Rebuilding the American Dream: Policy Approaches to
Increasing Housing Supply in the U.S.
A strong U.S. middle class depends on families having the opportunity to buy a home, build
wealth and pass it on to the next generation. Research has shown that when low-income
families move to stable homes in neighborhoods with a range of family incomes, their young
children’s future earnings and life outcomes improve significantly. Broad access to affordable
and stable housing helps ensure Americans’ economic well-being and mobility. However, the
current housing shortage limits Americans’ ability to access this next step.
Currently, middle-income households are struggling to secure affordable housing and
homeownership is out of reach for many Americans. Rents have also been climbing over the
past decade and many lower-income families are being priced out of their current
neighborhoods. Meanwhile, these families are blocked from renting in higher income
neighborhoods due to absence of smaller, more affordable housing options and housing
discrimination.
The United States has arrived at this moment after decades of exclusionary zoning and land use
regulations that have limited housing choice and supply. Fortunately, states and localities across
the country have been actively working to reverse this history, taking action to modernize their
land use and zoning rules and enact new policies that build more housing that is accessible to a
wider array of income levels. In addition to more better paying jobs and full funding for housing
vouchers, which are vital to ensuring stable housing, these efforts to increase supply can help to
relieve economic and housing capacity pressures from the housing shortage. Policy changes
occurring across the country can serve as test cases for enhancing housing affordability and
provide guidance for federal efforts to increase housing stock, while enhancing economic
freedom.

Removing Barriers to Housing Supply Can Enhance Affordability
Increasing housing supply to meet demand can help reduce growth in prices.
The U.S. is facing a housing affordability crisis driven in large part by inadequate housing
supply. After the housing market collapse in 2008, new housing supply for single- and multi-unit
buildings declined. Yet, as demand recovered, supply did not. Building on this crisis, in the wake
of the pandemic the number of housing units available for purchase or for rent fell to near record
lows. In 2021, Freddie Mac estimated that the shortage of newly-built homes was about 3.8
million, noting that entry-level starter home construction has fallen since the 1970s.
The housing shortage is impacting affordability for renters and prospective homeowners alike.
For example, in 2022 those earning at or below U.S. median income could only afford to own 20
percent of all homes on the market, down from about 50 percent in in 2016. Additionally, as the
Council of Economic advisors wrote in 2021, “across the country, more than 10 million renters
(one in four) pay more than half of their income on rent, and nearly half (47 percent) spend over
the recommended 30 percent of their income on rent and utilities.” Research has shown that an
increase in supply of housing stock can alleviate this upward pressure on home prices and help
ensure that more affordable options are available to average Americans.
Zoning and land use regulations are making it more difficult to increase housing supply.
While increasing housing stock can help relieve the affordability crisis, zoning and land use
regulations that mandate how land can be developed often actively prevent much-needed new
housing construction. Many of these laws, which are implemented at the local or state level,

directly restrict the number of units that a structure can have or limit the size of the structures
through restrictions on square-footage, lot size, or height. These rules often mean that a single-
detached home is the only type of housing that is legal to build in these areas. Meanwhile, other
zoning and land use laws block construction of new housing altogether.
Many of these laws limit choice in housing type and location by barring construction of more
affordable options like townhouses, duplexes, and smaller apartment buildings in favor of
standalone single-family houses on larger lots. These mid-sized buildings, which can house
between two to four families on a single lot, are still rarely built with developers mainly favoring
single-detached houses or to a lesser extent, larger apartment buildings. Such restrictions on
housing choice continue to place limits on who can afford to rent or purchase a home based on
their income level.
Zoning and Land Use Regulations Are Maintaining Regressive
Barriers to Housing Choice and Stability
While local and state laws currently govern zoning and land use, the federal government
led in shaping exclusionary standards that are common throughout the country.
Historically, the federal government has given local governments the authority to set land use
rules, while also acting as a guiding hand for what land use policy should look like throughout
the country. Starting in the 1910s, an initial wave of state legislation gave municipalities zoning
authority and established local planning boards. Then in the 1920s, the Department of
Commerce (DOC) under Secretary Herbert Hoover issued guidance for legislative language for
states to establish zoning authorities for general municipalities and cities. Researchers note that
the DOC drafted this legislative language in order to provide a framework that minimized legal
challenges to municipal zoning. Over time, all 50 states, and DC, adopted a form of these

