Government authority in the United States is not unlimited. The federal government operates within the powers the Constitution grants to it. State governments exercise broad authority, but they operate within both the federal Constitution and their own state constitutions. Local governments in California exercise only the authority state law grants to them.
That structure of divided and limited authority is not accidental. The Framers designed a system in which different levels of government check each other. The 10th Amendment reflects that design. It reserves to states, and to the people, the powers not delegated to the federal government by the Constitution.
For California property owners, businesses, and individuals dealing with government regulation, this constitutional structure has practical consequences. The structure determines which level of government can regulate a given activity. It also defines when federal law overrides state law and when state law overrides local rules. These principles help determine when government action at any level may exceed constitutional limits.
What the 10th Amendment Actually Says
The 10th Amendment states: “The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.” The language is straightforward. What it means in practice has been the subject of constitutional interpretation for more than two centuries. The phrase “or to the people” reflects the Framers’ intent that residual power belongs not only to state governments but also to individuals , a point that courts address primarily through the Bill of Rights rather than the 10th Amendment itself.
Put simply: the 10th Amendment limits what the federal government may do by reserving everything else to the states or the people. The 10th Amendment does not grant states any new authority. It reflects the principle that the federal government possesses only enumerated powers. If the Constitution does not grant a power to the federal government, the states retain it, provided the Constitution does not prohibit it to the states.
Courts have interpreted the 10th Amendment as reflecting a structural constitutional commitment to federalism. The federal government and state governments each operate in their respective spheres. Neither one is simply a branch of the other. In most regulatory contexts, however, courts rely on the political process rather than judicial invalidation to protect that balance. The anti-commandeering doctrine, discussed below, is a recognized judicial exception.
Federal Power, State Power, and Where the Lines Are Drawn
What the Federal Government Can Do
The U.S. Constitution grants Congress specific powers. These include regulating commerce among the states, imposing taxes, coining money, and providing for national defense. The Supremacy Clause of Article VI establishes that federal law made within those powers is the supreme law of the land. Where valid federal law conflicts with state law, federal law controls.
Courts examine both whether Congress had authority to enact a particular law and whether that law actually conflicts with state regulation. Both questions require close analysis of the constitutional provision at issue and the specific laws involved.
The Anti-Commandeering Doctrine
One concrete application of 10th Amendment principles is the anti-commandeering doctrine. In plain terms, this doctrine holds that the federal government cannot compel state legislatures or executive officials to administer or enforce federal law. The Supreme Court held in New York v. United States, 505 U.S. 144 (1992) that Congress cannot compel state legislatures to enact or enforce a federal regulatory program. It confirmed this principle in Printz v. United States, 521 U.S. 898 (1997), holding that the federal government cannot direct state executive officers to administer or enforce federal law. The federal government may incentivize state cooperation, but it may not commandeer state governments as instruments of federal policy.
This doctrine shapes the relationship between federal programs and state administration. It does not prevent federal regulation of private parties. It addresses the specific issue of compelling state governments to carry out federal mandates.
Preemption: When Federal Law Overrides State Law
Even within its enumerated powers, the federal government does not automatically override state law on the same subject. Courts analyze whether Congress intended to preempt state regulation in three ways.
Express preemption occurs when a federal statute explicitly states that it supersedes state law. Implied field preemption occurs when federal regulation is so pervasive that Congress left no room for state regulation in that area. Conflict preemption occurs when complying with both laws simultaneously is impossible. It also applies when state law obstructs federal objectives.
In California, preemption disputes arise in areas such as telecommunications regulation, agricultural water use, and certain transportation law matters. Environmental law presents a distinct pattern: California sometimes receives federal waivers to set stricter environmental standards rather than being preempted by federal ones. Whether a particular state regulation survives preemption analysis depends on the specific federal statute and the subject matter regulated.
State Police Power: The Broad Base of State Authority
States retain the general police power: the authority to regulate for the health, safety, welfare, and morals of their residents. This power has no precise outer boundary. The Supreme Court has recognized it as one of the broadest grants of authority in American constitutional law.
California exercises its police power through an extensive regulatory framework. Environmental regulation, land use planning, building codes, professional licensing, and public health requirements all flow from this general authority. The police power is subject to federal constitutional limits, but within those limits, state regulatory authority is substantial.
California’s Internal Structure: State Authority Over Local Governments
How Local Government Authority Works in California
The 10th Amendment addresses the relationship between federal and state authority. Within California, a different constitutional structure governs the relationship between the state and its local governments.
California local governments derive their authority from the state, not from any inherent power. For general law cities and counties, courts apply what is sometimes called Dillon’s Rule: local governments possess only the powers the state expressly grants, necessarily implies, or recognizes as indispensable to local government functions. The California Constitution addresses the allocation of authority between state and local governments in Article XI.
