Andrea Calevo, 30, and his mother were at the home in La Spezia, a coastal city in northern Italy Sunday when three or four armed, masked men burst in. ANSA news agency said the men stole 3,000 euros from a safe and took Calevo. His mother was able to escape and called police.
The car the kidnappers used was found pushed into a lake not far from the home.
Police said it's possible Calevo's kidnapping wasn't initially intended, but improvised by the burglars targeting his home.
Calevo runs a company making prefabricated construction materials, which was founded by his grandfather, ANSA said.
