Before inspection: build the property file

  • Search Livingston County’s current and archived Environmental Health records using the address or parcel ID.
  • Request the permit, approved design or as-built drawing, installation date, bedroom capacity, and inspection history when available.
  • Ask the seller for pumping, maintenance, alarm, repair, and replacement records.
  • Confirm whether additions, finished bedrooms, a pool, garage, pole barn, or driveway changed the site layout.
  • Locate the operating field and reserved replacement area; do not assume the greenest part of the yard is the correct location.

What a meaningful inspection should address

EPA guidance describes a typical inspection as more than a quick look at the tank. It may review permits and maintenance history; inspect tank levels, leakage, backup staining, structural condition, baffles, filters, pipes, pumps, controls, and the distribution box; and evaluate the drainfield for standing water or unequal drainage.

Ask for a written report distinguishing observed facts from limitations and recommendations. If parts could not be located or inspected, the report should say so. Clarify whether pumping is included and necessary for the chosen inspection method.

Questions buyers should ask

  • What system type and permitted capacity serve the home?
  • How old are the tank, field, pumps, and controls?
  • When was the tank last pumped, and what condition was documented?
  • Has sewage ever backed up, surfaced, or triggered an alarm?
  • Is the replacement area intact and free of structures or paving?
  • Does an alternative system carry an operating permit or maintenance obligation?
  • Would planned remodeling require county review?

How sellers can reduce surprises

Gather the county file and service history early, make tank lids accessible without unsafe excavation, and disclose known problems through the appropriate real-estate process. Avoid cosmetic attempts to hide wet ground or odors. If a repair is proposed, obtain required county guidance and retain final approval.

When a report identifies a concern, negotiations can address further evaluation, repair before closing, a credit, escrow, or a price adjustment. The right structure depends on the contract, lender, insurer, and local requirements; use qualified real-estate and legal professionals for transaction advice.

A recent pump-out is maintenance evidence. It is not, by itself, proof that the tank, distribution system, and drainfield are sound.
