Class I Home Occupations shall be permitted in all zoning classifications in which residential uses are permitted subject to the following:
(a) The Class I Home Occupation shall be secondary to the use of a dwelling unit for residential purposes. No more than one room of the dwelling or 150 square feet, whichever is less, may be used in connection with the home occupation.
(b) On the premises, retail sales shall be prohibited.
(c) Only persons permanently residing on the premises shall be employed in or engaged in or provide services to the Class I Home Occupation.
(d) No more than one Class I Home Occupation per resident shall be permitted within any single dwelling unit.
(e) A Class I Home Occupation shall be carried on wholly within the principal building. No home occupation nor any storage of goods, materials, or products connected with a home occupation shall be allowed in accessory buildings or garages, attached or detached.
(f) There shall be no exterior indication of the home occupation or of any variation from the residential character of the principal building.
(g) There shall be no exterior storage of materials to be used in conjunction with a home occupation.
(h) There shall be no deliveries to or from a Class I Home Occupation, except by the occupant, except by U.S. Mail or by courier, and by no customers or clients.
(i) The home occupation shall not generate any additional pedestrian or vehicular traffic not normally associated with the residential use of the dwelling.
(j) A Class I Home Occupation shall produce no offensive noise, vibration, smoke, electrical interference, dust, odors, or heat. A Class I Home Occupation as provided by this section shall be completely contained within the principal building. Any noise, vibration, smoke, electrical interference, dust, odors, or heat detectable beyond the property lines or beyond the walls of the dwelling unit, if the unit is part of a multifamily structure, shall constitute a violation of the terms of this provision. The judgment of the Zoning Official shall be considered decisive and final in this matter unless formally appealed to the Planning Commission within forty-five days of the zoning official's written determination.
