This appendix compiles four reference guides on the life expectancy of common home building materials and components, including studies from the National Association of Home Builders, Fannie Mae, and the International Association of Certified Home Inspectors. The materials cover expected useful lifespans ranging from 5 to 100 years for items such as roofing, flooring, and mechanical systems. These references are intended to support housing assessments and affordable housing planning decisions.
