Kaiser Permanente says it will build a seven-story 615,000-square-foot hospital tower at its Sunnyside Medical Center campus in Clackamas, OR, with an opening date scheduled in 2029. Construction will begin in early 2026, with site-clearance work starting in late 2025. The current hospital building will remain in use until the new hospital tower is built and open on the east side of the Sunnyside Medical Center campus.
