Where dwellings exist on adjacent nonconforming lots which have front, side or rear yards less than the minimum depth required by this chapter, the minimum yards required for construction of a dwelling on an adjacent undeveloped nonconforming lot shall be the average of the front, side or rear yards of the immediately adjacent developed lots on either side of the undeveloped lot, provided that in no instance shall a front or rear yard be less than five feet, and a side yard shall not be less than 2 1/2 feet.
6. 
Projections into required front and rear yards. All structures, whether open or enclosed, including porches, balconies or other platforms above normal grade level, shall not project into any minimum front, side or rear yard with the following exceptions:

Balconies or other aboveground platforms, open fire escapes and access steps to a structure, not exceeding six feet in width, may extend up to three feet into a required front or rear yard.
C. 
An unenclosed porch for a residential structure may extend into a required side yard, provided that the porch is not more than 10 feet in height and is no closer than 2 1/2 feet to any side lot line or 10 feet to any rear lot line.
7. 
Access to public street. All lots shall have access either directly or via a driveway to a public street. Such driveway shall have a uniform width of not less than 12 feet.
8. 
Height exceptions. Church spires and towers, chimneys, elevator bulkheads and other mechanical equipment which is part of the principal structure, standpipes, elevated water tanks, flagpoles, silos, conveyors and similar structures which are not intended for human habitation and which are not conditional uses regulated by Part 11 may exceed the height limitations of the zoning district in which they are located by not more than 15 feet.
