How did UCD come up with the figure of “four or more” units?
UCD used commonly accepted levels of inclusion for Business Improvement Districts and checked it against the University City housing stock. Commerical properties and apartment buildings require a greater level of service and benefit more from those services than do single family residences. The Steering Committee agreed it would be unfair to burden single family homeowners; those who can afford to pay for the benefits are encouraged to do so by donating. This Business Improvement District is is a collaboration of businesses and landlords, and renting more than four units is a fair definition of a landlord.
