[Amended during 2011 recodification. Code 1997 § 12-200-005.]

18.135.020 Amendments.

The zoning map and use restrictions may be amended by the city council from time to time, but any amendment shall be first submitted to the planning commission for its review and recommendation. No proposed amendment affecting the number, shape, boundary or zoning classification of any zone shall be adopted unless the proposed zoning ordinance amendment complies with the following criteria:

(1) The proposed amendment will place all property similarly situated into the same zoning classification or in complementary classification.

(2) That all uses permitted under the proposed zoning amendment are in the general public interest and not merely in the interest of an individual or small group.

(3) All uses permitted under the proposed zoning classifications amendment will be appropriate in the area to be included in the proposed zoning amendment.

(4) The character of the neighborhood will not be adversely affected by any use permitted in the proposed zoning classifications.

(5) The proposed zoning amendment is consistent with the city’s master plan.

Before adopting any amendment to this title the city council shall hold a public hearing. Notice of the time and place of the hearing shall be given by at least one publication in a newspaper of general circulation in the city, at least 14 days before the hearing. The cost of publication shall be paid by the applicant for the zoning change. Labels acquired through the Salt Lake County recorder’s office for the required notification to adjacent property owners shall be provided by the applicant, and the applicant shall take responsibility for providing accurate and complete mailing lists.

On any property requested for rezoning (except for rezoning initiated by the city to implement general planning objectives), the applicant shall be required to post the property in question with a notification of rezoning which states the zone classification being requested and the time and place of public hearing. The signs shall be obtained from the city and be posted at appropriate intervals around the property and on all corners at least 14 days prior to the public hearing. All adjacent property owners and all owners within 1,000 feet shall be notified 14 days prior to the date of the hearing. Mailed notification shall comply with requirements set forth by the city. Cost and responsibility of such posting and notification shall be borne by the applicant. [Ord. 16-10 § 1 (Exh. A). Code 1997 § 12-200-010.]

18.135.025 Reapplication following denial of rezone application.

Following denial of a rezone application by the city council, an identical application to rezone the use of the property, without regard to the applicant, will not be accepted for a period of one year from the date of denial. Zone changes initiated by the city are not subject to this regulation. Upon reapplication, the applicant for the same rezone request which was denied in a prior year shall be required to pay application fees as established by the city council. [Ord. 16-10 § 1 (Exh. A).]

18.135.030 Supplementary and qualifying regulations.

(1) Lots in Separate Ownership – Reduced Yards. The requirements of this title as to minimum lot area or lot width shall not prevent the use for a single-family dwelling on any lot or parcel of land in the event that the lot or parcel of land was held in separate ownership at the time such parcel became nonconforming as to area or width.

(2) Area of Lots Including a Public Right-of-Way. Lots created prior to the adoption of local zoning regulations, having a public right-of-way included in the parcel description, may include up to one-half of the right-of-way within the area calculations when so approved by the city council.

(3) Reduced Yards. On lots having a smaller width than required for the zone in which it is located, the width of each of the side yards for a dwelling may be reduced to a width not less than the same percentage of the width of the lot as the required side yard; provided, however, that on interior lots the smaller of the two yards shall be in no case less than five feet, or larger than eight feet, and for corner lots the street side yard shall be in no case less than 10 feet or the side yard be less than five feet.

(4) Yard Space for One Building Only. No required yard or other open space around an existing building shall be considered as providing a yard or open space for any other building, nor shall any yard or other required open space on an adjoining lot be considered as providing a yard or open space on a lot whereon a building is to be erected or established.

(5) Every Dwelling to Be on a Lot. Every dwelling shall be located and maintained on a lot as defined in this code.

(6) Sale or Lease of Required Space. No space needed to meet the width, yard, area coverage, parking or other requirements of this title for minimum lot or building requirements may be sold or leased away from such lot or building.

(7) Creation of Lots Below Minimum Space Requirements. No parcel of land which has less than the minimum width and area requirement for the zone in which it is located may be separated from a larger parcel of land for the purpose, whether immediate or future, of building or development as a lot.

(8) Yards to Be Unobstructed – Exceptions. Every part of a required yard shall be open to the sky (unobstructed), except for accessory buildings in a rear yard.