guidelines, and the American Planning Association found that many states continue to use laws
based on these models today.
Exclusionary zoning limited housing supply and left a legacy of unequal opportunity.
Following these actions, restrictions on where people could live and the types of housing they
could live in, laid the groundwork for the housing challenges the country faces today. For
example, the boom in single-family detached housing developments in the 1940s, 50s and 60s
coincided with a massive increase in homeownership. Yet the neighborhoods developed in this
era were initially closed to families of color. Federal agencies refused to provide mortgage
insurance and financing for homes in neighborhoods where primarily families of color lived,
despite providing an abundance of such assistance to other families across the United States.
Restrictive covenants also barred many families from homeownership, and real estate
companies’ discriminatory practices further limited housing choice.
While the Fair Housing Act outlawed many of these discriminatory practices in 1968, land use
and zoning restrictions perpetuated inequality in housing access while maintaining the status
quo of neighborhood segregation. For example, municipal governments enacted laws to rezone
multiple residential neighborhoods for commercial use or construction of new highways, projects
which were also funded by the federal government. These neighborhoods were primarily home
to lower- and middle-income families and communities of color. Meanwhile, wealthier localities
blocked new housing construction in neighborhoods with single-detached homes—the primary
form of housing at the time—with new zoning and land use regulations. Taken together, such
practices, through their legacy or continued use have played a large role in preventing economic
and racial integration in many American neighborhoods, and in creating additional barriers to
housing stability for more Americans.
Land use and zoning restrictions continue to limit housing stock and economic freedom.
Restrictions that limit where people can live have been found to harm the wider economy. Often,
lower-income workers live further from job centers, in large part because housing in job-rich
areas is too expensive for them to afford. In addition to impacting one’s job and income
prospects, a person’s neighborhood often impacts their academic achievement and health, as
well as that of their families and future generations. Studies have also linked restrictions on
housing choice to lower levels of U.S. GDP.
Racial segregation by neighborhood also remains a reality in the United States. For example,
research has shown that due to continued exclusionary zoning—which influences who can
easily attend certain local public schools—school segregation today mirrors levels seen in 1968,
the year that Congress passed the Fair Housing Act.
States and localities have started to enact laws that can help undo the harms of zoning and land
use regulations, and build the foundation for more inclusive and affordable neighborhoods.
These initial efforts can serve as models for future work across the United States.

State and Local Efforts Towards Zoning Reform Can Help Reshape the
U.S. Housing Market
Despite the challenges presented by restrictive zoning policies, many states and localities are passing laws meant
to modernize housing regulations and increase the number of housing options available to residents. Below are
three examples of policy changes that take aim at the negative effects of past zoning rules.
Oregon: Reforming State Law to Increase Local
Government Uptake of Zoning Reform
In 2019, Oregon became the first state to require that
nearly all cities and towns change their zoning codes to
allow for a wide range of housing options for families. The
new law—House Bill (H.B.) 2001—requires every city with
10,000 people or more, as well as every city in the Portland
metropolitan area with 1,000 or more people, to amend
their zoning codes to allow for townhouses, duplexes, or
other types of adjoined housing. About 70% of all residents
of the state reside in an area that this law impacts.
Governor Tina Kotek—who championed the bill during her
time as Oregon Speaker of the House—explained that the
law was meant to re-establish economically-diverse
neighborhoods that were ubiquitous in Oregon in the past.
In contrast, at the time of H.B. 2001’s passage, 77% of land
in Oregon zoned for residential housing was restricted to
single-detached houses. The state legislature will also be
providing funding to assist localities in implementing the
new zoning regulations to align with H.B. 2001. Governor
Kotek has previously emphasized the impact of the law will
be gradual, taking place over up to 20 years.
California: Using New and Existing Law to Expand
Variety in Housing Structures, and Grow Supply
In 2021, Governor Gavin Newsom signed Senate Bill (S.B.)
9 into law, which legalized more housing choice throughout
California. Homeowners now have more freedom and
flexibility when it comes to how they use their property. The
new law requires a simpler local government approval
process for conversion of single-detached homes into
duplexes, splitting a lot in two in order to build two smaller
homes or duplexes, or adding a small accessory dwelling
unit (ADU) to their land. This law led to tens of thousands
of ADUs being permitted across the state. ADUs are often
smaller attached or detached residential units that are
secondary structures on a tract of land, and contain
sufficient facilities for a resident to live independently.
On the other hand, Californians have been much less likely
to use S.B. 9’s authority to convert their homes or divide
their lots. This authority had only been used 282 times
about a year after the bill’s passage, despite estimates that
as many as 700,000 homes could be built under this new
law.
In the past year, the Newsom administration and
developers have started using existing legislative language
to increase multi-unit dwelling construction more broadly,
as well as counteract select localities’ efforts to circumvent
S.B. 9’s requirements. A statute known as the “builder’s
remedy” lets developers go around local zoning codes in
areas where local governments failed to lay out a plan for
housing production to meet local needs. In these localities,
developers can move forward with projects where either all
of the units are priced at levels that are affordable for
middle-income households, or at least 20% of the units are
affordable for lower-income households. This has led
developers in wealthy areas like Santa Monica and Beverly
Hills to use the law’s protection to apply for or initiate
affordable housing projects that could have otherwise been
blocked by local zoning rules.
Albuquerque, New Mexico: Increasing Supply through
Building Conversions and ADU Construction
In July 2023, the city of Albuquerque adopted ADU and
building conversion reforms. The changes will allow certain
properties zoned for single-family home construction to
build ADUs—also referred to as “casitas”—on their
properties, which alone impacts up to 68% of all zoned
properties in the city. Additionally, they provide for
conversions of certain non-residential developments to
multi-family unit dwellings, which can facilitate conversion
of former hotels to residential units. The city has also
considered other proposals to meet housing demand,
which included eliminating maximum building heights,
allowing single-detached homes to be converted to
duplexes, and reducing parking requirements for multi-unit
dwellings.

