🏡 Buying or selling a home in Snohomish County with a septic system? There’s an important change coming November 1, 2026.
New septic property transfer requirements will add a few important steps to the process, including:
✔️ A septic inspection within 12 months of closing
✔️ Pumping if recommended
✔️ Verification of an as-built record, or a site plan if one isn’t on file
✔️ A new Report of Property Transfer (RPT) submitted to the Health Department
✔️ Buyers receiving the reviewed RPT, septic maintenance records, and required seller disclosure
If you’re selling, it’s a good idea to start early, ideally before listing, so these requirements don’t create unexpected delays.
If you’re buying, knowing what to expect can help you plan for the transaction and closing timeline.
