14-4C-2: SPECIFIC APPROVAL CRITERIA:
Any accessory uses listed in the following subsections must comply with the conditions listed, unless specifically exempted or superseded by more specific provisions of this title. As noted, some require special exception approval from the Board of Adjustment. If a regulation in the base zone chapter conflicts with a regulation contained in this article, the regulation that is more specific to the situation applies. When regulations are equally specific or when it is unclear which regulation to apply, the more restrictive regulation will govern.
   A.   Accessory Dwelling Units (ADUs): ADUs are permitted provided the following conditions are met:
      1.   Applicability: The ADU shall be located in a zone that allows household living uses and shall be accessory to a principal use that consists of no more than two (2) dwelling units on a lot.
      2.   Ownership:
         a.   The owner of the property on which an ADU is located must occupy at least one of the dwelling units on the premises as the permanent legal resident.
         b.   The ADU and the principal use must be under the same ownership.
      3.   Site Requirements:
         a.   Only one ADU may be established per lot.
         b.   The minimum lot size and area per unit requirements of the underlying base zone must be met, but no additional lot area is required beyond that which is required for the principal use.
      4.   Design Requirements:
         a.   The ADU must be a complete, separate dwelling unit that functions independently from the principal use. It must contain its own kitchen and bathroom facilities, in addition to a separate entrance from the exterior.
         b.   When located within a building with an existing principal use, the ADU must be designed so that the appearance of the building remains that of an allowed use within that zone, and any new entrances, exterior finish materials, trim, windows, and eaves must visually match the principal use.
      5.   Apartment Size: The floor area of the ADU may not exceed fifty percent (50%) of the total floor area of the principal use, excluding the area of an attached garage, or one thousand (1,000) square feet, whichever is less.

      3.   Special Exception Approval Criteria:
         a.   Access And Circulation: The transportation system should be capable of safely supporting the proposed drive-through use in addition to the existing uses in the area. Evaluation factors include street capacity and level of service, effects on traffic circulation, access requirements, separation of curb cuts, and pedestrian safety in addition to the following criteria:
            (1)   Wherever possible and practical, drive-through lanes shall be accessed from secondary streets, alleys, or shared cross access drives. If the applicant can demonstrate that access from a secondary street, alley, or shared cross access drive is not possible, the board may grant access to a primary street, but may impose conditions such as limiting the width of the curb cut and drive, limiting the number of lanes, requiring the drive-through bays and stacking lanes to be enclosed within the building envelope, and similar conditions.
            (2)   To provide for safe pedestrian movement, the number and width of curb cuts serving the use may be limited. A proposal for a new curb cut on any street is subject to the standards and restrictions in chapter 5, article C, "Access Management Standards", of this title.
            (3)   An adequate number of stacking spaces must be provided to ensure traffic safety is not compromised. A minimum of six (6) stacking spaces is recommended for drive-through facilities associated with eating establishments and a minimum of four (4) stacking spaces for banking, pharmacies, and similar nonfood related drive-through facilities. "Stacking spaces" shall be defined as being twenty feet (20') in length and the width of a one lane, one-way drive. The board may reduce the recommended number of stacking spaces if the applicant can demonstrate that the specific business has unique characteristics such that the recommended number of parking spaces is excessive (i.e., a drive- through that is to be used for pick up only and not ordering).
            (4)   Sufficient on site signage and pavement markings shall be provided to indicate direction of vehicular travel, pedestrian crossings, stop signs, no entrance areas, and other controls to ensure safe vehicular and pedestrian movement.
         b.   Location:
            (1)   In the CB-2 zone and in all subdistricts of the riverfront crossings district located east of the Iowa River, drive-through lanes and service windows must be located on a nonstreet-facing facade. In all other locations where drive-throughs are allowed, this location standard must be met, unless the applicant can demonstrate that a street-facing location is preferable for the overall safety and efficiency of the site, does not conflict with adjacent uses or pedestrian access, and does not compromise the character of the streetscape or neighborhood in which it is located.
            (2)   Drive-through lanes must be set back at least ten feet (10') from adjacent lot lines and public rights of way and screened from view according to the design standards below.
         c.   Design Standards: The number of drive-through lanes, stacking spaces, and paved area necessary for the drive-through facility will not be detrimental to adjacent residential properties or detract from or unduly interrupt pedestrian circulation or the commercial character of the area in which the use is located. The board of adjustment may increase or reduce these standards according to the circumstances affecting the site.
