Another thought...are you sure he goes when you let him out? My last sheltie a female was housebroken and reliable, but when she was young she started to pee in the kitchen when I was in the shower. I figured out it was because she was getting distracted outside and forgetting to do her business. I used to have to take her out on a leash to make sure she was doing what she was supposed to. I wish you good luck!
This is why I watch my dogs in the morning - because I want to KNOW they have gone, and not just fooled around out there sniffing after critters etc. I either go out with them or watch from the window.
