In my community churches are conditional uses in the zones in which they are allowed. There are good reasons for that relating to traffic, noise, ancillary uses, etc. But we have run into situations in which a start-up group is renting an existing storefront in a strip mall for their "church." I am reluctant to put them through the whole CUP process for a small building that already exists. But I seem to have no choice. Do other communities distinguish between churches in new buildings and churches in existing buildings? Or have different rules for different sizes of buildings or congregations?
