It all happened at a home off El Dora Road in San Juan just before 12 p.m. Thursday.
San Juan police told Action 4 News that they had received a tip about illegal activity at the home and under surveillance.
Authorities raided home and found 31 illegal immigrants from Honduras, El Salvador, Guatemala and Mexico inside.
Investigators said the immigrants had food and water but no heat or air conditioning.
A person believed to be the stash house caretaker is in custody and is expected to face criminal charges.
