[TheThinkTank] Bicycle Co-Ops & Zoning?

Hello, I operate a small bike Co-op in a small, run down town called Beaver Falls, PA. We're looking into purchasing a location and think we've found the perfect spot. It's a former business / house with a three car garage and a large glass storefront area. The only problem is that it's zoned residential even though it used to be a business many years ago. The street is pretty run down, with three of the four 'neighbors' being vacant housing, so I'm not too worried about neighbors complaining about it. I'd like to paint our logo on the garage but I'm afraid that it my draw too much attention from the zoning people. Do any of your co-ops operate in non-commercialy zoned space? Have you had any problems arise because of it? Thanks, Jake
