Selling a house on septic

Selling in Pierce County takes a Report of System Status from the Tacoma-Pierce County Health Department; selling in Kitsap County takes a Property Conveyance Inspection from Kitsap Public Health.

Revised November 4, 2026

How the Pierce County report works

The seller starts it, and a certified septic company does the first step. The department's page says the report begins with that company's operation and maintenance inspection and tank pumping, and that the finished report is valid for six months. In an April 14, 2026 bulletin, the department told applicants to apply as soon as the property is under contract, then submit the inspection report.

Pumping follows a published rule. A March 20, 2025 bulletin says the local Environmental Health Code requires pumping all septic and pump tanks for property sale inspections, with none needed if combined solids are 1 inch or less.

The April 2026 bulletin lists the report fee at $460 for 2026 and $240 for an additional report on one property, in a passage about mobile home parks with multiple systems. Ask the department what a single house pays.

When the inspection finds a problem

The sale can still go ahead under a conditional report. The department's page describes a 90-day version for cases where deficiencies remain and the buyer assumes responsibility to fix them within 90 days of sale. Read that as a real cost moved to the buyer, and settle who pays before signing.

The department gave a reason for its caution in an August 8, 2024 bulletin: it estimated that 500 to 700 systems had failed within two years of an approved report over the previous 10 years. An approved report is a snapshot, so it does not promise the system's future. That same bulletin paused a stress test for gravity systems at sale. We could not confirm the current position, so ask.

If you sell without one

The department follows up. An October 2, 2025 bulletin says it contacts all owners who sold without a report or an approved exemption and requires them to submit one, and that an exemption request form exists. Ask whether your sale qualifies before closing, not after it. New owners also get a letter three months after a sale with their inspection frequency and next date, so a buyer will hear about the system either way.

How the Kitsap inspection works

The Health District does this one itself. Its page says it gathers permit and service records, inspects the site and issues an evaluation letter, typically within seven business days. Ask what the letter means for your closing date.

We could not open Kitsap's pages directly, so treat these details as a search summary and confirm them at 360-728-2235.

Wells at sale time

A well brings its own paperwork. The Department of Health says that in most counties the county or lender may require the seller of a home with a private well to provide water-sampling results. Kitsap's page says Water Status Report applications should be filed 30 days before transfer, that one- and two-party wells and Group B systems need one, and that Group A systems are exempt. The state's private well testing schedule tells you which results to gather.

What a buyer should ask for

Ask for the paper itself rather than a summary of it. If you are unsure the house is on septic at all, check sewer or septic records first. For the system's upkeep after closing, see septic care on the peninsulas. For a home on a slope or waterfront, the sheet for the Gig Harbor Peninsula or South Kitsap lists who to call.

Sellers, buyers and agents should leave the lid alone. Nobody should open a tank, enter a pit or climb into one. This is our own safety advice, not a health department rule. The certified company does the opening. If sewage surfaces or backs up during a showing, stop using the drains. Keep people and pets well away.