New Models for Financing Can Help Increase Affordable Housing
Construction
Removing regulations alone will not solve the housing crisis.
While removal of zoning restrictions will help with the effort to increase the supply of housing,
the market will not sufficiently increase the number of affordable housing units without additional
government intervention. For example, developers may be drawn to developing in primarily
higher-income areas, as they will be able to derive higher profits from units built on land with
higher property values, and people will be willing to pay more to live in these neighborhoods.
Moreover, new buildings in lower-income areas could lead to unaffordable prices for current
residents, who are likely living in older housing stock that is cheaper than newly-constructed
housing. Absent any other policy changes, this could mean that new, wealthier residents would
move into the new units, while lower-income renters would still face a housing shortage and the
potential for displacement. Rising home values would also increase wealth for current
homeowners, but renters could be harmed under these circumstances.
There is a growing recognition that governments need to do more to ensure that enough newly
constructed housing is affordable to the lowest-income families. The Low-Income Housing Tax
Credit (LIHTC) is a primary way that federal and state governments help finance new buildings
with affordable rental units, but the program is oversubscribed and in need of reform to ensure it
reaches those most in need. The bipartisan Affordable Housing Credit Improvement Act would
increase the number of available credits to better meet demand while changing the program
rules to make sure that more units were built to serve Tribal communities, rural areas, and other
at-risk and underserved groups. State-level requirements for a minimum threshold of affordable
housing per municipality, as is required in Massachusetts, could also be useful among other
tools used to increase the number of affordable units. Without these mechanisms, prices for
housing available to low-income families will likely remain elevated.
When coupled with zoning reform, changes to government funding mechanisms can help
enhance lower-income families’ access to housing in higher-income areas.
Reforms to government-financed affordable housing development programs can increase
housing choice for low-income families. Historically, public housing investment has concentrated
affordable housing in areas of high poverty, limiting low-income families’ choice of where to live.
More recent federal programs—aimed at reducing residential poverty concentration—then
replaced low-income housing with mixed-income housing and led to low-income families’
displacement. Some housing advocates also argue that LIHTC’s current structure encourages
low-income housing development primarily in low-income areas, forgoing an opportunity to
provide lower-income families greater access to the economic and environmental advantages
seen in higher-income areas. Housing vouchers enhance families’ housing choice, and
government efforts to supply affordable housing in areas of various income levels contributes to
this end. While the following section discusses models for public financing of affordable housing
stock, ensuring families’ housing choice is key to equitable affordable housing development.

