Residential fences are permitted in any yard and may be constructed on property lines in residential districts except as herein provided. Fences or walls located in required yards shall not in any case exceed a height of six feet, except such fences or walls shall not exceed a height of four feet in the front yard. Security or screening fences are permitted on the property lines in the industrial districts, but shall not exceed ten feet in height.

   A “swimming pool,” as regulated herein, is any pool or open tank not located within a completely enclosed building and containing or normally capable of containing water to a depth at any point greater than 1½ feet. No swimming pool shall be allowed in any residential district except as an accessory use and unless it complies with the following conditions and requirements:

   1.   The pool is intended and is to be used solely for the enjoyment of the occupants of the principal building of the property on which it is located and their guests.

   2.   The pool shall not be located in a required side yard or closer than ten feet to any property line of the property on which it is located, provided that pump and filter installations shall be located not closer than 20 feet to any property line.

   3.   The swimming pool or the entire property on which it is located shall be so fenced or walled as to prevent uncontrolled access by children from the street or from adjacent properties. Such wall or fence shall be not less than five feet in height.

   The location of garages and accessory buildings shall be governed by the following:

   1.   In any residential district a private garage is permitted in the side or rear yard on the same lot with a dwelling, either as a separate building, or a separate room within or attached to the dwelling. When wholly or partially within the limits of the side yard and attached to the principal building or a separate room within a principal building, such garage shall be considered as a part of such principal building and shall conform to all yard and space requirements as specified in this chapter for principal buildings. When wholly or partially within the limits of a rear yard and attached to a principal building or a separate room within a principal building, such garage, if one story in height, may extend into the rear yard the distance its rear wall is beyond the rear wall of the principal building.

   2.   No private garage shall exceed 864 square feet in area or have a side wall height greater than 10 feet or a peak height greater than 18 feet. The garage must be compatible with the architecture and construction of similar dwellings and other buildings in the neighborhood. Metal buildings of pole type or machine shed type construction are not permitted. The building must be sided with a house type siding and the roof shall be the same as the existing area building. No galvanized or colored steel siding or roofing is permitted.

   3.   In any business district, public or private garages or accessory buildings are permitted on any part of the lot.

   4.   Each detached private garage or accessory building shall be not less than five feet from a party lot line or alley line. When any part of such building is within 50 feet of any street or public place upon which the lot abuts, such building shall be not less than five feet from any lot line which serves as the front portion of a side lot line to any adjoining property. When a garage or carport is entered directly from an alley, it shall not be located closer than 10 feet from the alley right-of-way line.

   5.   No detached garage or accessory building is permitted within the limits of a front yard, unless entirely below natural ground level.

   6.   If any portion of a detached garage or other accessory building is within a side yard of a principal building on the same lot, such garage or building shall not be nearer to the side lot line than would be required for the building wall of a principal building on the same lot. In interpreting this regulation each 12 feet in height of the accessory building shall be considered a story.

   7.   No detached garage or accessory building may be placed in any rear yard or any side yard so that any part of such building is nearer a street line than is permitted for a wall of a principal building on the same lot or abutting lot.

   8.   Accessory buildings or garages within a rear yard may occupy not more than 35 percent of such area. Accessory buildings or garages must be erected separately from and 10 feet distant (into the rear yard) from the principal structure. No accessory building or garage shall be constructed upon a lot until the construction of the principal building has been actually commenced, and no accessory building or garage shall be used unless the principal building on the lot is also being used. Accessory buildings or garages may be connected to the principal building by a breezeway with setbacks for the principal structure. An addition may be made to an existing principal structure which extends past the front of an existing legally established detached accessory structure or garage, provided no connection or attachment is made between the existing structure and the addition unless setbacks can be met as required for a principal structure.

   9.   If an adjacent lot is built upon, an accessory building or garage must be entirely to the rear of the line of any principal building on such adjacent lot. No accessory building or garage shall degrade adjacent property by obstructing views, inhibiting solar access, or hindering ventilation. There shall be no more than one detached accessory building or garage per lot.

   10.   Structures less than 100 square feet and not on permanent foundation, shall be exempt from the requirement of obtaining a construction permit provided only one such structure shall be permitted per residential dwelling and located only in rear and side yards not closer than two feet from the property line. Such structures may include tool sheds, dog houses, play houses, ice houses, air conditioning units, satellite dish antennas not to exceed 36-inch diameter, and similar structures as determined applicable by the Zoning Administrator. No dog house, play house, in addition to hunting or fishing structures, ice fishing shacks or other mobile or transient structures intended for used other than permanent storage shall be used for purposes of an accessory building or use. Accessory buildings larger than 100 square feet in size which require a Building Permit shall be required to use the same construction materials or have the same appearance of the principal use building or structure on the lot.

   11.   Membrane Storage Structures may be erected on a temporary basis to facilitate special events or construction of permanent structures. Membrane Storage Structures will require a building permit and shall be permitted for no more than six months, non-renewable. Permanent membrane storage structures are not permitted on any residential properties.

   12.   On-Site Storage Structures may be utilized on a temporary basis in connection to construction work of a permanent structure on-site in any district during the period that the construction work is in progress, but such temporary structure shall be removed within 30 days after completion or abandonment of the construction work.

   A mobile home park may be permitted in any residential or business district only with Council approval. The owner or agents of any tract of land comprising an area of not less than five acres may submit to the Council a plan for the use and development of all such tracts for mobile home parks as provided for in Chapter 146 of this Code of Ordinances. The development plans shall be referred to the Planning and Zoning Commission for study and report. If no report is transmitted within 60 days of referral, the City Council may take action without further awaiting the report. If the Commission approves the plans, they shall then be submitted to the Council for consideration and action. The approval and recommendations of the Commission shall be accompanied by a report stating the reasons for approval and specific evidence and facts showing that the proposed mobile home park plan meets the conditions provided for in this Zoning Code. (See Chapter 146 of this Code of Ordinances for further regulations governing mobile home parks.)

   If actual construction has been started on any building at the time of the passage of the effective date of this chapter, nothing contained herein shall require any change in the plans, construction or designated use of any such building or part thereof.

   Open porches or decks may extend into a required front yard a distance not exceeding ten feet. Open porches or decks constructed at a height not exceeding 24 inches above established grade may extend into any required yard. Bay windows, cantilevered extensions of walls or similar projections may extend into required front or rear yards a distance not exceeding 24 inches.

   Boat hoists may be stored in rear and side yards when space permits. A maximum of four boat hoists shall be stored per parcel of land.
