Thinking about selling your home on septic? In many areas—especially King and Snohomish counties—a time-of-sale septic inspection is required. Skipping it can stall your closing or slash your sale price. In this video, we show exactly what inspectors check, what it costs, and how to avoid delays.
You’ll learn:
- Why a time-of-sale inspection protects you and the buyer
- What’s inspected: lids, scum/sludge levels, baffles (inlet/outlet), pump & alarm
- How pros evaluate primary & reserve drainfields (and signs of failure)
- What gets filed with the county and becomes public record (King County rules)
- Typical costs: $600–$800 for the inspection + county filing fees
- Pro tip: Schedule early in case repairs are needed before closing
