Santa Clara County has no mandatory retrofit ordinance for non-ductile concrete buildings in unincorporated areas. The County Office of Emergency Services maintains a voluntary inventory and supports ASCE 41-17 evaluation, while no countywide mandate parallels San Francisco or Berkeley.
Non-ductile reinforced concrete buildings constructed before the 1976 Uniform Building Code are recognized as a major seismic risk in the Bay Area, sitting near the Hayward, San Andreas, and Calaveras faults. Unlike San Francisco's Mandatory Soft Story Program or Berkeley's evaluation ordinance, Santa Clara County has not adopted a mandatory non-ductile concrete retrofit timeline for unincorporated areas. The County Office of Emergency Services and Department of Planning and Development encourage voluntary screening using FEMA P-154 rapid visual screening and ASCE 41-17 Tier 1-3 analyses. Title B governs the permit process when retrofits proceed. Cities like San Jose are evaluating their own potential mandates separately under SB-1078 inventory work.
No retrofit mandate means no penalties for non-ductile buildings as such. Owners face liability exposure after a damaging earthquake under California premises-liability law, and lenders or insurers may require evaluation as a condition of financing or coverage.
