The legislature plays a central and often decisive role in shaping how communities respond to homelessness and the shortage of affordable housing. As the branch of government responsible for crafting laws, setting budgets, and overseeing policy implementation, lawmakers directly influence the availability, affordability, and quality of housing across the country. Their decisions determine the scope of rental assistance programs, the scale of public housing investment, the fairness of tenant protections, and the resources available for emergency shelters and supportive services. However, legislative action on these issues is rarely straightforward. It requires navigating complex political dynamics, competing budgetary priorities, and deeply rooted structural challenges. Understanding the specific levers lawmakers can pull—and the obstacles they face—is essential for advocates, policymakers, and citizens alike.

Understanding the Legislative Role in Housing and Homelessness

The legislative branch operates at multiple levels—federal, state, and local—each with distinct responsibilities and authority. At the federal level, Congress authorizes and appropriates funding for major housing programs such as the Housing Choice Voucher Program (Section 8), public housing operating subsidies, the HOME Investment Partnerships Program, and the Continuum of Care program for homeless assistance. Federal legislation also sets the parameters for mortgage finance, fair housing enforcement, and tax incentives like the Low-Income Housing Tax Credit (LIHTC). At the state level, legislatures control land-use laws, allocate state funds for affordable housing trust funds, and can impose tenant protections that exceed federal minimums. Local city councils and county boards of supervisors often have the most direct impact on zoning, building codes, and the permitting process for new housing development.

Beyond funding and regulation, legislatures conduct oversight of executive agencies to ensure programs are implemented effectively. Hearings, reports, and investigations can expose inefficiencies, waste, or outright failures in homeless service delivery or housing production. Legislatures also have the power to commission studies, form task forces, and create dedicated bodies to coordinate cross-sector responses. In short, the legislative role is not limited to writing laws—it encompasses resource allocation, accountability, and long-term strategy.

Key Tools at the Legislature’s Disposal

Lawmakers have a toolkit of policy instruments to address homelessness and housing affordability. These include direct funding, tax incentives, regulatory reform, and tenant protections. Each tool has trade-offs in terms of cost, political feasibility, and effectiveness.

Direct Funding Appropriations

The most immediate way legislatures influence housing outcomes is through budget allocations. Annual budgets set the amount of money available for rental assistance vouchers, homeless shelters, rapid rehousing programs, and supportive services. For example, the federal fiscal year appropriations determine whether the Section 8 voucher program can serve additional families or be forced to maintain a waiting list. State legislatures can supplement federal funding with dedicated state funds, such as California’s $1 billion annual investment in homelessness response through the Homeless Housing, Assistance and Prevention (HHAP) program. Local legislatures can allocate general fund dollars to emergency rental assistance or mental health outreach teams.

Tax Incentives and Credits

Tax policy is a powerful but indirect tool. The Low-Income Housing Tax Credit (LIHTC) is the largest federal subsidy for affordable rental housing development, generating roughly 100,000 units per year. State legislatures can create their own tax credits—such as a state LIHTC supplement—to attract more private capital. Local property tax abatements or exemptions for affordable housing projects can lower development costs. Similarly, tax credits for developers who build in high-opportunity areas can encourage integration and reduce segregation.

Zoning and Land-Use Reform

One of the most contentious areas of legislative action is zoning reform. Local legislatures control how land can be used, including density limits, minimum lot sizes, building heights, and parking requirements. Reforms such as permitting accessory dwelling units (ADUs) by right upzoning near transit corridors, or eliminating single-family-only zoning can increase the supply of housing. Recent examples include Oregon’s statewide elimination of single-family zoning and California’s SB 9, which allows duplexes and lot splits in formerly single-family zones. Such reforms face strong opposition from homeowners concerned about neighborhood character and property values.

Tenant Protection Laws

Legislatures can enact laws that protect renters from displacement, discrimination, and unsafe conditions. Examples include rent stabilization or rent control ordinances, just-cause eviction requirements, source-of-income discrimination bans, and the right to legal counsel in eviction proceedings. These laws help prevent homelessness by stabilizing tenancies and giving tenants recourse against predatory landlords.

