American Homes / 1999–2025 · A Data Story
New Homes Are Getting Smaller Again.
The bigger-house trend wasn’t a straight line. New single-family homes shifted toward larger floor plans, then back toward smaller ones. Drag through the Census record to see where the change happened.

How New Homes Divide By Size

Floor Area · Square Feet
One step is one calendar year, from 1999 to 2025. The scale stays fixed.
Census survey estimate: ~1,005,000 homes completed. Published shares total 100%; rounding is retained.
These are size groups, not equal-width histogram bins. Bar height shows each group’s share, not homes per square foot. ~ marks survey estimates; published rounded percentages are not forced to sum to 100%.
02 / What Stands Out
Smaller Plans Have Regained Ground.
Homes under 1,800 square feet accounted for ~21% of completions in 2015 and ~32% in 2025. That is a change in what was built, not a measurement of what buyers wanted.
“Smaller Again” Doesn’t Mean Small.
In 1999, ~37% were under 1,800 square feet. The 2025 share was still below that level. Apartments, existing houses and manufactured homes are outside this chart.

Sources & Method
We use the United States section of SFTotalSqFt in the Census floor-area workbook, retaining all six published size groups for 1999–2025. This is the Survey of Construction’s estimate of new privately owned single-family houses completed, not houses sold or the entire housing stock.
Percentages come from the published percentage columns, which Census calculates from unrounded estimates. Counts are published in thousands; the table multiplies them by 1,000. Rounded counts and percentages can differ slightly from their totals. No residual is silently assigned to a size group.
The headline combines the two published groups below 1,800 square feet. We do not interpolate years or infer demand, affordability or household preferences from the size distribution. Estimates have sampling and nonsampling error; small year-to-year moves are not treated as statistically established changes.