            (1)   To promote compatibility with surrounding development, the number of drive-through lanes should be limited such that the amount of paving and stacking space does not diminish the design quality of the streetscape or the safety of the pedestrian environment.
            (2)   Drive-through lanes, bays, and stacking spaces shall be screened from views from the street and adjacent properties to the S2 standard. If the drive-through is located adjacent to a residential use or property zoned residential, it must be screened from view of these properties to at least the S3 standard. To preserve the pedestrian oriented character of streets in the CB-2 zone and the riverfront crossings district, the board may require the drive-through to be incorporated within the building or be screened with masonry street walls and landscaping. Street walls shall be a minimum of five feet (5') in height and shall be designed to complement the principal building on the site.
            (3)   Multiple windows servicing a single stacking lane (e.g., order board, payment window, pick up window) should be considered to reduce the amount of idling on the site.
            (4)   Stacking spaces, driveways, and drive-through windows shall be located to minimize potential for vehicular and pedestrian conflicts and shall be integrated into the surrounding landscape and streetscape design of the neighborhood in which it is located.
            (5)   Lighting for the drive-through facility must comply with the outdoor lighting standards set forth in chapter 5, article G of this title and must be designed to prevent light trespass and glare onto neighboring residential properties.
            (6)   (Rep. by Ord. 16-4685, 11-15-2016)
            (7)   Loudspeakers or intercom systems, if allowed, should be located and directed to minimize disturbance to adjacent uses. Special consideration should be given to locations adjacent to residential uses to ensure such systems do not diminish the residential character of the neighborhood.

      2.   Location And Height Requirements: All fences, walls, and hedges located within a principal building front, side, or rear setback area or within five feet (5') of a lot line, are subject to the following location and height requirements:
         a.   Except as otherwise allowed or required in chapter 2, article G, "Riverfront Crossings And Eastside Mixed Use Districts Form Based Development Standards", of this title, no portion of a fence or wall more than ten percent (10%) solid shall exceed eight feet (8') in height. The solidity is the percent of the fence over a random area which is made up of solid, opaque material, and which does not allow light or air to pass through. Retaining walls are exempt from the provisions of this paragraph.
         b.   Fences, walls, and hedges must be set back at least two feet (2') from any alley or street right of way line.
         c.   On corner lots, fences, walls, and hedges over two feet (2') in height must comply with the provisions of chapter 5, article D, "Intersection Visibility Standards", of this title.
         d.   Fences and walls that exceed four feet (4') in height are not permitted in the principal building, front setback area on properties zoned residential or on properties located within fifty feet (50') of any property along the same frontage that is zoned residential. However, this height limit is increased to six feet (6') for lots with frontages along an expressway or an arterial street; provided, that the lot is a double frontage lot or a reversed corner lot. Retaining walls are exempt from the provisions of this paragraph. A minor modification may be requested to adjust the height of an entranceway gate in a fence located within a front yard setback area according to the procedures and approval criteria for minor modifications contained in article B of this chapter.
         e.   In riverfront crossings zones and the eastside mixed use district, fences and walls located within private frontage areas are strictly regulated and, if allowed, must comply with the applicable frontage type standards as specified in chapter 2, article G of this title.
      3.   Regulations For Barbed Wire And Electric Fences: Barbed wire and electric fences are subject to the following regulations:
         a.   Barbed wire consists of twisted wires with barbs on each wire. The barbs on each wire must be at least four inches (4") apart. Any barbed wire that does not meet this description is prohibited. Concertina wire is prohibited.
         b.   Except when used for the enclosure of livestock associated with an allowed agriculture use, barbed wire fences are permitted only in the commercial, industrial, and research zones, provided the bottom strand of barbed wire is not less than six feet (6') above grade.
         c.   Except for the enclosure of livestock associated with an allowed agriculture use, electric fences are not permitted in any zone.
         d.   No electric fence shall carry a charge greater than twenty five (25) milliamperes nor a pulsating current lower than one- tenth (1/10) second in a one second cycle. All electric fences must carry the seal of an approved testing laboratory.
         e.   Barbed wire and electric fences are prohibited within five feet (5') of a public sidewalk or within four feet (4') of a street right of way line where a public sidewalk does not exist. In the latter case, however, a barbed wire or electric fence may be installed or constructed along the right of way line if the property owner agrees to move the fence back the required distance within two (2) months after the installation of a public sidewalk. Said agreement must be submitted with the application for a fence permit.
