In this chapter and the associated zoning map, the SR-1 District is divided into two (2) subareas for the purpose of defining design criteria. In other portions of this text, the SR-1 and SR-1A are jointly referred to as the SR-1 District because all other standards in the zoning ordinance are the same.
A. Purpose Statement: The purpose of the SR-1 Special Development Pattern Residential District is to maintain the unique character of older predominantly single-family and two-family dwelling neighborhoods that display a variety of yards, lot sizes and bulk characteristics. Uses are intended to be compatible with the existing scale and intensity of the neighborhood. The standards for the district are intended to provide for safe and comfortable places to live and play, promote sustainable and compatible development patterns and to preserve the existing character of the neighborhood.
B. Uses: Uses in the SR-1 Special Development Pattern Residential District, as specified in section 21A.33.020, "Table Of Permitted And Conditional Uses For Residential Districts", of this title, are permitted subject to the general provisions set forth in section 21A.24.010 of this chapter and this section.
C. Minimum Lot Area And Lot Width: The minimum lot areas and lot widths required in this district are as follows:

D. Maximum Building Height: Maximum building height limits vary, depending upon the location. The following regulations apply for each area within the SR-1 district:
1. Pitched Roofs: The maximum height of buildings with pitched roofs shall be:
a. SR-1: Twenty eight feet (28') measured to the ridge of the roof, or the average height of other principal buildings on the block face.
b. SR-1A: Twenty three feet (23') measured to the ridge of the roof, or the average height of other principal buildings on the block face.
2. Flat Roofs: The maximum height of a flat roof building shall be:
a. SR-1: Twenty feet (20').
b. SR-1A: Sixteen feet (16').
3. Exterior Walls: Maximum exterior wall height adjacent to interior side yards:
a. SR-1: Twenty feet (20') for exterior walls placed at the building setback established by the minimum required yard.
b. SR-1A: Sixteen feet (16') for exterior walls placed at the building setback established by the minimum required yard.
c. In both the SR-1 and SR-1A districts, the exterior wall height may increase one foot (1') (or fraction thereof) in height for each foot (or fraction thereof) of increased setback beyond the minimum required interior side yard. If an exterior wall is approved with a reduced setback through a special exception, variance or other process, the maximum allowable exterior wall height decreases by one foot (1') (or fraction thereof) for each foot (or fraction thereof) that the wall is located closer to the property line than the required side yard setback.
(1) Cross Slopes: For lots with cross slopes where the topography slopes, the downhill exterior wall height may be increased by one-half foot (0.5') for each one foot (1') difference between the elevation of the average grades on the uphill and downhill faces of the building.
(2) Exceptions:
(A) Gable Walls: Walls at the end of a pitched roof may extend to a height necessary to support the roof structure except that the height of the top of the widest portion of the gable wall must conform to the maximum wall height limitation described in this section.
(B) Dormer Walls: Dormer walls are exempt from the maximum exterior wall height if:
(i) The width of a dormer is ten feet (10') or less; and
(ii) The total combined width of dormers is less than or equal to fifty percent (50%) of the length of the building facade facing the interior side yard; and
(iii) Dormers are spaced at least eighteen inches (18") apart.
4. Initial Construction: Building height for initial construction of a building shall be measured as the vertical distance between the top of the roof and the established grade at any given point of building coverage. Building height for any subsequent structural modification or addition to a building shall be measured from finished grade existing at the time a building permit is requested. Building height for the R-1 districts, R-2 district and SR districts is defined and illustrated in chapter 21A.62 of this title.
5. Stepped Buildings: Where buildings are stepped to accommodate the slope of terrain, each step shall have a horizontal dimension of at least twelve feet (12').
6. Additional Building Height: Additional Principal Building Height: Requests for additional building height for properties located in an H Historic Preservation Overlay District shall be reviewed by the historic landmark commission which may grant such requests subject to the provisions of section 21A.34.020 of this title.
E. Minimum Yard Requirements:
1. Front Yard:
a. SR-1: The minimum depth of the front yard for all principal buildings shall be equal to the average of the front yards of existing buildings within the block face. Where there are no existing buildings within the block face, the minimum depth shall be twenty feet (20'). Where the minimum front yard is specified in the recorded subdivision plat, the requirement specified on the plat shall prevail. For buildings legally existing on April 12, 1995, the required front yard shall be no greater than the established setback line of the existing building.
b. SR-1A: The minimum depth of the front yard for all principal buildings shall be equal to the average of the front yards of existing buildings within the block face. Where there are four (4) or more SR-1 principal buildings with front yards on a block face, the average shall be calculated excluding one property with the smallest front yard setback and excluding the one property with the largest front yard setback. Where there are no existing buildings within the block face, the minimum depth shall be twenty feet (20'). Where the minimum front yard depth is specified in the recorded subdivision plat, the requirement specified therein shall prevail. For buildings legally existing on April 12, 1995, the required front yard depth shall be no greater than the established setback line of the existing building.
2. Corner Side Yard:
a. SR-1: Ten feet (10'). For buildings legally existing on April 12, 1995, the required corner side yard shall be no greater than the established setback line of the existing building.
b. SR-1A: Ten feet (10').
3. Interior Side Yard:
a. Twin Home Dwellings: No side yard is required along one side lot line while a ten foot (10') yard is required on the other.
b. Other Uses:
(1) Corner lots: Four feet (4').
(2) Interior lots:
(A) SR-1: Four feet (4') on one side and ten feet (10') on the other.
(B) SR-1A: Four feet (4') on one side and ten feet (10') on the other.
(i) Where the width of a lot is forty seven feet (47') or narrower, the total minimum side yard setbacks shall be equal to thirty percent (30%) of the lot width with one side being four feet (4') and the other side being thirty percent (30%) of the lot width minus four feet (4') rounded to the nearest whole number.
(ii) Where a lot is twenty seven feet (27') or narrower, required side yard setbacks shall be a minimum of four feet (4') and four feet (4').
(iii) Where required side yard setbacks are less than four feet (4') and ten feet (10') an addition, remodel or new construction shall be no closer than ten feet (10') to a primary structure on an adjacent property. The ten foot (10') separation standard applies only to the interior side yard that has been reduced from the base standard of ten feet (10').
4. Rear Yard: Twenty five percent (25%) of the lot depth, but not less than fifteen feet (15') and need not exceed thirty feet (30').
5. Accessory Buildings And Structures In Yards: Accessory buildings and structures may be located in a required yard subject to section 21A.36.020, table 21A.36.020B, "Obstructions In Required Yards", and section 21A.40.050 of this title.
a. SR-1A:
(1) Maximum building coverage of all accessory buildings shall not exceed six hundred (600) square feet.
(2) Primary accessory building: One accessory building may have up to the following dimensions:

