Why Sonoma County’s Aging Population Could Be the Biggest Force in Real Estate Today.

Why Demographics Matter More Than Ever in Sonoma County Real Estate

When thinking about buying or selling a home in Sonoma County, most people focus on mortgage rates, inventory, or seasonal trends. But behind the scenes, a much bigger force is at play: demographics. And it’s shaping the future of our local real estate market in powerful ways.

The Silver Tsunami and Sonoma County's Demographic Shift

Housing markets are driven by supply and demand—and demand is deeply influenced by who lives in a region and what stage of life they’re in. Right now, Sonoma County is undergoing a major demographic shift known as the “Silver Tsunami”—a growing wave of aging homeowners who will significantly impact the market for decades to come.

Millennials, the largest generation in U.S. history, are now in their prime homebuying years. Meanwhile, Baby Boomers are staying in their homes longer, and many are purchasing new properties using cash—especially in lifestyle-driven destinations like Sonoma County.

According to the National Association of Realtors, nearly 50% of older Boomers and 40% of younger Boomers are buying homes all-cash, meaning they're largely unaffected by rising mortgage rates. This gives them a strong advantage in today’s competitive market.

However, this growing population of older adults is also holding onto homes, tightening inventory for younger buyers—and creating new questions around downsizing, multigenerational living, and aging in place.

Sonoma County Is Aging—And Fast

Sonoma County has one of the oldest median ages among California counties, with a large portion of the population over 55. The aging trend is expected to accelerate: By 2030, nearly 1 in 3 Sonoma County residents will be over the age of 60, according to county data.

Many of these older residents live in homes that may no longer suit their needs—such as rural properties with steep driveways or homes with stairs that are harder to navigate as they age. For some, aging in place can become a burden. And when aging homeowners choose to sell or relocate, they open up housing opportunities for younger families—but only if they’re able and willing to make that move.

Why This Matters for Sellers

If you're a Baby Boomer in Sonoma County, understanding these trends can help you make smart, forward-thinking decisions. Whether you're considering downsizing, relocating, or transitioning into a more accessible home, doing so before a crisis hits gives you more control—and often, a better financial outcome.

Sonoma County homes that are well-located, single-story, and updated for aging residents (or families looking to avoid costly renovations) are in high demand. Especially in communities like Sebastopol, Healdsburg, Santa Rosa, and Glen Ellen, where lifestyle buyers, retirees, and Millennial families are actively searching.

Selling your home now—while demand remains strong—could allow you to unlock equity, simplify your lifestyle, or transition into a more suitable living situation.

Why This Matters for Buyers

If you're in the market to buy, watching demographic shifts can help you make smarter decisions. Homes near amenities, walkable downtowns, public transit, or healthcare centers may see increased demand from older buyers and multigenerational families alike.

We’re also seeing a rise in multigenerational housing in Sonoma County, where adult children are co-buying properties with their parents, pooling resources to afford larger homes and support shared living. This isn’t just a workaround for affordability—it also creates built-in family support, which can be essential as family needs evolve.

The Risks of Waiting

For some homeowners, the idea of selling now may feel premature. But waiting too long—especially if health or mobility issues arise—can make selling more stressful and reduce your options. Additionally, if too many aging homeowners list their properties around the same time in the coming decade, it could flood the market and drive down prices.

Starting the conversation early about downsizing or transitioning can help you stay ahead of the curve—and avoid being “stuck in place” later.

The Bottom Line

Sonoma County real estate is being shaped by a powerful force: demographics. The Silver Tsunami is already underway, and its impact will be felt across the market—from inventory shortages to shifting buyer preferences.

Whether you're thinking about selling your long-time home, buying a property that will grow with your family, or planning a multigenerational purchase, understanding these trends will help you make informed, strategic choices.
