Mishnayos Avodah Zarah Perek 4 Mishnah 3

In the case of an object of idol worship that had a garden or a bathhouse, one may derive benefit from them when it is not to the advantage of the idol worship, i.e., when he does not pay for his use, but one may not derive benefit from them when it is to their advantage, i.e., if one is required to pay for his use. If the garden or bathhouse belonged jointly to the place of idol worship and to others, one may derive benefit from them, both when it is to their advantage and when it is not to their advantage.
