Of the 40 states and the District of Columbia where we are licensed, Utah has the largest share of homes built in 2020 or later: about 4.2 of every 100 housing units. Texas, at about 4.0, and Idaho, at about 3.9, are within their margins of error of Utah. Illinois and Connecticut have the smallest shares, about 0.7 each, within their margins of each other. The national figure is about 2.0. This study is written for real estate investors weighing business-purpose construction loans.
What the Census counts
The Census Bureau asks, at occupied and vacant housing units, when the building was first constructed. A remodel, an addition or a conversion does not change the answer. A unit still being built counts as vacant housing once its exterior windows, doors and final usable floors are in place. The figures cover units still standing at the time of the interview.
The Bureau warns that this question is more open to error than many others, because people may rely on memory or on estimates from longtime neighbors. The survey also pools interviews from 2020 through 2024, so a home finished in 2024 could not have been counted in the earlier years of that span. Read the first column as a way to compare states, not as a full count of everything built since 2020.
The table: 40 states and the District of Columbia
The second column counts homes built in 2020 or later out of every 100 housing units. The fourth adds homes built from 2010 to 2019. The margin of error is the Census Bureau’s, at 90 in 100 confidence, and applies to the column before it.

Source: U.S. Census Bureau, American Community Survey 5-year estimates, 2020-2024, table B25034, read from data.census.gov on November 5, 2026. Shares and margins worked out by Fidelity Residential.
How the figures were worked out
- Margins of error: from the Census Bureau’s formula for proportions. For the fourth column, the margin of the two groups added together is the square root of the sum of their squared margins.
- Counts are estimates too, each with its own margin, up to about 6,700 housing units for Texas.
What the table shows
- Above and below the nation. Seventeen of the 41 are above the national figure of about 2.0 by more than their margins of error and 22 are below it. Oregon and Oklahoma are within their margins.
- Built since 2010. Nationally, about 11.4 of every 100 homes were built in 2010 or later. Texas is highest at about 21.4, then Utah at about 20.5, apart by more than their margins. Connecticut has the smallest, about 5.2.
- Counts. Texas has the most homes built in 2020 or later, 480,590, then Florida with 328,925 and California with 195,611.
- New Jersey is 34th of the 41 at about 1.1, with 41,626 homes. That is below the national figure by more than the margins, and the place is not firm: Ohio and Hawaii are within their margins of it. Counting from 2010 it is 35th of the 41, at about 7.3, against the national 11.4; Massachusetts is within its margins of it.
If you want to read about construction loans
The table says nothing about any loan, and a count of new homes does not show who built them or how the work was paid for. A ground-up construction loan is a short-term loan for an investor who buys a lot and builds a new house, or builds on land they already own, to sell it or keep it as a rental. The money for the build is held back and released in draws as the work is finished and inspected. Loan programs differ from state to state, and the states in this table are where we are licensed, which says nothing about any one program. For the other end of the housing stock, see older homes by state.
Frequently asked questions
Why does the table show 40 states and the District of Columbia?
Fidelity Residential is licensed in 40 states and the District of Columbia, and the table covers those.
Does this count every home built since 2020?
No. It is a survey estimate from interviews spread over 2020 through 2024, each figure has a margin of error, and homes no longer standing at the interview are left out.
What is the difference between the two measures?
The first looks at homes built in 2020 or later. The second adds homes built from 2010 to 2019, so it covers a longer stretch of building.