(B) Roof peak/ridge height of up to fourteen feet (14') above the existing grade.
(C) A flat roof height limit of nine feet (9') above the existing grade.
(D) An exterior wall height of nine feet (9') above the existing grade.
(i) Lots with cross slopes where the topography slopes, the downhill exterior wall height may increase by one-half foot (0.5') for each one foot (1') difference between the elevation of the average grades on the uphill and downhill faces of the building.
(3) Secondary accessory buildings: All other accessory buildings shall have the following dimensions:
(A) Roof peak/ridge height of up to ten feet (10') above the existing grade.
(B) Flat roof height limit of eight feet (8') above the existing grade.
(C) An exterior wall height of eight feet (8') above the existing grade.
(D) Secondary accessory buildings may be attached to the primary accessory buildings so long as all buildings conform to the required wall and roof ridge height restrictions.
F. Maximum Building Coverage: The surface coverage of all principal and accessory buildings shall not exceed forty percent (40%) of the lot area. For lots with buildings legally existing on April 12, 1995, the coverage of existing buildings shall be considered legal conforming.
G. Maximum Lot Size: With the exception of lots created by a subdivision or subdivision amendment recorded in the office of the Salt Lake County recorder, the maximum size of a new lot shall not exceed one hundred fifty percent (150%) of the minimum lot size allowed by the base zoning district. Lots in excess of the maximum lot size may be created through the subdivision process subject to the following standards:
1. The size of the new lot is compatible with other lots on the same block face;
2. The configuration of the lot is compatible with other lots on the same block face; and

H. Standards For Attached Garages:
1. Width Of An Attached Garage: The width of an attached garage facing the street may not exceed fifty percent (50%) of the width of the front facade of the house. The width of the garage is equal to the width of the garage door, or in the case of multiple garage doors, the sum of the widths of each garage door plus the width of any intervening wall elements between garage doors.
2. Located Behind Or In Line With The Front Line Of The Building: No attached garage shall be constructed forward of the "front line of the building" (as defined in section 21A.62.040 of this title), unless:
a. A new garage is constructed to replace an existing garage that is forward of the "front line of the building". In this case, the new garage shall be constructed in the same location with the same dimensions as the garage being replaced;
b. At least sixty percent (60%) of the existing garages on the block face are located forward of the "front line of the building"; or
c. The garage doors will face a corner side lot line. (Ord. 64-21, 2021: Ord. 59-16, 2016: Ord. 7-14, 2014: Ord. 66-13, 2013: Ord. 73-11, 2011: Ord. 12-11, 2011: Ord. 26-06 § 1, 2006: Ord. 90-05 § 2 (Exh. B), 2005: Ord. 88-95 § 1 (Exh. A), 1995: Ord. 26-95 § 2(12-7), 1995)
