These Are the Best (and Worst) States for Multigenerational Families Living Under One Roof, and the Gap Between Them Is Absolutely Massive

Utah ranks as the best state in the country for multigenerational households, while Arkansas, Mississippi, and Louisiana rank among the worst, according to HouseCanary’s 2026 Multigenerational Living Index. The gap between them is stark: 41% of Utah homes have four or more bedrooms versus just 7% in Arkansas, and Utah homeowners pay a 1.39x premium for that extra space compared to roughly 1.85x to 1.86x in the bottom-ranked states. That matters more than it used to — 17% of all homebuyers in 2025 purchased a home specifically to house multiple generations, per the same report, up from a share that barely registered a decade ago.

How HouseCanary Built the Ranking

The index scores states on three equally weighted measures: the share of homes with four or more bedrooms, the share of homes with basements, and the price premium homebuyers pay for a four-bedroom home compared to smaller ones. Those three factors were chosen because they capture the two things a multigenerational household actually needs — enough separate space for multiple adult generations to live semi-independently, and whether that space costs a manageable amount more or a prohibitive amount more, according to HouseCanary’s methodology.

The Best States, and Why They Win

Utah takes the top spot, with 41% of homes offering four or more bedrooms, 53% including a basement, and only a 1.39x price premium for the larger option. Minnesota ranks close behind, with 29% of homes at four-plus bedrooms, 65% with basements, and a 1.44x premium. Ohio follows with 24% four-bedroom-plus homes, a striking 71% basement rate, and a 1.56x premium. Colorado, Idaho, and Wyoming all clear the national benchmarks on both large-home share and basement availability as well, per HouseCanary’s data, forming a cluster of Mountain and Midwest states where bigger homes simply cost less to reach.

The Worst States, and What’s Working Against Them

Arkansas lands at the bottom, with only 7% of homes offering four or more bedrooms and a 1.85x to 1.86x price premium for the ones that do. Mississippi (12% four-bedroom-plus) and Louisiana (8%, with a basement rate of just 0.1%) rank similarly low, alongside South Carolina and Oklahoma. In each case, the problem isn’t just a shortage of large homes — it’s that the large homes which do exist carry a steep price jump, roughly a third higher than the premium buyers pay in Utah for the same upgrade.

Why Basements Matter as Much as Bedroom Count

A finished or even unfinished basement functions as a built-in semi-separate living space — exactly what multigenerational households look for when an adult child, aging parent, or extended family member needs privacy without a second mortgage or an addition. Nationally, only 30% of U.S. homes include basements, per HouseCanary’s report, which is part of why the states combining high basement rates with high four-bedroom rates — Ohio’s 71% basement share is the standout example — separate themselves so clearly from states where neither exists at meaningful scale.

The National Numbers Behind the State Gap

Zoom out from individual states and the shortage is a national one: only 23% of U.S. homes have four or more bedrooms at all, and the ones that do cost roughly 1.6 times more than homes with one to three bedrooms, according to HouseCanary. That premium is the real obstacle for multigenerational buyers regardless of state — it’s not that larger homes don’t exist, it’s that the ones which do are priced as a distinct, more expensive category rather than a modest step up from a standard three-bedroom house.

Why This Is Becoming a Bigger Piece of the Market

Multigenerational households aren’t a fringe housing category. 74% of multigenerational households own their homes, based on 2022 data cited in HouseCanary’s report, and with 17% of all 2025 homebuyers purchasing specifically for multigenerational use, this three-metric ranking isn’t an academic exercise — it’s mapping where a rapidly growing share of buyers can actually find what they’re shopping for at a price that doesn’t punish them for needing the extra space. HouseCanary’s own framing is direct: states that offer adaptable home layouts without steep price increases are better positioned to meet the demographic shift already underway.

The states doing well here aren’t the ones with the most large homes in absolute terms — they’re the ones where a bigger home doesn’t cost dramatically more than a standard one. That’s a subtly different problem than a housing shortage, and it’s one a handful of Midwest and Mountain states have solved almost by accident.
