Property and buildings in the R1-Z District shall be subject to the following area regulations.
(A) Minimum lot size. The minimum lot size shall be 4,000 square feet. This shall not include any credit for streets, recreational area and common open space or water bodies.
(B) Dwelling unit setback. The minimum lot size shall be 4,000 square feet. This shall not include any credit for streets, recreational arm and common open space or water bodies.
(1) Interior side yard. The dwelling unit may be placed on one interior side property line with a zero feet setback and the dwelling unit setback on the other interior side property line shall be a minimum of ten feet, excluding the connecting elements such as fences, wall and trellises. Covered porches, covered patios and storage spaces which are connected to the principal structure may not encroach into this ten-foot side yard.
(2) Front setback. All habitable parts of a dwelling must be set back a minimum of 20 feet from the front property line, while garages may be set back a minimum of ten feet based upon the approval by the Planning Commission and its approval of the site plan. Garage setbacks of less than 20 feet must have an entrance parallel to the street or be approved by the Planning Commission as part of the site plan review process. An adequate driveway turning radius shall be provided for the structure.
(3) Rear setback. The dwelling setback shall be a minimum of 15 feet from the rear property line. When a garage is located in the rear of the property, the rear setback shall be a minimum of 20 feet.
(4) Side street setback. The side street setback shall be a minimum of 15 feet from the property line on the street side.
(C) Minimum lot width. The minimum lot width shall be 40 feet.
(D) Minimum lot coverage permitted. The total lot coverage permitted for all buildings on the site shall not exceed 60% of the lot area (140 x 40 = 5,600 = 3,360 square foot house). Temporary storage structures are not included in this coverage percent.
(E) Building height. No building shall exceed two stories and 35 feet in height. Upper story windows shall not face onto an adjacent property owner’s private space, or toward the zero lot line side.
(F) Street frontage. Each lot shall abut upon a clear, direct frontage of a dedicated city street. The zero lot line must abut upon the street line for a distance of not less than 30 feet.
(G) Platting requirements. Each dwelling shall be located on its own individual platted lot. If areas for common use of occupants of the development are shown on the plat, satisfactory arrangements shall be made for the maintenance of the common open space and facilities, in the form of a neighborhood association. The plat shall indicate the zero lot lines and easements appurtenant thereto.
(H) Openings prohibited on the zero lot line side. The wall of the dwelling located on the zero lot line side must be constructed of maintenance free, solid decorative masonry and have no openings.
(I) No portion of the dwelling or architectural features projects over any property line. The structure shall be offset in such a manner that eaves, overhangs or any architectural features shall not encroach on the adjoining. All yard areas on the zero lot line side, part of which may result due to the placement of the foundation off the property line shall be fenced by the property owner but shall be reserved for use by the adjoining property owner. Any adjoining property owner may fence in an area up to the zero lot line of the adjacent lot in order to contain the owner’s side yard.
(J) Maintenance easement. A perpetual five-foot maintenance easement shall be provided on the lot adjacent to the zero lot property line, which, with the exception of walls and/or fences, shall be kept clear of structures. This easement shall be shown on the plat and incorporated into each deed transferring title to the property. The wall shall be maintained in its original color and treatment unless otherwise agreed to in writing by the two affected lot owners. The roof shall be so designed that water runoff from the dwellings placed on the zero lot line drains onto the owner’s property.
(K) Utility easement. Due to the increased densities and compactness of zero lot line developments, the location of utilities constitutes special consideration. In order to ensure adequate access to maintain utilities, it is necessary to place utilities in the front yard easement, street or combination. However, a rear yard utility easement is allowed when a rear drive or rear open space easement is provided.
(L) Off-street parking. A minimum of two paved off-street parking spaces shall be provided on each platted zero lot line lot. Paved parking must consist of either concrete, asphalt or brick pavers.

(3) No accessory building or structure shall exceed ten feet in height without approval from the Zoning Board of Adjustment.
(N) Trees. There shall be a minimum requirement of one tree for each platted lot in order to enhance private space. In addition, street shade trees shall be provided along each side of the roadways at a minimum spacing of 40 feet in order to enhance the streetscape. This shall be in addition to the one tree required for each platted lot. Placement shall be determined by utility easement location.
(O) Fire protection. Walls on side yards shall have a minimum of one hour rated sheet rock installed and roofs shall be of flame resistant material and wooden, cedar shingle roofs are prohibited.
