Summary
A home business in unincorporated St. Louis County gets no separate sign allowance: Section 6.20.B.6 requires all signs to conform to outdoor sign standards found in Article VI, Section 6.12, so a home business sign is capped at the same size, setback and illumination limits, including the dark-sky lighting standard, that apply to any other outdoor sign in that zone district.
B. Permit Required: ... Home businesses may be allowed in certain zone districts (FAM, MU, SMU, COM, LSO, and LCO) with a performance standard permit with the following standards: 6. ... All signs shall conform to outdoor sign standards found in Article VI, Section 6.12.
Full Breakdown
12. B: a land use permit is required, two outdoor signs are allowed per lot meeting the district's minimum lot area and width, each capped at 64 square feet in surface area and 35 feet in height, and every freestanding sign must sit back at least ten feet from the right-of-way, matching the district's property line setback for accessory structures. 3 illumination rules travel with it too: sign lighting cannot be aimed at a roadway or cause glare that impairs a driver, cannot obscure an official traffic sign, and must use downward, shielded or otherwise dark-sky compliant fixtures to the greatest extent possible absent a site-specific reason.
B, including the smaller water-facing sign cap and the ban on an electronic sign visible from public waters. Either way, a home business sign advertising more than the business's presence on-site does not get a size or setback exception because it is tied to a home occupation rather than a standalone commercial use.
Violations & Fines
A home business sign that exceeds Section 6.12's size or height caps, skips the ten-foot right-of-way setback, or uses lighting that isn't shielded or dark-sky compliant is a sign-code violation, not just a home-business condition failure, and is enforced under Section 8.2: the Director orders correction, and an owner who doesn't comply within 30 days risks permit revocation or a misdemeanor referral to the County Attorney.
