Proposition 37

Creates Loan Program for Middle-Income Buyers of Qualified New Homes

Creates Loan Program for Middle-Income Buyers of Qualified New Homes. Initiative Statute. Authorizes up to $25 billion in bonds to offer eligible buyers fixed-rate mortgages for up to 17% of the purchase price of a “qualified new home” (new construction or first sale of converted nonresidential property, priced below about $1 million-$1.5 million, depending on county, adjusted annually). Borrowers must be California residents for one year, occupy the home, earn less than twice the area’s median income, and pay at least 3% down. Requires that bonds be repaid by homeowners’ mortgage payments, not the State.

Summary

Proposition 37 is an initiative statute placed on the ballot by petition signatures. It adds a chapter to the Health and Safety Code that lets the California Housing Finance Agency (CalHFA) sell up to $25 billion in revenue bonds and use the money to make second mortgages, called middle-class homeownership loans.

A loan can cover up to 17 percent of the price of a qualified new home, which the measure limits to a newly built home or a home created from a nonresidential building converted to residential use, in both cases where the buyer is the first purchaser. A borrower must have been a California resident for at least one year, occupy the home as a primary residence, have family income no more than 200 percent of the area median income for the same family size, and pay at least 3 percent of the purchase price from a source other than a grant or borrowed money.

The homeowner's monthly payments on the loan are designed to repay the bonds and cover the program's administrative costs. The Legislative Analyst's estimate of the net state and local fiscal effect is no direct state or local costs. Developers can voluntarily join a qualified builder option that ties their homes to higher labor standards in exchange for different construction defect procedures.^S1^S2^S4^S7^S13

What a yes or no vote means

Yes means

A yes vote means the state would create a new homebuying assistance program. The state could sell up to $25 billion in revenue bonds to fund the program, and the bonds would be paid back by homeowners' payments on their home loans.^S1^S2^S3^S4^S13

No means

A no vote means the state would not be required to create a new homebuying assistance program. CalHFA would not receive the bond authority this measure would give it.^S2^S3^S4^S13

