San Diego County, California Eviction Risk: High

San Diego County posts a county-wide eviction-risk score of 8.7/10 (High), placing it 21st of 58 California counties, where rank 1 is the highest-risk. That means 20 counties are riskier and 37 are less so, putting San Diego County squarely in the middle third of the state. For a landlord or investor, that average signals real operational friction: an average rent of $2,275, a renter share of 46.3% of households, and a rent burden averaging 34% of income all point to a tenant base under meaningful financial pressure, which historically correlates with elevated non-payment and eviction-filing rates. Property management in San Diego County requires close attention to California's layered regulatory framework on top of those market conditions.

The 6.5 county average, however, conceals a spread from 7.2 to 8.7 across 56 cities. That 2.4-point range is wide enough that picking a submarket at the wrong end of it meaningfully changes your operating risk. Investors comfortable with the county's mid-tier state ranking should still treat individual city scores as the primary underwriting input, not the headline average.

The cities inside San Diego County

The highest-risk corners of the county are concentrated in the East County corridor. Casa de Oro-Mount Helix tops the list at 8/10, the county's maximum. El Cajon, a city of 104,449 residents, sits at 8.2/10, matched by Bostonia at 7.5. Lemon Grove follows at 7.3, and Escondido, with a population of 149,668, reaches 7.8/10. Vista, at 7.9/10, rounds out the upper tier. These jurisdictions have above-average eviction-risk profiles even relative to other elevated-score California counties.

The lower end of the range looks considerably different. Carlsbad scores 8.1/10, the county's lowest tracked city, and the city of San Diego, the county seat and home to 1,389,526 residents, comes in at 6.4/10. San Marcos lands exactly at the county average with a 6.5. The gap between Carlsbad eviction risk and Casa de Oro-Mount Helix is 1.6 points, which is a meaningful difference in practical eviction frequency and carrying cost. Working with experienced San Diego County property managers who track these submarket differences can reduce the likelihood of placing tenants in higher-risk situations.

State-level laws that apply here

Every landlord in San Diego County operates under California state law, which sets the procedural floor regardless of local ordinances. Non-payment of rent triggers a 3-day notice under CCP § 1161(2); curable and incurable violations also carry 3-day notices. No-cause terminations require 30 days for tenancies under one year or 60 days for tenancies of one year or more under Civ. Code § 1946.1. Just-cause no-fault terminations, including owner move-in and substantial remodel, require 60 days. Once notice periods expire without compliance, an uncontested unlawful detainer typically resolves in 35 to 60 days; a contested matter runs 75 to 180 days. Landlords should budget court filing fees of $240 to $435, sheriff lockout fees of $75 to $145, and attorney fees of $1,500 to $4,500 depending on case complexity. The California eviction process also imposes AB 1482 just-cause requirements and a rent cap of 5% plus CPI, capped at 10% under Cal. Civ. Code § 1947.12 for qualifying units. Fully understanding California eviction costs before acquiring property here is essential to accurate pro-forma modeling. The Costa-Hawkins Act limits but does not preempt local rent control on pre-1995 multi-unit buildings, so older stock in cities with their own ordinances carries additional exposure beyond state minimums.

With a poverty rate averaging 10.5% across the county and nearly half of all households renting, the 56-city grid above is the most reliable tool for pinpointing where in San Diego County that elevated 6.5 county average is concentrated and where the pockets of relatively lower risk actually sit.
