Actually, I think it is better stated that building and zoning laws and the right to practice one's religion have competing interest. One doesn't override the other, unless the building/zoning code is expressly prohibiting something granted to someone by the US Constitution.

It could be, conceivably, legally permissible to say, "no mosques in X radius" if there were an overriding governmental interest to protect or assert.
