Thank you for your question.
I can understand wanting to mount something to the side of the house with a stucco finish, like bird feeders or a mail box or flower box.
Because you are renting, I would suggest you find an alternative way to mount what ever you want to do, just not on the stucco.
I do not recommend mounting anything to stucco. I had a house with English ivy crawling up the stucco and while it was pretty, I had to pull it all down because it was holding moisture and causing the stucco to crack.
