Mountain View FAQ
Where are SCC's agricultural zones located?
Mostly in unincorporated South County: Coyote Valley north of Morgan Hill, the San Martin growing belt, the Gilroy area, and hillside ranchlands above Saratoga and Los Gatos. Cities have their own zoning maps, generally without ag districts.
What does Williamson Act enrollment require?
Landowners sign 10-year minimum contracts restricting parcels to agriculture in exchange for reduced property-tax assessments. Cancellation requires Board of Supervisors approval and triggers a fee up to 12.5% of unrestricted market value.
San Jose FAQ
Can I farm commercially in San Jose?
Only in the A zone, mostly in Coyote Valley and parts of Almaden Valley. Other zones allow limited urban agriculture and community gardens but not commercial-scale row-crop farming.
Can I get a tax break for an urban farm in San Jose?
Possibly. Under California AB-551, parcels under five acres dedicated to agriculture for at least five years may qualify for reduced property tax assessment in designated urban-ag incentive zones.
