To ensure the quality of workmanship on buildings and structures within the City of Saint Paul, and to safeguard public health and welfare, certificates of competency are required of skilled workers in specific building trades. The state Department of Labor and Industry (DLI) has a search tool that allows you to see if a person or company has a current license, bond, certificate or registration issued by DLI. The License and Registration Lookup portal is found here

Different classes of certificates are specified under each type of work to recognize levels of expertise. For details about certificate requirements, please see the Saint Paul Legislative Code, Chapter 370 here.
