Full Breakdown
06. 08 and 9814, and the permit is non-transferable: it authorizes only the named person to run only the approved occupation. Permits run for one calendar year, require the Council-set fee for issuance and renewal, and the Planner can suspend or revoke one for violating any condition, operating a different occupation than approved, or running the business in a disorderly manner or to the public's detriment. 08 sets the operating conditions. The operator needs a current business license under Article VI, Chapter 2, and written consent from the property owner if the operator does not own the home.
The occupation must remain a clearly incidental, accessory use to the residence and be conducted entirely inside the principal structure, except horticulture, which may be conducted outdoors; garages and accessory structures cannot be used for the business itself. No exterior alteration, signage, lighting, or other change may let the home be recognized from outside as a place of business, and floor area devoted to the occupation, including storage, is capped at the lesser of 10% of the structure or 250 square feet.
Violations & Fines
Running a home business without a valid Home Occupation Permit, exceeding the 250-square-foot/10% floor-area cap, or violating any § 9408.08 condition lets the City Planner suspend or revoke the permit outright. Continued operation after revocation is a zoning violation the Community Development Department can refer for code enforcement citation or abatement, and a lapsed or unpaid annual renewal fee makes the occupation unpermitted the day the prior permit expires.
