What Is the Difference Between a Law and an Ordinance?
In the United States, a law and an ordinance are both rules that can carry legal consequences, but they differ in who creates them and where they apply. “Law” is a broad term for legally binding rules at the federal, state, and local levels. An ordinance is generally a local law adopted by a city, county, town, or other local government. Understanding that distinction can help explain why a rule applies in one community but not another—and why a local ordinance cannot always override state or federal law.
What Is a Law?
A law is a binding rule recognized and enforced by a government with authority over the people or conduct it covers. In everyday conversation, “law” often means a statute passed by a legislature. In legal usage, however, the term can also include constitutional provisions, court decisions, administrative regulations, and certain local rules.
U.S. law operates across several levels of government. The U.S. Constitution establishes the federal government and limits its powers. Congress passes federal statutes, while state legislatures enact state statutes. Federal and state agencies issue regulations under authority delegated to them by statutes. Courts interpret and apply these rules in individual cases.
Each state also has its own constitution, statutes, regulations, and court system. As a result, a rule that applies in one state may differ from the rule in another. Federal law may apply nationwide, although some federal statutes cover only specified subjects, conduct, or people.
What Is an Ordinance?
An ordinance is a local law adopted by a local government that has authority to govern a particular area. City councils, county boards, town councils, and similar governing bodies commonly pass ordinances. The precise name of the local government and the procedure it must follow vary by state and by local charter.
Ordinances often address local concerns that require rules tailored to a community. Common subjects include zoning and land use, building standards, noise, parking, public nuisances, animal control, business licensing, and local fire or safety requirements. A city might, for example, set quiet hours for residential neighborhoods or designate where certain businesses may operate.
An ordinance generally applies only within the local government’s jurisdiction and to the people, property, or activities covered by its terms. A city ordinance does not automatically apply across an entire state. A county ordinance may apply in unincorporated areas, while a city within that county may have its own rules; the boundaries and allocation of authority depend on state law.
Law vs. Ordinance: The Main Differences
| Feature | Law | Ordinance |
|---|---|---|
| Meaning | A broad term for binding rules, including statutes and other legal authorities | A local rule adopted by a municipality or other authorized local government |
| Who creates it | Depending on the type, a legislature, agency, voters, or courts may establish or shape it | Usually a local legislative body, such as a city council or county board |
| Where it applies | May apply nationally, statewide, or within a defined jurisdiction | Usually applies within the adopting local government’s boundaries |
| Typical topics | Criminal law, taxation, employment, transportation, civil rights, and many other subjects | Zoning, parking, local noise limits, property maintenance, and other local matters |
| Legal limits | Must comply with higher applicable legal authority, including the U.S. Constitution | Must comply with federal and state law and with limits on local government authority |
The comparison is not simply “important law” versus “minor rule.” An ordinance can have a substantial effect on a person’s property, business, or daily activities. The important distinction is usually the source of the rule, its geographic reach, and the authority behind it.
How Laws and Ordinances Are Made
How statutes are enacted
At the federal level, a bill generally must pass both chambers of Congress and be presented to the president, who may sign it or veto it, subject to the constitutional process for overriding a veto. State legislatures follow procedures set by their state constitutions and laws. Some states also allow voters to enact or reject certain measures through ballot initiatives or referendums.
Once enacted, a statute may direct an agency to create more detailed regulations. Those regulations are not ordinances: they are rules issued by an authorized administrative agency. The agency’s powers and procedures are limited by the statute and other applicable law.
How ordinances are enacted
Local procedures differ, but a proposed ordinance commonly goes through review, public notice or hearings when required, consideration by the governing body, and a vote. Some ordinances require additional steps, such as a supermajority vote, a referendum, or review by another local body. The local charter, state statutes, and procedural rules determine what is required.
After adoption, an ordinance may need to be published, posted, or otherwise made available before it takes effect. Local governments often maintain municipal codes that organize ordinances by subject. Those codes can be useful starting points, but the current ordinance and its effective date should be checked, especially if a rule has recently changed.
How the Legal Hierarchy Works
Local governments do not have unlimited power. Their authority comes from state constitutions, state statutes, or local charters, depending on the state’s system. An ordinance must be within the local government’s legal authority and must comply with applicable federal and state law. A local rule that conflicts with a controlling higher-level rule may be invalid or unenforceable.
The U.S. Constitution and valid federal law are generally supreme over conflicting state and local rules under the Supremacy Clause. Federal law does not automatically displace every state or local rule on the same subject, however. Courts examine the governing law and relevant facts to determine whether federal law expressly preempts local rules, occupies a field, or conflicts with them.
