SecureSpace Expands Seattle Footprint

SecureSpace Self Storage has opened SecureSpace Tukwila, a 53,185-square-foot facility in Tukwila, Wash.

InSite, which operates the SecureSpace Self Storage brand, acquired the 625-unit asset last month for $14.7 million, or roughly $200 per square foot, according to Yardi Matrix information. The property is also subject to a 10-year, $4.2 million loan, which TIAA originated in July 2020, the same source shows.

Located at 5950 Southcenter Blvd., the facility is just off interstates 5 and 405, some 12 miles southeast of downtown Seattle. SecureSpace Tukwila is one of the 11 self storage facilities available within a 3-mile radius, offering residents 6.7 rentable square feet per capita.

Completed in 2002, the five-story, Class A building features climate-controlled units, ranging between 25 and 300 square feet. Amenities include video surveillance, contactless renting, on-site manager, carts and dollies, as well as logged, seven-day access. The property is currently going through cosmetic enhancements, including improved security features through AI.

Weaker demand in Seattle

SecureSpace’s footprint includes assets located in key urban markets across the nation. The firm now owns a total of 15 self storage facilities in the Washington state, according to its website. Other properties in the metro area nearby the Tukwila location include SecureSpace SeaTac and SecureSpace Seattle Beacon Hill.

Despite limited inventory, weak demand pressured rates, which fell by as much as 2.5 percent or lower year-over-year in several metros across the U.S., according to the latest Yardi Matrix report. Seattle had one of the lowest rent performance nationwide as of February 2026, with Houston, Tampa and Orlando also in the red zone, reflecting some broader self storage market trends.