How it works

What kind of measure this is: Proposition 37 is a citizen-initiated state statute, not a legislative measure. It was submitted to the Attorney General on August 15, 2025, proponents had to collect 546,651 valid signatures to qualify it for the 2026 ballot, and the Secretary of State announced on April 21, 2026 that enough valid signatures had been verified to place it on the November 2026 ballot.^S13
Where the law goes: the measure adds Chapter 11.5 (commencing with Section 51515) to Part 3 of Division 31 of the Health and Safety Code and titles it the California Middle-Class Home Ownership and Family Home Construction Act of 2026. Its stated purposes include establishing middle-class home ownership loans for newly constructed single-family homes with no cost to taxpayers, expediting new single-family construction, protecting consumers from unfair lending practices, and encouraging investment in low-interest bonds, including lending that qualifies for Community Reinvestment Act credit.^S7
The money: the agency may issue and sell revenue bonds, and the principal amount of bonds issued and sold under the chapter may not exceed twenty-five billion dollars ($25,000,000,000), not counting refunding bonds. Every bond must carry a statement on its face that it is not a debt or liability or pledge of the faith and credit of the State of California other than the agency, and that it is payable solely from the funds provided for it.^S2^S7
The loan: each middle-class home ownership loan is secured by a secondary mortgage on the qualified new home, must be used solely to finance a portion of the purchase price, and may finance no more than 17 percent of the purchase price, which the Legislative Analyst describes as the part ordinarily covered by the buyer's down payment. The second mortgage is subordinate to the first mortgage, must be a fixed-rate loan, may not carry an early payment penalty, and the lender's origination fee may not exceed 0.5 percent of the loan or $290, whichever is greater, an amount the agency may adjust no more than once every two years.^S2^S7
Borrower eligibility: an applicant must be a California resident for at least one year before applying, must agree to occupy the home as a primary residence within 60 days of closing, must have family income no more than 200 percent of the area median income for a family of the same size in the county or metropolitan statistical area where the home is located, and must pay at least 3 percent of the purchase price from a source other than a grant or borrowed money. The Attorney General's title and summary states the same income rule as earning less than twice the area's median income, and states the one year residency and 3 percent down payment rules.^S1^S2^S7
Which homes count: a qualified new home is a newly constructed home, townhome, row house, condominium or manufactured home where the borrower is the first purchaser, or a condominium or other residential unit in a building that was a nonresidential structure and was retrofitted or repurposed for residential use where the borrower is the first purchaser. The maximum sales price may not exceed 125 percent of the conforming loan limit for a one-unit property in the county, as set out in the annual conforming loan limit report published by the Federal Housing Finance Agency. The Attorney General's title and summary describes that price cap as below about $1 million to $1.5 million depending on county, adjusted annually.^S1^S2^S7
What is left to CalHFA: the agency must implement the program no later than one year after the effective date of the act. The agency sets residency duration requirements for borrowers and the interest rates, amortization schedules, principal repayments, prepayment provisions and other payment terms on the loans, at levels necessary, to the greatest extent possible, to pay the principal, interest and other amounts due on the bonds plus the costs of administering the program. The Legislative Analyst says the agency is required to keep interest costs for homebuyers as low as possible and decides how much of the $25 billion to issue and over what period.^S2^S7
Underwriting and eligibility adjustments: the agency sets underwriting criteria and may adjust loan limits, minimum credit scores, additional credit verification and debt-to-income ratios to satisfy standards set by Fannie Mae, Freddie Mac or the Federal Housing Administration, so long as the criteria are consistent with the terms and purposes of the chapter. When issuing bonds, the agency is to set the manner, timing and geographic distribution of the bond sales, whether marketed regionally or statewide, in a way that minimizes interest costs and encourages broad investor participation.^S7
Consumer protections and oversight in the text: the agency must set consumer protection requirements for the lenders it contracts with, including limits on origination fees, a prohibition on early payment penalties and a requirement that the loans be fixed-rate. If an applicant's credit score does not qualify them for credit or the most favorable terms, the lender must let them voluntarily submit bank statements, paystubs, assets and rental payment history for cashflow underwriting. The applicant must retain a licensed California real estate agent or broker of their own choosing. A borrower may request a temporary hardship deferral of monthly interest payments under criteria the agency sets, and the agency must provide for an independent annual audit of the program.^S7
What developers get in exchange: the qualified builder option is voluntary. A developer certifies that construction will satisfy the qualified new home requirements, and the agency must confirm participation within 30 days. Participating builders are subject to specified labor and enforcement provisions of the Public Resources Code, are liable for certain labor law violations committed by their contractors and subcontractors, and a joint labor management cooperation committee may sue a contractor or subcontractor over unpaid wages, workers' compensation coverage or a lapsed contractor's license. In exchange, the Legislative Analyst says these developers are subject to different construction defect rules that generally aim to give developers more flexibility. If a builder sells a qualified new home for more than 25 percent over the maximum sales price, certain consumer protection provisions do not apply to that home.^S2^S7
Construction defect procedures for builder option homes: Title 7 of Part 2 of Division 2 of the Civil Code applies to qualified new homes, with modifications for homes built under the qualified builder option. Those modifications require a prelitigation notice to identify each homeowner and each alleged violation in each residence, allow the builder to communicate directly with a homeowner or claimant during the prelitigation process, allow the builder to obtain a written and voluntary release from the homeowner for claims related solely to repairs the builder completed, and allow a builder to move to dismiss if a court has stayed the action and the claimant has not taken action within 120 days. Attorney contingency fees in these homeowner actions may not exceed 30 percent of the total recovery unless a court approves a higher amount.^S2^S7
How the law can be changed later: the act says its statutory provisions may be amended by a statute that is passed by more than a 60 percent vote of the members of each house of the Legislature and signed by the Governor, so long as the amendment is consistent with and furthers the purposes of building more middle-class housing, protecting borrowers and expanding middle-class home ownership. The act is severable, is to be broadly construed, and states that if another measure authorizing revenue bonds to fund middle-class housing loans appears on the same statewide ballot, that measure is deemed to be in conflict and the one that receives more affirmative votes prevails in its entirety.^S7
What the program is limited to: the loans can only be used for the purchase price of a qualified new home, and a qualified new home must be newly constructed or a residential unit converted from a nonresidential building where the buyer is the first purchaser, so a purchase of an existing home that is not such a converted unit does not qualify. The Legislative Analyst also notes that all developers could build homes eligible for purchase under the program, whether or not they choose the qualified builder option.^S2^S7
Nonpartisan description of how it would work in practice: CalMatters reports that the agency would be able but not required to borrow up to $25 billion, that the loans could cover up to 17 percent of a home's purchase price, leaving a buyer with a cash down payment of 3 percent if paired with a typical mortgage, which CalMatters puts at $24,000 on an $800,000 home, that buyers would repay the loan in monthly installments to private lenders, that anyone earning up to twice the area's median income would be eligible, and that the measure was placed on the ballot by a coalition of real estate interests and labor unions.^S10
Who sponsored it: the California Budget and Policy Center describes Proposition 37 as a citizens' initiative spearheaded by former California Senate Majority Leader and Assembly Speaker Bob Hertzberg, who has said the main goal of the measure is to allow working families and their children to build wealth and remain in California. The Budget Center also notes that because the program would be financed with revenue bonds, which do not require voter approval, a similar program could have been enacted by the Legislature or established by CalHFA.^S11

