Altadena FAQ
Why doesn't LA County require non-ductile concrete retrofits?
The Board of Supervisors has not adopted a mandate. Unincorporated areas have fewer affected buildings than LA City, and LACoDPW prioritized soft-story and URM programs first. Voluntary evaluations remain encouraged.
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.
