National accounting and advisory firm expands Los Angeles presence at iconic tower.
Baker Tilly Advisory Group has leased 16,565 square feet of office space at 11150 Santa Monica Blvd in Los Angeles, marking significant expansion for the national accounting and advisory firm in Southern California. The lease reflects strong market demand among professional services firms for premium office locations in major metropolitan markets.
Baker Tilly is currently the sixth largest CPA advisory firm in the United States and the ninth largest accounting network globally by revenue. The firm maintains a coast-to-coast presence with major regional offices in New York, Los Angeles, San Francisco, Chicago, Boston, and London. Baker Tilly combines advisory, tax, and assurance services across its network of more than 43,000 professionals operating from 700 offices in 143 territories with combined global revenues of $5.6 billion.
Baker Tilly Advisory Group LP encompasses the firm’s advisory, tax, and consulting services divisions. The firm provides a broad range of professional services including internal controls and compliance consulting, forensic accounting, valuation services, IT consulting, business restructuring, and comprehensive tax advisory across local, state, and federal jurisdictions.
The Century City lease comes as Baker Tilly pursues an aggressive growth strategy. In April 2025, the firm announced a transformational merger with Moss Adams, a transaction valued at approximately $7 billion. Upon close, Moss Adams and Baker Tilly’s audit business will combine as Baker Tilly US, LLP, while the firms’ business advisory, tax, and other services will combine under Baker Tilly Advisory Group, LP.
Baker Tilly’s expansion at 2121 Avenue of the Stars coincides with Irvine Company’s 2025 leasing performance. The landlord executed leases for 8.7 million square feet across its six-market portfolio, finishing the year nearly 90 percent leased. This occupancy rate surpasses the national office vacancy rate of 22.2 percent reported in JLL’s Q4 2025 U.S. Office Market Dynamics report.
“In 2025, the office market continued to see demand for amenity-rich, well-located workplaces that offer an elevated experience, bring teams together and drive growth and productivity,” said Roger DeWames, president of Irvine Company Office Properties. Professional services firms, including accounting and advisory operations, have demonstrated strong appetite for well-positioned, amenity-rich office environments that facilitate client meetings and staff collaboration.
Baker Tilly’s Los Angeles presence has historically served as a significant hub for the firm’s West Coast operations. The Century City location provides proximity to major entertainment, media, and financial services clients that represent key markets for accounting and advisory firms. The firm’s expertise in real estate accounting, entertainment industry taxation, and financial consulting aligns well with Los Angeles’s diverse business community.
The accounting and advisory services sector has remained active in commercial real estate leasing throughout 2025. Firms like Baker Tilly recognize that premium office locations continue to drive client confidence, facilitate talent recruitment, and support the collaborative work environments that complex advisory projects require.
Renewals accounted for more than 5 million square feet of Irvine Company’s 2025 leasing activity, indicating sustained demand from existing tenants. Baker Tilly’s expansion at the Avenue of the Stars adds to a broad tenant roster that spans multiple professional services sectors.
Irvine Company’s Flex+ program leased nearly 2 million square feet during 2025, reflecting evolving workplace needs among professional services firms. This flexible workspace offering complements traditional long-term lease arrangements, providing clients options that align with diverse business models.
The 34-story tower at 2121 Avenue of the Stars remains one of Los Angeles’s most prominent office addresses, attracting major professional services firms across accounting, law, financial advisory, and related sectors. The building’s central location and comprehensive amenities support the operational requirements of national firms with significant client-facing responsibilities.
Baker Tilly’s investment in Century City space reflects the firm’s commitment to maintaining strong regional presences while executing its national growth strategy. The pending merger with Moss Adams positions the combined entity to serve an even broader client base across audit, tax, and advisory services. The Los Angeles presence serves as a critical component of this expanded national platform.
Professional services firms continue to view premium office real estate as integral to their competitive positioning. Baker Tilly Advisory Group’s expansion at one of Century City’s most recognized addresses underscores the ongoing importance of location, facilities, and institutional presence in the professional services real estate market.
