The share of smaller tons remained file excessive in 2024, with two out of three new single-family indifferent properties bought occupying tons beneath 9,000 sq. toes (1/5 of an acre or much less). Furthermore, a excessive share of 40% occupied tons beneath 7,000 sq. toes (or lower than 1/6 of an acre). These shares match the file highs established a yr earlier, in accordance with the newest Survey of Building (SOC). Evaluation of a quarter-century of SOC information reveals stark adjustments within the lot dimension distribution and paperwork a dramatic shift in direction of extra compact constructing during the last twenty years.
In 1999, when the Census Bureau began monitoring these sequence, lower than half (46%) of latest for-sale single-family indifferent properties occupied tons beneath 9,000 sq. toes. The share of those smaller tons fluctuated round 48%, by no means crossing the 50% mark, till 2011. A shift in speculatively constructed (or spec) dwelling constructing in direction of smaller tons first turned noticeable throughout the anemic housing restoration that adopted the Nice Recession. Over that interval, the share of spec properties constructed on tons smaller than or equal to one-fifth of an acre rose quickly, from 47% in 2010 to 61% proper earlier than the pandemic.

The development in direction of extra compact spec constructing continued throughout the post-pandemic housing increase, with the share of smaller tons gaining an extra 4 proportion factors over the last 5 years. The persistent shift in direction of constructing spec properties on smaller tons is seemingly tougher to elucidate in opposition to the backdrop of the pandemic-triggered suburban flight and presumed shifts in preferences in direction of extra spacious dwelling. Much less indicative of fixing client preferences or the residential enterprise cycle, the steadily rising share of spec properties constructed on smaller tons undoubtedly displays unprecedented lot shortages confronted by dwelling builders and their makes an attempt to make new properties extra reasonably priced.
A more in-depth have a look at the lot dimension distribution since 2010 reveals that essentially the most dramatic shifts occurred on the lowest finish, with tons smaller than 7,000 sq. toes (or beneath 1/6 of an acre) rising their share by 13 proportion factors. In 2010, 27% of all bought single-family indifferent properties occupied tons beneath 1/6 of an acre. The share was not a lot completely different from the 1999 recording of 28%. Quick ahead to 2024, and the proportion elevated to 40%. On the identical time, the share of single-family indifferent spec properties occupying tons between 1/6 and 1/5 acres elevated from 20% in 2010 to 25% in 2024.

On the different finish of the lot dimension distribution, the share of spec properties constructed on bigger tons exceeding half an acre shrank from 14% in 2010 to 9% in 2024. The share of properties occupying tons between 1 / 4 and half an acre declined from 24% to 19% over that interval. The market share of properties constructed on tons between 1/5 and 1/4 of an acre misplaced 8 proportion factors, declining from 15% to 7%.
The median lot dimension of a brand new single-family indifferent dwelling bought in 2024 is 8,506 sq. toes, or simply beneath one-fifth of an acre. That is barely bigger however statistically not completely different from the bottom on file median of 8,177 sq. toes set a yr earlier than the COVID-19 pandemic.

Whereas the nation’s manufacturing of spec properties shifts in direction of smaller tons, regional variations in lot sizes persist. single-family indifferent spec properties began in 2024, the median lot dimension in New England is 3 times bigger than the nationwide median.
New England is thought for strict native zoning rules that usually require very low density. Due to this fact, it’s not shocking that single-family indifferent spec properties began in New England are constructed on a number of the largest tons within the nation, with half of the tons exceeding 0.6 acres. The East South Central division is a distant second on the checklist, with the median lot occupying 0.3 acres.
On the different finish of the spectrum, the Pacific division, the place densities are excessive and developed land is scarce, has the smallest tons, with half of the tons being beneath 0.13 acres. The bordering Mountain division additionally studies typical tons smaller (0.15 acres) than the nationwide median.
Within the South, the West South Central division stands out for beginning half of single-family indifferent spec properties on tons beneath 0.15 acres. That is half the scale of typical tons within the neighboring East South Central division.

The evaluation above is proscribed to single-family indifferent speculatively constructed properties. Customized properties constructed on an proprietor’s land with both the proprietor or a builder performing as the final contractor don’t contain the work of knowledgeable land developer subdividing a property. Due to this fact, within the case of customized properties, tons consult with an proprietor’s land space reasonably than tons in a traditional sense. Nonetheless, the SOC studies lot sizes for customized properties and reveals that they have an inclination to have bigger tons. The median lot dimension for customized single-family indifferent properties began in 2024 is one acre.
For regional evaluation, the median lot dimension is chosen over the common since averages are usually closely influenced by excessive outliers. As well as, the Census Bureau usually masks excessive lot sizes and values on the general public use SOC dataset, making it troublesome to calculate averages exactly, however medians (because the midpoint of a frequency distribution) stay unaffected by these procedures.
