A septic system deserves its own place on your homebuying checklist. Before closing on a Tacoma-area property, you need to know what serves the house, what condition it is in, and which responsibilities you will inherit.
For help arranging a septic inspection, call Septic Pros at 877-996-9191 with the property address and your transaction timeline. We will confirm the service scope and availability.
1. Confirm the property uses septic and get the records
Ask the seller for the system's record drawing, inspection reports, pumping receipts, and repair history. Tacoma-Pierce County Health Department provides links to its record-drawing and inspection-report tools.
Keep the records together under the property address and parcel number. Ask the inspector to explain anything that does not match what you see at the property. An old invoice is useful history, but it should not be your only evidence of the system's current condition.
Useful questions include:
- Where are the tanks, drainfield, and designated reserve area?
- What type of system serves the house?
- What does the approved design allow?
- Have repairs, additions, or changes been documented?
- Who has maintained the system, and when was it last serviced?
If you are planning an addition, rental space, or a change in occupancy, discuss it with the Health Department before assuming the existing system can support it.
2. Ask for the Report of System Status
Pierce County's sale process generally requires a Report of System Status, commonly called an RSS. TPCHD describes a process involving professional inspection and tank pumping, an application, and Health Department review and a property inspection. Approved exemptions may apply.
The department says its review goal is ten business days, which cannot be rushed or guaranteed. An issued RSS is valid for one year. Check the current RSS process directly with TPCHD.
For a buyer, the useful question is: “Can I review the issued report and any conditions before my decision deadline?” Confirm dates and any outstanding items with the seller, your agent, and the department. A pumping receipt and an issued RSS are different documents.
3. Review the findings with the inspector
Read the findings rather than relying on a verbal “it passed.” Ask which components were checked, what could not be evaluated, and what follow-up is recommended.
Separate the discussion into three questions:
- Current condition: What did the inspection establish?
- Unresolved work: Is there a defect, access limitation, or further evaluation needed?
- Future care: What servicing and monitoring will ownership involve?
An inspection describes conditions observed at that time. Treat it as information for a decision, not a promise that every component will last indefinitely.
Our septic inspection service page explains how to request an evaluation and what information to provide when you call.
4. Understand repairs before negotiating a credit
If the report identifies a problem, request a written scope for the proposed work. Ask what it includes, whether additional diagnosis is needed, who would perform it, and whether permits or further review are involved.
Discuss unresolved findings with your agent and lender before agreeing to a closing arrangement. A repair credit is easier to assess when it is based on a defined job instead of a rough guess.
Septic Pros quotes work individually. Call 877-996-9191 to discuss the findings and whether our confirmed repair services fit the job.
5. Check access and learn the operating routine
Ask the seller to show you the system locations from a safe distance. Do not lift tank lids or inspect electrical equipment yourself.
Before the handover, request:
- The location of accessible service points and any alarm panel.
- Instructions and records for the installed equipment.
- The current maintenance provider's contact details.
- Any access arrangements needed for a service vehicle.
- A clear explanation of the next maintenance action.
A practical handover should leave you knowing whom to call and where the records are. Keep that information with your other home documents rather than waiting until an alarm sounds.
6. Put the remaining questions in writing
Create a short list of open items before your inspection or closing deadline. Record the question, who will answer it, and when you need the answer. This might include a missing report, an unresolved repair, or confirmation of a proposed change to the property.
That list helps everyone discuss the same facts. Your agent and lender can address transaction requirements; TPCHD can confirm the applicable septic process; your septic professional can explain the inspection and service work.
