Summary
El Cajon bans signage entirely for home occupations: Municipal Code Sec. 17.225.050(C) requires that a home occupation display no sign or other advertising of any kind, one of ten mandatory conditions a home-based business must meet to legally operate in the city.
A home occupation shall meet each of the requirements set forth in subsections (A) through (J) of this section, unless otherwise excepted by subsection (K), and further shall be subject to subsections (L) and (N) of this section. ... C. One for which no sign or other advertising is displayed; ... F. One in which there is no alteration of the residential character of the premises; ... N. Notwithstanding the above, any home occupation may be revoked by the director of community development upon the violation of any requirements of this Title or any conditions of approval, unless the violation is corrected within five days of giving written notice thereof.

Full Breakdown
Municipal Code Sec. ' Unlike zones that permit a monument or wall sign up to a set square footage, a home occupation gets none at all, not a window sign, yard sign, vehicle wrap advertising the business, or off-site directional sign. The prohibition sits alongside the rest of the section's residential-character protections: subsection F bars any alteration of the residential character of the premises, and subsection G confines customer and client contact to off-site meetings or communication by mail, telephone or electronic media, reinforcing that the operation must stay visually indistinguishable from a private home.
A business is still required to hold a valid business license, obtained and annually renewed under subsection J and Title 5 of the municipal code, but that license does not authorize any exterior or interior advertising display. The community development director enforces the no-sign condition as part of the section's overall compliance requirement: violating subsection C is treated the same as violating any other home occupation standard, and the director may revoke the home occupation approval unless the violation is corrected within five days of written notice under subsection N.
30. The section was last amended by Ord. 5131 Sec. 31 in 2022, and applies citywide to any occupation conducted within a dwelling by its inhabitant, with no zone-based exception for signage.
Violations & Fines
Displaying a sign or any other advertising for a home occupation, whether a yard sign, window sign, or advertised vehicle at the property, is a violation of Sec. 17.225.050(C). The director of community development can revoke the home occupation's approval unless the sign is removed and the violation corrected within five days of written notice. Continued noncompliance can also jeopardize the business license required under subsection J, and any revocation decision may be appealed to the planning commission under Chapter 17.30.
