Overview
Monroe Correctional Complex, on 177th Avenue SE in Monroe, is a multi-unit state prison complex for men in Snohomish County, northeast of Seattle. WA DOC operates it as several distinct units at different custody levels:
- Washington State Reformatory unit — a medium-custody general-population unit.
- Twin Rivers Unit — houses sex-offense treatment programming.
- Sky River Treatment Center — residential mental-health care for men; formerly the Special Offender Unit.
- A minimum-security unit — minimum-custody housing.
- An Intensive Management Unit — restrictive housing, where visits are non-contact.
Because the complex spans minimum through maximum custody across separate units, a person’s housing assignment determines which unit’s rules and visiting arrangements apply.
