Subject to Subsection (B) and the provisions of Section 400.673 (Cluster Subdivisions) and Section 400.675 (Architecturally Integrated Subdivisions), every lot developed for residential purposes shall have the number of square feet per dwelling unit indicated in the following table. In determining the number of dwelling units permissible on a tract of land, fractions shall be rounded to the nearest whole number.

Two-family conversions and primary residences with an accessory apartment shall be allowed only on lots having at least one hundred fifty percent (150%) of the minimum square footage required for one (1) dwelling unit on a lot in such district. With respect to multi-family conversions into three (3) or four (4) dwelling units, the minimum lot size shall be two hundred percent (200%) and two hundred fifty percent (250%) respectively of the minimum required for one (1) dwelling unit.

No lot may be created that is so narrow or otherwise so irregularly shaped that it would be impracticable to construct on it a building that:

Without limiting the generality of the foregoing standard, the following table indicates minimum lot widths that are recommended and are deemed presumptively to satisfy the standard set forth in Subsection (A). The lot width shall be measured along a straight line connecting the points at which a line that demarcates the required setback from the street intersects with lot boundary lines at opposite sides of the lot.

No lot created after the effective date of this Chapter that is less than the recommended width shall be entitled to a variance from any building setback requirement.

Subject to Sections 400.667 and 400.675 and the other provisions of this Section, no portion of any building or any freestanding sign may be located on any lot closer to any lot line or to the street right-of-way line or centerline than is authorized in the table set forth in this Section.

Whenever a lot in a non-residential district has a common boundary line with a lot in a residential district and the property line setback requirement applicable to the residential lot is greater than that applicable to the non-residential lot, then the lot in the non-residential district shall be required to observe the property line setback requirement applicable to the adjoining residential lot.

Setback distances shall be measured from the property line or street right-of-way line to a point on the lot that is directly below the nearest extension of any part of the building that is substantially a part of the building itself and not a mere appendage to it (such as a flagpole, etc.).

Whenever a private road that serves more than three (3) lots or more than three (3) dwelling units or that serves any non-residential use tending to generate traffic equivalent to more than three (3) dwelling units is located along a lot boundary, then:

All accessory buildings in residential districts (i.e., those established by Section 400.370) must comply with the street right-of-way and side lot boundary setbacks set forth in Section 400.665 but (subject to the remaining provisions of this Subsection) shall be required to observe only a four (4) foot setback from rear lot boundary lines.

For purposes of this Section:

Subject to the remaining provisions of this Section, building height limitations in the various zoning districts shall be as follows:

Subject to Subsection (D), the following features are exempt from the district height limitations set forth in Subsection (B):

The features listed in Subsection (C) are exempt from the height limitations set forth in Subsection (B) if they conform to the following requirements:

Notwithstanding Subsection (B), in any zoning district the vertical distance from the ground to a point of access to a roof surface of any non-residential building or any multi-family residential building containing four (4) or more dwelling units may not exceed thirty-five (35) feet unless the Fire Chief certifies to the permit-issuing authority that such building is designed to provide adequate access for fire fighting personnel or the Building Inspector certifies that the building is otherwise designed or equipped to provide adequate protection against the dangers of fire.

Towers and antennas are allowed in all zoning districts to the extent authorized in the Table of Permissible Uses.

In any single-family residential subdivision in the zones indicated below, a developer may create lots that are smaller than those required by Section 400.650 if such developer complies with the provisions of this Section and if the lots so created are not smaller than the minimums set forth in the following table:

The intent of this Section is to authorize the developer to decrease lot sizes and leave the land "saved" by so doing as usable open space, thereby lowering development costs and increasing the amenity of the project without increasing the density beyond what would be permissible if the land were subdivided into the size of lots required by Section 400.650.

The amount of usable open space that must be set aside shall be determined by:

The provisions of this Section may only be used if the usable open space set aside in a subdivision comprises at least ten thousand (10,000) square feet of space that satisfies the definition of usable open space set forth in Section 400.705 and if such usable open space is otherwise in compliance with the provisions of Article XII.

The setback requirements of Sections 400.665 and 400.667 shall apply in cluster subdivisions.

In any architecturally integrated subdivision, the developer may create lots and construct buildings without regard to any minimum lot size, lot width or setback restrictions except that:

The number of dwelling units in an architecturally integrated subdivision may not exceed the maximum density authorized for the tract under Section 400.655.

To the extent reasonably practicable, in residential subdivisions the amount of land "saved" by creating lots that are smaller than the standards set forth in Section 400.650 shall be set aside as usable open space.

The purpose of this Section is to provide flexibility, consistent with the public health and safety and without increasing overall density, to the developer who subdivides property and constructs buildings on the lots created in accordance with a unified and coherent plan of development.

Subject to the other provisions of this Section, if:

If the proposed use of the remainder is a single-family detached residential subdivision, then the lots in such subdivision may be reduced in accordance with the provisions of Sections 400.673 and 400.675 except that the developer need not set aside usable open space to the extent that an equivalent amount of land has previously been dedicated to the City in accordance with Subsection (A).

If the proposed use of the remainder is a two-family or multi-family project, then the permissible density at which the remainder may be developed shall be calculated by regarding the dedicated portion of the original lot as if it were still part of the lot proposed for development.

If the portion of the tract that remains after dedication as provided in Subsection (A) is divided in such a way that the resultant parcels are intended for future subdivision or development, then each of the resultant parcels shall be entitled to its pro rata share of the "density bonus" provided for in Subsections (B) and (C).
