A statewide measure on the November ballot would let California lend middle-income buyers most of their down payment — but only on newly built homes, a category San Francisco produces almost none of at prices the program allows.

Proposition 37 asks voters to authorize up to $25 billion in state-backed loans so buyers can put just 3% down instead of 20%. Its backers frame it as a lifeline for a shut-out middle class. But the fine print — new construction only, repaid as a monthly second mortgage — means the help flows toward where California actually builds, which is rarely the high-cost coast. For a San Francisco household, the measure's generous income ceiling collides with a near-total absence of qualifying homes.

California's median home sold for about $778,000 in June, which pencils out to roughly $156,000 up front at the conventional 20% — many times what a typical household keeps in the bank. Proposition 37, on the November 3 statewide ballot (external source, opens in a new tab), is pitched as the fix.

The measure would let the California Housing Finance Agency (CalHFA) borrow as much as $25 billion through revenue bonds and lend qualified buyers up to 17% of a home's price. Add a 3% buyer contribution and the total reaches the 20% mark that spares buyers private mortgage insurance; a conventional mortgage covers the balance. And per the state's Legislative Analyst's Office (external source, opens in a new tab), the whole thing lands on the ballot carrying "no direct state or local costs" — buyers, not taxpayers, retire the bonds through their own payments.

Where the measure narrows is eligibility. A California Budget & Policy Center analysis (external source, opens in a new tab) notes the loans apply only to newly built homes, or nonresidential buildings freshly converted to housing, and only when the applicant is the first buyer. Household income can reach 200% of the local Area Median Income — a ceiling that, by the group's math, a Santa Clara County family of four earning close to $375,800 could still clear, against about $166,800 in Madera County. Eligible prices top out near $1 million across much of the state and stretch toward $1.5 million in the costliest counties.

That is precisely the mismatch in San Francisco. New for-sale housing here skews to luxury condos or income-restricted affordable units; middle-market, first-sale homes under the cap barely register in the pipeline. So a policy sold as demand-side help behaves, in practice, more like a construction subsidy — dollars that reward building and therefore surface wherever building is easiest, which is seldom the coast. That reading tracks with the San Francisco Chronicle, which first laid out the measure's mechanics and quoted an economist drawing the same supply-versus-demand distinction.

The repayment design compounds the problem. The Budget Center points out that CalHFA's current programs, MyHome and Dream for All, use deferred "silent second" loans that come due only at sale or refinance, so they never fight groceries and utilities for room in a monthly budget. Prop 37 cannot work that way: because the bonds must be serviced from program income, its second loan is "likely to require monthly payments," write report authors Monica Davalos, Nishi Nair and Kristin Schumacher, possibly at a rate above the primary mortgage. Their bottom line: the measure may not meaningfully reach the middle-class Californians most shut out of ownership. They add that, because revenue bonds skip voter approval, lawmakers or CalHFA could have stood up a similar program without a ballot campaign at all.

That campaign is well-armed. The initiative is led by Bob Hertzberg, a Los Angeles Democrat who once ran the state Assembly as its speaker and later served as a top Senate leader; he has said flatly that "people don't think homeownership is attainable" and estimates the program could generate 190,000 new homes. Backers include the California Association of Realtors and the Northern California Carpenters Regional Council, alongside endorsements from gubernatorial candidate Xavier Becerra, San Jose Mayor Matt Mahan, former Rep. Katie Porter and former Los Angeles Mayor Antonio Villaraigosa. No committee had registered against it as of mid-summer.

In a city where the median home already clears seven figures, the question Prop 37 leaves for San Francisco voters isn't whether 3% down would help. It's whether the homes it covers will ever get built here.
