Midway City, CA Home Business: Signage Rules (2026)

Signage for home-based businesses in unincorporated Orange County is addressed directly in the Home occupations section of the County Comprehensive Zoning Code (Section 7-9-104). Among the general requirements in subsection (c), the code states plainly in subsection (c)(8): 'There shall be no signs.' This is reinforced by subsection (c)(3), which requires that 'There shall be no exterior evidence of the conduct of a home occupation,' and subsection (c)(7), which prohibits any change to the principal character or use of the dwelling unit. Together these provisions mean a home occupation may not display any business sign, nameplate, banner, window lettering, or other outward advertising on the property. The intent stated in the purpose clause is to keep incidental and accessory home uses compatible with the residential neighborhood and to protect residents' rights to engage in home occupations that are harmonious with a residential environment. Any commercial signage advertising the home business would constitute prohibited exterior evidence. Larger or freestanding business signs are governed by the separate County sign regulations and are not available for home occupations in residential districts. Residents who want any form of on-site advertising should instead consider operating from a commercially zoned property, where the County's commercial sign standards would apply.
