Local Design Conditions

  • Seismic Design Category D — shear wall and holdown detailing must be explicit on the sheets.
  • Liquefaction-susceptible zones exist in parts of the city and can trigger a geotechnical requirement.
  • Much of the housing stock predates current code, so retrofit detailing is often part of the scope.
