It happened around 10:45 Saturday morning in the 9200 block of Landry Boulevard, according to HCSO.
According to Sheriff Ed Gonzalez, the child hit a residence, then backed into an unoccupied HCSO patrol vehicle before driving forward and crashing into a home.
HCSO said the child was an 11-year-old who is deaf and is autistic.
Officials said one of the homeowners was inside at the time, but fortunately was in another room. They said the boy's parents live just a few blocks away and arrived at the scene quickly.
"I do know that they’ve tried to keep the keys locked up and away from him they are not sure how he found these set of keys to the vehicle, but somehow he was able to get the key to the vehicle," said HCSO accident investigator Phillip Lillibridge.
Neighbors said they're thankful this turned out to just be an unfortunate accident instead of a deadly tragedy.
"Thank the Lord that nothing else happened other than just damage to the house. No one was in there in harm's way and, like I said, we're all blessed here," said one neighbor.
Authorities say the boy's parents are cooperating fully with investigators. It's unclear whether charges will be filed.
