Local governments and the State of Minnesota require septic system certification inspections to be performed by a state-certified septic system inspectors. Things that trigger a mandatory inspection to ensure your septic system is up to code varies from county to county, but the most common is when a property is being sold or is in need of a permit for other construction. This is also a service we strongly urge anyone to complete, prior to closing, if you are purchasing a property that uses any type of septic system.  Hidden repair costs could easily be in the thousands, depending on its condition).  We can also perform an inspection if you have concerns about your septic system.
