The City of Bellevue has approved a major land use update that will transform the Wilburton area into a dense, mixed-use neighborhood designed to support life science research and development. Once known mainly for auto dealerships, the 300-acre district is being repositioned as a hub for labs, offices, and housing next to new light rail stations and the Eastrail multi-use trail.
The updated land use code gives life science developers new flexibility to meet the specialized needs of research facilities. Buildings with life science uses can extend rooftop equipment up to 45 feet above standard height limits, compared to 30 feet for general uses.
Most buildings in Wilburton are capped at about 30,000 square feet per floor, but labs and medical projects are now exempt from that restriction, allowing larger and more efficient layouts to support laboratories, GMP facilities, and specialized equipment.
To further encourage investment, development fees for life science or medical office projects will be cut in half for projects that begin before June 1, 2028, under Bellevue’s Commercial Catalyst Program. Across the Wilburton district, life science is now treated as an allowed use with tailored standards designed to support new projects.
Bellevue is already home to more than 3,800 life science jobs, a number that has grown 17 percent since 2019 and is projected to grow another 16 percent by 2029. The city also has a strong healthcare presence, with major providers like Overlake Medical Center, Kaiser Permanente, UW Medicine Eastside Specialty Center, and Seattle Children’s. Together with nearby research anchors such as the University of Washington and Fred Hutchinson Cancer Center, the city is well-positioned to expand its role in the industry.
By combining flexible building standards with near-term fee relief, Bellevue’s plan is designed to attract developers and companies seeking specialized lab space and faster project delivery. With a growing workforce, improved transit access, and a strong regional research ecosystem, Wilburton is being positioned as Bellevue’s next hub for innovation and life science growth.
