THE HOME OCCUPATIONAL SECTION OF THE COLUMBUS ZONING CODE
Section 3337.24 of the Columbus City Code permits a home occupation as an accessory use if it is compatible with the residential character of the neighborhood in which it is located, and is conducted so as not to have an adverse effect on the average neighbor under normal circumstances; to set standards by which to judge the operation of such use; and to prohibit uses that are incompatible with permissible uses in residential districts. A home occupation may be an accessory use in any residential district subject to the following conditions:

1. Any home occupation use shall be confined to the principal residence of the individual so engaged, shall be excluded from any yard or accessory building, and shall be clearly incidental and subordinate to the primary residential use.

2. No alteration shall be made in either the internal or external structural form of the residential building or the external appearance for purposes of home occupation. The removal of partitions or floors or parts thereof, shall be construed as an alteration of the external or internal structural form, and is, therefore prohibited.

3. No evidence of any home occupation shall be visible from off the lot where it is conducted except for no more than one permissible graphic installed pursuant to Section 3377.32 C.C.

4. No more than 20 percent of the livable area of any residence shall be used for home occupation.

5. No person other than a permanent resident of the dwelling unit shall be engaged in or employed at any home occupation within such dwelling unit except that in connection with the practice of a profession which can be practiced only with the assistance of supportive personnel, one person not residing in the dwelling unit may be employed. Profession is limited herein to architect, attorney, clergy, dentist, engineer, physician, or surgeon.

6. No storage of equipment or materials used in a home occupation shall be outside the principal residence.

7. No change shall be made in any utility line, meter, or service to accommodate a home occupation and utility use shall not unreasonably exceed that normally or previously used at such residence.

8. No equipment or process shall be used in any home occupation which emits radiation or creates noise, vibration, glare, fumes, odors, or electrical interference detectable to the normal senses off the lot used for such home occupation. In the case of electrical interference, no equipment or process shall be used which creates visual or audible interference.

9. No traffic shall be generated by any home occupation unreasonably greater in volume or different in nature than would otherwise normally occur in the residential neighborhood in which it is located.

10. No wholesale or retail business shall be conducted in a dwelling unit.
