Rural Benton County is farm and rangeland, so backyard hens and livestock are broadly allowed on appropriately zoned land, and Washington's Right to Farm Act shields established agricultural operations. Tri-Cities lots have tighter limits, and roosters can draw noise complaints.
RCW 7.48.305
Agricultural activities conducted on farmland and forest practices, if consistent with good agricultural and forest practices and established prior to surrounding nonagricultural and nonforestry activities, are presumed to be reasonable and shall not be found to constitute a nuisance unless the activity or practice has a substantial adverse effect on public health and safety.
Benton County and its cities require dogs to be leashed or controlled in public, with licensing and rabies shots. Under RCW 16.08.040 an owner is strictly liable when their dog bites someone lawfully in a public or private place.
RCW 16.08.040
The owner of any dog which shall bite any person while such person is in or on a public place or lawfully in or on a private place including the property of the owner of such dog, shall be liable for such damages as may be suffered by the person bitten, regardless of the former viciousness of such dog or the owner's knowledge of such viciousness.
Washington lets cities and counties pass breed-specific rules, but since 2020 RCW 16.08.110 requires any such rule to exempt dogs that pass a canine good citizen test. Benton County and the Tri-Cities rely mainly on behavior-based dangerous-dog law rather than breed bans.
RCW 16.08.110
Dogs that pass the American kennel club canine good citizen test or a reasonably equivalent canine behavioral test are exempt from breed-based regulations for a period of at least two years
Beekeeping is welcome across rural Benton County, and its irrigated farmland and wine-country bloom support strong colonies. Anyone keeping hives must register yearly with the state under RCW 15.60.021; the Tri-Cities may add hive limits and setbacks.
RCW 15.60.021
Each person owning one or more hives with bees, brokers renting hives, and apiarists resident in other states who operate hives in Washington shall register with the director by April 1st each year.
Washington bans keeping dangerous wild animals such as big cats, bears, wolves, primates, and venomous snakes as pets under RCW 16.30. Benton County enforces that state law, and the Tri-Cities may bar additional exotics.
RCW 16.30.030
A person shall not own, possess, keep, harbor, bring into the state, or have custody or control of a potentially dangerous wild animal.... A person shall not breed a potentially dangerous wild animal.
