The custom home market is not as heavily impacted by the interest rate cycle in comparison to other forms of homebuilding, making it a relative bright spot in residential construction. While overall single-family construction has been down 5% for the first four months of 2026, custom homebuilding is providing relief in the homebuilding.
According to the National Association of Home Builders’ (NAHB) analysis of Census data from the Quarterly Starts and Completions by Purpose and Design survey, there were 36,000 total custom building starts during the first quarter of 2026. This is up 3% relative to the first quarter of 2025.
Currently, the market share of custom builds, based on a one-year moving average, is 20% of total single-family starts.
