As a general rule of thumb, homes built after 1990 are considered newer, and homes built before 1920 are considered “old” or “antique.” But housing age is a subjective condition that turns on numerous factors.
America has lots of old houses. According to HUD’s 2013 American Housing Survey, the average owner-occupied structure is about 37 years old. For reference, that’s higher than the U.S. median age.
In some parts of the country, the housing stock is far older. On average, owner-occupied housing in Utah is more than 43 years old. Though there are exceptions to the rule, homes tend to be older throughout the Northeast and Midwest, and in urban cores across the country.
By contrast, newer homes and bona fide new construction homes are more common in Southern and Western cities in general, and in suburban and exurban communities across the country.
