrete structures under specific ordinances and compliance schedules. Local seismic retrofitting policy therefore operates at both the County and city levels and varies with building type, age, and jurisdictional boundaries, which owners and practitioners must verify with the relevant building department before planning a retrofit.",
