Denver Office Vacancies Hit Record Highs, Defying Tech Boom Hopes

Denver's downtown office vacancy rate rocketed to 38.9% in the first quarter of 2026, an all-time high driven by a geographic and quality divide, according to CBRE data. Upper downtown's traditional central business district exceeds 40% vacancy, peaking at 46.4% in spots, while lower downtown hovers just above 20%, buoyed by the 2014 Union Station redevelopment that funneled billions into the transit-oriented neighborhood.[2] Citywide, the metro area leaves nearly 9 million square feet empty as hybrid work reshapes demand, with overall vacancies at 15.7% — topping the 2003 Great Recession peak of 15.5%.[1][5] RiNo's office vacancy stands at 49%, contrasting sharply with the central business district's 32%, as submarkets diverge amid 13.4 million square feet of vacant office and retail space downtown — equivalent to eight Empower Field stadiums.[3] Tech firms, a Denver staple, fuel the glut by downsizing footprints to slash costs without layoffs, dropping average lease sizes 45% from 2015 peaks; law firm Davis Graham & Stubbs exemplifies the trend toward efficient floor plans.[1] Comcast's recent exit of 33,000 square feet near Union Station underscores uneven recovery, with more square footage vacated than leased in LoDo last quarter.[2] Class A trophy towers hold steady at 29-32% vacancy since mid-2024, luring tenants from aging Class B and C buildings now at 44.4% vacant — some fully empty.[2][4] Sublease space has halved to 1.2 million square feet from pandemic highs, signaling stabilization, though new construction exceeding 1 million square feet since 2022 exacerbates the oversupply in Denver's 31.4 million-square-foot downtown inventory.[4] The Downtown Denver Development Authority deploys capital for office-to-residential conversions and distressed buys, while state policies curbing oil and gas relocations add pressure.[2][4] Front Range peers fare better: Colorado Springs at 7.8%, Fort Collins at 4.6%, Boulder at 18.9% and Denver Tech Center at 18.3%, leaving downtown Denver with the highest rate among major hubs.[3] Asking rents gap over $9 per square foot between direct and sublet space, with landlords slashing prices amid tenant leverage from record availabilities.[1]
