Summary
Imperial County flatly bans any sign at a home occupation site that identifies the service being offered, keeping the business visually undetectable from the street under the county's home occupation standards.

A.The home occupation shall be conducted solely by the occupant of the residence.B.The home occupation shall be conducted entirely within the primary or approved secondary structure.C.Not more than twenty percent (20%) of the gross floor area of any residence shall be used for such purpose.D.A detached accessory building may be used for a home occupation activity if approved by the planning director.E.No use shall require external alterations or involve construction features or the use of electrical or mechanical equipment that would change the fire rating of the structure or the structural integrity of the structure.F.There shall be no outside storage of any kind relating to the home occupation.G.The home occupation shall be a business that can and shall be conducted by appointment only.H.The home occupation shall not require the services of commercial freight deliveries other than normal postal type services.I.No home occupations shall create noise, dust, vibrations, smells, smoke, glare, electrical interference, fire hazard, or any other hazards or nuisance to any greater or frequent extent than that usually experienced by the average residential occupancy.J.There shall be no sales of products or merchandise on the premises.K.There shall be no sign permitted on the site indicating the service provided.

Full Breakdown
Imperial County Code § 90404.03(K) states there 'shall be no sign permitted on the site indicating the service provided' for any home occupation. This sits alongside the chapter's broader test in § 90404.00 that a home occupation must be run so the average neighbor would not be aware of its existence: signage, like on-site sales and outdoor storage, is treated as incompatible with that residential-character standard.
Violations & Fines
Posting a sign advertising the home business, even a small one at the curb or driveway, violates § 90404.03(K) and can trigger permit revocation under § 90404.09.
