Special purpose properties in Standard (IL) best serve tenants looking for facilities to fit their unique type of business or use. Since the Standard (IL) property has already been in use for its very specific use, there's no need to worry about Standard (IL) zoning laws or constructing a floor plan to fit one's needs. It's also well known to the public what type of Standard (IL) business is being practiced there, so public approval or awareness doesn't need to be marketed.
