Dillon's Rule
A doctrine of local government law holding that municipal corporations possess only those powers expressly granted by state law, necessarily implied by granted powers, or essential to the declared objects and purposes of the corporation. The default rule in most states absent a home rule charter.
Also known as: Dillon Rule, local government power limitation, municipal authority doctrine
Definition
Dillon's Rule is a doctrine of local government law, originating with Judge John F. Dillon's 1868 opinion in City of Clinton v. Cedar Rapids and Missouri River Railroad, providing that local governments possess only those powers (1) expressly granted by the state legislature, (2) necessarily or fairly implied from expressly granted powers, or (3) essential to the declared objects and purposes of the municipal corporation.
Historical Origin
Judge Dillon articulated the rule in City of Clinton v. Cedar Rapids and Missouri River Railroad, 24 Iowa 455 (1868), and in his treatise Municipal Corporations (1872). The U.S. Supreme Court endorsed the rule in Hunter v. Pittsburgh, 207 U.S. 161 (1907).
Practical Application in Housing
In Dillon's Rule states, a municipality may enact tenant protection ordinances (rent stabilization, just cause, screening criteria) only if:
- State law expressly authorizes such ordinances, or
- The authority is necessarily implied from other granted powers (e.g., police power for health and safety)
In Dillon's Rule states without express statutory authorization, municipalities may lack authority to enact rent control even if state law does not expressly preempt it.
Contrast with Home Rule
Home Rule jurisdictions (operating under state constitutional or statutory grants of local self-governance) may exercise broad regulatory authority without express state authorization, subject only to state preemption. Approximately half of U.S. states have some form of home rule authorization for at least some municipalities.
Housing Significance
Approximately 31 states apply Dillon's Rule to all municipalities. The rule significantly limits the ability of cities in those states to enact tenant-protective ordinances beyond what the state legislature expressly permits.
