Banks and mortgage lenders typically require proof of safe drinking water. The “Idaho Rules for Public Drinking Water Systems” (IDAPA 58.01.08) requires properties served by a community public water system (i.e., serving at least 15 connections or 25 people who live there year-round) to provide a Consumer Confidence Report (CCR). If the property uses a private well, lenders may require certified lab testing to confirm water quality. Contact your water provider for a CCR copy.
