CEBC Appendix Chapter A3 contains prescriptive provisions for seismic strengthening of cripple walls and sill plate anchorage in certain light wood-frame residential buildings. The provisions address conditions such as inadequate cripple wall bracing and insufficient sill plate connections. Whether the prescriptive provisions apply to a particular property depends on the building and existing conditions.
Applicability depends on factors such as the building’s construction, foundation system, cripple wall conditions, number of stories, and other project-specific requirements. A property evaluation can help determine whether Chapter A3 provisions are applicable or whether another design or retrofit approach is required.

Some EBB retrofit work uses requirements associated with Chapter A3, but program eligibility and project requirements should be confirmed for the specific property.
