The Empire State Building is a working office tower, a major tourist destination, and one of New York City’s most important broadcast transmission sites. While it’s famous as an icon of the Manhattan skyline, the building earns its keep through nearly 2.8 million square feet of rentable office space spread across 76 commercial floors, two public observation decks that draw over 2.5 million visitors a year, and a broadcast antenna mast that transmits signals for dozens of TV and radio stations.
Commercial Office Space
The building’s primary function is the same one it was built for in 1931: office space. With 2,815,706 rentable square feet across 76 floors, it remains one of the largest single office buildings in New York City. The tenant roster reflects a mix of tech, media, and global brands. LinkedIn, Shutterstock, Booking Holdings, and the Swedish construction firm Skanska all have offices there. Centric Brands, a fashion company, signed a lease for over 212,000 square feet alone.
Empire State Realty Trust, the company that owns and operates the building, markets the space to companies that want a recognizable Midtown Manhattan address. The building’s location near Penn Station and major subway lines makes it practical for commuters, not just prestigious for letterheads.
Observation Decks and Tourism
Tourism is the building’s most visible public use. Two observation decks, on the 86th and 102nd floors, offer the two highest open-air vantage points in Manhattan. The 86th-floor deck sits at 1,050 feet. The 102nd-floor deck reaches 1,250 feet. More than 2.5 million people visit each year, making the observatories one of New York’s top paid attractions.
The experience extends beyond the views. The building redesigned its observatory entrance and exhibits in recent years, adding an immersive museum-style walkthrough on the way up that covers the building’s construction, history, and place in pop culture. Timed-entry tickets help manage crowd flow, and visitors can book sunrise or late-night time slots for less crowded conditions.
Broadcasting and Telecommunications
The antenna mast at the top of the Empire State Building has been one of the most important broadcast transmission points in the United States for decades. At least 22 stations have transmitted from the building simultaneously, including major New York television stations like WCBS, WNBC, WABC, WPIX, and WNEW, along with a cluster of FM radio stations.
A shared master FM antenna, mounted around the mooring mast near the 102nd-floor observation deck, carries signals for stations across the dial, including WNYC, WQXR, WBAI, and WOR-FM. The building’s height and central Manhattan location make it ideal for line-of-sight broadcasting across the metro area. Even after the construction of the One World Trade Center broadcast antenna, the Empire State Building continues to serve as a transmission site for multiple stations.
Events and Private Gatherings
Several spaces inside the building are available for private events. The Starbucks Reserve store on-site, for instance, offers bookable rooms for team-building sessions, group dinners, cocktail receptions, and corporate meetings. These aren’t generic conference rooms. The spaces are designed around coffee and cocktail tastings, positioning the building as a venue for experiential corporate events rather than standard office rentals. The building also hosts seasonal public events, including its famous annual lighting displays that change color for holidays, awareness campaigns, and cultural celebrations.
Energy Efficiency and Sustainability
A major retrofit completed over two years earned the Empire State Building LEED Gold certification, making it the tallest LEED-certified building in the United States at the time. The upgrades were projected to cut energy use by 38 percent. That overhaul included replacing all 6,514 windows with insulated glass units, upgrading heating and cooling systems, and installing a building-wide energy management system. For a structure built in 1931, hitting modern green building standards required rethinking nearly every major system without disrupting the tenants working inside.
The certification matters commercially, not just environmentally. Companies increasingly require LEED-certified office space to meet their own sustainability commitments, so the retrofit helps the building compete for tenants against newer towers that were designed with energy efficiency from the start.
How It All Fits Together
The Empire State Building works because it layers multiple revenue streams into a single structure. The lower floors handle retail and visitor traffic. The 76 office floors generate steady lease income from corporate tenants. The observation decks on floors 86 and 102 bring in tourism dollars. The antenna mast at the top earns broadcast licensing fees. Each use occupies a different zone of the building, so they coexist without competing for the same space. It’s not a museum or a monument. It’s an active, fully operational commercial building that happens to also be one of the most recognized structures on the planet.
