All permits for building projects are issued to either owner / builders or contractors, and those contractors require a current state license. Potential owner / builders should contact the Development Information Center prior to planning any major projects for information about whether your project meets the limitations placed upon owner / builder projects.

Before planning a project with a contractor, it is recommended that you check the license status of the potential contractor(s) at the State Licensing Board website
