Summary

Thurston County does not ban owning venomous reptiles, large constrictor snakes or primates, but it heavily regulates them. County Code Section 9.10.040(J) requires owners of constrictor-type reptiles over eight feet, venomous reptiles and primates to register annually with Animal Services, and Section 9.10.056 requires a humane, secure facility and immediate reporting of any escape.

These county ordinances apply to unincorporated areas of Thurston County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Full Breakdown

030 defines an 'exotic animal' broadly as any animal such as, but not limited to, venomous or constrictor type reptiles or primates, folding those species into the county's general pet-animal licensing and control scheme rather than a separate ban. 040(J) then imposes the county's core control measure: owners of constrictor-type reptiles longer than eight feet, venomous reptiles, and primates must annually register each animal with Thurston County Animal Services on a form the department provides. Registration is not optional and is not a one-time step; it must be renewed every year alongside, but separate from, any dog or cat license the household also carries.

Failure to register any of these animals is charged as a misdemeanor. 056 sets a housing standard: the owner must maintain a humane and secure facility for every constrictor over eight feet and for all venomous reptiles, and must report any escape of a venomous or constrictor-type reptile to Animal Services immediately, not after the fact. 056, stacking on top of any registration violation. 10, is the enforcing agency for both duties, and a citation can be issued by any officer commissioned by the Board of County Commissioners to enforce the chapter.

Violations & Fines

Keeping an unregistered constrictor over eight feet, a venomous reptile or a primate without annual Animal Services registration is a misdemeanor under Section 9.10.040(J). Failing to house the animal in a humane, secure facility, or failing to report its escape immediately, is a separate misdemeanor under Section 9.10.056. Both charges can be issued at once, and both are prosecuted like any other Chapter 9.10 misdemeanor in Thurston County District Court.

Frequently Asked Questions

Can I legally own a large snake or venomous reptile in Thurston County?
Yes, but you must register it. Section 9.10.040(J) requires anyone keeping a constrictor-type reptile over eight feet, a venomous reptile, or a primate to register the animal annually with Thurston County Animal Services on the department's form. There is no outright ban, but skipping registration is a misdemeanor.
What housing does Thurston County require for a pet python or venomous snake?
Section 9.10.056 requires a humane and secure facility for any constrictor-type reptile over eight feet and for all venomous reptiles. If the animal escapes, the owner must report it to Animal Services immediately; failing to maintain secure housing or failing to report an escape is a misdemeanor.
Does Thurston County classify pet monkeys as exotic animals?
Yes. Section 9.10.030 defines an 'exotic animal' to include primates, so owners of pet monkeys or other primates fall under the same annual registration duty in Section 9.10.040(J) that applies to owners of large constrictors and venomous reptiles kept in the county.
