Home occupations are permitted in any dwelling unit, subject to the following provisions:

A. Use limitations. An occupation which does not comply with the following criteria shall not be deemed a home occupation:

1. Not more than one person other than members of a family residing on the premises, shall be engaged in such occupation. If more than one nonfamily member is to be en-gaged in such occupation, a conditional use permit is required.

2. The use of the dwelling unit shall be clearly incidental and subordinate to its use for residential purposes by its occupants. Not more than an area equal to one-fourth of the gross floor area of the primary residence shall be used for the home occupation. If an accessory building is proposed for use, only an area not to exceed one-fourth of the gross floor area of the primary residence shall be used. Additional area in both cases is allowed only by granting of a conditional use permit.

3. No exterior display, including window displays, shall be permitted.

4. No outdoor storage shall be permitted.

5. Exterior signs shall be restricted to those permitted in the zone in which the home occupation is located.

6. There shall be no other exterior indication of the home occupation.

7. No home occupation shall be conducted in such a manner, and/or no materials or mechanical equipment shall be used, which will be detrimental to the residential use of said residence or cause a nuisance to surrounding residences, because of vibration, noise, dust, smoke, odor, interference with radio or television reception, or other factor.

8. Any need for parking generated by the conduct of such home occupation shall be met off the street and other than in a required front or side yard.

9. The home occupation shall not generate pedestrian or vehicle traffic in excess of that which is characteristic of the neighborhood in which it is located. Vehicle traffic would not be increased by more than one at a given time or by more than eight all day.

10. No home occupation shall generate as a by- product for disposal or cause to be dumped in a city sewer any hazardous waste including chemicals and cleaners, other than the volume and types that would be normally generated by a typical single family home.

11. No home occupation shall cause an increase in any one or more utilities (water, sewer, garbage) so that the combined total use for dwelling and home occupation purposes exceeds the average for residences in the neighborhood. (Ord. 523 § 1(part), 1989)
