Greenville County, SC Home Business: Signage Rules (2026)

Three distinct constraints are baked into this single sentence. First, the count is capped at one — a second nameplate, a sandwich board on the lawn, a vehicle wrap parked permanently in the driveway, or a banner across the porch all violate the rule. Second, the size cannot exceed two square feet; the parenthetical "(i.e. 1' x 2')" is the staff-interpretation example, not a license to use a 6" x 24" strip or any other 2-sq-ft configuration that creates the visual impact of a commercial sign. Third, the mounting is restricted: "mounted flat against the wall of the principal building" — meaning no projecting brackets, no monument-style sign in the yard, no attachment to fences, mailboxes, or accessory structures (garages, sheds, detached studios).

Section 6:2(13) reinforces the no-commercial-presence intent with several other provisions that interact with the signage rule: (B) the occupation may be conducted only within the principal structure; (E) no display of merchandise shall be visible from the street; (F) no outdoor storage is allowed; (G) no alteration of the residential character of the premises is permitted; and (H) the occupation shall not be a nuisance or cause any undue disturbance in the neighborhood. Read together, these mean that any external indication of commercial activity beyond the 2-sq-ft nameplate — flags, A-frames, vinyl wraps, light boxes, illuminated signs, internally lit channel letters, etc. — is prohibited even if the sign itself would comply.

Greenville County Code Enforcement (864-467-7425) handles complaints and citations. Compliance with the home-occupation signage rule is also a precondition for keeping any business license tied to the residential address; an unpermitted sign is one of the most common triggers for a zoning complaint that escalates into broader review of whether the use still qualifies as a home occupation at all.
