Columbia, SC Home Business: Zoning & Home Occupation Permits (2026)

Sec. 3(d)(6) of the Unified Development Ordinance sets the standards for any home occupation in Columbia. The person running the business must be a full-time resident of the dwelling, and the operation can employ no more than two people on the premises who are not full-time residents. Home occupations may use no more than 25 percent of the dwelling unit's floor area or 1,000 square feet, whichever is less, and the use must stay clearly incidental and subordinate to the home's residential purpose. The business has to be conducted entirely inside the principal structure or a fully enclosed, lawfully approved accessory structure; it can't operate out of an accessory dwelling unit, and it can't take over space needed for required parking.

Goods can't be sold on site except items incidental to a service the business already provides, such as a hairdresser selling shampoo, and no equipment or process may create noise, vibration, glare, fumes, odors, or electrical interference detectable off the lot. Outdoor storage or display of goods tied to the home occupation is barred outright, and the code specifically bans repairing or maintaining motorized vehicles as a home occupation. Two specific businesses, beauty salons and barbershops, are not allowed as home occupations by right; they instead need a Special Exception Permit under Sec.

5(e) before opening. The Zoning Administrator reviews compliance with these standards when the city issues the underlying business license or investigates a complaint, and any violation ties back into Article 8's general zoning enforcement process.
