1 These minimums per district apply if less than 50% of the lots on the blockface have been developed. If, however, 50% or more of the lots on the blockface have been developed, the applicable minimum, for all of these districts, is the lesser of (i) the average of the front-yard depths of the improved lots or (ii) 40 feet. 2 For semi-detached dwellings, interior-side yards are required only along the interior-side lot line where the party wall between dwellings is not located.
