A growing share of homes in the California housing market are no longer being bought by first-time buyers but passed down within families, with new data showing that in 2025 roughly one in six properties changing hands in the state went to an heir, and in some coastal counties as many as one in four. The figures, compiled by property data firm Cotality from county deed records and highlighted by economists and housing experts this year, have fuelled warnings that California’s housing system is hardening into what one analyst bluntly calls a ‘caste system’ based on family wealth.
The news came after a fresh look at who actually ends up owning homes in some of California’s most desirable postcodes. In Monterey, Santa Cruz, Napa and Marin counties, more than 25% of homes that changed ownership in 2025 did so through inheritance rather than a conventional sale, far above the already elevated statewide inheritance rate of 16% and double the national figure of 8%. Even at the other end of the spectrum, in more affordable Yuba County, inheritances still accounted for about 8% of transfers, matching the US average and underscoring that this is not just a coastal curiosity.
Across the California housing market, the pattern is starkest in wealthy coastal areas. In Marin County, north of San Francisco, about one in four homes that changed hands in 2025 went to an heir, according to Cotality. In San Francisco itself, the share was roughly 22%. Counties such as Santa Barbara, San Luis Obispo and San Mateo show similarly elevated rates, suggesting that in many high-cost communities, the main route into homeownership increasingly runs through a will, not an estate agent.
Cotality’s analysis covers single-family houses and condominiums and excludes properties where the use could not be determined. While the firm does not claim to capture every transfer perfectly, the trend is clear when set against earlier years. In 2000, Cotality estimates, only about 6% of California homes changing ownership went to heirs, roughly a third of the 2025 share. That shift has unfolded over a quarter of a century in which prices have galloped ahead of incomes and new building has failed to keep up with demand.
For context, California’s home prices are among the highest in the US, and supply is notoriously tight. Economists say the combination of restricted building, strong demand, and tax rules that reward holding property for decades has helped keep homes within families and out of the reach of younger buyers without wealthy parents. The result is a widening chasm between those born into homeowning households and those who are not.
‘When most people struggle to afford homeownership, but some people get to inherit homes without really trying, we don’t have a housing market — we have a caste system defined by family wealth,’ said Daryl Fairweather, chief economist at real estate brokerage Redfin, in a recent YouTube video. Her warning has resonated with younger Californians who are watching friends and colleagues step onto the ladder only through an inheritance.
Yet Cotality economist Matt Delventhal argues the rising inheritance share is not simply a story of more people dying and leaving houses to their children. He believes cycles in the wider housing market matter just as much. After the 2008 financial crisis, and again following the 2022 spike in interest rates, sales of new and existing homes fell sharply. When fewer properties are bought and sold, inheritances make up a bigger slice of the transfers that do occur.
There is a flip-side. Where counties have actively added to their housing stock, inheritances account for a smaller proportion of transfers. Comparing Cotality’s inheritance data for 2025 with state figures on housing growth from 2020 to 2025, higher-growth counties tend to see fewer homes handed down rather than sold. These are also the places where prices are somewhat lower and where, as economist Issi Romem of research group MetroSight notes, young families still have a shot at buying the ‘usual way’ with a deposit and a mortgage.
In places like Monterey or Santa Cruz, Romem said, the maths looks very different. With typical homes priced far beyond what middle-income households can comfortably afford, it can take decades to save a deposit. In that context, a bequest from parents or grandparents becomes less a windfall and more the only realistic path into ownership. ‘People know that unless they give their home to their kids, their kids have no shot at staying in California as homeowners,’ he said.
Tax policy quietly reinforces this dynamic. Selling a long‑owned home often triggers a substantial capital gains bill, since owners must pay tax on the rise in value since purchase, minus limited exclusions. In markets where properties routinely sell for seven figures, the available exemptions — up to $500,000 for married couples — are quickly exhausted. Passing the property on at death wipes out that gain for tax purposes in many cases, giving families a powerful incentive to hold rather than sell even when the house no longer suits their needs.
On top of federal rules, California’s own tax system has historically favoured keeping property in the family. Proposition 13, approved in the late 1970s, capped annual increases in property tax assessments for existing owners, meaning someone who bought in the 1980s can be paying far less tax than a neighbour who purchased last year. A subsequent measure in 1986 allowed those artificially low tax bases to be transferred to heirs, effectively baking intergenerational tax breaks into the system.
That changed in part with Proposition 19 in 2021, which tightened the rules so that heirs must use an inherited home as their primary residence to retain the low tax base and limited the benefit on high‑value properties. Some housing campaigners hoped the reform would unlock more homes for sale as inheritors opted to cash out rather than move in.
Delventhal is sceptical that it has had a transformative effect. He notes that many heirs do appear to live in the homes they inherit, rather than renting them out or treating them as holiday properties, so the supply released by Prop 19 may be more modest than advertised. There is nothing to confirm yet that the measure has materially loosened the market, and analysts caution that the early evidence should be treated with some care.
The state could go further. One option discussed by economists is to rejig property and inheritance tax rules so that keeping a family home is less fiscally attractive than selling it on, theoretically boosting supply and diluting the role of inheritance. Fairweather, though, argues that tweaking tax rules will only go so far if there are not enough homes to buy in the first place. In an email, she said that ‘building more dense housing in the places people most want to live’ would ease scarcity and ‘allow more young people to achieve homeownership without an inheritance’.
