How do communities that you are familiar with handle mobile businesses? Some like car washes, set up shop at the same location frequently and basically are establishing another use in the parking lot (these are the waterless car washes or self-contained units which wash cars using a tank and equipment on board the vehicle). These car wash operations are increasingly common. They want to set up in residential (apartment; condo) and commercial (office, mall) parking lots. If they set up frequently at the same location they are establishing a use there, no? Or are they viewed as "accessory" uses?