State and Local Models for Financing Increase Affordable Housing Stock
In recognition of the need for additional affordable housing supply, state and local governments are
exploring financing incentives to increase the stock of housing that is affordable to low- and middle-
income families without demand-side subsidies. Below are a few promising case studies for these efforts.
Maryland: Multiple Approaches to Affordability
The Housing Production Fund: Creating a Public
Alternative to Private Housing Investment
In 2021, officials in Montgomery County, Maryland created
a Housing Production Fund (HPF) to finance construction
of mixed-income housing. The county’s Housing
Opportunities Commission (HOC) seeded the fund with
$100 million in bond financing that the fund lends out to
developers to help cover the costs of new construction. The
HOC can compete with private investors because it can
afford to receive lower returns from ownership shares in the
property, as well as offer lower interest rates on loans, than
what private equity firms or other investors would demand.
In exchange, the HOC requires developers entering into
this agreement to set aside at least 20% of the new units
for families earning at or below 50% Area Median Income
(AMI), and at least 10% of the units for those earning up to
70% of AMI. This model allows private developers to make
a profit, while the HOC retains an ownership stake that
supports its goal of keeping people housed at affordable
rates. Importantly, it can also maintain the pace of new
construction when interest rates are high as they are now,
by ensuring that developers can keep their financing costs
down in exchange for creating affordable housing for more
middle-class families. Developers recently completed one
of the first projects that utilized the HPF: a 268-unit
building, in which 25% of the units will be affordable to
tenants with income levels at 50% AMI.
The Affordable Housing Opportunity Fund: Supporting
Affordable Rent Levels for Tenants
In addition to the HPF, in 2022 the County created a $14
million Affordable Housing Opportunity Fund (AHOF) to
make short-term loans to prospective building owners. The
fund aims to support affordable housing developers in
building purchases, to maintain affordable rents for existing
affordable units. The short-term loans are meant to support
rapid purchases of existing buildings that may otherwise be
sold to landlords who could hike rents and make the units
unaffordable.
New Mexico: Investing in Local Affordable Housing
Trust Funds
Local governments across New Mexico have also been
leading efforts to finance affordable housing stock. For
example, in November of 2023, voters in Santa Fe
approved a ballot measure instituting a tax on the sale of
homes over $1 million, with proceeds directed to the city’s
Affordable Housing Trust Fund (AHTF), tasked with
meeting the city’s affordable housing needs. The tax—also
referred to as the “Mansion Tax” would apply only to the
value of a property above the $1 million threshold, at a rate
of 3%. The city has estimated that the measure will
generate approximately $6 million each year, providing the
fund with a substantive dedicated revenue source. In
2022, voters in the City of Las Cruces also approved the
issuance of a $6 million general obligation bond to fund its
AHTF, which was established in 2010 and previously relied
on limited capital infusions from the city’s general funds.
The city previously estimated that the initial $6 million
investment could help leverage more than $36 million in
funding from state, federal, and private sources, to create
an additional 175 affordable housing units.
Maine: Enhancing Affordability in Rural Areas
Maine’s Rural Affordable Housing Rental Program,
launched in 2022 using $20 million in funds from the
American Rescue Plan and MaineHousing bond issues,
uses forgivable loans to incentivize affordable housing
development in rural areas that might otherwise not draw
new construction. Eligible applicants include public
housing authorities, as well as nonprofit and for-profit
developers, and the loans they receive can be forgiven for
up to $185,000 per unit. The program targets rural areas
for projects and is intended to help build 115 new units in
rural Maine with existing funds. All units that benefit from
the program must be leased to those making at or under
80% AMI, and any loan recipients must limit rent increases
on supported units for the next 45 years. The program has
already closed applications due to significant uptake,
though Governor Janet Mills’ recently passed FY 2024-
2025 budget dedicated up to $35 million to the program to
support continued operations.

The Biden Administration Is Taking Important Steps to Increase
Housing Supply
Alongside the state and local efforts highlighted above, the Biden administration has advanced
efforts to alter current land use laws and zoning regulations to ensure more Americans can afford a
home that promotes their economic and social well-being. Specifically, the administration’s Housing
Supply Action Plan includes multiple programs that support housing construction. For example, the
Pathways to Removing Obstacles to Housing (PRO Housing) program provides a total of $85 million
in grants to localities that are taking steps to remove regulatory barriers for affordable housing
construction. The FHA has also published a proposal to facilitate ADU financing and HUD has
announced policy changes that will allow more, larger loans to qualify for the LIHTC program.
In addition, the American Rescue Plan’s (ARP) State and Local Fiscal Recovery Funds (SLFRF) has
helped to stimulate affordable housing construction and support housing stability. Between July 2022
and April 2023, state and local allocations towards housing construction, preservation and stability
grew by 29%. The HOME program, which received $5 billion from the ARP to support affordable
housing construction, rental assistance, and supportive housing services, is anticipated to increase
affordable housing stock across the country by at least 20,000 units.
The administration is also working to support states and localities in office-to-residential conversion.
It has created a $27 billion Greenhouse Gas Reduction Fund under the Inflation Reduction Act to,
among other things, construct new buildings with zero emissions and support converting buildings
from commercial to residential structures. Moreover, the administration has announced their plan to
fund office-to-residential conversion research, as well as the creation of a guide implementing cost-
effective conversion projects for states and localities.
Conclusion
States and localities across the country are working to reverse the consequences of existing zoning
restrictions and provide more funding for affordable housing construction and maintenance.
Congress can support these efforts by funding land use reform implementation, financing state and
local efforts to build more affordable housing and investing more federal funds in new construction.
The federal government is also well-positioned to help municipalities share information and ideas on
the best ways to propose, pass, and implement zoning and land use reform. The federal government
can also consider issuing a new example of legislative language that states and localities could use
to undo the exclusionary models created in the 1920s and create more housing for all Americans.
No one program or policy will resolve the nation’s housing crisis on its own. Coordination between
state and local governments and the federal government can help ensure the array of policies aimed
at increasing the supply of affordable housing for all Americans will be successful.
