Madera County Unincorporated, California Zoning Map

ARE-40 designates parcels in a zone where each parcel must be at least 40 acres in size, and the primary permitted use is agricultural production. Residential development is allowed but limited to one dwelling unit per parcel (typically a farmstead), with farm-worker housing subject to additional conditions. The purpose is to prevent rural subdivision that would fragment agricultural land and increase incompatible uses in farming areas. Investors treating ARE-40 land as a short-term development play will face significant rezoning hurdles, as the county actively resists changes to these large-lot agricultural designations.

Gunner Ranch and Gateway Village are master-planned communities in unincorporated Madera County with their own zoning districts (G-LDR, G-MDR, G-MUC, G-MC, G-OS and GV-C, GV-HC, GV-MU, GV-NC, GV-OS, GV-R) that define specific residential densities, commercial uses, and open-space allocations within the planned community footprints. Development within these zones follows the adopted specific plan documents rather than the standard county code. Buyers of parcels within these districts should obtain the specific plan and any recorded development agreements to understand phasing requirements and infrastructure financing obligations.

Industrial Heavy (IH) at 2,134 acres and Industrial Light (IL) at 2,778 acres are significant industrial nodes within unincorporated county territory, positioned near Highway 99 and key agricultural processing corridors. These zones serve crop processing, cold storage, food and beverage manufacturing, biomass energy, and agribusiness-related distribution. The county's rural setting means industrial projects often face CEQA review for traffic, air quality, and groundwater impacts, and project sponsors should engage early with county planning and air district staff on permit pathway.

Agricultural land protected under Williamson Act contracts - which cover substantial acreage in the county - cannot be converted to non-agricultural use until the contract is non-renewed and a 10-year notice period elapses. Even without a Williamson Act contract, rezoning ARE-designated land from large-lot agricultural to residential requires a General Plan amendment and environmental review, and the county's agricultural preservation policies create a high bar for approval. Developers should confirm contract status and applicable General Plan designations for any parcel before modeling residential conversion scenarios.

The ARF Agricultural Rural Foothill zone covers 42,134 acres in the Sierra Nevada foothills of Madera County and is designed for lower-intensity uses where terrain, water availability, and fire risk make intensive agriculture or dense residential development impractical. Permitted uses typically include grazing, timber, and rural residential development at large minimum parcel sizes. Foothill parcels within the ARF zone are subject to state fire-hazard severity zone requirements and may trigger CEQA analysis for fuel modification and access road standards on any new construction project.
