How large is the condo complex? I'm wondering if you can ask someone who has lived there longer, how these things are usually handled.

It seems to me that just as a matter of respect, NO ONE walks close to the building, with folks living on those levels. Only the folks who live on that level walk right up close to the building. Do any of the folks on the ground floor have flowers they have set out in pots, or anything which sort of designates the area as "theirs?"
