Johnston County, NC Home Business: Zoning & Home Occupation Permits (2026)

Section 14-6 of the Johnston County Code defines a home occupation as work customarily conducted for profit within a dwelling unit by its occupants, citing home offices, sewing and tailoring, artistic painting, tutoring, catering, and barber or beauty work as examples. Ten numbered standards govern every home occupation in unincorporated Johnston County. The use must stay clearly incidental and subordinate to the residence, and the workspace, including any accessory building used for the business, cannot exceed 500 square feet or 25 percent of the dwelling's floor area, whichever is greater.

The building's outside appearance cannot change, and the only allowed sign is a single non-illuminated sign of no more than four square feet mounted flat against the wall. Only one person besides the household's occupants may work in the business, and only one business vehicle is permitted, capped at 14 feet in height with a cargo area or work platform no longer than 14 feet; dump trucks, tractor-trailers, tankers, and wreckers are barred outright. The occupation cannot generate noise, vibration, glare, fumes, or electrical interference detectable off the lot, cannot display products visible from the street, and cannot make merchandise sales or manufacturing its primary function except for baking, sewing, or crafts normally made at home.

Music, dance, or academic tutoring is capped at four students at a time, and no equipment or process may change the structure's fire rating. If planning staff determines a proposed home occupation cannot meet these ten standards, the applicant may still apply to the board of adjustment for a conditional permit rather than being turned away outright.