   M.   Home Occupations: There are two (2) categories of home occupations, type A and type B. Type A home occupations are permitted, provided the use complies with the standards in subsections M3 through M9 of this section. Type B home occupations are permitted, provided the use complies with the standards in subsections M3 through M9 of this section, and the operator of the use obtains a home occupation permit from the city as described in subsection M2 of this section. The standards for bed and breakfast homestays, bed and breakfast inns, and childcare homes are specified in other subsections of this section and are, therefore, not subject the provisions of this subsection.
      1.   Home Occupation Types:
         a.   Type A: A "type A home occupation" is one where a resident or residents of a dwelling use the dwelling as a place of work, but no employees or customers come to the site. Examples include artists, craftspersons, writers, and consultants. Type A home occupations also provide an opportunity for a home to be used as a business address but not as a place of work. No permit is required for these uses, but they must comply with all of the other regulations stated herein.
         b.   Type B: A "type B home occupation" is one where a nonresident employee works at the site or where customers frequent the site on a regular basis. Examples include counseling, tutoring, and hair cutting and styling. A home occupation permit is required for these uses.
      2.   Permit Required For Type B Home Occupations: Prior to establishment of a type B home occupation, a home occupation permit must be obtained from the department of housing and inspection services according to the procedures set forth in chapter 8, article B, "Administrative Approval Procedures", of this title. A home occupation permit is required in order to ensure that the applicant is aware of the provisions governing home occupations and that the city has all information necessary to evaluate whether the proposal initially meets and continues to meet the provisions of this subsection.
      3.   Location And Occupancy:
         a.   The home occupation use must be located within a dwelling unit or within a building that is accessory to a dwelling unit.
         b.   The dwelling unit must be the bona fide primary residence of the owner and operator of the home occupation during nonbusiness hours.
      4.   Prohibited Uses: In addition to the uses that would be excluded based on the conditions specified in this subsection, the following uses are specifically prohibited as home occupations:
         a.   Adult business uses.
         b.   Veterinary clinics and kennels.
         c.   Commercial recreational uses.
         d.   Commercial parking.
         e.   Eating and drinking establishments.

         g.   Any type of repair or assembly of vehicles or equipment with internal combustion engines (such as automobiles, motorcycles, scooters, snowmobiles, outboard marine engines, lawn mowers, chain saws and other small engines) or of large appliances (such as washing machines, dryers, and refrigerators) or any other work related to automobiles and their parts.
         h.   Self-service storage.
         i.   Industrial service.
         j.   Any use which changes the fire safety rating of the occupancy separation classification requirements of the structure.
      5.   Commercial Activity:
         a.   No commodities may be sold on the premises except for those produced on the premises or those associated with the home occupation conducted on the premises.
         b.   Type B home occupations are limited to ten (10) clients or customers per day.
      6.   Traffic And Parking:
         a.   The proposed use will not generate a greater volume or type of traffic than what is normally expected in the zone in which it is located; nor will it necessitate parking in excess of what is normally expected in the zone in which it is located. Vehicles used for delivery and pick up are limited to those normally servicing residential neighborhoods.
         b.   No more than one truck associated with the home occupation may be parked at the site. Only light trucks that are less than seven feet (7') in height are permitted. Medium and heavy trucks are prohibited. A "light truck" is a truck with a single rear axle and a single set of rear wheels. The home occupation use must comply with regulations in chapter 5, article A, "Off Street Parking And Loading Standards", of this title, regarding the parking and storage of special vehicles and commercial vehicles and the provisions of title 9, chapter 4, "Parking Regulations", of this code.
      7.   Off Site Impacts: Except for a permitted sign, there must be no indication from the exterior of the dwelling unit or accessory building, such as noise, odor, smoke, dust, excessive outdoor lighting, or outdoor storage of materials, that there is a home occupation use on the premises. No visitors or deliveries to the home occupation use are permitted before seven o'clock (7:00) A.M. or after ten o'clock (10:00) P.M.
      8.   Size: For a home occupation located within a principal dwelling unit, the floor area devoted to the home occupation may not exceed twenty five percent (25%) of the total floor area of the principal dwelling (the floor area of an attached garage is not included in the calculation of total floor area of the dwelling). This twenty five percent (25%) limit applies regardless of whether the home occupation is located within the principal dwelling unit or within an accessory building. For example, for a property where the principal dwelling contains two thousand (2,000) square feet of floor area, a home occupation would be limited to five hundred (500) square feet regardless of whether it was located within the dwelling or within an accessory building.
      9.   Nonresident Employees: Nonresident employees are prohibited, except as approved by the building official as a minor modification to the home occupation use, according to the approval criteria and procedures for minor modifications as set forth in chapter 4, article B of this title.
