An earlier post described how the top 10 builders1 in the country captured a record 44.7% of new single-family closings in 2024. BUILDER Magazine has now released additional data on the top ten builders within each of the 50 largest new home markets in the U.S., ranked by single-family permits. It is important to note that this post does not focus on the top ten largest home builders nationally; instead, it analyzes the top ten list within each of the largest 50 new housing markets. The 2024 data show that the top 10 builder concentration in the 50 largest markets ranged from 38.9% in Kansas City, MO-KS to 97.8% in Cincinnati, OH. In 11 metro areas, the top ten builders’ market share exceeded 90%. Across all 50 metro areas, the average market share of the top 10 builders was 79.3%, up from 78.2% in 2023.
