All roofs will have an eave (excluding gutters) extending a
minimum of 20 inches beyond the outside wall. An eave is that portion
of a roof projection beyond the wall which casts off water falling
on the roof. Eaves that are an extension of an existing eave will
match the existing eave. Eaves (excluding gutters) along the party
wall line will remain a minimum of 16 inches from the party wall line.
For room additions only, all eaves shall extend a minimum of 12 inches
and no more than 24 inches beyond the outside wall.
In addition to the relevant provisions in Chapter
21, the following regulations shall apply to the construction of all second floor additions:
(A) A second
story addition may extend from the original building's front wall
to the rear wall.
(B) The
second story addition should have a roof pitch of not less than a
three-inch rise for each twelve-inch horizontal measurement.
(C) The
second floor addition cannot cantilever beyond the front wall. The
existing eaves on the original first floor at the front wall, including
any gables that are extending with the existing eaves, must remain
as an architectural enhancement to help preserve the appearance of
the duplex neighbor. This requirement also applies to the U-shaped
original three-bedroom homes. The front wall for this type of duplex
shall be the courtyard wall and not the protruding third bedroom on
the front of the home.
(D) Architectural
drawings showing front elevations for review and approval by the Building
Department will be required without exception.
(E) With
L-shaped corner houses, the address will determine the front of the
house, not which way the front door faces. This allows a corner house
to cantilever or extend beyond the side wall facing the street. The
lot width will determine the distance it can extend on this side.
(F) All
second floor roof gutters must be pitched to drain to the front of
the house. Corner house second floor addition gutters can drain to
either the front or side of the house facing either street.
