The framing of “downsizing” — smaller, less, a reduction — doesn’t capture what most people over 50 are actually seeking when they consider changing their living situation. What most people want is a home that fits the life they’re living now, not the life they were living when they bought it 25 years ago. Sometimes that means smaller. But it also might mean different: a different location, a different ownership structure, a different relationship to space and community. “Right-sizing” is a more accurate term for this project.
Here is a broader set of living options that are increasingly popular among over-50 homeowners who have concluded that their current situation no longer fits — and who are looking beyond the traditional move to a smaller version of what they have.
Accessory Dwelling Units: Adding Flexibility to the Current Property
An accessory dwelling unit (ADU) — a secondary housing unit on the same property as a primary residence — can serve multiple right-sizing functions. For homeowners who want to stay in their current home but reduce costs: renting the ADU provides income that offsets mortgage, maintenance, and tax costs. For homeowners who want to maintain their family property while reducing their own footprint: moving into a smaller ADU on the property while renting or hosting family in the primary house. For multigenerational families: housing adult children or aging parents in an ADU while maintaining appropriate separation.
ADU construction has been made significantly easier by regulatory changes in many states, particularly California, Oregon, and Washington, which have eliminated many of the local restrictions that previously made ADU construction difficult. Attached ADU construction costs run $80,000–$200,000; detached ADUs, $100,000–$350,000 depending on size and site conditions. Many states now offer ADU financing programs; Fannie Mae’s ADU programs allow ADU rental income to count toward mortgage qualification.
Multigenerational Living
The multigenerational household — two or more adult generations living under one roof — has become significantly more common in the US over the past decade, driven by housing affordability pressures, the caregiving demands of aging parents, and a genuine reassessment of the cultural preference for single-household living. For over-50 homeowners, sharing a home with adult children or grandchildren can reduce housing costs, provide built-in social connection, and create a caregiving infrastructure that supports aging in place.
The physical requirements of successful multigenerational living — separate entrances, sound insulation, defined private spaces, shared common areas that work for multiple generations — typically require either a home specifically designed for multigenerational use or a renovation that creates adequate separation. Builders including Lennar, Ryan Homes, and Clayton offer “NextGen” or “multigenerational” floor plans specifically designed for this use case; they have become among the most popular configurations in many markets.
Active Adult and 55+ Communities
Active adult communities — age-restricted communities where at least one household member must be 55+ — represent a significant and growing segment of the US housing market. These range from large master-planned communities (The Villages in Florida, Sun City communities in Arizona) to smaller boutique developments in urban and suburban settings. The appeal is community with shared life-stage identity, amenities designed for active older adults, and maintenance-free or low-maintenance living.
The financial structure varies: some are standard for-sale communities with HOAs; others use land lease models where you own the home but pay monthly ground rent for the land. The land lease model is significantly less expensive on a purchase price basis but carries risks — ground rent can increase, and resale values in land-lease communities are often lower and less predictable than in fee-simple communities. Understanding the ownership structure before purchasing is essential.
Co-Housing: An Alternative Community Model
Co-housing communities — intentional communities designed around shared values and common spaces, with private units and community-owned shared facilities — have a small but growing presence in the US, with a particularly strong concentration in the Pacific Northwest and New England. Senior co-housing specifically is designed for older adults and combines the independence of private ownership with the community infrastructure of intentional living: shared meals several times per week, shared gardens, tool libraries, mutual support systems.
Co-housing is not for everyone — it requires genuine investment in community relationships and shared decision-making. For the right person, it provides the social density and mutual support that suburban single-family homeownership structurally cannot, at a lower cost than assisted living and with significantly more autonomy.
