Hawaiʻi is barreling toward a housing shortfall that could reshape life on the islands, with nearly 60,000 new homes needed by 2050 as the population grows older and grayer. Most of that demand will hit fast, by 2035, just as rising housing costs and an older household mix threaten to push younger workers off island and thin out the local caregiving workforce. Lawmakers and advocates warn that closing the gap will take both more homes and deliberately affordable ones to keep families and caregivers in the state.
How the Housing Gap Was Tallied
A report prepared for AARP Hawaiʻi finds the state will need 59,669 additional housing units by 2050, with about two thirds of that demand, roughly 39,000 units, arriving by 2035. The analysis, produced by Econorthwest using 2024 U.S. Census data, notes that Hawaiʻi added about 43,000 units between 2014 and 2024, while household growth during the same stretch still outpaced the new supply.
How Aging Hawaiians Are Driving Demand
A study from the University of Hawaiʻi Mānoa’s Economic Research Organization projects that roughly one in four residents will be 65 or older by 2035. UHERO says that shift will place more people in the 75-plus age group and increase the need for higher-acuity care. That accelerating “aging within aging” ratchets up long-term pressure on public services and on the working-age residents who provide health and home-care services.
Where the New Homes Will Have to Go
Honolulu Civil Beat reports that residents 65 and older will account for about 44,000 of the new units, and that Honolulu County alone will need an estimated 48,299 additional homes by 2050. Neighbor islands are not spared: Kauaʻi needs roughly 5,390 new units by 2050, an 18 percent increase over its current housing stock.
Affordability and the Policy Tightrope
The AARP analysis calls for boosting overall housing supply, cutting regulatory and infrastructure obstacles that slow construction, and prioritizing homes that allow kūpuna to age in place. AARP Hawaiʻi also highlights a package of bills at the Legislature, from rent supplements for kūpuna to incentives for transit-oriented and deed-restricted affordable housing, as tools that could help close the gap. The report stresses that a substantial share of the needed units must be affordable to households at or below about 60 percent of area median income, around $63,900 in many parts of the state.
Young Adults Are Already Bailing Out
As Civil Beat summarizes from the analysis, Hawaiʻi now has one of the nation’s worst retention rates for people ages 20 to 30, ranking behind only Alaska and Wyoming. U.S. Census data show nearly half of Hawaii-born people in that age bracket now live on the mainland. Fewer young residents translates into a smaller labor pool for hospitals, home-care agencies and other services that let older neighbors stay in their communities.
What Lawmakers Are Up Against
Advocates say closing the shortfall will require a blend of new construction, preservation of existing affordable units and stronger supports for caregivers and low-income kūpuna. UHERO’s framework underlines that these are fiscal choices as well as social ones: if the state does not act, Hawaiʻi’s shifting age structure is expected to add strain to public budgets and local services while reshaping who works and who is cared for across the islands.
