Frustrated with cat

I know I know, not baby related. 
I have a two year old male cat that I rescued when he was a baby, he's always been skiddish but very sweet. I got him fixed a little over a week ago and in the past three days he has peed on my BRAND NEW couch TWICE. (We've only had the couch 4 days) My husband is to the point of getting rid of him, our last place we lived (with two other cats) smelt absolutely horrid and he doesn't want to go through that again. I on the other hand, don't want to get rid of him. At the same time, I can't have him peeing all over our furniture.  Especially since I'll be bringing in more furniture in the next few weeks to prepare for the new baby. Does anyone have any suggestions? 😕
