About this site
Snohomish Septic Guide is an independent, privately operated website built to explain one specific thing clearly: Snohomish County's new point-of-sale septic inspection rule, effective November 1, 2026, and what it actually means for people buying or selling a home with a septic system.
What we are
- An informational guide that summarizes public reporting, county announcements, and general septic-industry cost data.
- A referral resource — if you want help finding a certified septic inspector serving Snohomish County, we can connect you with one through the form on our Find an Inspector page.
What we are not
- We are not Snohomish County government, the Snohomish County Health Department, or any Washington State agency.
- We do not perform septic inspections, pumping, repairs, or installations ourselves.
- We do not issue official inspection reports or file paperwork with the county on your behalf.
- Nothing on this site is legal, engineering, or real estate advice for your specific transaction.
How we make money
When you request a connection through this site, we may refer you to a certified septic inspector or related service provider serving your area. We're transparent that this is a referral relationship — our goal is to give you accurate, useful information whether or not you ever use our referral form.
Accuracy and corrections
We cite our sources throughout the site and try to be explicit about the difference between confirmed facts (county announcements, official fee schedules) and reported-but-unverified details (like specific mechanics around unresolved inspection deficiencies). If you find something on this site that's inaccurate or out of date, we want to know — email us and we'll correct it.
