Denver CBD Office Market Approaches Stabilization as Elevated Vacancy Forces a Reset

Downtown Vacancy Remains Exceptionally High, but Deterioration Is Slowing

The Denver CBD office market remains one of the most distressed major downtown office districts in the country, although recent leasing indicators suggest that conditions are beginning to stabilize. Vacancy varies by provider and geographic definition. CBRE reported 38.6% total vacancy for Downtown Denver in the second quarter of 2026, while CoStar reported 32.3% for the traditional CBD, 24.3% for LoDo, and 24.1% for Platte River as of September 2026. Accordingly, Denver’s CBD can reasonably be described as having one of the highest, and by some measures the highest, office vacancy rates among major U.S. downtown markets.

The distinction is important because “CBD,” “Downtown,” and the broader central office market are not defined consistently. Combining the three CoStar submarkets identified as CBD, LoDo, and Platte River produces approximately 44.7 million SF of inventory and an aggregated vacancy rate near 29.4%. The combined market recorded roughly flat absorption over the past year, with positive demand in Platte River largely offsetting losses in the CBD and LoDo. That result is weak in absolute terms, but it represents an improvement from the more severe occupancy contraction experienced earlier in the office downturn.

Flight to Quality Is Redistributing Demand Rather Than Expanding It

Tenant activity remains highly selective. Government agencies, law firms, professional-service companies, and energy users have completed notable downtown transactions, while newer and highly amenitized properties continue capturing a disproportionate share of leasing. Tenants increasingly favor walkability, transit access, ready-to-occupy suites, modern building systems, and financially capable ownership that can fund substantial improvements and concessions.

This activity should not be confused with a broad-based expansion in office demand. Much of the leasing represents relocations, consolidations, and upgrades from less competitive buildings. Platte River recorded approximately 112,000 SF of positive annual absorption, while LoDo posted negative absorption of about 36,800 SF and the traditional CBD posted negative absorption of approximately 67,300 SF. The result is an increasingly bifurcated market in which successful properties can gain tenants even while overall downtown occupancy remains largely unchanged.

Stable Asking Rents Conceal Aggressive Concessions and Lower Effective Income

Asking rents have remained surprisingly stable given the depth of the vacancy problem. Reported annual rent growth was approximately 0.3% in each of the three central submarkets. Asking rents averaged $36.38/SF in the traditional CBD, $40.58/SF in LoDo, and $45.14/SF in Platte River. The higher Platte River rent reflects its concentration of newer, amenitized inventory rather than stronger overall occupancy.

Effective rental economics remain under pressure. CBD landlords are using free rent, large tenant-improvement allowances, turnkey suites, and other incentives to compete for a limited tenant pool. Approximately 600,000 SF of CBD sublease space remains available, with sublease offerings marketed at roughly a $13/SF discount to direct space. For valuation purposes, stable face rents should not be interpreted as evidence of stable net operating income. Lease-up periods, concessions, capital expenditures, free rent, and tenant-credit risk remain central underwriting considerations.
 
The Construction Halt Helps, but Recovery Requires Less Obsolete Inventory

The near-total absence of construction is the clearest support for downtown’s long-term outlook. No office space is under construction in the traditional CBD or LoDo, and only 120,000 SF is underway in Platte River. The completion of 1900 Lawrence in 2024 and Steel House in 2025 effectively marked the end of the most recent central-area development cycle. With elevated vacancy, high construction costs, lender caution, and existing buildings trading below replacement cost, another speculative CBD tower appears unlikely in the foreseeable future.

However, the absence of new construction will not resolve the market’s structural imbalance by itself. A meaningful portion of downtown’s vacant inventory consists of older buildings that may no longer satisfy contemporary tenant requirements. CBRE has indicated that approximately 9% of downtown office inventory is being considered for conversion. If a meaningful share is removed from competitive inventory through conversion, demolition, adaptive reuse, or occupancy by nontraditional users, the effective supply-demand balance could improve considerably without requiring a return to pre-pandemic office utilization.

Distressed Sales Are Resetting Values and Reopening Price Discovery

Investment activity is returning, but at sharply reduced values. The traditional CBD recorded approximately $166 million in trailing 12-month sales volume, compared with only $15.3 million in LoDo and $34.9 million in Platte River. Recent CBD transactions illustrate the scale of the valuation reset: Denver Place sold for approximately $51/SF, City Center traded near $40/SF, and the Denver Energy Center towers sold for less than $10/SF. By contrast, newer Platte River properties continued to attract materially higher pricing, reinforcing the widening valuation gap between modern competitive assets and obsolete commodity buildings.

The Outlook Is Stabilization Through Repositioning, Not Rapid Occupancy Growth

Downtown Denver appears to be moving from accelerated contraction toward gradual stabilization. Slowing move-outs, selective leasing, no meaningful new construction, and increased investor interest at reset values are constructive signs. Nevertheless, vacancy remains too high to support a rapid recovery in effective rents or broad property appreciation.

The indicators to monitor are net absorption, sublease availability, conversion activity, tenant-improvement costs, lease commencements in recently completed buildings, and the performance gap between competitive and obsolete assets. For owners, lenders, and appraisers, the central question is increasingly not when all vacant space will be reoccupied, but how much of the current inventory remains economically viable as office space.

KEY MARKET TAKEAWAY:

Denver’s CBD office market is showing early signs of stabilization, but a durable recovery will likely require obsolete inventory to be converted or removed, not merely stronger leasing demand.
