Summary
Rancho Cucamonga protects historic farmland through its Agricultural Overlay under Development Code Section 17.38.050, letting eligible parcels keep orchards, field crops, tasting rooms, and farm stands. New agricultural uses on land with no farming history instead go through Section 17.32.030 review, not the overlay.
B. Applicability. Only those properties which have historically housed agricultural production associated with the agricultural heritage of the city may be eligible for the Agricultural Overlay. Any proposal for new agricultural uses proposed on property which had not previously been utilized for agricultural purposes shall be reviewed pursuant to Development Code section 17.32.030 (Agricultural uses permitted or permitted with a minor use permit)... D. Permit requirements, and public hearing and public notice required. An application for an Agricultural Overlay shall be filed with the planning department in a manner prescribed by the planning director with the required fee as established by city council resolution. Approval of the Agricultural Overlay shall be the responsibility of the city council, upon recommendation of the Planning Commission and the process for review shall be the same as a zoning map amendment pursuant to Development Code section 17.22.040.

Full Breakdown
050(B). 030 (Agricultural uses permitted or permitted with a minor use permit). Within the overlay, allowed uses include orchards, field crops, truck gardening, and flower gardening; farm stands and agricultural product processing including cooking classes; tasting rooms and wineries; and up to three dwelling units per parcel of ten acres or more for an owner, manager, or on-site employee. 050. on weekdays including Saturday, and at any time Sunday or a national holiday, and noise at the property line is capped at 65 dBA. Farm stands are limited to 500 square feet of structure or display area, must sell only on-site-grown product, and must sit at least 50 feet from every property line.
Parcels over ten acres inside the overlay can also pursue a Williamson Act contract for a property-tax reduction in exchange for keeping the land in agricultural use, and approved overlay parcels may participate in the city's Transfer of Development Rights program to sever and sell development rights to builders elsewhere in the city.
Violations & Fines
Operating outside the overlay's permitted use list, running a farm stand larger than 500 square feet, or generating noise above 65 dBA at the property line or during the restricted overnight/Sunday/holiday hours violates Section 17.38.050(E) and is enforced as a development code violation through the planning department, subject to the city's standard code enforcement and abatement process for zoning noncompliance.
