No Space? No Problem. Large Block Availability Remains Along I-680 Corridor

Walnut Creek, CA. (November 4, 2015) — Newmark Cornish & Carey today announced that after Oakland, California’s recent absorption of several San Francisco-based tenants, the Downtown Oakland market joins the other supply-constrained markets of San Francisco, the Peninsula and Silicon Valley with rapidly escalating rental rates and few large block availabilities. However, the I-680 Corridor markets continue to offer numerous large block occupancy opportunities at cost-effective rates. In fact, there are currently several opportunities to lease more than 200,000-square-foot blocks of space in the North I-680 Corridor and Tri-Valley markets. In contrast, there are no 200,000-square-foot blocks of available space in Downtown Oakland, and San Francisco will not deliver any 200,000-square-foot blocks of space until mid-2017.

“In past cycles, as San Francisco became supply-constrained and tenants realized the burden of steeply escalating rental rates, companies sought less expensive, comparable space in the East Bay,” said Tom Fehr, a Newmark Cornish & Carey executive vice president and regional manager. “Uber’s market moving purchase of the Sears Building in September highlighted the recent flight to the Downtown Oakland market, and now the I-680 Corridor markets are poised to absorb the migration.”

The I-680 Corridor lies to the east of the Downtown Oakland market and encompasses the North I-680 cities of Concord, Pleasant Hill, Walnut Creek and Lafayette as well as the Tri-Valley cities of Danville, San Ramon, Dublin, Pleasanton and Livermore.

In San Francisco, the Class A vacancy rate is only 4.5 percent with an average asking rental rate of $5.81-per-square-foot-per-month fully serviced. The third quarter ended with tenant demand at 6.3 million square feet with as many tenants having requirements greater than 50,000 square feet as there were contiguous blocks of space that size available in both existing and under-construction projects. The Downtown Oakland market closed the third quarter with a Class A vacancy rate of 6.91 percent and an average asking rental rate of $3.47-per-square-foot-per-month fully serviced, and up to $4-per-square-foot-per-month fully serviced for prime vacant space. In contrast, the North I-680 Corridor market third quarter Class A vacancy rate was 16 percent, with asking rental rates ranging from $1.90 to $4-per-square-foot-per-month fully serviced. The Tri-Valley market closed the third quarter with a Class A vacancy rate of 18.66 percent and an average asking rental rate of $2.75-per-square-foot-per-month fully serviced.

Large block availabilities exceeding 50,000 square feet located along the I-680 Corridor markets include:


  • Swift Plaza – Newmark Cornish & Carey’s Breck Lutz and Alex Grell are marketing a full building opportunity consisting of approximately 185,000 square feet at 1755 Grant Street in Concord, California. At 1655 Grant Street, they are marketing approximately 98,000 square feet for lease.

Walnut Creek

  • Corporate Plaza – Newmark Cornish & Carey’s Tom Fehr and Alex Grell are marketing 51,000 square feet for lease at 575 Lennon Lane in Walnut Creek, California.

  • Bishop Ranch – Sunset Development Company, the owner of the eight million-square-foot business park, is nearing completion of major upgrades at 2600 Camino Ramon — the 1.86 million-square-foot building with multiple occupancy opportunities of 100,000 square feet and greater.


  • East Bay Center – Located at One Sybase Drive, the world-class campus has two 203,000-square-foot buildings available for lease after SAP vacates the campus in early 2017.


  • Rosewood Commons – Swift Real Estate Partners’ one million-square-foot campus has large block availabilities in two of the five buildings at the property.
  • Centerpointe – Formerly Safeway’s Corporate Headquarters, the 201,000-square-foot single tenant building is currently available for lease at 5918 Stoneridge Mall Road.
  • Sycamore Plaza – Newmark Cornish & Carey’s Jeff Morgenstern and Dan Watson are marketing 83,000 square feet of space at 6701 Koll Center Parkway in Bernal Corporate Park’s 99-acre, 1.2-million-square-foot master-planned business park.

“In addition to cost-effective occupancy opportunities for corporations, the Interstate 680 corridor offers employees affordable housing, highly-rated educational institutions, low crime rates and numerous regional parks and outdoor recreational areas – it is an incredible place to live,” continued Mr. Fehr. “I firmly believe history will repeat itself and the I-680 corridor will experience an influx of tenant migration soon.”
