Dallas' hotel building boom shows no sign of a let up.

The Dallas-area had the second highest total of new hotel projects in the pipeline at midyear. Only New York City had more new hotels in the works.

Dallas has a total of 156 hotel projects with 18,908 rooms in the construction pipeline or planned in the second quarter, according to a new report by Lodging Econometrics, which tracks hotel construction.

New York City was first in the country with 169 hotel projects.

The lodging industry analyst said that Dallas currently has 47 new hotels with 6,350 rooms under construction. And another 73 hotels with 8,606 rooms are scheduled to start in the next 12 months.

"If all of the projects in the pipeline eventually come to fruition, this will increase the city's guest room supply by 21.3 percent," Lodging Economics said in the new report. "Dallas should continue its fast-paced growth.

"In the first half of the year, it led all markets for the most new hotel projects announced into the pipeline, with 27 projects and 3,195 rooms."

Most of the current construction in the Dallas area is located in Denton, Lewisville, McKinney, Plano and Frisco, according to the report.

The Dallas area will rank second in the nation for new hotel openings in 2018 with 33 projects and 3,813 rooms, according to Lodging Econometrics. And next year Dallas is forecast to be in third place national with 30 hotels opening with 3,224 rooms.

After New York City and Dallas, the other top U.S. hotel construction markets are Nashville with 43 projects, Houston with 40 projects and Atlanta with 28 projects.

"Historically, according to our hotel real estate intelligence, the New York City market has led the construction pipeline by projects since third quarter 2011," said J.P. Ford, Lodging Econometrics' senior vice president. "This has been followed by Houston.

"However, in Q1 2018, Dallas surpassed Houston to take the second spot in regards to hotel construction," Ford said. "We are expecting Dallas and Houston to continue to remain top markets, in terms of projects, in the United States for the next few years."
