Livestock: Martinez vs San Ramon

Livestock (horses, cattle, goats, sheep, pigs) is prohibited on standard residential lots in Martinez and restricted to parcels with agricultural zoning or minimum lot sizes typically over one acre. Miniature goats and potbellied pigs may be allowed as pets with setback requirements on larger lots. Rural parcels in unincorporated Contra Costa County near Martinez follow less restrictive county standards.

Livestock is prohibited on standard residential lots in San Ramon. The city's suburban master-planned zoning does not include agricultural districts, and lot sizes in Dougherty Valley, Bishop Ranch, and Canyon Lakes communities are too small for livestock. Limited exceptions exist for properties with agricultural zoning adjacent to open space preserves.
