Optimism Remains. SUBURBAN CHICAGO OFFICE Fourth Quarter Research & Forecast Report

Research & Forecast Report SUBURBAN CHICAGO OFFICE Fourth Quarter Optimism Remains Ronna Larsen Senior Research Manager Suburban Chicago The Chicago Suburban office market is awaiting occupancy of several large tenants in 2017 to overcome the negative absorption total witnessed in. Despite ending the year with negative absorption, 19 new lease transactions greater than 25,000 square feet occured in the Chicago suburban office market in compared to 17 transactions in. Many of these leases will commence in the first and second quarters of 2017. Trends The swift velocity of investment and user sales in the suburban office market continued in as 45 assets traded hands. Fourth quarter notable transactions included the Blackstone s 699,120-square-foot, three-building portfolio sale in Rosemont to Adventus Realty Services; TIAA-CREF s 264,162-square-foot sale in Oakbrook Terrace to Hamilton Partners; and Colony Realty Partners 232,152-square-foot sale to Helios Property Management, also in Oakbrook Terrace. Several investment properties were added to the market in, including five in the fourth quarter alone such as Schaumburg Corporate Center and Balmoral Business Campus. In addition, there are four assets currently under contract. While the number of large tenants in the market dissipated throughout, there continues to be a number of mid-sized tenants with potential to relocate. There are currently 66 tenants with needs ranging from 10,000 to 50,000 square feet that are actively seeking space in the suburban office market. Well-capitalized building owners in the suburbs continue to focus on tenant improvements and increased amenities such as structured parking, power to accommodate the modern tenant, employee wellness / fitness centers, food service, tenant lounges and conference centers and outdoor spaces to cater to the younger generation.

While conditions in the Oak Brook market improved, the Northwest market reported the highest increase in overall vacancy, rising to 24.5 percent from 22.4 percent at the end of. Vacancy in Class A properties also rose throughout, ending at 21.1 percent compared to 19.4 percent at the end of. However, as tenants such as Paylocity, Brunswick, Valent Biosciences, Vyaire Medical, and Combined Insurance begin moving into their new spaces, vacancy in the suburban office markets is expected to decrease throughout 2017. While overall sublease vacancy increased slightly, it remains low at 1.4 percent compared to 1.2 percent at the end of.

Absorption Overall net absorption ended at negative 845,165 square feet, compared to positive 1,029,499 square feet in the previous year. Larger tenant movement including Redbox, Banco Popular, Conagra and Zurich which moved into its build-to-suit headquarters were major contributors to the negative absorption. Large Blocks of Availability There are currently 45 properties in the suburban office market that can accommodate users 100,000 square feet and larger, while 35 of those properties are Class A. Large blocks of space in the O Hare and Oak Brook markets are difficult to find, however, the Northwest market offers the majority of options. Rents Average Class A asking rents increased in, rising to $28.69 per square foot gross, up from $28.40 per square foot gross at year-end. The average asking rent for all classes in suburban Chicago ended at $20.51 per square foot gross, up from s rate of $20.34 per square foot. Construction While there hasn t been any speculative construction delivered since 2010 and none is expected throughout 2017, build-to-suit activity is thriving within the suburban market, particularly in the Northwest sector. Projects there include Zurich North America s recently completed 735,000-squarefoot headquarters in Schaumburg; American Academy of Pediatrics 193,000-square-foot build-to-suit property in Itasca; and McShane Development Company / MetLife Real Estate Investors recently announced Huntington 90, a buildto-suit business park in Hoffman Estates. What To Expect in 2017 > > We will see a wider spread in performance between Class A and Class B properties. While true Class A properties with high-quality amenities will continue to drive the market in 2017, Class B properties will struggle. > > True Class A investment sales will continue throughout 2017, while investment sales of A- and Class B properties with fewer amenities will begin to taper off. > > A modest increase in absorption is expected throughout 2017.

Northwest Over the years, the Northwest suburban office market has been home to an array of industries, making it the most diverse market in the suburbs.

Vacancy The Northwest market retained the highest vacancy level in all of the suburban markets as it ended with 24.5 percent vacancy, up from 22.4 at year-end. Class A properties were the culprit for a majority of the rise in vacancy, ending the year at 23.4 percent compared to 20.68 percent at year-end. However, when larger tenants such as Paylocity and Swiss RE Management begin moving into their space, vacancy is expected to decline in 2017. Sublease vacancy remains low in the Northwest with 0.8 percent vacancy, up slightly from 0.7 percent at year-end. Absorption The Northwest market ended with negative 636,815 square feet of net absorption, compared to negative 170,525 square feet at year end of.

North Home to many large corporate occupiers, The North market has primarily attracted tenants for its low Lake County tax rate to the north and its proximity to Downtown Chicago to the south.
