The relationship between state and local governments is a defining feature of American federalism, yet it is often misunderstood. While the U.S. Constitution grants sovereignty to states, local governments—counties, municipalities, townships, and special districts—derive their authority entirely from the states. This arrangement creates a dynamic where states hold the ultimate legal power, but local governments exercise considerable discretion over the services that directly affect residents’ daily lives. Understanding who is in charge requires examining the legal doctrines, fiscal arrangements, and real-world interactions that shape this partnership.

Overview of State and Local Governments

State governments are sovereign entities within the federal system. They possess plenary power—meaning they can act on any matter not prohibited by the U.S. Constitution or their own state constitution. Local governments, in contrast, are “creatures of the state.” Their existence, structure, and authority are defined by state constitutions, statutes, and charters. This fundamental asymmetry sets the stage for the perpetual negotiation of power between the two levels.

State Government Powers and Responsibilities

State governments oversee broad functions that affect the entire state population:

  • Lawmaking and Regulation: Enacting criminal codes, business regulations, environmental standards, and professional licensing requirements.
  • Budget and Finance: Raising revenue through state income and sales taxes, allocating funds for education, health care, transportation, and corrections.
  • Education Systems: Setting curriculum standards, teacher certification requirements, and funding formulas for K–12 public schools and state universities.
  • Public Safety and Health: Managing state police, emergency management, and statewide health initiatives such as Medicaid administration.

Local Government Powers and Responsibilities

Local governments operate at the grassroots level, tailoring services to community needs:

  • Service Delivery: Providing trash collection, water and sewer services, public transit, parks, and libraries.
  • Land Use Planning: Zoning ordinances, building codes, and subdivision regulations that shape development.
  • Local Law Enforcement and Courts: Municipal police departments, county sheriffs, and local judiciary systems for minor offenses.
  • Election Administration: Managing voter registration, polling places, and ballot counting for local, state, and federal elections.

The U.S. Constitution does not mention local governments. Instead, it reserves powers not delegated to the federal government to the states (Tenth Amendment). State constitutions then create and empower local governments. Two competing legal doctrines define the boundaries of that empowerment.

Dillon’s Rule

Named after Judge John F. Dillon, this principle holds that local governments possess only those powers expressly granted by the state, implied powers necessary to carry out those grants, and powers essential to the declared objects and purposes of the corporation. Any doubt about the existence of a power is resolved against the locality. Most states follow Dillon’s Rule as a default, though many have modified it through legislation or constitutional amendments. Ballotpedia provides an overview of Dillon’s Rule and its adoption across states.

Home Rule

Home rule grants local governments autonomy to manage their own affairs without seeking state approval for every action. Typically, a state constitution or statute authorizes municipalities to adopt a home rule charter. Under home rule, local governments can pass ordinances and regulations on matters of local concern, as long as they do not conflict with general state laws. Approximately 40 states have some form of home rule authority for cities.

The tension between Dillon’s Rule and home rule shapes daily governance. In strictly Dillon’s Rule states (e.g., Virginia, Maryland, Alabama), local governments have limited flexibility. In home rule states (e.g., California, Colorado, Ohio), cities enjoy broad discretion over zoning, taxation, and local regulation, though states can still preempt them on matters of statewide concern.

The Division of Powers in Practice

Even within a given legal framework, the actual allocation of responsibilities varies. States may delegate functions to local governments, retain them centrally, or share them through intergovernmental agreements.

Exclusive State Powers

  • Setting criminal law and penalties for felony offenses.
  • Regulating intrastate commerce and corporations.
  • Establishing statewide education standards and assessment tests.
  • Managing state courts, prisons, and highways.

Shared or Concurrent Powers

  • Public health: states set guidelines; counties and cities operate clinics and respond to outbreaks.
  • Transportation: states plan and fund major highways; localities maintain city streets and public transit.
  • Environmental protection: states implement federal laws like the Clean Water Act; localities manage stormwater, waste treatment, and local air quality monitoring.
  • Emergency services: state police support local law enforcement; mutual aid agreements cross jurisdictional lines during disasters.

Fiscal Relations: The Flow of Money

State-local fiscal relations are a key lever of control. States provide substantial funding to local governments, often accompanied by mandates and conditions.

Sources of Local Revenue

Local governments raise revenue through property taxes, sales taxes (in some states), user fees, and fines. However, many are constrained by state-imposed tax and expenditure limits (TELs). For instance, California’s Proposition 13 caps property tax rates and limits assessment increases, dramatically curtailing local revenue autonomy.

State Aid and Grants

States distribute aid to localities through formulas based on population, need, or property values. The largest categories are education (state funding for school districts), transportation (road maintenance and transit), and public assistance (county-administered welfare programs). The National Association of State Budget Officers publishes annual data on intergovernmental expenditures. This financial dependence means local governments often prioritize state policy directives to secure needed funds.

Preemption and Unfunded Mandates

States sometimes impose requirements on local governments without providing the revenue to implement them—known as unfunded mandates. Examples include requiring local police to enforce state immigration laws or mandating increased teacher salaries without additional state aid. This creates fiscal strain and tension, particularly in communities with limited tax bases.

