How the michigan time of transfer evaluation process works
Michigan has no statewide rule, but several county health departments and townships require the private well and septic system to be evaluated before a property is sold. The written results go to the buyer, and failing systems must be corrected or the correction assured.
- Check whether the property is on a private well or septic system. Homes on public water and sewer are not affected.
- Apply to the local health department, or hire an evaluator it has certified. Some townships only accept the health department itself.
- Pump the septic tank if the rule requires it. Some codes require pumping within the last 2 or 5 years.
- Give the written evaluation to the buyer before closing. If the system fails, agree on who will repair it and when.
| Item | Typical range |
|---|---|
| Septic and well evaluation | $300 to $700 |
| Septic tank pumping | $300 to $600 |
| Drain field replacement | $8,000 to $25,000 or more |
