Proposition 37 Passes: California’s New Down Payment Loans for Newly Built Homes

On November 3, 2026, California voters approved Proposition 37, the California Middle-Class Homeownership and Family Home Construction Act. It creates a state loan that can cover up to 17 percent of the purchase price of a newly built home. With the buyer’s own 3 percent, that adds up to a 20 percent down payment.

The Associated Press called the measure on November 4 with about 61 percent of counted votes in favor. No argument against it was filed for the official voter guide. This article covers what the measure does, who qualifies, which homes are eligible, and what is still undecided. A companion article covers what Prop 37 means for buyers of SB 684 and AB 1751 homes.

What Proposition 37 Does

Prop 37 authorizes the California Housing Finance Agency (CalHFA) to issue up to $25 billion in revenue bonds. CalHFA lends the money to eligible buyers as a “middle-class homeownership loan.” The loan is a fixed-rate second mortgage, repaid each month alongside the buyer’s regular first mortgage.

Buyers’ payments repay the bonds and cover the program’s administrative costs, not the state General Fund. The Legislative Analyst found no direct state or local cost. CalHFA decides how much of the $25 billion to issue and when, and the measure directs it to keep interest costs for buyers as low as possible.

How the Numbers Work

Take a newly built home priced at $1,000,000. Under Prop 37 the purchase could be financed like this:

• Buyer’s own funds: at least $30,000 (3%)
• Prop 37 loan: up to $170,000 (17%)
• First mortgage: $800,000 (80%)

A first mortgage at 80 percent of the price generally does not require private mortgage insurance. The buyer still makes two monthly payments, one on each loan, and must qualify for both. The Prop 37 loan is not a grant, and the buyer does not share any of the home’s appreciation with the state.

Who Qualifies

An applicant must meet all of these requirements:

• Has lived in California for at least one year before applying.
• Has a family income no higher than 200 percent of area median income for a family of the same size in the county or metro area where the home is located.
• Pays at least 3 percent of the price from their own funds.
• Moves into the home as their primary residence within 60 days of closing.
• Uses a licensed California real estate agent or broker of their choice.
• Meets CalHFA’s underwriting standards. CalHFA can set credit-score and debt-to-income requirements in line with Fannie Mae, Freddie Mac or FHA rules.

Prop 37 is not limited to first-time buyers. The campaign described it as designed for renters, first-time buyers and working families, and that is the group most likely to use it. The measure itself does not require applicants to be first-time or first-generation buyers, unlike CalHFA’s existing Dream For All program. CalHFA must require homebuyer education for borrowers who would benefit from it, including first-time buyers.

Which Homes Qualify

The measure defines an eligible home broadly. It can be a stand-alone house, townhome, row house, condominium, manufactured home or other unit for one household. What matters is that it is new:

• A newly constructed home where the borrower is the first purchaser, or
• A condominium or other unit in a former nonresidential building converted to housing, again where the borrower is the first purchaser.

Resales do not qualify. The price cannot exceed 125 percent of the county’s one-unit conforming loan limit, which the Federal Housing Finance Agency publishes every year. In Los Angeles County, based on the 2026 limit, that puts the cap at about $1.56 million. The cap moves each year with the new conforming limits.

The Builder Side

Any builder’s homes can be eligible. Prop 37 also creates an optional “qualified builder option.” Builders who choose it agree to higher labor standards, drawn from the state’s existing streamlining laws. In return, their Prop 37 homes follow a modified construction-defect process, which gives the builder more room to repair issues before litigation. A builder who sells a home more than 25 percent above the price cap loses those modified rules for that home. Builders who do not opt in follow standard California construction-defect law.

What Is Still Undecided

• Timing. The measure takes effect once the election results are certified. CalHFA then has up to one year to launch the program. No loans are available yet.
• Rates and terms. CalHFA sets the interest rate, amortization and repayment terms, and lenders can charge only limited fees.
• Bond demand. The program depends on investors buying the bonds. The Legislative Analyst listed investor demand as one of the main unknowns.
• Reach. At the full 17 percent, $25 billion covers a finite number of loans. The Public Policy Institute of California estimated somewhere between roughly 113,000 and 560,000 buyers, depending on prices and loan sizes.
• Affordability of the payment. Analysts, including PPIC and the California Budget & Policy Center, noted that a down payment loan does not make the monthly payments any lower. Buyers still have to qualify for two loans at current interest rates.

Why It Matters for New Construction

Most down payment programs can be used on any home, new or existing. Prop 37 only works for homes no one has bought before. That ties the state’s largest down payment program to new supply: builders of for-sale homes gain a new group of buyers, and those buyers can only use the help on a home that adds to the housing stock.

For infill developers, the timing lines up with the state’s recent ownership laws. SB 684 and SB 1123 already allow up to ten fee-simple homes on qualifying lots, and AB 1751 will allow townhome projects of up to 150 homes from January 1, 2027. Those laws make more new for-sale homes possible to build, and Prop 37 helps buyers afford them.

Frequently Asked Questions

What is California Proposition 37?
Proposition 37, the California Middle-Class Homeownership and Family Home Construction Act of 2026, lets CalHFA issue up to $25 billion in revenue bonds and lend buyers up to 17% of the purchase price of a newly built home as a fixed-rate second mortgage. Voters approved it on November 3, 2026.

Did Proposition 37 pass?
Yes. The Associated Press called Proposition 37 as approved on November 4, 2026, with about 61% of counted votes in favor. Final results are certified after counting is complete.

Is Prop 37 only for first-time homebuyers?
No. The measure is aimed at renters and first-time buyers, but it does not require applicants to be first-time buyers. Applicants must have lived in California for at least a year, earn no more than 200% of area median income, and live in the home as their primary residence.

Is the Prop 37 money a grant?
No. It is a loan secured by a second mortgage, repaid monthly alongside the buyer’s first mortgage. CalHFA sets the interest rate and terms, and the measure requires the loans to be fixed-rate.

What homes qualify for Prop 37?
Newly built homes, townhomes, row houses, condominiums and manufactured homes where the buyer is the first purchaser, plus first sales of units converted from nonresidential buildings. The price cannot exceed 125% of the county’s one-unit conforming loan limit.

Not yet. CalHFA must launch the program no later than one year after the measure takes effect, and it still has to set rates, underwriting rules and approved lenders.
