Summary
A Whittier home-based business cannot put up any sign beyond what the zone already allows for that residential lot, under Whittier Municipal Code Section 18.10.020(C)(7): "There is no use of any sign not otherwise permitted in the zone in which the occupation is located." A home business advertising sign is simply not an available option in a residential zone.

Full Breakdown
" Residential zones in Whittier do not otherwise authorize commercial advertising signs, so in practice this condition bars a home occupation from posting any business sign, window sign, sandwich board or yard sign identifying the business to the public; the home is treated exactly like any other residence for sign purposes. This sits alongside the section's other limits, including a ban on structural alteration (condition 6) and the twenty-five percent floor-area cap (condition 4), all aimed at keeping a home business invisible from the street and indistinguishable from ordinary residential use of the property.
A resident who wants exterior identification, such as a small nameplate for a licensed contractor or therapist, has to fit within whatever the underlying residential zone otherwise allows for any dwelling, which for most Whittier residential zones is effectively nothing beyond an address number. Operating with an unauthorized sign puts the whole home-occupation approval at risk, not just the sign itself.
Violations & Fines
Posting a sign not otherwise permitted in a residential zone violates Section 18.10.020(C)(7) and can cost the business its accessory-use status entirely. As with the section's other conditions, this is not on the Section 1.08.015 infraction list, so Section 1.08.010's general penalty applies: up to a five-hundred-dollar fine or six months in jail.
