In several towns I've lived in.. I _know_ everyone in city hall. It wouldn't be a deferential call, but a friendly one, where I'd mostly ask "Hey Bill, would there ever be a problem if I...."
Bill's got my back. If there was a problem, he'd be the first one to tell me _how_ to work around it, and since I'm the kind of guy to want to make things easy for everyone I live around, he'd probably be the first one to help do it if I needed it.
