When it comes to building maintenance, some of the most recognizable buildings in America—like the iconic Empire State Building—are among the country’s worst, according to an analysis by the nonprofit real estate site Real EstateTrac.

According to the report, more than half of the nation’s 50 tallest buildings are ranked in the “low maintenance” category.

The list, which includes skyscrapes like the 110-story Burj Khalifa in Dubai and the 210-story Trump Tower in New York City, is dominated by the likes of the Trump International Hotel in Washington, D.C., and the Trump Tower’s iconic red-brick facade.

“The number of times that a building is considered ‘low maintenance’ varies depending on the complexity of the building,” Real Estate Trac founder John P. Hodge told Newsweek.

“For example, a complex, multi-story structure like a Trump Tower could require maintenance every year.”

The report also revealed some of America’s most expensive skyscrapings, including the $2.8 billion Trump International Golf Club in West Palm Beach, Florida, and the $5.3 billion Trump National Golf Club and Spa in Jupiter, Florida.

The Trump Organization’s flagship hotel in Washington DC, the Four Seasons, was ranked second in maintenance.

“There’s nothing wrong with the hotel’s condition, but we would never recommend it to anyone,” the company said in a statement.
