Zones, R1, R2 And R3

17.40.010 Purpose

The purpose of the residential zone is to provide appropriate locations where residential neighborhoods may be established, maintained, and protected. The regulations also permit the establishment of, with proper controls, the public and semipublic uses such as churches, schools, libraries, parks and playgrounds, which serve the requirements of families. The regulations are intended to prohibit those uses that would be harmful to a single-family neighborhood.

"Institutional Care Center": An assisted living facility or any type, as defined by the Utah State Department of Health and Human Services, that is not a residential facility nor contained within a residential dwelling unit of a type authorized by the applicable zoning regulations.

"Intensity": The impact of a land use type on the land, e.g. apartment complexes are a high intensity land use while single-family residential is not.

"Overlay zoning district": A zoning district which is applied over one or more previously established zoning districts, establishing additional standards and criteria for covered properties in addition to those of the underlying zoning district; used to protect special features such as housing along transit corridors or historic buildings.

17.40.065 Fence Regulations A. Permit Required. Prior to erecting a fence, a permit must be obtained. Applications are available at the Manti City office or on the Manti City website. B. Side Yards and Rear Yards. In any required side or rear yard on lots, the total height of fences shall not exceed seven (7) feet, including base, unless otherwise allowed herein (See Figure #1) C. Front Yards. Fences in front yards shall be allowed provided that solid type fences shall not exceed three (3) feet, and open type fences shall not exceed four (4) feet. (See Figure #1). Fence Figure #1: Interior Lot Fence Height Restrictions




D. Corner Lots. In addition to the other provisions contained in this section, fences located on corner lots shall be subject to the following provisions (See Figures #2 & #4): 1. Any fence, wall, and/or hedge on the front yard setback, assuring there is a clear view zone, shall not exceed three (3) feet if solid construction or four (4) feet if open construction. 2. Height up to seven (7) feet shall be allowed adjacent to the side yard and rear yard street frontage area (the street-side area from the front line of the house to the back lot line), but not less than 35 feet from the front property line. To maintain a clear zone of visibility at street intersections, fence height within the thirty-five (35) foot area (measured from street improvements) shall conform to front yard fence requirements. See Figure #2 Fence Figure #2: Illustration of a Common 35-Foot Sight Visibility Triangle



3. When a driveway exists on an adjoining lot, a clear view zone shall be maintained free of fencing, except an open type fence or a view solid fence no higher than three (3) feet in height when a driveway exists on the adjacent lot within ten feet of the shared property line. The clear view zone refers to the portion of the corner lot lying within a triangular area formed by measuring back ten (10) feet from the point where the interior property line shared with the adjacent lot meets the property line along the public right-of-way (see figure #3).

Fence Figure #3: Clear View Zone



E. Heights on the rear yard setback and interior side yard setback shall not exceed seven (7) feet, unless otherwise allowed herein.

In new residential development that adjoins commercial/industrial zone, the placement of a fence is the responsibility of the commercial/industrial property owner. 6. Fence heights between commercial/industrial and residential zones shall be a minimum of seven (7) feet in height and shall be constructed of sight obscuring material. A fence exceeding seven (7) feet in height shall require a building permit. Fence Figure #4: Corner Lot Fence Height Restrictions
