From The Washington Post:
The Secret Service has vacated its command post inside Trump Tower in Manhattan following a dispute between the government and President Trump’s company over the terms of a lease for the space, according to two people familiar with the discussions.
Previously, the Secret Service had stationed its command post — which houses supervisors and backup agents on standby in case of an emergency — in a Trump Tower unit one floor below the president’s apartment.
...
“After much consideration, it was mutually determined that it would be more cost effective and logistically practical for the Secret Service to lease space elsewhere,” spokeswoman Amanda Miller wrote in an email to The Washington Post.

According to the article, the Secret Service command post has relocated to a trailer parked on the street outside the building. Presumably they worked out a better deal with the City of New York.
Remember back in 2016, Trump suddenly doubled what he was charging his own campaign to lease office space inside his tower. He pretty clearly just tried the same scam on the Secret Service, who aren’t having it.
