Section 3.8.3(4) of the Transitional Land Use Code sets that restriction for home occupations reviewed under the code used before the City's current Land Use Code took effect May 17, 2024.
(4)There shall be no exterior advertising other than the residential sign allowed in Section 3.8.7.1(D)(5)(a) of this Code. ... Section 3.8.7.1(D)(5)(a): "One (1) optional residential sign per street-facing building elevation of a residential building not exceeding four (4) square feet in area;"

Full Breakdown
1(D)(5)(a) of the Sign Code. That cross-referenced provision allows a residential building one optional sign per street-facing building elevation, and the sign cannot exceed four square feet in area; it is one of the sign-permit exceptions the Sign Code lists, meaning it can go up without a separate sign permit but must still meet the size and placement limit. 1(G)(2) separately bans portable signs outside Chapter 24, Article IV, wind-driven signs other than flags, and any off-premises signage citywide, so a home-based business also cannot rent advertising space on a nearby lot or vehicle to work around the four-square-foot cap.
3, applied to home occupation applications and licenses reviewed under the code Fort Collins used before its current Land Use Code, adopted by Ordinance No. 055, 2024, took effect for applications submitted on or after May 17, 2024.
Violations & Fines
Posting a larger sign, a second sign, or any off-premises advertising for a home occupation violates Section 3.8.3(4) and can trigger the license revocation process under Section 3.8.3(11); the Zoning Director can pull the home occupation license for any breach of the conditions in paragraphs (1) through (8). Sign Code violations found under Section 3.8.7.1(G) for prohibited sign types, such as portable or off-premises signs, carry separate code-enforcement citations independent of the home occupation license.
