Vacaville, CA Home Business: Signage Rules (2026)

120(D)(1) sets the appearance standard for every home occupation in the City: the residential appearance of the dwelling unit in which the home occupation is conducted must be maintained, and no exterior indication of a home occupation is permitted. That single sentence functions as an outright sign ban for home-based businesses, since any exterior sign, by definition, is an exterior indication of the occupation. 8). Together these provisions mean a Vacaville home business must be invisible from the street, no advertising sign, no product display, no marked vehicle parked out front beyond the one permitted work vehicle, and no altered entrance suggesting commercial use.

A resident who wants visible signage for a business must relocate that business to a commercially or industrially zoned property, where the City's separate sign standards under the zoning ordinance apply instead. The Director of Community Development can grant exceptions to the section's operational standards, but only on findings that the exception won't conflict with the section's purpose and that special circumstances justify it; those findings are not aimed at unlocking signage specifically.