Policy Area Deep Dives

Education

Education is a state responsibility, but local school districts administer it. States set curriculum standards, testing requirements, and teacher qualifications. Local districts hire staff, manage school buildings, and in some cases raise supplementary revenue through property tax levies. The balance of power varies: states like Hawaii have a single statewide school district, while others, like Texas, rely heavily on locally elected school boards. Lawsuits over education funding equity, such as San Antonio Independent School District v. Rodriguez (1973), have shaped the dialogue between state and local authority.

Public Health

The COVID-19 pandemic highlighted the complexities of state-local health governance. States issued stay-at-home orders, mask mandates, and vaccination requirements, while local health departments conducted testing and contact tracing. Some local officials defied state directives, leading to litigation and preemption laws that stripped local health departments of authority. For example, several states passed laws prohibiting local mask mandates in schools. The American Public Health Association has documented these preemption battles and their impact on pandemic response.

Infrastructure and Transportation

State departments of transportation (DOTs) plan and fund interstate highways and major state roads. Local governments maintain local roads, bridges, and public transit systems, but often rely heavily on state and federal grants. Gas taxes, tolls, and bond measures are common funding mechanisms. In many states, local governments must submit transportation plans for state approval to access funding, giving states control over priorities even at the local level.

Criminal Justice and Policing

State governments set criminal laws, run prisons, and oversee parole. Local entities operate law enforcement agencies (police, sheriff), jails, and prosecutorial offices. Relations can be strained when state policies (such as bail reform or drug decriminalization) conflict with local enforcement practices. Conversely, local police often cooperate with state and federal agencies in task forces targeting drug trafficking or gang violence.

Challenges in the State-Local Relationship

Budget Constraints and Fiscal Disparities

Many local governments face structural deficits due to declining property tax revenues, rising pension obligations, and limited ability to raise taxes. States that impose strict TELs force localities to cut services or seek voter approval for tax increases. This dynamic can create inequities between wealthy suburbs and struggling rural or urban communities.

Preemption and Political Conflict

State preemption of local ordinances has become a flashpoint in recent years. States have passed laws preventing cities from banning plastic bags, setting minimum wages higher than the state’s, or regulating firearms. These conflicts reflect deeper ideological divides over the appropriate scope of local self-governance. The National Conference of State Legislatures tracks preemption legislation.

Coordination and Capacity Gaps

Smaller local governments often lack the staff, expertise, and technology to implement complex state or federal regulations. This can lead to inconsistent enforcement, delayed compliance, and frustrated residents. States sometimes offer technical assistance or regional compacts to address these gaps, but the problem persists in many areas.

Case Studies in State-Local Dynamics

Education Policy in New York

New York State sets rigorous learning standards and administers the Regents Exams, which are required for a high school diploma. Local school districts in New York implement these standards, but they also have substantial flexibility to design curricula, allocate resources, and offer electives. Wealthy districts supplement state aid with local property taxes, creating wide gaps in per-pupil spending between affluent and poorer districts. The state’s Foundation Aid formula attempts to equalize funding, but litigation like Campaign for Fiscal Equity v. State of New York has forced ongoing adjustments. The result is a patchwork of educational outcomes, with New York City struggling to meet state benchmarks while suburban districts consistently excel.

Public Health in California

California is a home rule state, but its Department of Public Health (CDPH) provides strong statewide guidance on immunization schedules, disease surveillance, and emergency preparedness. Local health officers in 61 local health jurisdictions implement these policies, but they also have the authority to issue local health orders. During COVID-19, counties with high case rates imposed stricter lockdowns than the state mandated, while others resisted. California also allows local governments to impose local sales taxes on sugar-sweetened beverages and other health-related products, though industry opposition has limited widespread adoption.

Infrastructure in Texas

Texas has a decentralized approach to transportation, with the Texas Department of Transportation (TxDOT) managing a 80,000-mile highway system. Local municipalities and counties maintain local roads, but major projects—such as interstate expansions, toll roads, and high-occupancy vehicle lanes—require TxDOT approval and significant state funding. The state also authorizes Regional Transportation Authorities (RTAs), like Dallas Area Rapid Transit (DART) and Houston METRO, which are local entities with state-granted power to levy sales taxes for transit. However, RTAs must submit long-range plans to TxDOT for coordination with state highway projects, and the state legislature has at times limited the ability of local governments to use public-private partnerships or to impose impact fees on developers.

Conclusion

The relationship between state and local governments is not a simple hierarchy but a interdependent partnership shaped by legal doctrines, fiscal realities, and political negotiation. States retain ultimate constitutional authority, but local governments are often the face of government for citizens. The effectiveness of this relationship depends on clear allocation of responsibilities, adequate funding, mechanisms for collaboration, and respect for local autonomy where it serves communities best. For students and educators, understanding this dynamic is essential to grasping how policies become action—and to engaging meaningfully in the civic processes that determine who really is in charge.
