Officials tell KETK, the structure that caught fire was an unoccupied mobile home.
A man had burned brush over the weekend, and gusty winds stirred up hot embers that were left behind. The embers caught nearby grass on fire which jumped to the corner of the house.
Firefighters were able to contain the flames to one bedroom.
No one was injured in the fire.
Several fire departments are responding to a structure fire in the 18,000 block of County Road 223 in Arp.
Smith County officials say the blaze is under control.
KETK will bring you more information as it becomes available.
