Within Connecticut, premium dispersion across ZIP codes is substantial: the most expensive ZIP (06830 in Greenwich) charges 623% more than the least expensive (06790 in Torrington), reflecting local differences in catastrophe exposure, construction costs, and claims history. The FIO dataset aggregates voluntary reporting from the 40 largest homeowners insurers covering roughly 80% of the U.S. market, so ZIP-level figures represent market averages rather than individual quotes; actual premiums vary with dwelling value, deductible, coverage limits, and insurer-specific underwriting. This page is for educational research only and is not insurance advice — homeowners should obtain quotes from multiple licensed carriers or an independent agent before purchasing or renewing coverage.