Charter Cities and General Law Cities
California distinguishes between general law cities and charter cities. General law cities operate under the authority granted by the California Government Code. They must follow state law on most matters.
Charter cities adopt their own charters, which function as local constitutions. On matters of purely municipal affairs, a charter city’s ordinance controls over conflicting state law. But the line between a municipal affair and a matter of statewide concern is often contested. Courts determine that line case by case, based on the nature and subject of the regulation.
Where state law addresses a matter of statewide concern, it overrides local ordinances from both general law cities and charter cities. California’s recent housing legislation has generated extensive litigation about where local control ends and state housing policy begins.
County Authority in California
California counties are creatures of the state. They exercise the authority granted by the California Constitution and the Government Code. Unlike charter cities, counties do not have a separate police power and generally cannot act beyond what the state expressly authorizes.
County land use and zoning authority comes from state planning law. The California Planning and Zoning Law, codified at Government Code section 65000 et seq., provides that framework. Within that framework, counties exercise substantial discretion. But that discretion has statutory limits.
How These Constitutional Principles Affect Property Owners and Businesses
State Preemption of Local Land Use Decisions
California’s recent housing legislation exemplifies how state law preempts local authority. Statutes like the Housing Accountability Act and SB 330 restrict what cities and counties can require. They apply to qualifying residential project approvals.
A city that denies a project in violation of these state mandates faces the possibility that the denial itself violates state law. The state’s housing policy, expressed through these statutes, controls over conflicting local ordinance. Courts have enforced that hierarchy.
Where a local agency uses slow-growth policies or permit restrictions to block development in ways that conflict with state law, those restrictions may not survive legal challenge. An overview of how growth controls interact with property rights is at the firm’s article on Growth Controls in California: How Slow-Growth Ordinances Affect Property Rights.
When Local Government Exceeds Its Authority
Local government authority in California has defined limits. A city or county that acts beyond those limits faces potential challenge through administrative proceedings and judicial review.
A local agency that denies a permit on grounds not authorized by state law, or that applies a standard not supported by the governing statute, acts outside the scope of its delegated authority. Courts examine whether the agency acted within its jurisdiction when reviewing local land use decisions.
Judicial review of local agency decisions through writ of administrative mandate is an important mechanism for property owners facing government decisions that exceed statutory authority. The firm’s overview of this process is at Writ of Administrative Mandate in California Land Use Law.
Federal Constitutional Limits on State and Local Regulation
Both state and local governments must comply with the federal Constitution regardless of their reserved powers. The 10th Amendment does not protect state or local governments from federal constitutional requirements.
State and local governments may not violate the First Amendment, the Fourth Amendment, the Takings Clause, or the Due Process and Equal Protection Clauses of the Fourteenth Amendment. These constraints apply to federal, state, and local government actors alike.
Claims against government officials who violate constitutional rights may be brought under 42 U.S.C. § 1983. The firm’s overview of how these civil rights claims work is at the article on Section 1983 claims in California.
Historic Designation and the Limits of Local Authority
The question of when local authority to designate historic resources conflicts with state housing law illustrates how these layers interact. California law addresses whether a city can use historic designation to block a qualifying housing application after the application is filed. The firm addresses the legal framework for that question at Can a City Designate a Property Historic After a Housing Application Is Filed?.
The California Constitution and the 10th Amendment
California operates under both the U.S. Constitution and its own state constitution. The California Constitution establishes the structure of state government, defines the rights of California residents, and in many areas provides protections that go beyond the minimum federal standards. The relationship between these two constitutional frameworks is discussed at The California Constitution and the U.S. Constitution.
California’s own constitutional provisions, including the provisions governing land use, property rights, and local government authority, operate within the federal constitutional structure. State constitutional provisions that conflict with the federal Constitution do not control. But where the California Constitution provides greater protection than the federal Constitution, the state provision applies.
Article I, Section 19 of the California Constitution provides broader protection for property owners facing government condemnation than the federal Takings Clause in some respects. California courts have interpreted “damaged” as well as “taken” to require compensation in appropriate circumstances.

The Role of Judicial Review
Courts determine how to resolve conflicts between federal authority, state authority, and local authority. Judicial review of government decisions is a foundational constitutional principle. Courts examine whether government action exceeds constitutional or statutory limits. That function is discussed at The Constitutional Right of Judicial Review.
Both federal and state courts exercise this function. Federal courts resolve disputes about the scope of federal authority and about compliance with the federal Constitution. State courts resolve disputes about California constitutional and statutory limits on state and local government action.
