Mower County Plumbing Permit Requirements
Mower County, Minnesota, handles building permits for properties located in unincorporated areas. If your property is within an incorporated city, that city's building department is responsible for permits. For unincorporated areas, Mower County Environmental Services, Zoning, and Land Use is the permit authority. You can contact them at 507-437-9560, extension 9217 (Angie Lipelt) or 507-437-9490.
While Mower County requires zoning permits for the construction or placement of any structure to ensure compliance with local zoning ordinances, specific plumbing permit requirements are primarily governed by the state.
According to Minnesota state regulations, plumbing permits and plan reviews are generally required for the installation, addition, extension, alteration, or replacement of any plumbing system. This includes interior plumbing, building sewer and water service connections within property lines, and storm water drainage systems. Permits are required for work that meets the Minnesota State Plumbing Code and follows an approved plan.
Specific types of plumbing work that commonly require a permit include:
- Drainage, waste, and vent systems
- Plumbing fixture installations and replacements
- Water piping and gas piping installations or replacements
- Storm water systems
- Sumps, flammable waste, or grease interceptors
- Water heaters
- Backflow prevention devices
However, there are some exceptions where plumbing permits may not be required. These can include minor repairs or replacements of internal working components of existing fixtures, such as faucets or valves, provided the existing plumbing system is not altered.
For projects requiring plan review, detailed plans, specifications, and fees must be submitted. The Minnesota Department of Labor and Industry (DLI) must approve these plans before any installation can begin. Some cities have agreements with the DLI for plan review, but certain projects may still require state review.
Plumbing permits are typically issued to Minnesota-licensed plumbing contractors or homeowners who are performing the work themselves.
