Septic inspection in Ottawa County: what to know
The evaluation rates a system acceptable in conformance, acceptable in substantial conformance, unacceptable or undetermined, and it does not approve or grandfather the system. The seller must give the buyer the complete results at closing, and failing to do so is a violation that can bring a civil citation or a misdemeanor appearance ticket. A sale with no evaluation adds a $250 charge to the fee, and a preliminary report that allows closing is $138.
Expect processing to take up to three or four weeks, according to the program flyer. The fee is $347 for sewage only and $461 for sewage and water, effective Oct 1, 2026, and a rush adds $347. The code says a report is valid for 12 months and the flyer says six, so ask the county which applies to your closing date.

- A routine inspection on the one-to-three-year cycle EPA suggests.
- A buyer's inspection with a closing date weeks away (check your county's sale rule first).

- Ask the county health department for your permit and as-built drawing.
- Clear the lids and note the tank size and last pumping date.
- Ask whether the visit includes pumping, the filter cleaning and a written report.
- Ask your county if it registers or certifies the inspector.

| Septic tank servicer wage, Michigan mean | $24.85 an hour | What Michigan septic tank servicers are paid (BLS, May 2025, statewide), not what you are charged. |
| Routine septic maintenance, pumping and inspection (U.S. EPA) | $250 to $500 every three to five years | EPA's national figure for maintenance fees, undated. It is not a Michigan price. |

How we estimate costs: the Estimated range row is a model, not a quote. It takes one published national range for this job (a cost guide from a third-party site that we have not verified and do not cite) and multiplies it by Michigan's septic tank servicer median wage ratio to the US (1.00, BLS 2025 data). No permit or evaluation fee is added: the county rows are shown as the schedules print them. The wage and fee rows are what workers are paid and what a county charges, and neither is a price you will be quoted. We have not collected Michigan septic quotes, and one company's published pumping price is not a range. Your tank, soil and site move a real quote outside any range, so get written quotes.
