Washington (AP) The cost of renovations at a downtown cessellier hotel for a $250,000 renovation to its basement has more than tripled in the past six months, according to a document reviewed by The Washington Post.

The building at 1501 14th St. SE, built in 1926, is one of several in Washington’s historic district, which is home to more than 500 hotels and other businesses, including the C.I.O. headquarters and the Washington Monument.

The basement, the most expensive section of the building, cost more than half of what it had cost when it opened in 1926.

Since February, the cost has doubled, to more that $180,000.

And that figure includes the cost of the roof, the roofing materials and plumbing.

Cessellius, a real estate developer, declined to comment on the report but said the building was still under construction and had a lease until July.

It’s not clear when the building will be completed.

The Washington Metropolitan Area Transit Authority, which owns the area’s Metro stations, said the renovation is on track and will be finished by the end of the year.

The agency did not provide details on how much money has been spent on renovations.CESsellius did not immediately respond to a request for comment.

The C.E.O.’s contract with the Metropolitan Washington Airports Authority was canceled after a fire in December killed one person and damaged several buildings in the area.

The fire, blamed on a defective air conditioner, shut down the airport for about three weeks and left a trail of damage.
