The fire on June 11 killed a 72 year-old woman. Tenants in the nine story building had to be evacuated. Most stayed with family and friends, 30 had to relay on the Arkansas Chapter of the American Red Cross which put them up in a local church.
Tariq Ferguson was moving his family back into their apartment.
"I have deep concerns...not knowing the cause of the fire is deeply alarming," he said, adding he would rather live in a house.
Investigators are still trying to determine the cause of the fire which firefighters contained to one unit.
