If, at the time of passage of this chapter, a lot or the aggregate
of contiguous lots of land parcels held in a single ownership has
an area of dimension less than required for the zoning district in
which the property is located, the lot or aggregate holdings may be
occupied by any permitted use in the district, subject to compliance
with all other requirements of the district; provided, however, that
the use of a lot in any residential district which has an area deficiency
shall be limited to a single-family dwelling.
If there are dwellings on both abutting lots with front yards
of less than the required depth for the district, the front yard for
the lot need not exceed the average front yard of the abutting dwellings.
If there is a dwelling on one abutting lot with a front yard of less
than the required depth for the district, the front yard need not
exceed a depth 1/2 way between the depth of the abutting lot and the
required front yard depth.
Projections such as chimneys, spires, domes, elevator shaft
housings, aerials, other than freestanding, flagpoles and other similar
objects not used for human occupancy are not subject to the building
height limitations of this chapter; except, however, if the provisions
or requirements of the Airport Overlay District apply, the exceptions
granted in this section no longer are in force.
