Adding Spouse to Rover Account?

I might be out of town for the remainder of the summer and we have a client who's dog stayed at our house and wants to book us again. When I first made the account I was doing it on my own and my husband is physically there, but not on my account. I have seen some accounts where it is a couple or a family, is there any specific thing I need to do to get him added to my account? I assume Rover would want to run a background check on him. He was so excited to hear this dog wants to stay with us again, especially since I will be away, that he offered to watch it himself. Your help and advice is appreciated!
