A Tale of Two Recoveries
The commercial office market in the United States is experiencing a deeply uneven recovery. National office vacancy rates remain elevated at 19.6 percent, according to CBRE data from early 2025, but that headline figure masks dramatic variation between markets, building classes, and submarkets.
Sun Belt cities including Nashville, Austin, and Miami have seen vacancy rates decline steadily as population growth, corporate relocations, and a more favorable return-to-office culture drive demand. Meanwhile, traditional gateway markets like San Francisco, where vacancy rates exceed 30 percent in some submarkets, continue to struggle with oversupply and slow return-to-office adoption.
Class A Versus Everything Else
The flight to quality that began during the pandemic has only accelerated. Class A office buildings with modern amenities, efficient floor plates, and strong ESG credentials are experiencing vacancy rates five to eight percentage points below market averages. Many trophy properties in prime locations are effectively fully leased.
The picture for Class B and Class C buildings is far grimmer. These older properties face a structural demand problem that is unlikely to resolve without significant capital investment in renovations or conversion to alternative uses such as residential, life sciences, or mixed-use developments.
The Conversion Challenge
Office-to-residential conversions have emerged as the most discussed solution for obsolete commercial buildings, but the economics remain challenging. Floor plate depths, structural systems, plumbing infrastructure, and zoning requirements make many office buildings poor candidates for residential conversion.
Successful conversions typically involve older buildings with relatively narrow floor plates, located in neighborhoods with strong residential demand and supportive municipal policies. Several cities, including New York, Chicago, and Washington, D.C., have introduced tax incentives and streamlined permitting processes to encourage conversions.
What Tenants Want Now
Corporate tenants are leasing less space per employee but demanding higher quality. The typical office footprint per worker has shrunk from 200 square feet to approximately 150 square feet as companies design for hybrid work patterns. At the same time, tenants are willing to pay premium rents for buildings that offer collaborative spaces, wellness amenities, and flexible lease terms.
Investment Implications
For commercial real estate investors, the office sector demands a highly selective approach. Well-located, well-amenitized Class A assets in growing markets remain attractive. Older buildings in markets with weak demand fundamentals carry significant risk and may require repositioning strategies or outright write-downs. The era of treating office real estate as a homogeneous asset class is definitively over.
