when I was a kid we lived way up in the woods and had bears in the yard 2-3 times a month. My mom got one of those portable airhorn things and that would chase it away.
The bear isn't really a threat to you. If it wanted a piece of you it would have already tried to take it. Just make some noise or put up an electric fence and he will move on. like others said, don't be surprised if you put in a pool and come home to find him in it from time to time. But a little noise and it should get out of there and move on to a more quiet neighbor
also, like eveyone said watch your dogs. We had two dogs that were big ( a husky and a great dane ) and the bears never messed with them but a guy that lived down the street had a little pug that just disappeared one day. probably bear food.
good luck and enjoy your new friend.