The Scope of the Crisis: Why Legislative Action Is Urgent

To appreciate the importance of legislative action, it helps to understand the scale of the problem. According to the U.S. Department of Housing and Urban Development’s 2023 Annual Homeless Assessment Report (AHAR), on a single night in January 2023, more than 653,000 people experienced homelessness across the United States—a record high since reporting began in 2007. Nearly 60 percent were in emergency shelters or transitional housing, but 40 percent were unsheltered, living on the streets, in cars, or in encampments. The crisis is especially acute among people of color, with Black Americans representing 12 percent of the total population but 40 percent of those experiencing homelessness.

On the affordability front, the National Low Income Housing Coalition’s annual “Out of Reach” report found that in 2023 a worker earning the federal minimum wage of $7.25 per hour would need to work 97 hours per week to afford a modest one-bedroom apartment at fair market rent. The severe shortage of rental units affordable to extremely low-income households—a gap of over 7 million units nationwide—means that millions of families spend more than half their income on housing, leaving them one financial shock away from homelessness.

These figures underscore why legislative intervention is not optional. Without robust funding, regulatory reforms, and protective laws, the homelessness and affordability crises will likely continue to worsen, particularly as wages stagnate and the cost of building materials and land rises.

Challenges and Political Dynamics

Legislatures face significant hurdles in passing effective housing legislation. The most pervasive challenge is political opposition. Opposition often comes from homeowner or neighborhood groups who fear that new affordable housing or homeless shelters will reduce property values, increase crime, or alter neighborhood character. This “NIMBY” (Not In My Backyard) sentiment can stall or kill even well-intentioned bills. For example, many proposals to upzone residential neighborhoods have faced fierce local resistance, requiring years of advocacy and compromise to pass narrow reforms.

Budget constraints are another persistent obstacle. Housing is expensive, and funding for vouchers, construction subsidies, and services must compete with education, healthcare, transportation, and public safety. At the federal level, discretionary spending caps and partisan gridlock often limit housing appropriations. At the state and local level, balanced budget requirements mean new investments must be offset by cuts elsewhere or tax increases, which are politically unpopular.

Economic factors also complicate legislative efforts. Rising construction costs, labor shortages, and high interest rates make it more expensive to build affordable housing, meaning that a fixed dollar amount buys fewer units. Inflation drives up operating costs for shelters and service providers. Legislatures must anticipate these dynamic conditions and build flexibility into their funding formulas and program designs.

Finally, measuring outcomes is difficult. Homelessness is caused by multiple overlapping factors—lack of affordable housing, mental health issues, substance use disorders, domestic violence, poverty, and systemic racism. Legislatures may pass bills but struggle to evaluate their impact because results take years to materialize, data is inconsistent across jurisdictions, and confounding variables abound. This can make it hard to maintain political support for long-term strategies as election cycles increase the pressure for quick wins.

Examples of Legislative Success

Despite the challenges, several jurisdictions have achieved meaningful progress through innovative legislative action. Examining these cases can provide a roadmap for other lawmakers.

California’s Inclusionary Housing and Streamlined Permitting

California has enacted a series of laws to promote affordable housing production. The state’s inclusionary housing ordinances require new market-rate developments to include a percentage of units affordable to low- or moderate-income households, often in exchange for density bonuses or other concessions. Additionally, recent legislation such as SB 35 (2017) and SB 423 (2023) streamlines the approval process for projects that meet certain affordable housing thresholds in jurisdictions that have not met their regional housing needs allocation (RHNA). These laws bypass some local zoning and environmental review hurdles, significantly reducing the time and cost of development. Between 2018 and 2023, California approved over 18,000 affordable units under SB 35 alone.

Rent Stabilization and Tenant Protections in Oregon

In 2019, Oregon became the first state to enact statewide rent control, capping annual rent increases at 7 percent plus inflation (with a maximum of 9 percent) and instituting just-cause eviction requirements. The law was a response to rapidly rising rents that were displacing low-income households in cities like Portland and Bend. While still early, initial studies suggest the law has tempered rent growth and reduced evictions without significant negative impacts on new construction starts. Oregon also passed a statewide fair housing law banning source-of-income discrimination, which helps voucher holders access rentals.

