Is one permitted to lease space for use as a Church or chapel?
The main issue is if they will be bringing in עבודה זרה. There was a time that they could not rent even an apartment to non-Jew because he would bring in his idols.
It’s not really relevant to areas where the non-Jews are not idol worshippers like Muslims & Christians. They don’t bring idols in and they don’t worship idols.
It’s a big debate over the generations. Landlords today usually lease to them without concern. You can do it if you like. Some believe you should do something like a heter iska, so you’re not directly leasing to them.
If you want to look it up inside, here’s a good place to start and then work your way back to the Gemara in Avoda Zara.
Thank you
