(C) All accessory buildings, uses, and structures shall comply with the side and rear yard setback requirements for that district. Accessory structures shall only be located in the side or rear yard, except garages, carports, fencing, mailboxes, and structures customarily associated with being the front yard may be located in the front yard.
(D) Except as provided elsewhere in this code, no accessory structure shall be constructed and used as a dwelling; provided, however, that one residential unit for a caretaker may be permitted in conjunction with any active industrial establishment.
(Ord. passed 6-3-2019)
§ 157.117 YARD/SETBACK REQUIREMENTS.
(A) All yards required to be provided under this code shall be open to the sky and unobstructed by any building or structure, except for accessory buildings or structures in the side or rear yard and within the building setback line, fences, and the following which may project into the required yards as established in this code:
(1) Steps and stoops not exceeding 24 square feet;
(2) Open or lattice-enclosed fire escapes, fireproof outside stairways and balconies opening upon fire towers, and the ordinary projection of chimneys and flues into the rear or side yard not exceeding three and one-half feet in width and placed so as not to obstruct light or ventilation; and

(Ord. passed 6-3-2019)
§ 157.119 ADDITIONAL PRINCIPAL BUILDINGS.
(A) Dwellings. Individual lots or subdivided parcels ten acres or less in size shall have no building or buildings used for living purposes in addition to the principal building on the same lot, except garage apartments where permitted in a zoning district. Undivided land parcels of ten acres or greater in size shall be limited to one residential structure per ten acre unit of undivided land area. This provision does not apply to factory-built home rental communities.
(B) Non-dwellings. Where a lot is not used as a dwelling, more than one principal building may be located upon the lot or tract, but only when such buildings conform to all open space and yard requirements around the lot for the district in which the lot or tract is located. A lot is not used as a dwelling for purposes of this section when the lot contains a caretaker’s residence used in conjunction with an active industrial establishment or a place of worship or religious institution as provided in this code.
(Ord. passed 6-3-2019)
§ 157.120 ORIENTATION OF PRINCIPAL STRUCTURES.
All principal structures shall be required to have a front door facing the street unless the Zoning Officer determines that the prevailing condition of the developed lots fronting the same street would warrant a different orientation, or another orientation is necessary for emergency services access.

Subject to the following conditions, fences and walls may be erected and hedges and other plantings may be grown along the boundaries of a lot.
(A) Clear sight triangle. Fences, hedges, other plantings, or walls at street corners shall not interfere with any clear sight triangle. The height of such objects is restricted to three and one-half feet within the clear sight triangle. No fence, hedge, other plantings, or walls shall otherwise impose a threat to the public safety, including by obstructing the view of motorists to oncoming traffic or pedestrians.
(B) Height restrictions. Fences, walls, hedges, and other plantings used for the purpose of screening shall not exceed 42 inches in height from the front building line extending to the front lot line, and shall not exceed six feet in height extending behind the front building line of the main structure, excluding porches and stairs.

(4) The finished side of the fence shall be oriented toward the front of the lot or the direction of the adjacent property owner, unless the fence is not visible from adjoining property.
(D) Landscaped buffer areas.
(1) Five foot landscaped buffer areas are the preferred method of buffering. However, where a buffer strip is considered to be impracticable or inappropriate, an opaque fence at least six feet in height, in the rear or side yard, or four feet in height in the front yard so as to restrict a clear view beyond said buffer may be substituted in whole or in part for a natural buffer, subject to approval by the Zoning Officer.
(2) Landscaped buffer areas shall be continually maintained by the landowner. Any plant material that does not survive shall be replaced within six months. All landscaping shall be kept free of refuse and debris.
(3) Landscaped buffer areas may be required by the Board of Zoning Appeals as a condition of a conditional use permit.
(4) Landscaped buffer areas shall not be required where the lot abuts an area of existing natural vegetation that effectively screens the lot from casual observation to a height of at least eight feet
(5) All species within the screen planting shall be indigenous or otherwise well-suited to the city, except that trees with large leaves which could clog storm drains; trees that are brittle, disease- prone, have low, spreading branches or shallow root systems; trees that drop large fruit or much sap; or any plantings that are otherwise messy shall also be avoided.
(6) Hedges shall be kept trimmed so that their branches shall not extend into the public road, or upon the lands of an adjoining owner, more than 18 inches over the dividing line.
(E) Location of buffer areas. Landscaped buffer areas shall be provided between any new multi- family, commercial, or industrial development that is adjacent to single-family residential property (existing or zoned) or adjacent to any dwelling, which landscaping shall be at least five feet wide and at least five feet high, subject to height limitations contained within this section.
(F) Tree placement. At least one tree for each 50 linear feet shall be planted in a landscaping strip in addition to other planting materials.
(G) Barriers. Landscaped areas shall be protected from the encroachment of vehicles by use of curbing, wheel stops, bollards, fencing, or other approved barriers.

(Ord. passed 6-3-2019)
§ 157.123 LOT LINES AND IRREGULAR LOTS.
(A) Corner lots. Corner lots shall have no rear lot line.
(B) Flag lots. When the handle of a flag lot is less than the minimum width for a lot in the zoning district in which it is located, the handle is not to be used in delineating the minimum required lot width. The minimum lot width shall be taken from the front building setback line; however, the handle shall be used in computing the required minimum lot size, except that in no case shall the area of the handle constitute more than 50% of the entire lot. Additionally, no structures, whether primary or accessory, shall be placed in the handle.
(C) Lot width. In a case where there is only one side lot line, lot width shall be measured between such side lot line and the opposite rear lot lines or street line.
(D) Irregular lots. Front setbacks for irregular lots shall be measured from the front lot line adjacent to the street right-of-way with the greatest frontage in linear feet.
(E) Pie-shaped lots. Setbacks on pie-shaped lots shall be measured at the closest point between the building and the angled lot line.
(F) Rear lot line (irregular). In the case of a lot having no street frontage or a lot of an odd shape, only the one lot line farthest from any street shall be considered a rear lot line. Where there is only one lot line other than street lot lines, it shall be considered the rear lot line.
