Rising costs, ageing populations, and caregiving needs are driving a global shift toward multi-generational living, with US and Indian real estate data confirming this growth
Multi-generational living, once dismissed as a fading tradition, is emerging as one of real estate's most consistent demand drivers. Data from the United States and India — two markets with very different housing histories — now point to the same conclusion: families are choosing to share a roof, and developers are racing to design for it.
The numbers behind the shift
In the United States, the National Association of Realtors' (NAR) 2026 Home Buyers and Sellers Generational Trends Report found that 17% of all home buyers purchased a multigenerational home between July 2023 and June 2024, up from 14% the year before. Generation X, buyers aged 46 to 60, led the category at 19-21% depending on the survey year, primarily to accommodate ageing parents or adult children moving back home.
Pew Research Center data adds historical depth to this trend: the number of Americans living in multigenerational households has quadrupled since 1971, rising from 7% of the population then to 18% by 2021. What was once a niche arrangement is now a mainstream household structure.
The financial angle is significant too. Realtor.com's research found multigenerational homes now command a 65% price premium over standard listings in the US, yet still draw 13.5% more page views than comparable properties and sell in a similar median timeframe. Demand, it seems, is absorbing the premium rather than being deterred by it.
Housing stock is adapting unevenly to this demand. HouseCanary's 2026 Multigenerational Living Index found only 23% of US homes have four or more bedrooms and just 30% include basements — features that typically determine whether multiple generations can comfortably share a home. States with more of this stock, such as Utah and Minnesota, rank highest for multigenerational readiness, while the average four-bedroom home costs roughly 1.6 times as much as a smaller one, pricing many families out of the ideal setup.
India's return to an old norm
In India, multigenerational living carries deeper cultural roots, but it too declined with rising urbanisation and the spread of nuclear households before staging a comeback. Rising real estate costs, tighter household budgets and the practical benefits of shared caregiving are now pulling families back toward joint living arrangements, particularly in metro markets.
Developers have responded by reworking floor plans: reports note a shift toward larger apartments and a rising preference for "independent floors" — separate living spaces within a shared property that allow privacy alongside proximity. Average apartment sizes launched in recent years have grown, reversing the compact-home trend that dominated the pre-pandemic market.
This dovetails with broader momentum in India's residential sector, which Mordor Intelligence values at over $400 billion in 2025 and projects to nearly double by 2031, driven partly by softer mortgage rates and expanding housing corridors in Tier-2 cities — markets where multigenerational households are especially common due to lower per-capita housing stock.
Why now
Three forces are converging across both markets: affordability pressure that makes pooling incomes attractive, an ageing population that needs proximity-based caregiving, and a cultural recalibration among younger buyers who no longer see shared housing as a compromise. Luxury real estate has caught on too — Sotheby's International Realty's 2026 Luxury Outlook Report notes that even affluent buyers are purchasing multigenerational properties, framing them not as cost-saving measures but as long-term family and wealth-legacy investments.
What it means for the market
For developers and planners, the implication is structural, not cyclical. Homes with flexible layouts — in-law suites, independent floors, additional bedrooms and separate entrances — are outperforming standard listings on buyer interest despite costing more. Markets that fail to adapt housing stock to this demand, as HouseCanary's data on bedroom and basement scarcity shows, risk leaving a fast-growing buyer segment underserved.
The multigenerational home is no longer a stopgap for stretched budgets. It is fast becoming a defining category of housing demand — one that spans continents, income brackets and generations, and one the real estate industry is only beginning to design around.
