Union Square commercial district
Union Square is best known as a retail and visitor district, but its upper floors and smaller commercial buildings also support professional, showroom and client-facing office users. It offers a busier hospitality and shopping context than a conventional office core. Businesses should distinguish the district’s public-facing setting from the quieter or more business-dense conditions found in the Financial District and Jackson Square.
