Hathaway Dinwiddie Construction Company has signed a full-floor lease at Union Bank Plaza in Downtown Los Angeles, relocating its offices to the 16th floor of the Class A tower at 445 South Figueroa. The lease covers 17,554 square feet and reflects the construction firm's decision to consolidate operations on a single floor within a modernized high-rise environment in the downtown business district.
Newmark arranged the lease on behalf of Hathaway Dinwiddie. Executive managing director David Kluth and associate director Mai Hu led the tenant representation team, guiding the construction company through site selection and lease negotiations for the full-floor premises. On the ownership side, CBRE professionals John Zanetos and Chris Penrose represented the landlord, providing advisory and leasing services for the tower.
Commenting on the move, Kluth described the relocation to 445 Figueroa as a meaningful next step for Hathaway Dinwiddie, noting the company's longstanding presence as a tenant in downtown Los Angeles. The upgraded and revitalizing condition of the property was highlighted as a key element of the firm's decision to shift into a full-floor configuration at Union Bank Plaza.
Union Bank Plaza, located at 445 South Figueroa Street, is a 40-story Class A office tower originally constructed in 1967. The property offers more than 700,000 square feet of office space, supported by a two-level retail center that provides on-site amenities for office users and visitors. The complex also includes a two-acre landscaped outdoor plaza, designed to enhance the campus feel of the project, along with ample parking to accommodate office and retail demand.
Beyond the new lease, Union Bank Plaza has also seen recent investment activity. In late 2024, the property traded for $80 million in a transaction in which Newmark represented both sides of the deal. Newmark advised the seller and also represented the buyer, Washington Capital Management, in the sale of the office tower. The combination of a significant institutional sale and subsequent full-floor leasing underscores ongoing engagement from both investors and occupiers at the asset.
Together, the 2024 ownership change and Hathaway Dinwiddie's full-floor lease illustrate continued capital and tenant interest in a large, established high-rise in Downtown Los Angeles. With professional representation on both the investment and leasing fronts, Union Bank Plaza continues to serve as a notable office location in the downtown market.
