Mission Viejo, CA Home Business: Signage Rules (2026)

Home occupations in Mission Viejo get no exception for on-site signage the way many home-based business ordinances allow a small identification sign. Sec. 020(b)(5)(a)(xi) states flatly that "there shall be no advertising signs on or off the premises," meaning even a small nameplate at the curb or a sign posted elsewhere in the city advertising the business is not permitted. Clause (xii) closes an obvious workaround by separately prohibiting "commercial advertising which identifies the site of the home occupation by street address," so a business card, website listing, or classified ad that publishes the residence's address as the place of business also violates the standard, independent of whether a physical sign exists.

These signage rules sit inside the broader list of operating standards in clause (a), which also requires the home occupation to leave the dwelling's exterior appearance unchanged and to avoid any display or sale of merchandise on the premises, reinforcing that the business is meant to be undetectable from the street. 5 through RPD 80, since Sec. 020(b)(5) is one of the zone-specific standards that applies to all of them. There's no size or design exception carved out anywhere else in the section for a discreet identification sign.