State law can also limit or displace local ordinances. A state may expressly prohibit local regulation of a subject, create a comprehensive statewide scheme, or establish requirements that conflict with a local rule. In some areas, a state sets minimum requirements while allowing stricter local rules; in others, it may require uniform statewide standards. The outcome depends on state law and the wording and purpose of the relevant rules.
For example, a city may regulate local parking on its streets, but it cannot authorize conduct that a controlling state or federal law prohibits. A local zoning rule may also be subject to state statutes governing land use. Whether an ordinance is preempted is a legal question, not something determined just by comparing which rule seems stricter.
How Ordinances Are Enforced
Enforcement depends on the ordinance and local procedures. A violation may result in a warning, a civil citation, a fine, a requirement to correct a condition, or a hearing before a local board or court. Certain violations may be treated as criminal offenses if state law permits and the ordinance establishes that consequence. The available penalties and procedures vary widely.
Local enforcement may be handled by police officers, code-enforcement staff, animal-control officers, licensing officials, or other authorized personnel. A citation typically identifies the alleged violation and explains how to respond, such as paying a civil penalty, correcting the issue, or contesting the citation by a deadline.
Ordinance enforcement is subject to legal safeguards. The required process depends on the type and seriousness of the penalty, the governing law, and the circumstances. A person who receives a notice should read it carefully, note deadlines, and consult the local code or issuing agency. Ignoring a citation can lead to added penalties or other consequences.
Examples of Laws and Ordinances
- Federal statute: A law enacted by Congress that establishes requirements or prohibitions within the scope of federal authority.
- State statute: A law passed by a state legislature, such as a statewide traffic requirement or licensing rule.
- City ordinance: A rule setting parking restrictions, residential noise limits, or local business requirements within city boundaries.
- County ordinance: A local rule that may apply to unincorporated areas or other areas where the county has authority, depending on state law.
- Agency regulation: A detailed rule adopted by an authorized government agency under a statute; it is distinct from an ordinance even though it can be legally binding.
These examples show why the word “law” can be broader than “ordinance.” An ordinance is one kind of local legal rule, while statutes and regulations come from different institutions and may apply over a wider area. A local rule can also be part of a municipal code, while a state statute appears in a state code.
How to Find Out Which Rule Applies
When a legal question concerns a local requirement, the location matters. Start by identifying the relevant city, county, or other jurisdiction, and determine whether the property or activity is inside its boundaries. Nearby communities may have different rules, and city limits do not always match postal addresses.
- Identify the subject and location. Note whether the issue concerns property, a business, public conduct, traffic, or another topic, and where it occurred.
- Check the official local code. Search the city or county government’s website for its municipal code, ordinance, or official notices. Confirm the rule’s current text and effective date.
- Review state and federal requirements. Look for relevant statutes or agency guidance through official government sources, such as state legislature websites, agency websites, or the U.S. Code.
- Check for exceptions and procedures. Definitions, permits, exemptions, appeal rights, and deadlines can change how a rule applies.
- Seek qualified help when needed. For a serious penalty, property dispute, or uncertain conflict between rules, an attorney or the responsible government office can clarify the applicable process.
Search results and summaries can help locate a rule, but they may be outdated or omit exceptions. Official code publications and the text of the law are more reliable than an informal description. For a specific citation or dispute, the notice itself and the jurisdiction’s current procedures are especially important.
Common Misunderstandings
“An ordinance is not really a law”
An ordinance is generally a form of local law when it is validly adopted under the government’s authority. Calling it “local” does not make it optional. Its enforceability depends on the governing law, the ordinance’s wording, and whether the local government followed required procedures.
“State law always overrides local rules”
Not in every situation. States may reserve some subjects for statewide regulation, but they may also delegate authority to local governments or allow local rules alongside state requirements. The relevant state constitution, statutes, and court decisions determine the boundaries.
“Every violation leads to a criminal record”
Many ordinance violations are handled as civil or administrative matters, but some can carry criminal penalties where authorized. The citation, local code, and applicable state law indicate the classification and potential consequences. A fine should not automatically be assumed to be either civil or criminal.
Why the Distinction Matters
Knowing the difference between a law and an ordinance helps people identify which government made a rule, where it applies, and where to verify its requirements. A local ordinance may govern an everyday issue such as parking or property maintenance, while state or federal law may set broader standards or limit local authority. Checking the correct jurisdiction and the current official text is the most practical way to understand a rule before acting on it.
