CBRE: Large blocks of office space lacking in many major U.S. cities

by Brianna Crandall — February 15, 2016—The improving economy and corresponding increase in office demand — along with new construction activity that has been slow to commence compared with previous cycles — has resulted in a diminishing number of available large blocks of office space in many markets across the United States, creating challenges for occupiers seeking large footprints, according to a new report from global property advisor CBRE Group.

While construction activity has begun to increase recently, new supply will not necessarily spell relief in all markets, the report indicates.

Downtown office markets

Among downtown markets in the third quarter (Q3) of 2015, the fewest total available large blocks (defined as 100,000 square feet or more of contiguous space) in existing and under-construction buildings were in Philadelphia (6), San Francisco (7) and Midtown South Manhattan (10).

For tenants requiring a large block in an existing building, there were only four options in San Francisco and five options in Seattle and Philadelphia — the lowest numbers among both downtown and suburban markets. However, with 2.6 million sq. ft. of large-block space in buildings under construction, Seattle can expect some relief from its current supply shortage.

While many constrained downtown office markets have new projects under construction, heavy pre-leasing activity means that the increased supply is often not enough to meet demand from large space users, notes CBRE. In San Francisco, nearly all of the space slated to come on line over the next 12 months is pre-leased, while in Chicago, over the next six months, the number of large, available blocks is expected to decrease due to rapid tech expansion and the in-migration of tenants from the suburbs and other states.

In Atlanta, there is just one large block under construction, according to the report. Active development markets like Seattle, Boston, Downtown Manhattan and Midtown Manhattan will likely see the number of available blocks tick up as new supply comes online. Meanwhile, Washington, DC, is expected to see its number of large blocks increase amid law firm and government downsizing and the movement of federal government tenants into GSA-owned space.

Andrea Cross, Americas head of office research, CBRE, pointed out:

Despite the improving economy and dearth of large, available blocks of space, rent levels do not justify new construction in many markets — particularly given rising development costs — which has limited the options for tenants requiring large footprints.

Suburban office markets

In the suburban markets, Denver and Orange County offer the fewest options for large blocks in existing buildings (12 and 16, respectively), and have very few blocks under construction as well. Those two markets, along with Boston and Chicago, have the smallest amount of square footage in large blocks as a percentage of the existing inventory.

CBRE suburban graph

CBRE determined the 10 largest suburban markets, by inventory.

The Washington, DC, suburban markets have the highest combined number of available large blocks, with 72 in Northern Virginia and 26 in Suburban Maryland; federal government downsizing and caution among contractors and other private sector companies that are reliant on federal funding have caused these markets to soften in recent years.

Among suburban markets, Houston also had a large number of available large blocks (89), reflecting weakness in the energy industry as well as increased sublease availability and ongoing new construction.

Available large-block space as a percentage of inventory was highest in New Jersey (9.7%), as the market has a large amount of outmoded corporate campus and other suburban space, some of which is being repositioned into walkable, mixed-use projects that are preferable to many of today’s employees.
