2 that no building or structure may sit within a minimum required yard except as the Schedule of Dimensional Regulations allows, and that any structure more than eight inches above finished grade, other than fences and walls, must meet the accessory-building setback. 1 then lists specific encroachments permitted into required yards in R1 Residence Districts, the RO District and the HD-III Subdistrict: roof overhangs and canopies up to six feet into a front or rear yard; air conditioning units, window sills and similar minor features up to four feet into a side yard or six feet into a front or rear yard, but never closer than three feet to any property line; handicap ramps up to five feet into a side yard or 10 feet into a front or rear yard, again no closer than three feet to the line; propane tanks up to eight feet into a side or rear yard, no closer than eight feet to the line; and generators up to eight feet into a side or rear yard, no closer than eight feet to the line.

3 gives corner lots held in single ownership since January 27, 1953 a reduced front-yard depth, up to 50% less but never under 20 feet, along the frontage the house does not face, keyed to lot width thresholds of 200 feet in the R1-2A District, 125 feet in R1-1A, 100 feet in R1-20 and 60 feet in R1-6. 5 feet from obstructing sight lines in the triangle formed by street right-of-way lines 30 feet from a corner lot's intersection point. 3 lets the Department of Planning and Development apply the average or predominant existing front-yard setback pattern of an established neighborhood instead of the district minimum, for both new and expanded construction, though it can never force a deeper setback than the district's own maximum front-yard requirement.
