The following chart is excerpted from a publication by the International Association of Certified Home Inspectors (InterNACHI) containing the life expectancy of nearly every imaginable home component and home system.
Keep in mind this is only a guide. The estimates below (in years) and actual life expectancy may differ drastically depending upon a number of factors including environment, if regular maintenance has been performed and average wear and tear.
A printable PDF file containing the chart below can be found here. The file also contains a “Home Pitfalls by Decade” chart showing typical home issues observed in homes of different ages.
