Hawaiʻi’s federal rental-voucher spending has tripled since 2003 while the number of households receiving assistance has increased by only about 20%, according to a new University of Hawaiʻi Economic Research Organization analysis. The widening gap reflects a basic constraint: vouchers must cover rents in one of the country’s most expensive housing markets, leaving limited money to add recipients.

The study, released September 16, examined U.S. Department of Housing and Urban Development administrative records from 2003 through 2024. It found that roughly 12,000 low-income households use tenant-based Housing Choice Vouchers, commonly called Section 8, representing about 7% of Hawaiʻi renter households. Federal spending reached approximately $170 million in 2024, while the average monthly subsidy rose from about $560 to $1,400. That is above the national average of roughly $1,100, UHERO reported.

The program is HUD’s principal rental-assistance program, serving more than 2.3 million families nationally. In Hawaiʻi, five public housing authorities administer the tenant-based vouchers: the four counties and the Hawaiʻi Public Housing Authority. A participating household generally contributes about 30% of adjusted income toward rent and utilities, with the administering agency paying the balance up to its payment standard.

The pressure is particularly acute because Hawaiʻi’s median monthly rent is about $2,000, more than half of renter households are cost-burdened, and roughly one-third spend more than half their income on housing, the UHERO summary said. Only about one in five income-eligible renter households receives a voucher. The median voucher household had annual income of about $17,300 in 2024, compared with a statewide household median of about $100,400.

Capacity also differs sharply by administering agency. UHERO counted 4,483 vouchers under Honolulu, 2,748 under the state authority, 2,289 in Hawaiʻi County, 1,622 in Maui County and 880 in Kauaʻi County. Hawaiʻi County used between 93% and 100% of its allocated vouchers during the study period, while Maui generally used 98% to 99%. Honolulu’s utilization ranged from 63% to 82%, and Kauaʻi reached about 75% by 2024 after spending much of the previous decade near half utilization.

Those figures do not mean unused vouchers can simply be handed out without limit. Housing authorities must remain within federal funding, and recipients may lose a voucher if they cannot find a qualifying private-market unit with a willing landlord within 60 to 120 days. Aloha State Daily noted that landlord participation is voluntary, further narrowing the available pool.

The report recommends pairing rental assistance with policies that expand housing supply and with targeted workforce and economic-mobility programs. For residents, the immediate implication is less abstract: rising rents can consume new federal dollars without shortening waiting lists. As Hawaii News Now reported, the program is spending substantially more to keep roughly the same share of renters housed rather than broadening access at the pace of need.
