How does the age of U.S. homes impact renovation spending?
Core argument: Replacement spending reached 49% of all home-improvement outlays, driving a shift toward mandatory maintenance over discretionary upgrades.
49% percent of all improvement spending is now for necessary replacements like HVAC that owners can’t delay, said Rachel Drew, director of Harvard’s Remodeling Futures Program. In 2023, homeowners in the U.S. spent an average of $9,030 on replacement projects such as windows, up 59% from 2009 after adjusting for inflation, said Harvard’s Drew. Financial advisers traditionally suggested setting aside 1% of a home’s value annually for upkeep, but many now argue that isn’t enough. While 1% may cover routine upkeep, 2% to 3% provides a more realistic cushion for expected maintenance, home-improvement projects and unexpected repairs, particularly for older homes, said Angie Hicks, co-founder of home-services company Angi.
