Imperial County, CA Home Business: Zoning Restrictions (2026)

Title 9, Division 4, Chapter 4 (Sections 90404.00 et seq.) governs home occupations in the unincorporated area, defining one as a residential accessory use located and operated so that the average neighbor under normal circumstances would not be aware of its existence. Section 90404.01 lists permitted single-person home occupations such as an artist or photographic studio, one-person professional office (architect, engineer, consultant, accountant, notary), author or composer, dressmaker or tailor, home crafts, telephone-answering service, key/locksmith service, and a cottage food operation. The minimum standards in Section 90404.03 require that the occupation be conducted solely by the occupant of the residence; entirely within the primary or approved secondary structure; in no more than twenty percent (20%) of the home's gross floor area; with no outside storage; by appointment only; with no commercial freight deliveries beyond normal postal service; with no products or merchandise sold on the premises; and with no noise, dust, vibration, smell, smoke, glare, electrical interference or other nuisance beyond what a normal residence produces. A detached accessory building may be used only if the Planning Director approves. Section 90404.02 prohibits certain uses outright as home occupations — including day care, school or preschool, auto/small-engine repair, barber/beauty shop, restaurant, gift shop, kennel, and medical or dental clinics.
