Good on you for having him checked by the vet - that's definitely the first step that needs to be taken.
First, make sure you're cleaning the pee up really thoroughly. The cleaners specifically made for pet urine with enzymes to break down the smell are helpful. If he's smelling his past pees, it could encourage him to pee more. Is he crate trained? If he does not have a UTI or other medical issue causing this (and maybe even if he does, for the time being at least) I would crate him in a properly sized crate. I say properly sized because if it's too large he will likely pee in it anyways. It should discourage him peeing and might help him learn to hold it when no one is home. After a few weeks you could try leaving him out and see if he will hold it.
I have a small dog who, at 5 years old, needs to be monitored when it comes to his housebreaking. If I get too lax about potty breaks and such he will revert to peeing in the house and once he does it once he's way more likely to do it again. I go back to treating him like I'm housebreaking a puppy and he gets back on track after a week or so.
