Why does DLI review plumbing plans for public and commercial buildings?
The Minnesota Plumbing Code requires that plans for all plumbing projects that serve the public must be reviewed and approved by DLI. The purpose of plan review is to check whether proposed projects will comply with the Minnesota Plumbing Code. If they do not, corrections can be made to the plan rather than to an actual plumbing system, saving time and expense. Go to top.
