Ada County, Idaho Eviction Risk: Very Low

Ada County scores 2.1/10 (Low risk) on the EvictionRiskMap scale, making it one of the more landlord-friendly markets in Idaho eviction laws. Spread across 9 cities and home to roughly 458,926 residents, the county sits at rank 38 of 44 in the state, meaning 37 Idaho eviction laws counties carry higher eviction risk. Only 6 counties are less risky. With an average rent of $1,609 and a rent burden of 29.7%, tenant financial stress here is relatively contained compared to the state at large, and a renter share of just 30.2% of households means you are operating in a predominantly owner-occupied market where turnover pressure is modest.

Within the county, scores span a tight band of 1.7 to 2.3, so conditions are broadly favorable but not uniform. Investors evaluating specific submarkets will find meaningful differences city to city, and those differences matter when underwriting vacancy assumptions or screening strategies.

The cities inside Ada County

At the high end of the county range, Kuna (population 27,158), Star (population 14,745), and Hidden Springs (population 3,378) each score 1.9/10, the county ceiling. Boise City, the county seat with a population of 237,242, and Eagle (population 32,855) both come in at 1.9/10. These scores are still Low by any national standard, but they reflect slightly more compressed rental markets and a modestly higher concentration of cost-burdened renters than the quieter corners of the county.

The most landlord-favorable conditions are in Meridian eviction risk, the county's second-largest city at 130,138 residents, which scores just 1.5/10. Garden City and Avimor each score 2.3/10. That spread, from 1.5 in Meridian to 2.5 in Kuna, illustrates why risk is genuinely hyper-local: two properties ten miles apart can carry materially different operating profiles even within the same low-risk county.

An uncontested eviction can resolve in 21 to 45 days; a contested case stretches to 45 to 120 days.
