Architectural features such as cornices, eaves, canopies, sunshades, gutters, signs, chimneys and flues shall not project more than eighteen (18) inches into a required yard.

If a lot or the aggregate of contiguous lots held in a single ownership as recorded in the office of the County Clerk at the time of passage of this code has an area or dimension which does not meet the lot size requirements of the zone in which the property is located, the holding(s) may be occupied by a use permitted in the zone, subject to the other requirements of the zone, provided that, if there is an area deficiency, residential use shall be limited to a single-family dwelling.

The following exceptions to the front yard requirement for any structure are authorized for a lot in any zone.

1. The required front or rear yard for a structure may be based on existing or probable average of the front or rear yards of dwellings/garages on all lots within one hundred (100) feet of both sides of the proposed structure. On vacant parcels within one hundred (100) feet, standard requirements shall be used in establishing the average.
2. Special set-back requirements. Under certain circumstances the following special set-back requirements shall apply:
   1. Buildings and pens, which are part of kennels and animal hospitals, and active recreation use areas which are a part of outdoor commercial amusement or recreation establishments shall be located no closer than seventy-five (75) feet from a residential zone.
   2. Clubs, lodges, fraternal organizations, community swimming pools, and buildings housing recreational facilities in residential zones shall be located no closer than thirty feet (30) from any other lot in a residential zone.

Projections such as chimneys, spires, domes, elevator shaft housings, aerials, flagpoles and other similar objects not used for human occupancy which exceed the maximum building height allowable in the zone by no more than five (5) feet are not subject to the building height limitations of this title. Such projections that exceed that height may be approved by the Planning Commission upon a finding that the structure will not result in an adverse impact to the neighboring properties.