Fiscal impact

The Legislative Analyst's summary of the estimate of net state and local government fiscal impact is: no direct state or local costs. The Legislative Analyst explains that because Proposition 37 uses the payments from homebuyers to repay bond investors, it would not result in direct state or local costs.

The analysis adds that a number of factors unknown at this time could affect the measure's scope and impact: the extent to which investors want to buy the bonds, how much the loans available under the program cost homebuyers compared with other down payment assistance options, and whether the program results in increased home construction and homebuying.

The measure caps bond principal at $25 billion and states that the bonds are payable solely from program funds and are not a debt or liability or pledge of the faith and credit of the state other than the agency. Nonpartisan analysis raises a further point about where the repayment money comes from: the California Budget and Policy Center says the bonds must be repaid from the proceeds of the program itself, meaning the principal and interest on the second mortgages, so the loans need to generate steady ongoing revenue to pay the debt, and it says the interest rate on the second mortgages would ultimately depend on the terms under which the bonds are issued and on market conditions, so the rate cannot be known before the vote.

The Budget Center also says that revenue bonds that finance second mortgages are riskier for investors because the first mortgage is repaid before the second if a homeowner defaults, which could lead investors to require a higher return and could raise the interest rate on the second mortgage above the roughly 6.5 percent conventional first mortgage rate it cites.

The League of Women Voters of California Education Fund states that if borrowers default on their loans, there may not be enough money to repay the bonds. Those two points are the Budget Center's and the League's analysis, not findings in the official fiscal estimate. The measure also requires an independent annual audit of the program.^S1^S2^S3^S4^S6^S7^S11^S12

