Many pre-1979 houses have a short (less than 4-foot), wood-framed wall surrounding the crawl space under the house. This short wall is known as a “cripple wall.” To help prevent this type of house from sliding off of its foundation during an earthquake, the cripple wall needs to be braced with plywood and the house bolted to the foundation.
