UDO 154-9-090.F lets a suburban home occupation operate by right if it is incidental and subordinate to the residence, is conducted within the principal dwelling, and does not exceed the lesser of 1,000 square feet or 40% of the dwelling's gross floor area. On-site customer or client visits are prohibited, as are outdoor display and listed uses (restaurants, vehicle repair, animal boarding, etc.). Rural home occupations (154-9-090.G) need a special exception and a lot of at least 4.5 acres. Day care homes and bed-and-breakfasts are exempt from home-occupation rules.