Who benefits and who pays

Who benefits

Buyers who meet the residency, income, occupancy and down payment rules and who buy a qualified new home: they can receive a fixed-rate second mortgage of up to 17 percent of the purchase price. The measure does not require an applicant to be a first-time or first-generation home buyer, unlike some other state down payment assistance programs, and it does not require recipients to share equity gained in the home with the state.^S1^S2^S7^S11
Buyers who would otherwise pay for private mortgage insurance: the Budget Center says that combining the 17 percent assistance with the required 3 percent down payment reaches 20 percent of the home's purchase price and eliminates the need for private mortgage insurance.^S11
Applicants with thin or lower credit: the text requires the lender to let an applicant whose credit score does not qualify them for credit or the most favorable terms submit financial records, including bank statements, paystubs, verifiable assets and rental payment history, and to evaluate them using cashflow underwriting in an effort to qualify the applicant.^S7
Builders who choose the qualified builder option: they receive a letter from the agency confirming participation within 30 days, which the measure says may be relied on by the builder, prospective purchasers and construction lenders for marketing and financing the homes, and in exchange they are subject to different construction defect procedures that the Legislative Analyst says generally aim to provide more flexibility to developers. The Budget Center notes that joining the option makes a developer's homes automatically qualify for the program.^S2^S7^S11
Lenders: the agency may contract with banks, credit unions, trust companies and other lenders to originate or service the loans, and a lender may charge an origination fee of up to 0.5 percent of the loan or $290, whichever is greater. The measure also directs the agency to evaluate whether the program can be implemented so that lenders whose activities qualify for Community Reinvestment Act consideration can participate, and to do so if it can.^S7
Supporters' claims about who benefits: the argument in favor says the measure gives working and middle-class Californians a fair shot at homeownership, that it is designed for renters, first-time homebuyers and working families who earn too much to qualify for renter assistance but not enough to save a large down payment, and that it will accelerate construction of new homes and create thousands of good-paying jobs. The argument also says California has the second-worst homeownership rate in the nation and that with a statewide median home price now above $930,000, a traditional 20 percent down payment can require saving more than $186,000. These are the supporters' claims and figures as printed in the voter guide.^S5^S6
Organizations and people listed as supporters: the voter guide summary page lists United Nurses Associations of California, the California Conference of Carpenters and California State Treasurer Fiona Ma as supporters. The argument in favor is signed by Danny Curtin, director of the California Conference of Carpenters, by Fiona Ma as a board member of the California Housing Finance Agency, and by David West, chair of the California State Commanders Veterans Council, and it quotes State Controller Malia Cohen. CalMatters lists the California Democratic Party, Xavier Becerra, the California Association of Realtors, the California Conference of Carpenters and SEIU as supporters. CalMatters also reports the Sacramento Bee and the San Francisco Chronicle as media endorsements in favor.^S4^S5^S10^S13

Who pays

Borrowers, over the life of the loan: homeowners' monthly payments on the middle-class homeownership loan are designed to repay the bonds over time and cover the program's administrative costs. The Budget Center says participants are likely to pay the assistance back monthly as a fixed-rate second mortgage, in addition to their payments on a conventional first mortgage, and that the second mortgage rate could land above conventional first mortgage rates because the rate depends on the bond terms and market conditions set after the vote.^S2^S7^S11
Borrowers' cash at closing: an applicant must pay at least 3 percent of the purchase price from a source other than a grant or borrowed money, and the measure lets the agency adopt rules allowing a borrower to use the loan to pay closing costs if the agency decides that rule balances the interests of borrowers and bond investors. The Budget Center gives the examples of $15,000 on a $500,000 home and $21,000 on a $700,000 home, and notes that a 3 percent down payment could use most or all of what the median California household holds in checking and savings accounts, which it puts at just over $18,000 in 2025 dollars.^S7^S11
Bond investors, if borrowers default: the Budget Center says that because the second mortgage is repaid after the first if a homeowner defaults, investors in the bonds are more exposed to loss and may require a higher return. The League of Women Voters of California Education Fund states that if borrowers default on their loans, there may not be enough money to repay the bonds.^S11^S12
Not the state, under the official estimate and the bond terms: the Legislative Analyst says there are no direct state or local costs because homebuyer payments repay the bonds, and the text requires each bond to state on its face that it is not a debt or liability or pledge of the faith and credit of the state other than the agency and is payable solely from the funds provided for it.^S1^S2^S3^S7
Buyers of new homes can carry other costs of the home, which the Budget Center notes are not created by the program but are more common with new construction: homeowners association dues, Mello-Roos special tax assessments layered on property taxes in newly developed areas, and difficulty or added cost in obtaining home insurance in some areas.^S11
Critics' concerns about cost and risk, which are claims rather than official findings: no argument against the measure was submitted for the voter guide. The League of Women Voters of California Education Fund describes critic concerns that requiring only a 3 percent down payment may increase the risk of default if home values decline or borrowers face financial difficulty, that there may not be enough money to repay the bonds if borrowers default, and that some changes to construction defect rules could make it harder for homeowners to pursue claims against builders. CalMatters reports opponents arguing that state government should not be involved in the mortgage lending market, that the measure will not do much to address the underlying reasons housing in California is expensive, and that it helps more people buy homes only by allowing them to go into deeper debt.^S5^S10^S12

