Second Home Areas’ Share in U.S. Housing Construction
The National Association of Home Builders (NAHB) reports that in the second quarter of 2024, second home areas accounted for 17.5% of single-family and 8.6% of multifamily construction. Recent NAHB research shows there are approximately 6.5 million second homes in the U.S., making up 4.6% of the total housing stock. For this analysis, “second home areas” are defined as counties where second homes represent more than 10.3% of the total housing stock, placing them in the top 25% of counties nationwide. A total of 788 counties fall into this category.
Single-Family Construction Trends
The market share of single-family construction in second home areas has increased by more than four percentage points over the past nine years. In the fourth quarter of 2015, second home areas had a 13.2% share of the single-family market, which rose to 17.5% by the second quarter of 2024. This figure is slightly lower than its peak of 18.3% in the first quarter of 2023.
The growth rate for single-family construction in second home areas hit its highest point in the third quarter of 2021, reaching 38.5%. The first decline in growth was recorded in the third quarter of 2022, followed by five consecutive quarters of decreases until early 2024. Between late 2015 and mid-2024, single-family construction in second home areas had an average growth rate of 9.1%, compared to 5.1% in non-second home areas.
Multifamily Construction Trends
While smaller, the multifamily market share in second home areas has also grown, rising from 5.5% in late 2015 to 8.6% in mid-2024—an increase of 3.1 percentage points. However, growth has been less consistent than in the single-family sector, with several periods of decline, including in 2017, early 2021, and the start of 2024. The most recent data shows an 11.8% drop in growth, down from a peak growth rate of 53.1% in the third quarter of 2022, indicating a slowdown in multifamily construction nationwide.
