Unincorporated Contra Costa County requires dogs to be leashed in public, with leashes capped at 6 feet. Dogs must be licensed by 4 months old with current rabies vaccination; at-large violations start around $100 plus impound fees.
Contra Costa County's animal rules (Ordinance Code Chapter 416) require dogs in unincorporated areas to be leashed whenever they are on public property or someone else's land without permission, with leashes limited to 6 feet. Licensing is mandatory once a dog reaches 4 months, and a current rabies vaccination is required to get the license. Contra Costa Animal Services operates shelters in Martinez and Pinole, where impounded dogs are taken. Letting a dog run at large brings a fine starting around $100 plus impound fees, so secure fencing pays for itself quickly.
