My dog keeps peeing in my house

So I have a 2 dogs one is 3 yrs old and about 100 pounds and the other is 5 yrs old and about 56 pounds. Both dogs are penned during the work day as they have shown numerous times they cannot be left out alone during the day. We have always kept them out of their pens at night. My problem has been that my 5yr old will pee in the house throughout the night. We make sure to let them out before we go to bed and as soon as we wake up which is usually at about 5:30am. We have had this problem for quite some time as he pees on furniture and random spots throughout the house. Its almost never the same place 2 times in a row. Everything I've read has said to pen him at night but that starts a fight between me and my spouse as they believe thats not a good life. Its not that I dont agree with them its that I'm at my wits end with cleaning up pee almost every morning. Any suggestions on how to get him to stop peeing inside?
