Design code year

Official standalone inventory of San Francisco tall buildings, focused on attributes relevant to earthquake performance and post-earthquake recovery. It is building/address/representative-parcel pointable and emits structural material/system/type, known seismic-retrofit year, permit-document stamp years, completion year, design-code year, site/foundation information, collection date and primary source. The dataset description says that as of October 1, 2018 it contains the complete 156 buildings taller than 240 feet plus 24 buildings over 160 feet. It is not a mandatory-retrofit compliance register: retrofit_date means a known retrofit year, permit_date fields are document date-stamp years, and completion_date may come from a CFC or Emporis. None proves present resistance or current code compliance.
