Summary
Unincorporated Orange County's A1 General Agricultural District permits farming, ranching and crop sales as by-right uses on a 4-acre minimum site.
The purpose of the Agriculture and Open Space Districts is to promote the preservation and protection of resource areas including agricultural lands, cultural-historic resources, significant wildlife habitats, and biotic resources that shape the overall urban form of the County... The A1 "General Agricultural" District is established to provide for agriculture, outdoor recreational uses, and those low-intensity uses which have a predominately open space character.

Full Breakdown
The county's A1 "General Agricultural" District is set aside for agriculture, outdoor recreation and low-intensity open-space uses, and can also serve as a holding zone ahead of future urban development. Crop cultivation, agricultural processing and support services are principal permitted uses in A1 needing no discretionary permit, while apiaries, wineries, commercial equestrian stables and packing plants for agricultural products require a Site Development or Use Permit. Minimum building site area in A1 is 4 acres, with a 35-foot maximum building height and a 70-foot minimum site width. This zoning applies only in the unincorporated county; Anaheim, Santa Ana, Irvine and Orange County's other 30 cities set their own agricultural zoning.
Violations & Fines
Building without the required Site Development or Use Permit for a conditional agricultural use, or exceeding the A1 height and site-coverage limits, is a zoning violation enforceable by OC Community Resources / Code Enforcement, which can order correction or pursue nuisance abatement.
