I am working on area plan that contains several single family homes that front on a new multilane portion of highway. it is across the street from an auto dealership and a few of the homes are zoned for commercial use now; however not used for that purpose. I am looking for design guides/tips that could serve as a guide to property owners that wish to convert there homes to commercial establishments. I think it should address signage, parking, lighting and so-on.
Got any ideas, links, comments... ?
