Summary
A home-based business in unincorporated Yuba County may display exactly one wall sign, capped at four square feet in area and six feet in height, without needing a zoning clearance or sign permit. County Code § 11.27.030(11) exempts that single sign from the county's general sign-area and review requirements.
The following signs or modifications to signs do not require a Zoning Clearance or other review by the Planning Department, nor shall the area of such signs be included in the maximum allowable sign area measurement for the purposes of this Chapter. These exceptions shall not be construed as relieving the owner of the sign from the responsibility of the safe erection and safe and attractive maintenance of the sign, of obtaining a building permit where applicable, or of compliance with applicable provisions of this Chapter or any other requirement of this Code. ... (11)Home occupation signs. Permitted home occupations are allowed one wall sign not to exceed four square feet in area and six feet in height.

Full Breakdown
Section 11.27.030 lists the signs the county exempts from zoning clearance and from the maximum sign area calculation elsewhere in Chapter 11.27, and item (11) is written specifically for home businesses: "Home occupation signs. Permitted home occupations are allowed one wall sign not to exceed four square feet in area and six feet in height." The exemption only reaches a sign meeting those exact limits: one sign, wall-mounted, four square feet, six feet tall. Anything larger, freestanding, or in addition to that one sign falls outside the exemption and is instead measured against the general standards in §§ 11.27.070 and 11.27.080 and requires the zoning clearance and, where applicable, building permit process in § 11.27.050.
Even though the home occupation sign doesn't need a zoning clearance, § 11.27.030's opening paragraph makes clear the exemption "shall not be construed as relieving the owner of the sign from the responsibility of the safe erection and safe and attractive maintenance of the sign, of obtaining a building permit where applicable." The county also allows a separate, broader small-sign exemption under § 11.27.030(20): any business or residence can display up to two signs, each no larger than six square feet and five feet tall, on a freestanding structure, window, or wall, which a home business could use in addition to its dedicated four-square-foot home occupation sign.
Violations & Fines
A sign exceeding the four-square-foot, six-foot home occupation exemption is treated as a non-exempt sign requiring zoning clearance and, if applicable, a building permit; installing it without that review is a Code violation. Section 11.27.160 lets the Planning or Building Director declare non-compliant signs public nuisances and remove them through the abatement procedure in Chapter 7.36, Property Maintenance Ordinance, which carries its own infraction fines and continuing-violation penalties.
