Very important. Many older San Francisco homes were built before modern seismic standards and rely on aging foundations or soft-story framing that performs poorly in earthquakes. A retrofit strengthens vulnerable areas and reduces the risk of major structural damage. From a value standpoint, a completed retrofit gives buyers peace of mind, can improve insurability, and is increasingly expected by the market. If a home hasn’t been retrofitted, I help buyers understand what work is needed and how that factors into budgeting, negotiations, and long-term planning.
