Multigenerational buying has become a real, measurable trend rather than a niche exception, and the Peninsula’s price point makes it a particularly practical strategy here. According to the National Association of Realtors’ 2026 Generational Trends Report, 14% of all buyers purchased a multigenerational home last year, and the reasons behind that shift line up closely with what many Peninsula families are already navigating.

Why Families Are Combining Households

Reason Share of Multigenerational Buyers
Caring for aging parents 41%, the highest share since tracking began
Cost savings 36%
Adult children moving back home 27%
Adult children who never left 21%

Gen X buyers, often called the sandwich generation for simultaneously supporting aging parents and adult children, purchase multigenerational homes at the highest rate of any group, at 19%. On the Peninsula specifically, where entry-level pricing still starts well above a million dollars, pooling resources across generations is often less about lifestyle preference and more about genuinely practical math.

What to Look For When Shopping Multigenerational

Not every home layout supports multiple generations comfortably. A few features consistently matter most: a ground-floor bedroom and full bathroom for aging parents who may eventually have mobility limitations, a layout with some separation between living areas rather than one continuous open floor plan, and enough parking and storage for multiple adult households sharing one address. Homes with an existing en suite guest room or a finished lower level tend to convert to multigenerational use far more easily than a typical single-family layout designed around one nuclear family.

The ADU Connection

A growing number of Peninsula multigenerational buyers are pairing this strategy with an ADU, either an existing one or one they plan to build, since it offers aging parents or adult children genuine privacy and independence while staying on the same property. Some new construction in the area, including certain Thomas James Homes builds, now comes with a private ADU already included specifically for this purpose.

Financing a Multigenerational Purchase

Combining incomes across generations can genuinely help qualify for a larger loan, but it also means combining credit profiles and debt-to-income ratios, which a lender will evaluate carefully. It is worth discussing early with a lender exactly how co-borrowing works, whether all parties will be on title, and how ownership would be handled down the line, ideally with an estate attorney involved before you write an offer, not after.

Key Takeaway

Multigenerational buying is no longer a niche strategy. It is a mainstream response to both family caregiving needs and genuine affordability pressure, and the Peninsula’s price point makes it a particularly practical option for many families here.
