Orange County had 37 hotels with 6,705 rooms under construction or in planning at the end of 2015, a report by Irvine-based Atlas Hospitality Group Inc. said.

The hotel consultancy and brokerage said those numbers break out as 12 hotels with 2,461 rooms under construction locally and another 4,234 rooms at 25 properties in planning.

Last year three hotels with 606 rooms opened—slightly below 2014’s four hotels with 699 rooms—Atlas said.

The largest hotel under construction at year-end—the Great Wolf Lodge in Garden Grove with 603 rooms—opened today.

The building and planning mirror-statewide numbers that show nearly 600 hotels with 90,000 rooms under construction or in planning.

“California is experiencing a hotel development boom, which will continue for at least the next 2-3 years,” said Atlas President Alan Reay.

Orange County projects under construction or in planning are 6% and 7% of the state’s totals, respectively.