Key arguments

Supporters say the measure makes low-interest down payment assistance loans available to qualified California residents buying a newly built home with no cost to taxpayers, and that it is not a handout because homebuyers must qualify for a mortgage, meet income requirements, pay at least 3 percent down, occupy the home as their primary residence, make monthly payments and fully repay their loans. These are the supporters' claims as printed in the voter guide.^S5^S6
Supporters say California has the second-worst homeownership rate in the nation, that the statewide median home price now exceeds $930,000, and that a traditional 20 percent down payment can require saving over $186,000. These are the supporters' figures as printed in the voter guide.^S5^S6
Supporters say the measure will help accelerate construction of new homes, create thousands of good-paying jobs and generate economic investment, and that expanding the housing supply helps workers and families stay in California and build equity.^S5^S6
Supporters say the loans are funded by private bond investors and repaid by home borrowers rather than taxpayers, and the argument quotes State Controller Malia Cohen making that point about state revenue bonds.^S5^S6
Supporters say the measure includes fiscal accountability and transparency requirements, construction accountability standards and annual audits detailing the status of loans made and the fund's financial condition, and they list consumer benefits including below-market fixed-rate loans, protections from unfair lending practices, strict limits on lender fees and no penalty for early repayment.^S5^S6
Supporters say the measure has broad bipartisan support from Democrats and Republicans, labor and businesses, construction workers, taxpayer and housing advocates, veterans, the California Teachers Association and the United Nurses Association of California.^S5^S6
Money reported on the support side: the Secretary of State's contribution totals page for this measure reports one committee formed for the measure, YES ON 37, CALIFORNIA HOMEOWNERSHIP (committee ID 1481256), with a total of $19,618,927 in reported contributions through 10/06/2026. The Fair Political Practices Commission's top 10 contributors list for the November 2026 general election, last modified October 14, 2026, reports $30,882,858.27 in top aggregated contributions in support, and it also lists a second supporting committee, Homeownership for Families, sponsored by California Association of Realtors (committee ID 1400190), with $7,000,000 from the California Association of Realtors Issues Mobilization PAC and the National Association of Realtors. The two figures are different measures of the money: the Secretary of State total is the committee's reported contributions through 10/06/2026, while the FPPC figure is the total donated by the top contributors that list identifies.^S8^S9

Key arguments

No argument against Proposition 37 was submitted for the official voter guide. The arguments page states that no argument against Proposition 37 was submitted, and the summary page lists no opponents in its opponents field.^S4^S5
CalMatters reports that some opponents argue state government should not be involved in the mortgage lending market and that the measure will not do much to address the underlying reasons housing in California is so expensive, while others note that it would help more people buy homes but only by allowing them to go into even deeper debt. These are the opponents' arguments as CalMatters reports them.^S10
Who is listed as opposing: CalMatters lists Reform California and the League of Women Voters as opponents, and the Institute of Governmental Studies lists the same two and says it has not located an official campaign website in opposition to the measure. CalMatters also reports the San Diego Union-Tribune and the Orange County Tribune as media endorsements against.^S10^S13
Critics' concerns as summarized by the League of Women Voters of California Education Fund: the measure could encourage new housing farther from existing communities and services, requiring only a 3 percent down payment may increase risks of default if home values decline or borrowers experience financial difficulties, if borrowers default there may not be enough money to repay the bonds, and some changes to construction-defect rules could make it more difficult for homeowners to pursue claims against builders. The League also states that no official opposition campaign was identified in the official voter guide.^S12
Nonpartisan analysis of what the assistance would cost a borrower, which the Budget Center presents as a caution rather than an endorsement of either side: it says the assistance is provided as a loan that recipients are likely to pay back monthly as a fixed-rate second mortgage, that the second mortgage rate would ultimately depend on the bond terms and market conditions and cannot be known before the vote, that the rate could land above the roughly 6.5 percent conventional first mortgage rate it cites, and that the monthly repayment costs could erode much of the benefit the down payment assistance was meant to provide. The Budget Center also says the benefits may skew toward eligible families with greater financial resources and that the new-construction requirement could direct housing demand toward suburban and exurban areas.^S11
No committee money on the oppose side: the Secretary of State's contribution totals page for this measure states that no committees were identified as opposing it as of 10/06/2026, so no opposing committee total is reported. The Fair Political Practices Commission's top 10 contributors list for the November 2026 general election states that no committee opposing this ballot measure raised enough money to reach the reporting threshold for its list, which covers committees that raised at least $1,000,000.^S8^S9

