Providence Health & Services is packing up its headquarters and heading to Renton, locking in a roughly 260,000-square-foot lease at the Longacres office campus that is being billed as the largest new office deal in greater Seattle so far this year. The health system will consolidate several administrative operations into the Glacier and Baker buildings on the former Boeing site and is planning to shift its headquarters to the campus in 2027.
As reported by CoStar on April 21, 2026, the lease puts Providence into space previously occupied by Kaiser Permanente at Boeing’s former Longacres campus in Renton and marks the region’s biggest new office commitment so far this year, specifically tied to the Glacier and Baker buildings.
The deal in numbers
Newmark’s Q1 2026 Seattle office market report pegs the Providence commitment at about 259,570 square feet across six floors, labeling it the quarter’s largest Puget Sound office transaction and noting that the space had been used by Kaiser Permanente. The same Newmark analysis points to the Providence deal as a material contributor to the region’s positive absorption in the office market for the quarter.
