Napa County, California Eviction Risk: High

Napa County carries a county-average eviction-risk score of 8.2/10 (High), placing it in the lower-risk third of California -- 45 of the state's 58 counties score higher and present a harder operating environment for landlords. That relative positioning is meaningful, but the 14 incorporated cities and unincorporated communities spread across the county produce a score range of 7.6 to 8.5, wide enough that a landlord's experience in Napa County depends heavily on which specific address they own. Average rent sits at $2,281 per month, with renters directing 33.7% of their income toward housing on average -- a burden level that contributes modestly to payment stress but does not dominate the risk picture the way it does in California eviction laws's coastal urban cores.

Renters make up 37.8% of Napa County's occupied housing, a share that is relatively contained compared with denser metro markets. That mix -- wine-country tourism economy, small municipal governments, and a predominantly owner-occupied stock -- shapes an environment where lease enforcement tends to proceed more predictably than in the state's major urban counties, even as California eviction laws's statewide tenant-protection framework applies uniformly throughout.

The cities inside Napa County

The county's highest-risk municipality is Eldridge, which scores 8.5/10 and is home to 21,691 residents -- the second-largest city in the county and the one where landlords face the most constrained operating conditions. Rutherford follows at 7.6/10, and both Fetters Hot Springs-Agua Caliente and Angwin score 8/10. These communities at the top of the range reflect the concentrated renter populations and local regulatory dynamics that push risk above the county average.

At the other end, St. Helena scores just 7.9/10, the lowest in the county, making it the most landlord-favorable market within Napa County. Calistoga and Yountville both land at 8.2/10. The 1.7-point spread between St. Helena and American Canyon is a material difference -- it represents a gap between market tiers that matters for portfolio planning. Investors evaluating individual acquisitions should treat the city-level scores in the grid above as the operative figure, not the county average.

State-level laws that apply here

Every landlord operating anywhere in Napa County works under California eviction laws's statewide eviction framework. Non-payment of rent and curable lease violations each require a 3-day notice before filing (CCP § 1161). No-cause terminations require 30 days for tenancies under one year and 60 days for tenancies of one year or more (Civ. Code § 1946.1). Under AB 1482, just-cause eviction requirements apply to most multi-unit buildings statewide, and annual rent increases are capped at 5% plus CPI, with a 10% ceiling (Cal. Civ. Code § 1947.12). Landlords should review the California eviction laws eviction process carefully before serving any notice, since procedural missteps restart timelines. Court filing fees run $240 to $435, sheriff lockout fees add $75 to $145, and attorney fees typically range from $1,500 to $4,500. Uncontested cases resolve in 35 to 60 days; contested matters can extend to 75 to 180 days. A full breakdown of California eviction costs is essential reading before budgeting any enforcement action.

With a poverty rate of 8.6% and renters representing 37.8% of occupied housing units, Napa County's risk profile is shaped as much by its small-city character as by any single economic stressor -- the city-by-city grid above is the most reliable tool for comparing specific markets within the county.
