Second Home Areas Gaining Home Building Market Share
According to NAHB, NAHB’s featured topic for the second quarter HBGI reveals that 17.5% of single-family and 8.6% of multifamily construction takes place in second home areas. Recent NAHB analysis found that the total count of second homes across the US was 6.5 million, which accounts for 4.6% of the total housing stock. For this analysis, a second home area is a county that has a second home share greater than 10.3% of the county’s total housing stock (these counties fall within the 75th and above percentile of the second home stock share distribution). There are 788 counties that are considered a second home area based on this definition.
Single-family
Single-family permit data shows that the market share for construction in second home areas has grown by over four percentage points in the past nine years. The earliest data, which is the fourth quarter of 2015, shows that second home areas had a market share of 13.2%. As of the second quarter of 2024, the market share for this geography increased to 17.5%. However, this latest reading is down from a peak of 18.3% in the first quarter of 2023.
The peak growth rate in construction for second homes areas was at 38.5% in the third quarter of 2021. The first recorded decline in the growth rate occurred in the third quarter of 2022. This downward growth rate was followed by five quarters of declines until the first quarter of 2024. Second home areas have averaged a growth rate of 9.1% between the fourth quarter of 2015 and the second quarter of 2024, while non-second home areas averaged single-family a growth rate of 5.1% over the same period.
Multifamily
Although smaller, the market share for second home areas has also grown for multifamily construction. The market share was 5.5% in the fourth quarter of 2015 and is now 8.6%, a 3.1 percentage point increase. This increase in market share has been more volatile than single-family, as growth in construction has not been as consistent for multifamily in second home areas.
There have been three periods where construction growth for multifamily experienced declines in these areas, such as in 2017 and early 2021. The third period of decline is ongoing, as there have been two consecutive quarters where the growth rate has been negative to start 2024. The latest growth rate is a11.8% decline. This is down from a peak of 53.1% in the third quarter of 2022, as multifamily construction has slowed nationwide.
