About Cost of Living in Kauai County, Hawaii
Kauai's rent burden mirrors national strain
Kauai County's 23.2% rent-to-income ratio slightly exceeds the national norm, despite a median household income of $93,612 that's 25% above the U.S. average. Monthly rent of $1,810 reflects the island's tourism economy and limited housing supply.
Second-most expensive county in Hawaii
Kauai County ranks second from last among Hawaii's counties for affordability, with a 23.2% rent-to-income ratio above the state average of 22.1%. Only Honolulu's 23.6% ratio exceeds Kauai's burden, making the Garden Isle a pricey destination for renters.
Kauai rents steeper than most counties
Kauai's $1,810 median rent exceeds Hawaii County and Kalawao but trails Honolulu and Maui slightly. Despite the island's smaller population and rural character, housing costs rival those of more urbanized counties—a reflection of limited inventory and strong vacation-home demand.
Nearly a quarter of income toward housing
Kauai residents dedicate 23.2% of their $93,612 median household income—roughly $1,810 monthly—to rent alone. Homeownership runs similarly steep at $1,834 per month, with median home values of $817,900 placing ownership beyond many locals' reach despite reasonable incomes.
Kauai: beautiful but budget-demanding
Kauai's scenic beauty and slower pace come at a housing cost nearly matching Honolulu's affordability squeeze, despite its smaller size. If you're considering the Garden Isle, ensure your household income can comfortably absorb the 23.2% housing burden plus Kauai's higher cost of living overall.
