Summary
A home occupation in unincorporated Williamson County gets one permanent sign under Table 18.07-1: a ground sign, or a wall sign substituted for it. Projecting, entrance and auxiliary signs are not permitted for the use, and Section 18.08(B)(10) treats the sign as a permanent commercial message rather than a temporary sign.
TABLE 18.07-1: PERMITTED PERMANENT SIGNS ... USE TYPES: Single-family dwellings, Mobile Homes, Accessory Dwelling Units (Residential), Additional Principal Dwellings, Agricultural Product Sales, Day Care Centers Accessory to an Institutional Use, Group Child Care Homes, Family Child Care Homes, Home Occupations, Residential Business -- GROUND A, WALL B, PROJECTING N, ENTRANCE N, AUXILIARY N. Abbreviations: A = Only one Ground Sign Permitted. B = Wall Sign(s) may be substituted for a permitted Ground Sign. N = Not Permitted. ... (10) Home occupation or residential business signs shall be considered permanent commercial messages, and therefore do not count toward allowed temporary signage.

Full Breakdown
07-1: Permitted Permanent Signs with single-family dwellings, mobile homes, additional principal dwellings and Residential Business under one row. That row's Ground column shows 'A,' meaning only one ground sign is permitted; the Wall column shows 'B,' meaning a wall sign may be substituted for that one permitted ground sign; Projecting, Entrance and Auxiliary all show 'N,' not permitted. So a home-based business operator can put up exactly one sign, either a ground sign or a wall sign in its place, and nothing more. 08(B)(10) then draws a firm line between that permanent home occupation sign and the temporary residential sign allowance covered elsewhere in the same section: home occupation or residential business signs shall be considered permanent commercial messages, and therefore do not count toward allowed temporary signage.
That means a home business cannot stack its permanent identification sign on top of the five-sign, 30-square-foot temporary sign allotment available for garage sale or real estate signs on the same lot; the two categories are kept separate. 06 requires it be maintained in a safe condition and not obstruct driver or pedestrian sightlines. 07-1.
Violations & Fines
Installing more than the one permitted ground or wall sign for a home occupation, or installing a projecting, entrance or auxiliary sign for the use, violates Table 18.07-1 and Section 18.08(B)(10), a violation of the Ordinance under Article 22.03. The Codes Compliance Director enforces sign standards and may order an unsafe or noncompliant sign corrected or removed under Section 18.06(G)(2); a violator is guilty of a misdemeanor fined $10 to $50 per offense under Tenn. Code Ann. § 13-7-111, each day a separate offense.
