No use or occupancy of any building, structure
or land shall hereafter be changed to a different use or occupancy
and no building or structure or part thereof shall hereafter be erected,
constructed, reconstructed, moved or structurally altered unless in
conformity with all of the regulations herein specified for the district
in which it is located, except as hereinafter provided.
No building or other structure shall hereafter
be erected or altered to exceed the height, to accommodate or house
a greater number of families, to occupy a greater percentage of lot
area or to have a narrower or smaller rear yard, front yard, side
yard or other open spaces than are herein provided, or in any other
manner contrary to the provisions of this chapter, except as hereinafter
provided:
A. Corner lots. Building setback lines for a corner lot
shall be the same as required for front yards along both street rights-of-way.
B. Front yard requirement modifications.
(1) Where a lot has frontage upon a road proposed for
right-of-way widening, the required front yard depth shall be measured
from and parallel to the proposed right-of-way measured at right angles.
(2) Where a lot has frontage on any road with the street
line at less than 20 feet measured at right angles from the center
line, the required front yard depth shall be measured from a line
parallel to and at that distance from the center line.
C. Irregularly shaped lots. In the case of irregularly
shaped lots on cul-de-sac or curved street sections, the minimum lot
width specified in the schedule shall be measured at the building
setback, provided that in no case shall a distance between side lot
lines be reduced to less than 75% of the minimum lot width requirement
at the street line.
D. Overlapping required space. No part of a yard or other
open space or off-street parking or loading space required about or
in connection with any buildings for the purpose of complying with
this chapter shall be included as part of a yard, open space or off-street
parking or loading space similarly required for any other building.
E. Yard reduction. No yard or lot existing at the time
of passage of this chapter shall be reduced in size or area below
the minimum requirements set forth herein. Yards or lots created after
the effective date of this chapter shall meet at least the minimum
requirements as established by the chapter.
F. Uniformity. Within each district, the regulations
set by this chapter shall be minimum regulations and shall apply uniformly
to each class or kind of structure or land.
G. Public street frontage. Every principal building shall
be built upon a lot having sufficient frontage on a public street
or private right-of-way.

(1) The total horizontal area covered by such features
shall not exceed 20% of the area covered by the principal building.
Agriculture buildings shall not be subject to the horizontal area
limitation.
(2) The excess height of any structure shall not be greater
than the shortest distance from such structure to any required yard,
nor shall the total height exceed twice the building height limitation
in the district in which it is located.
I. Projections. Building projections, including bays,
chimneys, cornices and gutters, may extend into required yard areas
for a distance not to exceed five feet but shall not be located within
10 feet of any property line.
