The volume of U.S. hotel rooms under construction decreased year over year for a 15th consecutive month, according to CoStar’s March 2026 data.
U.S. Hotel Pipeline
March 2026 (percentage change from March 2025)
- In construction: 136,990 rooms (-5.4 percent)
- Final Planning: 247,728 rooms (-9.3 percent)
- Planning: 333,467 rooms (-7.3 percent)
“Despite a continued decrease in the number of rooms in construction, there are just 10 less hotels in that phase than in March 2025,” Isaac Collazo, STR’s senior director of analytics said in a statement. “We are also seeing a shift in movement through the pipeline compared to last year, with more hotels advancing from earlier stages into construction. Development is still moving forward, albeit at a lower volume.”
Chain Scale Segments (percent of existing supply, in-construction room count)
March 2026 (percentage change from March 2025)
- Luxury (4.5 percent / 8,039 rooms)
- Upper Upscale (2.0 percent / 13,932 rooms)
- Upscale (3.3 percent / 31,204 rooms)
- Upper Midscale (3.3 percent / 40,179 rooms)
- Midscale (2.6 percent / 13,897 rooms)
- Economy (0.7 percent / 4,398 rooms)
“The luxury segment stands to see the largest percentage increase in supply (+4.5 percent) based on current construction,” said Collazo. “Going purely by number of rooms, the select-service segments remain at the top of the list by a wide margin.”
