BATON ROUGE, La. (BRPROUD) — Louisiana attorney Lance Unglesby has filed a class-action lawsuit against homebuilding company D.R. Horton.

The lawsuit claims at least 50 D.R. Horton homes are not equipped for the state’s humidity and high temperatures. The lawsuit says residents experience mold and mildew, cooling issues, among a long list of other issues.

“I am under the impression they are the largest homebuilder in the United States,” said Unglesby.

They say the poor ventilation resulted in excessive moisture and mold. Unglesby says humidity levels in homes are double what they should be. He says some homes’ vents are the wrong size and the sockets are closed off.

“I had a client last night send me an email. She’s been having problems for 10 years,” he said.

Unglesby says homeowners have called D.R Horton to fix the problem but never get a permanent fix.

“D.R Horton builds these homes too fast and they don’t know how to build them properly. And as a result of that these subcontractors are making mistakes,” said Unglesby.

D.R. Horton representatives say they cannot comment on pending litigation. They say, “D.R. Horton home foundations and structures are designed by professional engineers based on site-specific conditions.”

D.R. Horton provided the following:

  • Building materials are selected based on performance and sustainability.
  • Air conditioning systems are designed for each home in accordance with ASHRAE standards and local building codes. 
  • In addition to local municipal inspections, we employ third-party inspectors throughout the building process to supplement quality control.
  • Every D.R. Horton home comes with a robust warranty that exceeds the duration required by the Louisiana New Home Warranty Act. 

“We always encourage any homeowner with concerns about their home to contact us at or by submitting a warranty request at”

D.R Horton is asking to solve the issue through arbitration. But a hearing is scheduled for Aug. 1.

“You end up with a bunch of homeowners with a home that they didn’t bargain for. D.R Horton is spinning these people around, they are not accommodating for the mistakes they made,” said Unglesby.
