Summary
A home business in unincorporated Carroll County may post a sign up to three square feet naming the occupation without needing a zoning certificate, under Zoning Code § 158.111(A). Larger or off-premises advertising for a home occupation falls outside this exemption and must meet the county's other sign standards.
§ 158.111 SIGNS PERMITTED WITHOUT ZONING CERTIFICATE. The following signs are permitted without a zoning certificate in any district, provided that the following conditions are adhered to: (A) Signs indicating the name and/or premises or accessory use of a home for a home occupation or professional purposes, not exceeding three square feet in area; (B) Signs not exceeding 30 square feet on a farm advertising farm products primarily grown on the premises, provided that they are located off the highway right-of-way and do not interfere with traffic visibility;

Full Breakdown
110 makes the county's sign rules apply to all signs located in the unincorporated areas of the county; incorporated towns inside Carroll County regulate their own signage separately. 111, a list of sign types is permitted in any zoning district without first obtaining a zoning certificate, provided listed conditions are met. Division (A) covers signs indicating the name and/or premises or accessory use of a home for a home occupation or professional purpose, capping the area at three square feet. By comparison, the code allows a farm sign advertising products grown on the premises up to 30 square feet under division (B), showing the home-occupation cap is a deliberately tighter limit tied to residential character.
Anything larger than three square feet advertising a home business, or a freestanding advertising sign not tied to the accessory home-occupation use itself, falls outside this no-certificate exemption and must be reviewed as a regular sign application subject to the district's general sign standards administered by the Zoning Administrator. The Zoning Administrator enforces Chapter 158, including this signage subchapter, and maintains the county's zoning certificate and permit records.
Violations & Fines
Signs exceeding the three-square-foot home-occupation exemption without the required zoning certificate are treated as zoning violations under § 158.999: a fine of up to $1,000 for a first-tier violation of the chapter, plus a separate civil-citation schedule starting at $50 for a first offense, $100 for a second, $200 for a third and $500 for each later offense, with every day the sign remains a separate offense. Decisions of the Zoning Administrator may be appealed to the Board of Zoning Appeals within 30 days under § 158.133(D).
