At what age was he neutered? If he was neutered late, he may have retained the inclination to mark, and simply didn't stop when the testosterone left.
If that isn't the case, then a vet visit is in order, just to rule out any medical problems.
Barring that, you need to go back to housetraining 101 - no freedom indoors when you are not there to supervise. NILIF can help. And, if there are other animals in the house, make sure he has a place to go where he isn't bothered. Keep all dogs off the furniture, and be sure to pat and praise all of them in each others' presence. (Dog learns...hmmm, when that other dog is around, good stuff happens to me).
