Claiming 42 year old son who lives in a house I own in the same town

My wife (we fill jointly) owns a house in town that has been occupied by my son for a few years. He is not going anywhere. I pay all the expenses for the house, taxes, insurance, electric, fuel, internet and repairs. I even pay his credit card to avoid ridiculous interest rates. 

He does not work. Can I claim him as living in our house for the full year?