How it could affect your household

Household type	Effect	Explanation	Confidence
Homeowner	Neutral	The measure creates no tax, fee or assessment that a current homeowner pays, and its bonds are repaid from borrowers' payments rather than from the state General Fund. A homeowner who is not buying a newly built home is not directly affected. A homeowner who does buy a qualified new home as a primary residence could use the program, because the measure does not limit eligibility to first-time buyers, but the assistance is a second mortgage that must be repaid monthly on top of a first mortgage.^S1^S2^S7^S11	Medium confidence
Renter	Mixed	A renter who meets the residency and income limits and can put 3 percent down could use the program to buy a newly built home, and the measure is not limited to first-time buyers. The assistance is limited to new construction or converted nonresidential units, so a renter buying an existing home could not use it, and the assistance is a loan repaid monthly as a second mortgage rather than a grant. The Budget Center says the monthly repayment costs could erode much of the benefit and that the benefits may skew toward eligible families with greater financial resources, and it gives $15,000 on a $500,000 home and $21,000 on a $700,000 home as examples of the required 3 percent down payment.^S1^S2^S7^S11	Medium confidence
W-2 earner ($100k to $250k)	Mixed	This household is likely inside the income limit, which is 200 percent of area median income and, in the Budget Center's examples, reaches $166,800 for a family of four in Madera County and $375,800 in Santa Clara County, so a household at this income could apply to buy a qualified new home. The measure creates no new tax on this household. What is not settled is the cost: the terms of the second mortgage, including its interest rate, are set by CalHFA after the vote and depend on the bond sale and market conditions, and the Budget Center says that rate could exceed conventional first mortgage rates, so the monthly cost of the assistance is unknown before the vote.^S1^S2^S7^S11	Medium confidence
High earner (over $1M)	Neutral	The measure creates no new tax, surcharge or bracket and does not change personal income tax rules, so it does not directly change this taxpayer's state taxes. Eligibility is limited to family income no more than 200 percent of area median income, which the Budget Center's examples put at $375,800 for a family of four in Santa Clara County, the highest example in its analysis, so a household earning over $1 million would be above the income limit and would not be able to use the program.^S1^S2^S7^S11	High confidence
Small business owner	Mixed	For a construction or real estate business the measure creates new work and new rules: developers may voluntarily join the qualified builder option, which brings confirmation of participation, higher labor standards and different construction defect procedures, while lenders that originate the loans may charge an origination fee of no more than 0.5 percent or $290. A small business outside housing gets no new tax or fee from the measure. The Budget Center notes the measure could steer housing demand toward newly built homes, which affects builders and realtors more than other businesses, and that builders who join the option face the labor standards the text sets out.^S2^S7^S11	Medium confidence
Retiree	Unclear	The measure creates no tax on retirement income, Social Security or pensions and takes nothing away from retirees. It does not restrict eligibility to first-time buyers, so a retiree within the income limit who buys a qualified new home could use the program, but the assistance must be repaid monthly as a fixed-rate second mortgage and the measure includes a hardship deferral of monthly interest payments that a borrower may request, which suggests payments are expected. The final terms, including the interest rate and the monthly payment, are set by CalHFA after the vote, so the direct cost to a retiree who used the program cannot be stated before the election.^S2^S7^S11	Low confidence
Local government services user	Neutral	The Legislative Analyst's estimate of net state and local government fiscal impact is no direct state or local costs, because homebuyer payments repay the bond investors, and the bonds are payable solely from program funds rather than from the state's General Fund or local budgets. The measure does not change the taxes or fees that fund state and local services. The Legislative Analyst says other effects are unknown and depend on investor demand for the bonds, how these loans compare in cost with other down payment assistance, and whether the program increases home construction and homebuying. The Budget Center raises indirect considerations about where new housing would be built and about added costs of new-construction homes such as Mello-Roos assessments that fund local infrastructure, but those are its analysis rather than findings of the official estimate.^S1^S2^S3^S6^S7^S11	Medium confidence

