Service areas
We cover the West Puget Sound metros and the rural areas around them, where private septic systems and transfer inspections are most common. Each city page carries its county specifics, starting with the Thurston County lane around Olympia and Lacey.
The county matters more than the city here, because the rule that drives most septic calls, the inspection tied to a property changing hands, is written county by county. Each city page below names its county office, cites the rule that applies, and covers what the required work costs where published figures exist.
