The 2010 zoning code classifies the Montview corridor as an “urban single unit” (U-SU-H) district, with minimum lot sizes of 10,000 square feet; under the current arrangement, the Wongs would need to have a 20,000-square-foot lot in order to split it up, but their total lot size is 18,750 square feet. So the couple has applied for a zoning change that would essentially take the 50 x 125 strip behind the house out of the U-SU-H district and allow it to be developed as a Glencoe (rather than Montview) address — since, on the side street, the minimum lot size is only 5,500 square fee
