Housing Vacancy Rate by Zip Code (ZCTA5) — Connecticut

NOTE: Gray indicates insufficient data or a suppressed estimate.

The northwest corner of Connecticut exhibits the highest housing vacancy rates, with several zip codes exceeding 20–30%, consistent with the region's prevalence of seasonal and vacation properties in the Litchfield Hills area. Coastal zip codes along Long Island Sound and the southwestern Fairfield County corridor generally display lower vacancy rates in the 0–4% range, reflecting tight housing markets in commuter-heavy suburbs near New York City. A scattered pattern of moderate vacancy (8–12%) appears across the central Connecticut River Valley, while pockets of very low vacancy near Hartford and New Haven likely correspond to high-demand urban cores interspersed with higher-vacancy neighborhoods.