Courts do not substitute their policy judgment for that of the legislative or executive branch. They determine whether the government acted within the legal authority it possesses. Where it did not, courts have authority to set aside the unlawful action.
What This Means for California Property Owners and Businesses
Understanding the constitutional structure of government authority has practical significance for California property owners, developers, and businesses.
A regulation that a local agency imposes without statutory authority may be challengeable regardless of its policy merit. A state law that conflicts with a valid federal statute may not control. A government action that violates federal constitutional requirements may expose government officials or entities to liability.
They shape whether a permit denial is lawful, whether a zoning condition exceeds the agency’s authority, and whether a property owner has legal recourse when government action causes economic harm.
Kassouni Law’s constitutional litigation practice covers disputes arising from government actions that may implicate constitutional limits. The firm handles matters involving constitutional rights, including issues related to Constitutional Law, Civil Rights, and government authority. These disputes may also overlap with property and regulatory matters involving Land Use Law, Zoning Law, and Development Law. The firm represents private parties in constitutional disputes and does not represent government agencies.
Constitutional Structure in Land Use and Property Disputes
Constitutional limits on government authority appear most visibly in land use and property rights disputes. Courts regularly adjudicate questions about whether a local agency’s decision falls within state statutory authority, whether a state statute conflicts with federal housing or environmental law, and whether a government action violates federal constitutional provisions. The firm’s overview of government and land use constitutional matters is at Constitutional Law: Government and Land Use Matters.
A property owner challenging a permit denial raises questions about the scope of local government authority. A developer challenging a zoning condition may raise both state statutory and federal constitutional issues. A landowner facing government acquisition may invoke both the federal Takings Clause and California’s inverse condemnation doctrine simultaneously.
These layered constitutional and statutory frameworks require precise analysis. The applicable authority at each level, the specific provision at issue, and the facts of the government action all shape what legal arguments are available and how likely they are to succeed.

Frequently Asked Questions
1. What does the 10th Amendment mean for California residents?
The 10th Amendment provides that powers not granted to the federal government by the Constitution are reserved to the states or the people. In practice, this means California and other states retain broad authority to regulate health, safety, welfare, and public morals through the state police power. It also means the federal government must act within its enumerated constitutional powers. When Congress acts beyond those powers, or when it attempts to compel states to administer federal programs, courts may invalidate the federal action under 10th Amendment principles. For California residents, the most practical significance is the layered structure of federal, state, and local authority that governs regulation of land use, business, and private activity.
2. Can a California city or county act beyond what state law authorizes?
Generally, no. California local governments derive their authority from the state. They possess only the powers state law grants them expressly, implies necessarily, or recognizes as indispensable to local government functions. A local ordinance that exceeds this delegated authority may be challenged through administrative appeal and judicial review. Charter cities have somewhat broader authority on matters of purely municipal affairs, but even charter cities must follow state law on matters of statewide concern. California courts determine the boundary between municipal affairs and statewide concerns on a case-by-case basis.
3. When does federal law override California state law?
Federal law overrides California state law when two conditions are met. First, the federal law must be within Congress’s enumerated constitutional powers. Second, the federal law must either expressly preempt state law, occupy the regulatory field so pervasively that no room remains for state regulation, or conflict with state law in a way that makes simultaneous compliance impossible. The Supremacy Clause of Article VI establishes federal supremacy over state law within these limits. Courts analyze the specific federal statute and the specific state regulation to determine whether preemption applies. Not every federal statute preempts related state law.
4. How does the 10th Amendment connect to property rights disputes in California?
Constitutional structure shapes property rights disputes at multiple levels. A local permit denial may exceed the agency’s delegated authority under state law. A state regulatory requirement may conflict with federal law or the federal Constitution. A government action that takes or damages property may implicate the federal Takings Clause, Article I, Section 19 of the California Constitution, or both. Evaluating a property rights dispute requires identifying which level of government is involved, what authority that government actually has, and whether the action complies with applicable constitutional and statutory limits. Courts review these questions through judicial review of agency decisions and, where applicable, through constitutional litigation.
5. What is the anti-commandeering doctrine and how does it work?
The anti-commandeering doctrine holds that the federal government cannot compel state legislatures or state executive officials to implement or administer federal law. The Supreme Court developed this principle in New York v. United States, 505 U.S. 144 (1992) and Printz v. United States, 521 U.S. 898 (1997). The doctrine does not prevent Congress from regulating private parties directly under its enumerated powers. It prevents Congress from using state governments as instruments of federal policy. The federal government may offer incentives to states that adopt federal standards, but it may not commandeer state officials to carry out federal directives. This structural principle reflects the 10th Amendment’s protection of state sovereignty within the federal system.
