Among the new hospitality names checking in to Washington this year: The Trump International Hotel Washington, D.C.; the Pod D.C., and the MGM National Harbor.

They are among 14 new hotels scheduled to open in the region in 2016, adding more than 2,200 rooms to the local lineup. An additional 16 hotels are slated to open next year, up from 11 openings in 2015, according to data from Lodging Econometrics, a research firm based in Portsmouth, N.H.

The flurry in hotel openings comes seven years after the country suffered the worst recession in decades. The economic downturn, followed by a slowdown in government spending and tighter policies on employee travel, put the brakes on a number of large-scale hotel projects. Many were scrapped altogether.

Now, a number of hotel companies — including Hilton Worldwide, Kimpton Hotels and Marriott International are racing to build new properties, from a hotel full of tiny rooms at the Pod D.C. in Chinatown to luxurious, 6,300-square-foot suites at the Trump International.

“Development is near record levels,” said Stephen P. Joyce, president and chief executive of Choice Hotels in Rockville, which plans to open 375 more hotels in the United States this year. “The economy’s positive, employment is good, financing is available — it’s just a very positive time in the lodging cycle.”

In all, the Washington area has 688 hotels with 110,240 rooms. An additional 85 hotels, accounting for more than 14,000 rooms, are in the works, according to Lodging Econometrics.

Among the brands aggressively expanding in the region are McLean-based Hilton, which plans to open 22 properties in the region by 2018, including the luxury Conrad by Hilton at City­Center DC. Most of its planned hotels, however, are limited-service, lower-priced brands, such as Hilton Garden Inn and Homewood Suites by Hilton.

“We’re going through a building boom, if you will,” said Bill Fortier, senior vice president of development Hilton Worldwide. “As long as the U.S. economy continues to sputter along as it is, even if it’s just 1 or 2 percent growth, that’s enough to keep us adding new supply in certain markets.”

Nationally, the number of hotels starting construction this year is about 40 percent higher than it was last year, according to Bjorn Hanson, a professor at New York University’s Preston Robert Tisch Center for Hospitality and Tourism.

In all, 102,352 additional hotel rooms are expected to open in the United States this year, a 25 percent jump from the 81,589 rooms that hit the market last year, according to Lodging Econometrics. That translates to a 2 percent increase in the overall supply of rooms nationwide.

Some say the industry may be surging too fast. Demand for hotel rooms is projected to grow at a rate of about 2 percent this year, compared with 2.9 percent last year and 4.2 percent the year before.

“The concern for many analysts and hotel executives is that supply is accelerating at the same time demand growth is slowing,” Hanson said. “It’s kind of a troubling mix.”

Some hotel executives are beginning to sound the alarm.

“We are in or approaching a downturn,” Michael D. Barnello, president and chief executive of LaSalle Hotel Properties, a real-estate investment trust based in Bethesda, said in a call with Wall Street analysts in April. “While we cannot be certain whether the supply-demand dynamic will remain at a balance for the rest of the year, the data we have today has kept us cautious.”

Nationally, revenue-per-available-room, a closely watched industry metric, has grown at a slower rate for six consecutive quarters. Demand growth, meanwhile, has slowed for five straight quarters, according to data from Smith Travel Research.

During a call with Wall Street analysts this month, Arne M. Sorenson, chief executive of Marriott International, said the company expects the U.S. economy to bump along as the year progresses, zigzagging as individual markets respond to their own unique challenges.

“Houston — weak because of the weakness in the oil patch,” Sorenson said, according to a transcript of his remarks. “ New York — weak primarily because of supply growth but also maybe a bit because of the strength of the U.S. dollar and its impact on international rivals. Miami — weak probably mostly because of the weakness in Brazil, one of the great source markets for Miami and to some extent maybe growth in luxury supply. San Francisco — very strong reflection of the strong health of the U.S. digital economy. And of course, L.A. — also quite strong.”

“When we roll all these anecdotes together, the view about these markets, what we see is a collection of short stories but not a common theme, let alone the same author,” Sorenson concluded.

The Washington area, however, may be insulated — at least for now. Analysts say a number of the region’s new hotels are poised to benefit from an influx of travel after this year’s presidential election. Inaugural festivities, combined with the excitement of a new administration, are likely to draw large groups of travelers hoping to meet with new lawmakers and lobbyists.

“The timing of those openings is fairly fortuitous for Washington,” said David Loeb, a lodging analyst with the firm Robert W. Baird & Co.

An uptick in large conferences is also expected to keep area hotel rooms full next year. The District has already confirmed 21 citywide conventions for 2017, up from the 15 it is hosting this year.

The Watergate Hotel, which is reopening this month after a four-year renovation, will add 336 rooms to the District. It is not being counted as part of the 14 new hotels expected to open this year, since technically it is not “new.” The Kimpton Glover Park, which is opening in June, and Mason & Rook Hotel, which opened in Logan Circle in February, are also not part of that count because they are renovated properties.

“D.C. is looking to be a better-positioned market than it’s been in a long time,” Loeb said. But, he predicted, the hotel industry nationally is in store for a pullback sometime next year if the economy continues to sputter.

“It’s hard to tell: Are we going to have a soft landing or a harder landing, deeper downturn?” Loeb said. “It’s hard to see beyond 2017.”
