If you live in or have driven through Comal County, your eyes aren’t deceiving you. You’ve seen thousands of new residential rooftops pop up in the past decade.

In fact, Comal County ranks as No. 3 among primary U.S. metro counties with the most growth in new housing units (48.5 percent) from 2010 to 2020, according to U.S. Census Bureau data released November 2. Among those housing units are single-family homes, condos, townhomes, and apartments.

The number of housing units in Comal County rose by 22,831 from 2010 to 2020, the Census Bureau says.

Proving that everything is bigger in Texas, four other Lone Star counties make the top 10 on that list: 

  • First-ranked Hays County, part of the Austin metro area — 57.4 percent (34,117 new housing units).
  • Fifth-ranked Williamson County, part of the Austin metro area — 46 percent (74,907 new housing units).
  • Seventh-ranked Fort Bend County, part of the Houston metro area — 41 percent (80,880 new housing units).
  • 10th-ranked Rockwall County, part of the Dallas-Fort Worth metro area — 36.8 percent (10,280 new housing units).

The San Antonio metro area also claims one spot on the bureau’s list of the 10 “outlying” metro counties with the most growth in housing units from 2010 to 2020. The bureau defines outlying counties as those outside a region’s “urban center.”

Kendall County, ranked fifth on that list, saw the number of housing units go up by 30.4 percent from 2010 to 2020 with the addition of 4,275 units. 

Four other Texas counties appear on the same list for “outlying” counties:

  • No. 1 Denton County, part of the Dallas-Fort Worth metro area — 36 percent (92,136 new housing units).
  • No. 2 Montgomery County, part of the Houston metro area — 34.2 percent (60,842 new housing units).
  • No. 3 Kaufman County, part of the Dallas-Fort Worth metro area — 33.7 percent (12,906 new units).
  • No. 8 Bastrop County, part of the Austin metro area — 25.1 percent (7,367 new housing units).

“The number of occupied housing units grows when new housing is built or previously vacant homes become occupied. It decreases when housing units become vacant, are demolished or are converted into other uses,” the Census Bureau explains.
