New Snohomish County Septic Rule Every Home Seller Should Know Before November 1

Written By Keith Bruce

Starting November 1, 2026, Snohomish County requires a certified septic inspection, tank pump if needed, and an as-built site plan before any home with a septic system can close. Sellers submit a Report of Property Transfer plus a $245 fee; approval takes up to 10 days and stays valid 12 months. Systems installed in the past year are exempt. Unresolved deficiencies don't block the sale — they transfer to the buyer, so timing matters. With roughly 84,000 septic systems countywide, Keith Bruce of Sound Point Real Estate is already walking Everett-area sellers through the paperwork early. soundpointre.com
