Nevada has long been known for having one of the highest levels of contractor licensing, but the number of licenses in the state is dropping.
In a report published by the Nevada Government Accountability Office (NGAA), the number was up to just five in February, and by the end of March, the state had issued just one license.
A recent NGA survey found that in 2017, only two contractors had the required license.
In the state of New York, it was four in 2016, and in California, it is only one.
The report, which looked at the number and type of licenses issued by the state, showed that while a contractor license has been used by about 3,400 businesses since it was created in 1881, the number has fallen to just four in 2017.
The New York State Department of Labor and Industry, which regulates the construction industry, said in a statement that it was looking into the issue.
The NGA study said that between 2009 and 2016, there were more than 14,000 licensed contractors, a number that has steadily declined over the years.
The number of licensed contractors has remained fairly stable since 2009, according to the NGA report.
The majority of contractors were based in Nevada, but there were also companies based in Colorado, Florida, Georgia, Kansas, Louisiana, Massachusetts, Montana, Nevada, New Jersey, North Carolina, Ohio, Pennsylvania, Texas, Utah, Virginia and Washington.
