Who can perform work under a mason contractor license?
A mason contractor license authorizes mason work to be performed by the licensed business and its employees, working under the supervision of the business’s supervising mason.
“Employees” means individuals that the business treats as employees for purposes of unemployment insurance contributions, worker’s compensation, and income taxation. A mason contractor license does not authorize mason work to be performed by individuals who are paid by the licensed business as independent contractors.
If employees of another business will be performing mason work at a job site, that business must be licensed as a mason contractor and listed on the permit.
Are there different types of mason contractor licenses?
