Selling your home
To sell your home you don’t need a county inspection of your septic system. By state law you must properly disclose to the buyer information about the septic system. A well-informed buyer will want a thorough inspection. Many lenders require a compliance inspection before they issue a mortgage.
Systems the county inspects
- New septic systems
- Repairs on current septic systems
- Current septic systems under investigation because of a complaint
- The county doesn’t inspect current septic systems unless they’re under repair or under investigation
Certificates of compliance
- Current systems: valid for 3 years (unless an imminent health threat)
- New systems: valid for 5 years (unless an imminent health threat)
Notice of noncompliance
- 3 years to upgrade (unless an imminent health threat)
An imminent health threat means sewage surfaces to the ground, backs into the home, or reaches surface or groundwater.
Subject to either septic permit approval or compliance inspection:
- All building permits for new commercial or new residential structures
- Any permits for bedroom(s) additions, any additions or remodeling of commercial facilities where water use will increase
- Any permits within designated shoreland areas
- Any permits within designated wellhead protection areas
Older septic systems
Septic systems built before January 23, 1996 are compliant if they meet two criteria:
- Two feet of soil separation is provided
- It is not classified as an imminent health threat. This means sewage surfaces to the ground, backs into the home, or reaches surface or groundwater.
This provision excludes:
- Shoreland areas
- Food, beverage, and lodging facilities
- Wellhead protection areas
- New construction
Septic systems must have a general setback of 50 feet from a wetland.
Warrantied systems are not allowed. See warrantied systems under MN Statutes Chapter 115.55.
