Affordable Housing Guarantee Act

Ordinance dedicating revenue from the existing real estate transfer tax on properties valued at $10 million or more exclusively to the protection, preservation, and production of affordable housing in San Francisco. It guarantees that funds cannot be diverted to other uses and creates new accountability requirements for how the money is spent.

WHEREAS, San Francisco is in a housing emergency—working families, seniors, teachers, nurses, and longtime residents are being forced out of the city they call home because there is simply not enough affordable housing, and without urgent action, that crisis will only deepen; and

WHEREAS, Only 7% of San Francisco's public employees can afford current market rate rents, 40% of workers don't reside in San Francisco, median income public employees would have a rent-burden of 59% if they lived in non-rent-controlled housing, and San Francisco would have to triple affordable housing production to meet the range of housing needs to fit workers' wages according to the 2021 San Francisco Labor Council's Housing Our Workers Report; and

WHEREAS, the City must build 82,069 new homes by 2031 to meet its identified housing need, and more than half—nearly 47,000—must be affordable to the low- and moderate-income San Franciscans who cannot survive in the private market without help; and

WHEREAS, more than 17,000 affordable homes are fully approved and ready to build, but sit idle because the public funding to break ground has not been secured—every year of delay means more families displaced, more seniors evicted, more workers priced out, and building costs increase; and

WHEREAS, at our current pace, San Francisco is building affordable housing six times slower than required—averaging fewer than 900 affordable units per year when the City needs nearly 5,825—and faces a staggering $26.6 billion funding gap over the next decade, with identified revenues covering less than 15 cents of every dollar needed; and

WHEREAS, San Francisco voters have already shown the way: the 2020 transfer tax on properties sold for $10 million or more has generated more than $200 million that prevented more than 25,000 evictions, removed hundreds of homes from the speculative market, and created over 550 new affordable homes, proving that when we spend this revenue on housing, it works; and

WHEREAS, this Measure does not raise taxes above rates already approved by the voters—it guarantees that money already collected from high-value property sales goes where San Franciscans intended it to go: protecting, preserving, and producing affordable housing for the people who make this city run;

THEREFORE, the People of the City and County of San Francisco do ordain as follows:

Section 1. Purpose.

The purposes of this Measure are to guarantee that the existing documentary transfer tax contributes to solving housing and homelessness in San Francisco by dedicating a portion of the existing revenue to specific housing and homelessness prevention strategies; to do so without raising taxes; to provide funding for new models of affordable and social housing; to prevent San Franciscans from falling into homelessness; to require mandatory audits and reporting of all monies raised and spent; and to ensure that these dedications and strategies cannot be changed without a vote of the people.

vi) Project funding may take the form of grants or loans, but shall not require the leveraging of additional forms of funding if such additional funding makes any of the conditions set forth in this subsection infeasible, or if funding precludes the future conversion of the property to tenant ownership.

(B) Emergency Rental Assistance. Funding for Emergency Rental Assistance may only be used for programs that provide short-term emergency funding to tenant households at risk of becoming homeless. Funds must stabilize low-income tenants at risk of losing their housing due to one-time economic shocks, and may cover the entirety of rent payments for up to 6 months. Priority eligibility shall be established for Lower Income Households.

Such households may be charged a rent commensurate with their current income levels.
