Medical Pavilion I & II Benefits from Tightening Washington, D.C. Medical Office Market as National Outpatient Demand Accelerates
Medical Pavilion I & II at National Harbor offers a modern outpatient campus designed to meet evolving needs amid strong demand for healthcare space
NATIONAL HARBOR, MD / ACCESS Newswire / July 21, 2026 /Surging outpatient demand is tightening medical office markets across the country, as construction pipelines stall nationwide and federal policy accelerates the shift from inpatient care.
Washington, D.C. 's medical office market is leading that trend, according to new data from CoStar Group, with local vacancy running nearly 6.5 percentage points below the region 's traditional office market. The outlook for local class-A offerings, such as Medical Pavilion I & II at National Harbor, Md., has improved as well, with occupancy rates dipping for multi-story, multi-tenant dropping from 14 to 13.5 percent across the region.
National Demand Accelerates
National data shows that outpatient occupancy continues to climb, reaching 92.5 percent across the top 50 U.S. markets in the first quarter of 2026, with absorption up 71 percent year-over-year, according to a new Cushman & Wakefield Vital Signs report. JLL 's 2026 Medical Outpatient Building Perspective separately reported occupancy reaching a record 92.7 percent to close out 2025, driven by a near-universal drop-off in new construction pipelines with new medical office building construction starts representing just over 1 percent of total existing inventory.
At the same time, the Centers for Medicare & Medicaid Services are further accelerating the shift from inpatient to outpatient care. Consequently, hospital systems are being asked to expand capacity, modernize facilities, and support physician alignment, all while managing limited capital and strict regulatory oversight. Medical Pavilion I & II was purpose-built to support the continued expansion of outpatient healthcare services.
"What we 're seeing in Washington, D.C. is really a local reflection of a national story, " said Peter Papantoniou, Principal at Gittleson Zuppas Papantoniou Medical Realty, the leasing broker for Medical Pavilion I & II at National Harbor. "Outpatient demand is growing faster than the pipeline can keep up with, and that 's holding vacancy down and pushing rents up almost everywhere. "
"Our investment strategy has always been centered on creating long-term healthcare destinations rather than simply leasing office space, " said Malika Peltier, Managing Director at Rethink Healthcare Real Estate. "National Harbor offers providers the rare combination of modern medical facilities, strong health system partnerships, exceptional accessibility, and a growing patient population. Those fundamentals position the campus to benefit from the continued migration of care into outpatient settings for years to come. "
Washington, D.C. Metro MOB Market Heats Up
CoStar Group data shows medical office vacancy in the Washington, D.C. metro area held at 11.7 percent in the first quarter of 2026, with rent growth of 1.9 percent over the trailing 12 months, well ahead of the 0.2 percent growth rate for all D.C.-area office space. At the same time, large health systems are shifting away from small footprints, prioritizing multi-specialty clinics in the 40,000 to 60,000 square foot range to capture steady outpatient margins.
Medical Pavilion I & II at National Harbor is positioned squarely in that demand, offering Class-A outpatient space in one of the region 's most sought-after mixed-use settings. With limited new Class A medical office construction underway throughout the region, opportunities to secure large contiguous outpatient space are becoming increasingly scarce.
"Not all medical real estate is created equal, " Papantoniou said. "Medical Pavilion I & II gives practices the quality, visibility, and accessibility tenants are competing for right now. "
The waterfront destination includes more than 40 dining options, boutique shopping, MGM National Harbor, The Capital Wheel, hotels, and year-round events, all within a short walk of the medical offices. National Harbor 's I & II key amenities include:
Two Class-A Medical Office Buildings consisting of over 190,000 rentable square feet.
Co-located with luxury residential, retail, and office amenities immediately adjacent to major population growth.
Anchored by major health systems and capable of accommodating large institutional users.
One of the few large blocks of modern medical space available in Prince George 's County.
Immediately available, built-out medical office suites.
Ample structured parking, valet, and direct public transit access.
Located within National Harbor 's mixed-use district, the campus offers patients and employees walkable dining, hospitality, retail, structured parking, and regional transit access.
Despite broader economic uncertainty, the National Harbor district is set up with a steady pipeline of new economic stimuli, including the development of the East Coast 's first Sphere entertainment venue and a new $720 million mixed-use development plan, which will bring over 1,000 more market-rate multifamily units and 485 affordable senior apartments, as well as new retail and office spaces, further expanding the population base that Medical Pavilion I & II is positioned to support.
As healthcare providers continue expanding outpatient services throughout the Washington metropolitan area, Medical Pavilion I & II represents one of the region 's few opportunities to secure large-format Class A medical office space in a growing mixed-use healthcare destination.