Housing First and Supportive Services in Salt Lake County

Local legislative bodies can also drive innovation. The Salt Lake County Council, in partnership with the state legislature, shifted funding toward Housing First models that prioritize permanent housing without preconditions of sobriety or employment. The county committed millions to building a new homeless resource center and expanding case management services. As a result, chronic homelessness in the county dropped by over 90 percent from 2005 to 2015, though it has since rebounded due to increased need and funding lags. The model shows that legislative investment in supportive housing can yield dramatic reductions in street homelessness.

New York’s Right to Counsel

In 2017, the New York City Council passed legislation guaranteeing free legal representation to low-income tenants facing eviction. This “Right to Counsel” law was the first of its kind in the nation. Research shows that tenants with attorneys are far more likely to avoid eviction and remain housed. The policy contributed to a significant decline in eviction filings and homelessness entries, demonstrating that legal protections can be a cost-effective preventive measure. Other cities, including San Francisco and Philadelphia, have since enacted similar laws.

Future Directions for Legislative Action

Moving forward, legislatures must adopt comprehensive, multi-year strategies that address both immediate needs and root causes. Housing affordability and homelessness cannot be solved by any single bill; they require sustained investment and a portfolio of reforms.

Scaling Up Rental Assistance

The most direct way to end homelessness for families and individuals is to ensure they have the resources to afford housing. Legislative bodies should expand voucher programs and create universal rental assistance for extremely low-income households. This would require significant increases in funding—for example, Congress could make the Section 8 program an entitlement, as some proposed legislation suggests. State and local governments can also create rental assistance programs targeted to their specific cost burdens.

Increasing Housing Supply Across the Income Spectrum

Zoning reform, permitting process improvements, and targeted subsidies can accelerate the production of new homes. Much of the recent legislative activity has focused on reducing barriers to development: eliminating minimum parking requirements, allowing multi-family housing in single-family zones, and implementing by-right approval for affordable projects. Continued efforts to pass such reforms at the state level can override local obstruction. Additionally, legislatures should increase funding for capital subsidies (like the National Housing Trust Fund) and preserve existing affordable units through anti-displacement measures.

Integrating Housing with Health and Social Services

Homelessness is often intertwined with mental illness, substance use disorders, and physical health conditions. Legislation that supports housing-first models with wrap-around services—including case management, healthcare, and employment assistance—can achieve better outcomes than housing alone. Funding for Medicaid demonstration waivers, 1115 waivers, and state mental health programs can be used to pay for these services. Legislatures can also mandate coordination between housing agencies, health departments, and social service providers.

Data Collection and Performance Accountability

Lawmakers should require robust data collection and reporting on homelessness counts, housing production, program outcomes, and client demographics. Transparent data helps identify effective investments and hold agencies accountable. Legislation such as the Homeless Data Integration Act (proposed at the federal level) and state-level mandates for by-name lists of homeless individuals can improve coordination and targeting of resources.

Addressing Root Causes: Economic Opportunity and Prevention

Preventing homelessness is far more cost-effective than responding to it. Legislatures can invest in eviction prevention programs, emergency rental assistance, workforce development, and income supports such as expanded child tax credits or basic income pilots. They can also raise the minimum wage, strengthen unemployment insurance, and ensure access to affordable healthcare—all of which reduce the risk of housing instability.

Conclusion

The legislature’s role in addressing homelessness and affordable housing is both powerful and complex. Through funding, regulation, tax policy, and oversight, lawmakers can either accelerate progress or reinforce the status quo. The crisis demands bold, sustained action—not incremental tinkering. While political obstacles are real, examples from California, Oregon, Salt Lake County, and New York City show that smart legislation can reduce homelessness, increase housing supply, and protect tenants. The path forward requires collaboration across levels of government, engagement with private and nonprofit sectors, and a commitment to evidence-based solutions. Legislatures that embrace this challenge can transform housing outcomes for millions of Americans.
