Selling a home in Picnic Point with a septic system can feel stressful, especially if you are not sure what inspectors or buyers will expect. You want a smooth closing, no last‑minute surprises, and top dollar. This guide gives you clear steps, documents to gather, estimated costs, and the rule changes Snohomish County sellers should know. Let’s dive in.
Why septic readiness matters in Picnic Point
Picnic Point homes often rely on on‑site sewage systems. In Snohomish County, Environmental Health maintains septic permits, as‑builts, and contractor certifications, and is your primary resource for records and guidance. Start at the county’s septic hub to confirm current policies and how to access your file. You can review local resources through the county’s Septic/OSS page.
Washington has adopted new OSS rules that add a property‑transfer inspection requirement starting February 1, 2027, unless your local health officer grants an exemption for jurisdictions that demonstrate compliance. Plan ahead, since buyers may already request an inspection and report as part of a sale. Review the rule language in the Washington State Register update.
What you must disclose in Washington
Washington requires most sellers to deliver the Form 17 seller disclosure. Disclose your water and sewer details, known septic defects, and maintenance history, then update if new facts arise before closing. You can read the statute that governs Form 17 in RCW 64.06.
Step‑by‑step workflow for Picnic Point sellers
A) Immediate records and contacts
- Contact Snohomish County Environmental Health to request scanned permits and as‑built drawings and to confirm any parcel‑specific transfer requirements. Start with the county’s septic permitting page.
- Gather your own paperwork: pumping and maintenance receipts, repair invoices, system design documents, manuals, and warranties.
B) Quick visual check
- Walk the tank and drainfield area and note any obvious issues. Common red flags include slow drains, odors, soggy or unusually green areas over the drainfield, or surface sewage. Review the county’s guidance on signs of septic failure, and schedule a professional evaluation if you see anything concerning.
C) Pumping and a pre‑listing inspection
- If your tank has not been pumped in about three years, consider ordering a pump‑out with an inspection before you list. A current report reduces surprises during escrow and supports accurate disclosure. Regional guidance puts combined pump and inspection commonly in the mid‑hundreds. See typical ranges in this overview of septic cleaning costs.
- Hire a Snohomish County–certified pumper or O&M specialist so your records are recognized. Verify certification and, if you have a proprietary treatment unit, confirm the contractor is authorized for that product. Use the county’s directory to find a septic contractor.
D) Decide on repairs or credits
- If the inspection finds issues, request written estimates from certified contractors. Minor fixes may be quick; drainfield work or replacement takes more time and permitting. Installation and major repair costs vary widely by system type and site, often ranging from several thousand dollars to the tens of thousands. For ballpark context, review regional replacement ranges for Everett‑area projects in this cost overview.
E) Prep your listing file
- Provide buyers with your completed Form 17, as‑builts and permits, maintenance and repair receipts, and any pre‑listing inspection or pump documentation. Keep dated copies of everything you deliver.
At offer and closing
Many purchase agreements include septic addenda that set responsibilities and timelines for inspections, pumping, repairs, and report delivery. Negotiate who pays for what and by when, then follow the contract. Snohomish County historically has not required the same county‑run pre‑closing inspection used in some other counties, but the new statewide rules that take effect in 2027 could change expectations. Confirm current requirements for your parcel with Environmental Health and plan for a third‑party inspection if requested by the buyer or required by regulation.
Costs and timing at a glance
- Routine inspection and pump: often roughly 400 to 900 dollars in the greater Seattle area, depending on access and scope. See this guide to cleaning cost ranges.

- Major repairs or replacement: can run several thousand to 20,000 dollars or more, depending on site conditions and system complexity. See regional ranges in this Everett‑area cost summary.

How to choose the right pro
- Start with the county’s certified list and verify current certification, insurance, and references.
