The U.S. office market is showing signs of renewed development activity, but this is not a return to the broad speculative construction cycle seen before the pandemic. Instead, new office projects are moving forward selectively, with premium tenants, significant preleasing, and prime locations determining which developments can secure financing and break ground.
According to CRE Daily, major companies are helping support a new generation of trophy office projects in markets including New York, Chicago, Miami, and Washington, D.C. At the same time, elevated vacancies, construction costs, and tighter lending standards continue to make speculative development difficult.
Preleasing Has Become Critical to New Development
One of the biggest changes in today’s office development environment is the importance of having tenants committed before construction begins.
Before the pandemic, developers could more readily pursue speculative office towers and secure tenants during construction. Today, lenders and investors are looking for greater certainty. CRE Daily reports that some lenders may require developers to have at least 50% of a building preleased before providing construction financing.
The broader construction market reflects that caution. CBRE reported that only 15.4 million square feet of U.S. office space was under construction in Q2 2026, an 87% decline from the Q2 2020 peak. Meanwhile, Colliers found that approximately 49% of the office space under construction or renovation across 13 leading U.S. markets was already preleased as of mid-2026.
This means a project backed by a large, creditworthy tenant is in a much stronger position to obtain financing and move forward.
Major Tenants Are Making New Towers Possible
Several recent projects demonstrate this trend.
In Chicago, Sidley Austin is expected to anchor a 45-story Fulton Market office tower, helping support what CRE Daily describes as the city’s first new ground-up office skyscraper in more than six years. In New York, American Express is advancing plans for an approximately 2 million-square-foot tower at 2 World Trade Center. Major tenants are also supporting new developments in Miami.
But not every proposed tower is succeeding. Miami’s One Brickell City Centre was scrapped after failing to secure sufficient tenant commitments, illustrating just how important preleasing has become to development feasibility.
The Flight to Quality Continues
The selective construction revival is another sign of the widening divide within the U.S. office market.
Companies continue to prioritize newer buildings, desirable locations, modern amenities, efficient layouts, and environments that can help attract employees back to the workplace. That demand is putting pressure on the limited supply of premium office space.
JLL reports that newer office buildings have become exceptionally scarce in many markets. Leasing at rents above $100 per square foot has reached record levels, while effective rents for new construction have increased by more than 20% on a rolling 12-month basis.
CRE Daily points to Sidley Austin’s Chicago commitment as an example: rents could exceed $115 per square foot, compared with previous market-leading rents closer to $70 per square foot.
A Two-Tier Office Market Is Emerging
While premium buildings are benefiting from stronger tenant demand, older office properties continue to face greater challenges.
CBRE reported that overall U.S. office vacancy declined to 18.3% in Q2 2026, while vacancy among prime properties was significantly lower at 12.3%. The gap between prime and non-prime vacancy is now at historically wide levels.
This creates a very different competitive environment depending on building quality.
New and recently renovated properties can increasingly compete on amenities, location, sustainability, workplace experience, and building quality, while older properties may need to rely more heavily on pricing, concessions, or substantial capital improvements to attract tenants.
For owners of aging office buildings, repositioning may become increasingly important. Buildings that cannot meet evolving tenant expectations could face longer vacancies and greater pressure on valuations.
What This Means for Office Tenants
For businesses considering a relocation, expansion, or lease renewal, the current environment creates both opportunities and challenges.
Overall office vacancy remains elevated in many markets, which can still provide tenants with negotiating leverage. But the story can be very different for the highest-quality office spaces. As companies compete for a relatively limited supply of premium buildings, tenants seeking the best locations and amenities may have fewer choices and face higher rents.
Companies with future space requirements should therefore begin evaluating the market well before their existing lease expires. Early planning can provide more time to compare renewal and relocation options, understand upcoming developments, and potentially secure space in a new project before availability tightens.
What It Means for Denver
The national trend also carries implications for the Denver office market.
Rather than assuming high overall vacancy means every office building offers the same opportunities, Denver businesses should evaluate the market at the building and submarket level. The national flight to quality demonstrates that premium buildings can perform very differently from older commodity office inventory, even within the same city.
For tenants, this makes workplace strategy increasingly important. Location, building amenities, accessibility, employee experience, lease economics, and future space needs should all be considered together when evaluating Denver office options.
For landlords, the message is equally important: quality matters more than ever. Investments in amenities, common areas, building systems, technology, sustainability, and tenant experience may help older properties remain competitive as companies continue gravitating toward higher-quality space.
The Bottom Line
The return of U.S. office construction does not signal a return to the old development model. Instead, the market is becoming more selective and increasingly divided by quality.
New towers are moving forward where developers can combine prime locations, creditworthy anchor tenants, substantial preleasing, and strong demand for premium space. At the same time, speculative construction remains limited, and aging buildings face increasing pressure to improve or reposition.
For tenants, landlords, investors, and developers, understanding this divide will be increasingly important as the office market continues its recovery.
