Summary
El Cajon confines commercial agriculture to the O-S, RS-40, and RS-20 zones, and only for commercial horticulture; every other commercial agricultural activity is barred citywide, while private orchards, gardens, and greenhouses are allowed as an accessory use to any residential property.
Commercial horticulture may be conducted in the O-S, RS-40, and RS-20 zones subject to the provisions of this chapter. No other commercial agricultural activities are permitted in any zone. Non-commercial agriculture such as private orchards, gardens, and greenhouses shall be permitted ancillary to any permitted residential use... Agricultural products may be sold at roadside stands in the O-S, RS-40, and RS-20 zones with approval of an administrative zoning permit and provided that the product is grown or produced on the same property.

Full Breakdown
El Cajon Municipal Code Sec. 205 (Agriculture and Animals), draws a sharp line between commercial and non-commercial agriculture. " That means commercial row-crop farming, livestock operations run as a business, or similar for-profit agriculture outside horticulture has no zone in El Cajon where it is allowed by right or by permit. Non-commercial agriculture is treated far more permissively: "private orchards, gardens, and greenhouses shall be permitted ancillary to any permitted residential use," so a homeowner anywhere in the city may grow food or ornamental plants for personal use without a separate agricultural zoning designation.
205's requirements. The code also allows roadside sale of agricultural products, but narrowly: sales are limited to the O-S, RS-40, and RS-20 zones, require approval of an administrative zoning permit, and the product sold must be grown or produced on that same property, meaning a stand cannot resell produce sourced elsewhere. This structure functions as El Cajon's agricultural zoning framework rather than a right-to-farm nuisance shield; the city has not codified a separate right-to-farm nuisance-protection statute for these permitted uses.
Violations & Fines
Chapter 17.205 is a Title 17 zoning chapter, so unpermitted commercial agricultural activity outside the O-S, RS-40, or RS-20 zones, or a roadside stand operating without the required administrative zoning permit, is a zoning code violation subject to the city's standard zoning enforcement and administrative citation process rather than a chapter-specific penalty schedule.
