The purpose of the medium and high-density residential zones is to promote a mix of housing opportunities combined with some limited commercial opportunities. It is the intent of the medium and high-density housing zones to be located in walkable and transit-oriented areas that allow for a wide range of amenities and businesses in close proximity.

To anticipate and respond to the changing needs of the municipality and implement housing choice and walkability concepts included in the adopted General Plan, including the vision of the Moderate Income Housing Opportunities Character Area, Kearns establishes the following zones:

1. Two-Family Residential Zones (R-2): The R-2 Zones are intended to promote medium-density middle housing options between one and two (1-2) units per building.
2. Four-Family Residential Zones (R-4): The R-4 Zones are intended to promote medium-density middle housing options between one and four (1-4) units per building. Multiple buildings may be located on one lot; however, lots with multiple buildings are encouraged to establish a PUD as part of the development process. Medium-density housing will serve as a transition between higher-density commercial, residential, or mixed-used and low-density residential or single-family.
3. Multi-Family Residential Zone (RM): The RM Zone is intended to promote medium and high-density residential housing of greater than four (4) units. Development projects in this zone should accommodate multi-modal transportation opportunities, open space, amenities for units, limited commercial uses, and provide buffering between high-density and low-density housing.

1. Schedule of Permitted Uses. The specific uses listed in the following schedule are permitted in the zones as indicated, subject to the general provisions, special conditions, additional restrictions, and exceptions set forth in this Title.
2. Procedure for Multiple Uses (Combination of Uses). If a development proposal involves a combination of uses other than accessory uses as identified in Table 19.30.030, the more restrictive provisions of this Title shall apply. For example, if a portion of a development is subject to conditional use (“C”) approval and the other portion is subject only to permitted use (“P”) review, the entire development shall be reviewed and approved by the conditional use process.
3. Abbreviations. The abbreviations used in the schedule mean:
   1. P = Permitted Use. This use is allowed in the zone but may be subject to additional restrictions and approval processes as provided in this Title.
   2. C = Conditional Use. This use is conditional because of the unique characteristics or potential impacts on the municipality, surrounding neighbors, or adjacent uses, incompatibility in some areas of the zone, or compatibility only if special provisions or conditions are required to mitigate the detrimental impacts of the use. The Planning Commission is the land use authority for uses with this designation.
   3. X = Prohibited Use. This use is prohibited in this zone. Any use not specifically identified in Table 19.30.030 is prohibited in this zone.

4. Restaurants, Retail and Service Commercial, and Retail Shops or Galleries where Primary Product is Produced On-Site: these uses are allowed with limitation in the RM Zone as follows:
   1. Such uses are only permitted within two-hundred and fifty feet (250’) of a fixed-route bus stop.
   2. The gross floor area of any building or portion thereof that contains a Restaurant, Retail and Service, or Retail Shop and Gallery use may not exceed five thousand square feet (5,000 sq. ft.).

Development in the R-2, R-4, and RM Zones shall comply with the development standards of Table 19.30.050 and all other applicable standards in this Title.

1. Density for Planned Unit Developments. The allowable density for planned unit developments is determined by the Planning Commission on a case-by-case basis, taking into account the following factors: recommendations of the Planning and Development Services staff and reviewing agencies; site constraints; compatibility with nearby land uses; and the provisions of the adopted General Plan. Notwithstanding the above, the Planning Commission may not approve a PUD with density higher than that which is enumerated in Table 19.30.040.
2. Calculating Density. Density calculations are based on gross density. Gross density is defined as the total number of residential dwelling units divided by the gross area of the parcel in question.

Development in the R-2, R-4, and RM Zones that is not part of an approved PUD shall comply with the yard, setback, and bulk standards shown in Table 19.30.050 and all other applicable standards in this Title.

1. There is no minimum side yard requirement where property lines are drawn along a shared wall.
2. Distance between Primary Buildings.
   1. Where dwelling units share a common wall, no setback is required.
   2. On lots with more than one primary building, the minimum distance between primary buildings is subject to Table 19.30.050B. It is intended that if lots with more than one primary building are ever subdivided, each building shall have a side yard equal to or greater than half of the required distance between buildings or the current standard for side yards as specified in the underlying zone. In the event that regulations conflict for side yards, the stricter requirement shall take precedence.

1. Buildings in the R-2, R-4, and RM Zones shall comply with the height standards of Table 19.30.050 and all other applicable standards in this Title.
2. No dwelling shall contain less than one story.
3. Within one hundred feet (100’) of sites zoned for single-family residential, the following standards apply:
   1. On the portion of the site within one hundred feet (100’) of a site zoned R-1, no structure or portion thereof may exceed thirty-five feet (35’) in height.  
   2. On the portion of the site within one hundred feet (100’) of a site zoned R-2, R-4, RM, or RMH no structure or portion thereof may exceed forty-five feet (45’) in height.

For each one foot (1’) of height over fourteen feet (14’), accessory structures shall be set back from property lines an additional one foot (1’) up to the allowed maximum height of twenty feet (20’).
3. No accessory structure or group of accessory structures shall cover more than twenty-five percent (25%) of the rear yard.
