Does he pee in the same place all the time? Have you tried putting kitten size litter boxes where he regularly pees?
Are there cats outside that may be un-neutered that he can smell?
Is he spraying your couches or squatting on them? I put a sheet over my couches when I wasn't home to prevent Jasper from spraying mine. It worked very well.
