Property conveyance inspection (PCI) before a sale

Kitsap Public Health District reviews the records, inspects the system, and gives you a written report. The District's current onsite rules are Board of Health Ordinance 2025-01 (effective March 17, 2025), and the sale step is Section 13.D. Know where your septic tank, drainfield and reserve area are before the inspector arrives; the District's Homeowner's Guide covers how to protect them.

Wells and small water systems at sale

Since March 4, 2019, any property served by a private (1- or 2-party) well or a Group B water system needs a Water Status Report from the Health District before it is sold; apply about 30 days ahead so issues can be fixed before closing. Group A water systems are exempt.
