Licensing and permits in Minneapolis
Plumbing is licensed at both the state and city level in Minneapolis.

| Permit to discharge water to a storm drain or sanitary sewer, for example when pumping out a flooded space; sanitary sewer discharges may also need a Metropolitan Council Environmental Services permit | City of Minneapolis | City | Minneapolis: Temporary water discharge permit |
The City allows emergency repairs, such as a burst pipe, to start before a permit is issued, provided the permit application is filed by the next working business day. Each provider’s state and City licenses are checked before work is assigned.
Codes and local rules
Plumbing code. Minneapolis enforces the Minnesota Plumbing Code, Minnesota Rules, chapter 4714. DLI lists the 2020 Minnesota Plumbing Code as part of the current Minnesota State Building Code.
Backflow testing. The City requires regulated backflow assemblies (RBA) to be tested when first installed and at least once a year after that. The tester must hold a Minnesota backflow tester certification and submit results online through The Compliance Engine. A plumbing permit is needed when an assembly is installed, replaced, relocated or removed, and the contractor registers the change once the work is finished. The City lists a $500 non-compliance penalty per device, so test dates are tracked for every location.
Sewer responsibility. The City states that property owners must maintain their parts of the sanitary sewer pipes, vents and traps, and that owners should contact City Sewer Maintenance when a sewer backs up so the City can check whether the public sewer is the cause.
Preventive maintenance schedule for plumbing
Plumbing work is mostly on demand, but planned work keeps small problems from becoming closures. At Minneapolis sites, scheduled drain, water heater and grease interceptor service reduces backups during trading hours, and a fall check of exposed piping and shut-off valves reduces freeze damage. Planned visits also produce the test and pump-out records the City and the sewer authority ask to see.
| Task | Recommended frequency | Basis |
|---|---|---|
| Test regulated backflow assemblies and file results online | At installation and at least once a year | City of Minneapolis RBA testing requirements |
| Pump and clean grease interceptors | At the interval the sewer authority sets, and sooner once grease and solids reach 25 percent of the wetted depth | City of Bloomington, Indiana, Utilities procedure (25 percent rule) |
| Flush storage water heater tanks to remove sediment | At least once a year, or more often where the manufacturer instructs | Manufacturer instructions; Facility First program default, adjusted per site |
| Test the water heater temperature and pressure relief valve | At least once a year, or more often where the manufacturer instructs | Manufacturer instructions; Facility First program default, adjusted per site |
| Inspect exposed and perimeter piping, hose bibbs and heat tape before winter | Once a year, in the fall | Facility First program default, adjusted per site |
| Jet or snake high-use kitchen and restroom drain lines | Quarterly to twice a year, based on the location’s backup history | Facility First program default, adjusted per site |
| Inspect restroom fixtures, flush valves, supply stops and visible piping for leaks | Quarterly | Facility First program default, adjusted per site |
| Exercise main and fixture shut-off valves | Once a year | Facility First program default, adjusted per site |
The authority having jurisdiction, the equipment manufacturer and the property’s insurer can require more frequent service, and each location’s schedule is set in its program and recorded on every visit.
Seasonal and local conditions
- Frozen pipes. Long stretches below freezing make pipe-freeze prevention part of every Minneapolis program, as noted on the Minneapolis city page. Piping near exterior walls, loading docks and vestibules is checked in the fall, and a heating failure at a closed store is treated as a plumbing risk as well as an HVAC call.
- Spring thaw. Snowmelt and spring rain test floor drains, sump pumps and roof drain leaders. Backups in spring are checked against the public sewer before private lines are opened.
- Restaurant kitchens. Grease interceptors and kitchen lines are the most common source of drain calls at food service sites, so pump-out dates are scheduled and recorded.
- Older buildings. Downtown and older commercial buildings often have aging cast iron drain lines and shared risers, where landlord rules decide who repairs what.
Where Facility First works in Minneapolis
Facility First manages plumbing for locations across the Minneapolis area’s main retail and business districts, including Nicollet Mall in downtown Minneapolis, Mall of America in Bloomington, Southdale Center and Galleria in Edina, Ridgedale Center in Minnetonka and downtown Saint Paul. Sites include restaurants with grease interceptors, stores with staff restrooms and stockroom water heaters, and office suites in towers where the landlord controls risers and mains. Typical clients are retail and luxury retail, restaurants and corporate offices.
How plumbing requests are handled
- Request. The location or facilities team submits the request through the platform or by phone, with photos of the leak, fixture or backup.
- Triage. Facility First confirms priority, whether water must be shut off, landlord responsibility and any warranty.
- Dispatch. A vetted Minneapolis plumbing contractor holding the state and City licenses the work requires receives the work order and pulls any permit.
- Photo close-out. The plumber documents the cause, the repair and the condition after, with test results where a backflow assembly was tested.
- Verification and invoice. The work is checked against the request and invoiced in one format, with the record stored against the location.
Routine repairs proceed within the approval limits the client sets. Line replacement and larger work are quoted for approval first.
