A hobby may be pursued as an accessory use by the occupant of the premises purely for personal enjoyment, amusement or recreation, provided that the articles produced or constructed are not sold in the ordinary course of business either on or off the premises, and provided such use will not be obnoxious or offensive by reason of vibration, noise, odor, dust, smoke, gas, or otherwise.

    Group homes for foster care.

    Group homes for mentally or physically handicapped, under the following restrictions:

    (1)    Any such group home shall not be located within a one thousand (1,000) foot radius of another such group home in any specific single-family neighborhood.

    (2)    Before operating such group home, the owner or operator of the home shall register with the Public Works Community Development Department and shall sign an affidavit certifying that the home will be in compliance with subsection (1) above.

    (3)    The exterior appearance of the home and property shall be in reasonable conformance with the general neighborhood standards.

Home occupations which are compatible with the residential character of the neighborhood will be permitted, however, in order to promote peace, quiet and freedom from excessive noise, excessive traffic, nuisance, fire hazard, and other possible effects of commercial uses being conducted in residential areas all home occupations must meet the following restrictions:

    (1)    A home occupation shall be incidental to the use of a dwelling unit for residential uses. No person other than a person residing at the dwelling unit shall be directly involved with or work in the home occupation. If the home occupation employs persons to work at other locations, the dwelling unit shall not be used as an assembly point for any employees who may work at sites outside of the dwelling.

    (2)    No alteration of the residential appearance of the premises shall be made, including the creation of a separate entrance to the dwelling or utilization of an existing entrance exclusively for the home occupation.

    (3)    No more than twenty (20) per cent of the total floor area of the dwelling unit and garage shall be devoted to the home occupation. A garage shall not be used for a home occupation if such use has the effect of eliminating required parking.

    (4)    The home occupation shall be conducted entirely within the dwelling unit or garage and no stock in trade shall be displayed or visible outside, or stored outside of any building, nor shall any raw materials, tools or appliances or waste products be stored outside of any building.

    (5)    Signs may be used for identification or advertisement of the home occupation but such signs must be attached flat to the structure, may not be larger than one square foot and may not be illuminated.

    (6)    No power other than electric shall be used and no single machine shall draw more than one-half horsepower and not more than one horsepower total shall be used,

    (7)    There shall not be conducted on the premises the business of selling stocks of merchandise, supplies, or products, provided that orders previously made by telephone or at a sales party may be filled on the premises; that is, direct sales of products off display shelves or racks is not allowed, but a person may pick up an order placed earlier as described above.

    (8)    The use shall not generate traffic in volumes greater than would normally be expected in a residential neighborhood. For purposes of this section, the normal volume of traffic generated by a single-family dwelling shall be defined as twelve vehicle trips to and/or from the dwelling unit per twenty-four-hour period. The use shall not use commercial or business vehicles to deliver finished products from the dwelling unit. All parking necessarily generated by the use shall be off the street in accordance with section 29-30 of this chapter.

    (9)    The use shall not produce noise, obnoxious odors, vibrations, glare, fumes or electrical interference detectable to normal sensory perception outside the structure.

    (10)    No toxic, explosive, flammable, combustible, corrosive, radioactive or other restricted materials may be used or stored on the site.

    (11)    All persons desiring to have a home occupation must first present appropriate plans to the building regulations supervisor detailing how the dwelling will be used or altered to accommodate the use. Thereafter, whenever any permit or license is to be renewed, the dwelling may be inspected to determine how it has been altered to accommodate the use.

        Abatement. Any home occupation which does not comply with the above restrictions shall be brought into compliance within thirty (30) days of the notice of the deficiency. It shall be unlawful to fail to comply with the above restrictions after notice.

If the council shall approve the development plan by ordinance, such plan shall be filed with the permanent records of the city. The development plan shall show existing and future buildings, parking areas, streets and drives, athletic facilities, and other features which may affect surrounding property or the public interest. The director of public works community development shall determine, or cause to be determined, that any building or structure hereafter constructed substantially conforms to the approved development plan prior to the issuance of a building permit.