Tradeoffs

No direct taxpayer cost against repayment risk: the Legislative Analyst says the measure has no direct state or local costs because homebuyer payments repay the bond investors, and the bond face statement says the bonds are not a debt or liability of the state other than the agency. On the other side, the Budget Center says the bonds must be repaid from the program's own proceeds and that revenue bonds backed by second mortgages are riskier for investors because the first mortgage is paid first if a homeowner defaults, and the League of Women Voters of California Education Fund states that if borrowers default there may not be enough money to repay the bonds.^S1^S2^S7^S11^S12
Cheaper than saving a full down payment against a new monthly payment: supporters say the loans carry below-market interest and let buyers in with 3 percent down, and the Budget Center says the combination of 17 percent assistance and 3 percent down reaches 20 percent and removes the need for private mortgage insurance. The same analysis says the assistance is a loan likely repaid monthly on top of a first mortgage, that the rate could exceed conventional first mortgage rates, and that the repayments could erode much of the benefit.^S5^S6^S11
New construction only: supporters say limiting the assistance to newly built homes will accelerate construction, add supply and create jobs. The Budget Center says that restriction could push middle-class housing farther from job centers and toward land that is environmentally sensitive, wildfire prone or agricultural, and that new homes are more likely to carry homeowners association dues, Mello-Roos assessments and insurance difficulties, which could undercut the affordability gain.^S5^S6^S11
Broad eligibility against reaching those who need it most: the income limit is 200 percent of area median income and there is no first-time buyer requirement, which the measure's supporters present as help for working and middle-class families. The Budget Center says that broad eligibility could mean the assistance largely benefits families toward the higher end of the range, notes that the required 3 percent down payment could still be out of reach for many Californians, and says the design could reinforce existing racial and ethnic gaps in homeownership.^S5^S11
Construction defect rules: builders who take the qualified builder option meet higher labor standards and, in exchange, more flexible construction defect procedures, such as direct communication with homeowners during the prelitigation process and a written release for completed repairs. The League of Women Voters of California Education Fund states that some changes to construction defect rules could make it harder for homeowners to pursue claims against builders, and the measure provides that a builder who sells a home more than 25 percent above the maximum sales price does not get certain of those protections for that home.^S7^S12
Terms left to the agency: the measure says the agency must keep interest costs for homebuyers as low as possible but does not set a rate, a loan limit in dollars or a schedule for bond sales beyond the $25 billion cap and a one year implementation deadline, so the cost to borrowers and the pace of the program depend on decisions made after the election. The Budget Center makes the same point about the interest rate being unknowable before the vote.^S2^S7^S11
Money on one side only: the Secretary of State reports $19,618,927 in contributions to the supporting committee through 10/06/2026, while no committee was identified as opposing the measure and no argument against it was submitted for the voter guide. The Fair Political Practices Commission's list reports $30,882,858.27 in top aggregated contributions in support and no opposing committee above its $1,000,000 reporting threshold. Reform California and the League of Women Voters are listed as opponents without a committee, so the arguments against the measure that appear in public come from nonpartisan analysis and press reports rather than from a funded campaign.^S4^S5^S8^S9^S10^S11^S12^S13
