You may sometimes also notice certain industrial spaces with exclusive parking lots which are considered as part of the total unit size or area. These may sometimes be good for certain companies or businesses as some companies may have many vehicles and may require exclusive parking lots directly in front of the unit for convenience or for easy loading and unloading due to frequent vehicle movement.
Hence, depending on your nature of business and company operations, common parking lots may or may not be a good thing. Various companies have various ways of operating and hence would have differing requirements in terms of industrial spaces.
