This number is higher than the average construction cost hikes nationwide, which were 2.5% in 2013 and 3% in 2014.
Hospital construction is the most expensive, at $800-$950 per sf. Five-star hotels follow at $700-$800 per sf, and university buildings at $600-$850 per sf.

President of the New York Building Congress Richard T. Anderson says that the annual 5% increase rate should be a cause for concern to the city, even though a considerable portion of the recent increase in costs is the product of forces beyond the city's control. He called for the industry and government to look for ways to reduce the cost of construction and eliminate regulations and red tape, according to GlobeSt.com.
