The bill introduces a new section to chapter 72.09 RCW that establishes restrictions on the housing assignments of inmates in correctional facilities based on their biological sex. Specifically, it prohibits an inmate from being assigned to share a room or cell with another person of a different biological sex if the inmate has a documented history of sexual or physical violence against individuals of the same biological sex as the other inmate.

The bill defines "a history of sexual or physical violence" as encompassing one or more current charges or prior convictions for sex offenses, violent offenses, or domestic violence, as outlined in RCW 9.94A.030. This legislative measure aims to enhance the safety and security of inmates by preventing potentially dangerous situations arising from inappropriate housing assignments.
