San Diego County is home to more than 3.3 million residents spread across 18 incorporated cities and numerous unincorporated communities — from the coastal neighborhoods of Del Mar and Coronado to the inland communities of El Cajon and Alpine. With such geographic diversity comes a wide range of auto insurance needs and rates.
In 2026, the average San Diego County driver pays approximately $2,180 per year for full coverage and around $640 per year for liability-only coverage — slightly above the California state average, driven by high vehicle values, dense traffic, and coastal weather exposure.
