Mountain View FAQ
Why doesn't Santa Clara County require non-ductile concrete retrofits?
The Board of Supervisors has not adopted a mandate. Most affected concrete buildings sit inside cities, not unincorporated land. SB-1078 statewide inventory work is underway and may eventually inform a county or city ordinance.
How do I tell if my building is non-ductile concrete?
Buildings of reinforced concrete frame construction permitted before 1976 are presumptively non-ductile. A licensed structural engineer should confirm using original drawings and FEMA P-154 screening before scoping any ASCE 41-17 evaluation.
San Jose FAQ
Is my concrete building required to retrofit?
Not currently in San Jose. Unlike LA's mandatory program, the city has no compulsory non-ductile concrete retrofit ordinance. Voluntary ASCE 41 evaluations and upgrades are strongly encouraged for pre-1980 concrete frames.
How do I know if my building is non-ductile?
Hire a structural engineer to review original drawings. Pre-1980 reinforced concrete frames without confined column detailing or shear-wall continuity are typical concerns. Tier 1 ASCE 41-17 screening costs $5–15K for mid-size buildings.
