Riverside prohibits any sign or commercial advertising for a home occupation. Municipal Code Section 19.485.040(J) bars signage outright, backed by a no-external-visible-evidence rule in subsection (C), and Section 19.485.050 forecloses any variance to add it.

Full Breakdown
' There's no size or placement exception, no window sign, yard sign, or advertising display is permitted for a home-based business anywhere in the city's residential zones. 040(C), which requires 'no external visible evidence of the home occupation,' so a Riverside home business has to be functionally invisible from the street. 620 (General Sign Provisions), which allows businesses in commercial zones to install monument, wall, and other permitted sign types, none of that applies once a business operates as a home occupation rather than from a commercially zoned site.
030 otherwise allows to operate from the home. 485: home occupations are permitted only to the extent they stay compatible with, and invisible within, the surrounding residential neighborhood.
Violations & Fines
Posting any sign or commercial advertising for a home occupation violates Section 19.485.040(J), a Zoning Code violation Riverside's Code Enforcement Division enforces under Section 19.070.020 through Notices of Violation and field citations. Section 19.040 makes the underlying unlawful use itself a citable offense, and because Section 19.485.050 bars modifications to the standard, there is no path to a sign permit for a home-based business.
