Proposed change could mean more guest houses in Bexar County

SAN ANTONIO – Prefabricated modular homes may soon be on the rise in San Antonio thanks in part to a proposed change to the city’s development code.

Last month, the Business Journal wrote about a proposed amendment to the development code going before city council in October, which reduces restrictions for homeowners to build guest homes.

While the change wouldn’t be bound to prefabricated construction methods, the style lends itself to guest home construction. Factory-built construction, which can include building individual panels to be assembled on-site, or fully completing construction on a building and shipping it to a location, has advantages.

One Houston subcontractor, which just set up shop in the Alamo City and specializes in prefabricated modules, told the Business Journal that it put the need for skilled labor on the design end rather than the construction end of development, indicating that their modules could be built in weeks and assembled in days by a fraction of the number of workers traditional construction methods need.

Accessory dwelling units, or ADUs, are secondary homes on a property which could be separate guest houses, or garage or basement dwellings attached to the primary home on the property.

“We’re very interested in the ADU amendment going through the city right now,” said Braustin Homes CEO Alberto Piña.

San Antonio-based Braustin, a prefabricated mobile home dealer, recently hired a chief financial officer and two executives to help scale up its business and keep up with a steady increase in demand since it opened in 2017.

“This industry does well when traditional housing costs become too expensive, when borrowing costs go up or when material costs have gone up,” Piña said. “Right now it’s kind of a perfect storm of all of those conditions.”

The sentiment is also shared by Bob’s Containers founder Robert Balderas, who has also been keeping an eye on the amendment from the outside. Based in Austin, Bob’s Containers manufactures containers homes and is poised to bring his game to town if the amendment goes through – and if some factors hold.

Some San Antonio residents have raised concerns during public meetings about an amendment making it easier to build ADUs, noting they could be used as short-term rental properties on platforms like Airbnb and Vrbo.

“My main concern is my kids,” one resident said during a July 5 zoning commission meeting. “With these renters, there are no background checks and the ‘hosts’ don’t ever interact with them except online.”

So far, Balderas said that isn’t the case for his company locally.

“In Austin, people use our products mostly as Airbnbs,” he said. “But in San Antonio, we see them used mostly as guest houses.”

The Business Journal will continue to follow the story and provide an update after the full City Council votes on the proposed amendment in October.
