What this actually means for a house in Livingston County

Neither at the 4 pCi/L action level nor down at the roughly 1.3 pCi/L national indoor norm, Livingston County's Zone 2 prediction lands in the gap between the two. A Zone 2 rating is a moderate county-wide average, not a guarantee about any one house in Livingston County — testing is the only way to know an individual home's actual level.

Testing and mitigation in Livingston County

A short-term test kit is the standard first step and typically costs far less than mitigation itself. If a test comes back at or above 4 pCi/L, a radon mitigation system for a typical home runs roughly $800–$2,500 (around $1,200 for a common single-family install), driven mainly by foundation type, not by county.
