Denver’s office sublease market is showing meaningful improvement, with downtown sublease availability dropping 29.1% year-over-year to approximately 1.4 million square feet as of Q2 2025. This signals that many companies have completed post-pandemic space rationalization, and quality sublease inventory is being absorbed by tenants seeking below-market rents and move-in-ready space. SVN Denver Commercial explores what declining Denver office sublease space availability means for tenants, landlords, and the broader office recovery heading into 2026.

Downtown Denver’s office vacancy rate hit 37.7% in Q3 2025 — the highest level since the 1980s oil bust — driven by remote work, tenant flight to quality submarkets, and public safety concerns. Not all of downtown is equally distressed: LoDo and Union Station hover near 20% vacancy while upper CBD towers reach 40–46%. SVN Denver Commercial breaks down the causes, the signs of stabilization, and what the data means for investors and tenants navigating the market today.

The RiNo office market has transformed Denver’s River North Art District from a former industrial corridor into a top destination for creative and technology tenants. With adaptive reuse buildings, mixed-use integration, and strong transit access via the 38th and Blake RTD station, RiNo offers a workspace character that traditional submarkets cannot replicate. SVN Denver Commercial tracks this emerging submarket for investors and tenants evaluating office opportunities in Denver.
