What is on the checklist
EGLE publishes the list it recommends owners follow every year: open and inspect all tanks, pump if the tank is more than one-third full of scum and sludge, clean the effluent filter, test the control panel alarm and pump, walk the drain field, check inspection ports for standing water and look for leaking fixtures. EPA says an average household system should be inspected at least every three years by a septic service professional, and systems with pumps or floats once a year. A county or an inspector sets the scope, so two reports on the same tank can differ.
What a septic inspection costs in Michigan, county by county
A routine inspection comes to $130 to $520 per inspection in our model, an estimate and not a quote, built from one published national range and Michigan's septic tank servicer wage ratio to the US (1.00). Some counties evaluate systems with their own staff, and the rows below show what they charge, with the schedule year in the note. Michigan has no statewide inspection fee, and private inspectors set their own prices.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $130 to $520 per inspection | Built from one national published range, adjusted by the Michigan septic tank servicer median wage ratio (1.00). No Michigan septic company published a range we could count. |
| 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. |
| Wayne County, health department evaluation | $358 | Fee schedule effective Jan 16, 2024. A $161 "transfer evaluation" is listed separately, and the schedule does not say who performs it. |
| Macomb County, property transfer evaluation | $384 | 2026 schedule; excludes pumping. |
| Ottawa County, real estate evaluation, sewage only | $347 | Fees effective Oct 1, 2026; sewage and water together $461. |
| Saginaw County, mortgage or performance evaluation, septic only | $440 | Fee schedule effective Oct 1, 2026. |
| St. Clair County, septic evaluation only | $225 | Fee schedule as of Oct 1, 2026. |
| Muskegon County, septic evaluation | $150 | 2026 schedule; the county describes evaluations as voluntary. |
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. Full method. Prices as of Oct 19, 2026.
Who may inspect in Michigan: no state license, some county lists
We found no statewide septic inspector or evaluator license in Michigan law. EGLE's advice is to ask your local health department for a list of professionals. Counties that run sale-inspection programs keep lists of their own: Macomb County registers evaluators for a $220 fee and publishes an annual list, Washtenaw County certifies inspectors who complete county training, and Ingham County publishes its certified point-of-sale inspectors. Wayne County says evaluators must register, per the county's page, so confirm it with the county. Grand Traverse County and Shiawassee County certify evaluators for their own transfer rules.
Senate Bill 771 of 2026 would require evaluators to register with EGLE, with a $180 application fee. As of Oct 19, 2026 it is awaiting third reading in the Senate, so it is not law.
When the health department does it, and what it adds
Some counties perform evaluations themselves. Saginaw County's evaluation requires the inspector to locate the tank, expose an inspection port and pump the tank at the time of evaluation, and for systems installed without a permit, generally before March 1975, all four drain field corners must be uncovered. Macomb's property-transfer evaluation excludes the pumping. The tank must be pumped with the evaluator on site, but not within 30 days before the evaluation; the evaluator can say who schedules it. Fees for these county evaluations are in the table below.
Pull the county file before the inspector arrives
EPA says the local permitting authority usually holds the permit and the as-built drawing. Practice varies by county. Marquette County offers a free online well and septic records search, Bay County publishes a public septic system map, Jackson County says well and septic records after 1972 should be on file, and Genesee County sells a records search for $5 an address and says not every property has records. The county rules tool shows what we have on file for your county.
When an inspection cannot wait
- Sewage backing up into the house or surfacing in the yard: call your local health department.
- An alarm sounding, or a wet, foul-smelling patch over the tank or field.
- 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).
Before you book
- 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.
Permits and licensing for inspections
A pumper hired during the inspection needs EGLE septage licenses under Part 117. At sale, some counties require an evaluation: see septic inspection at sale.
A tool for this job
County septic rules lookup
Michigan has no statewide septic code, so your county or district health department sets the permit, sale-inspection and installer rules. Pick your county to see what the county publishes, with the source and the date we checked. Nothing is shown for a county until it has been researched, and where a rule is unconfirmed the tool says so.
Open the toolQuestions people ask
What does septic inspection consist of?
EGLE lists tank inspection, scum and sludge measurement, filter cleaning, alarm and pump testing and a drain field walk. It also checks inspection ports for standing water and looks for leaking fixtures.
How are septic systems inspected?
By a visual check of the tank, filter, controls and drain field, with the tank usually opened and measured. Some counties require the tank to be pumped during the evaluation, as Saginaw County does.
How much does a septic inspection cost in Michigan?
Our estimate for a routine inspection is $130 to $520 per inspection, a model and not a quote. Counties that do evaluations publish fees, from $150 in Muskegon County to $440 in Saginaw County for septic only. Private evaluators set their own.
Are septic tank locations public record?
We can cite no single statewide record: ask your county health department. EPA says it usually holds the permit and as-built drawing, and counties differ on how you request it.
How often does a 1000 gallon septic need to be pumped?
It depends on how many people use it: Oregon State gives 5.9 years for two people and 2.6 for four. That is an Oregon table, shorter with a garbage disposal. EGLE says pump when the tank is more than one-third full.
