JMB Realty Lands 157 KSF Lease Renewal, Expansion in Houston
An energy firm signed the agreement.

Long-term tenant Chord Energy has renewed and expanded its lease at JMB Realty’s 1001 Fannin in Houston. Partners Real Estate negotiated the lease on behalf of JMB.
Chord is renewing 130,300 square feet and expanding into an additional full floor of 27,090 square feet. Chord focuses on hydrocarbon exploration and hydraulic fracturing in North Dakota’s Williston Basin and has been a tenant in 1001 Fannin for nearly 20 years.
The 47-story LEED Gold-certified tower includes 1.3 million square feet of office space with eight corner offices per floor, 25,000 square feet of retail and amenity space, and a parking garage that covers a full city block and is connected to the building via tunnel.

Following a recent multimillion-dollar renovation, JMB is developing a new conference center with space for large corporate events, smaller conference rooms for tenant meetings and pre-function areas for gatherings.
Another energy-related firm, Black Stone Minerals, has been a tenant at 1001 Fannin for more than three decades. Black Stone Minerals renewed its lease of 55,082 square feet at the tower in May 2025.
Chip Colvill, a partner in Partners’ Houston office, and Brad Beasley, senior vice president, represented the landlord in the lease negotiations. Cushman & Wakefield Executive Managing Director Chad Beck represented Chord Energy.
Houston office update
Other Houston office activity came in late July, when The Wideman Co. acquired TotalEnergies Tower, a 35-story office building in downtown Houston, from Brookfield Properties. The 850,000-square-foot asset was developed in 1971.
The biggest lease in downtown Houston’s office market in the third quarter of 2026 was by an energy company. Marathon Petroleum signed a 56,749-square-foot renewal and expansion at 500 Dallas St., according to a report released last week by Savills.
The Central Business District’s availability is 28.9 percent, in comparison to the metro’s overall 26.2 percent, which was down by 60 basis points year-over-year, Savills reported.
